[pgrouting-users] pgrouting Dijksta Travelling Salesman Problem (TSP) with OpenStreetmap

pgRouting pgrouting-users
1

Hi everybody, I am new to this list and new to pgrouting.

I found the following TSP example http://hardwarefetish.com/513-pgrouting-dijksta-travelling-salesman-problem-tsp-with-openstreetmap
and tried to reproduce the solution.

Unfortunately I always get an error message.
My DB is complaining about one of your functions.

I got my routing table from osm2po. The table has the following structure:

1;”id”;”integer”
2;”osm_id”;”bigint”
3;”osm_name”;”character varying”
4;”osm_meta”;”character varying”
5;”osm_source_id”;”bigint”
6;”osm_target_id”;”bigint”;
7;”clazz”;”integer”
8;”flags”;”integer”
9;”source”;”integer”
10;”target”;”integer”
11;”length”;”double precision”
12;”kmh”;”integer”
13;”cost”;”double precision”
14;”reverse_cost”;”double precision”
15;”x1″;”double precision”
16;”y1″;”double precision”
17;”x2″;”double precision”
18;”y2″;”double precision”
19;”geom_way”;”geometry(LineString,4326)”

  • I installed the functions as mentioned via SQL window in pgAdmin3 (copy&paste then excecute)
  • I create and populate the my_route table
  • When it comes to step 5 and I try

select id,lon,lat from pgr_tspDijkstraLen(’my_route’, 1260
) dj, my_route rt where dj.id2=rt.node;

my DB warns

ERROR: cannot concatenate incompatible arrays
DETAIL: Arrays with differing element dimensions are not compatible for concatenation.
CONTEXT: PL/pgSQL function “pgr_makedijkstramatrix” line 25 at assignment PL/pgSQL function “pgr_tspdijkstra” line 8 at RETURN QUERY

Hi Carsten,

The functions at
   http://dose.0wnz.at/scripts/sql/pgroute_tspDijkstra.sql
are not part of pgRouting.

You need to ask this question to Ivan the author of the original article.

You probably need to add some debug statements to get a better understanding of what the code is doing. For example in pgr_makeDijkstraMatrix before the statement:

ids := ids || array[r2.id1];

Add:

raise notice 'r2: %', r2;
raise notice 'r2.id1: %', r2.id1;
raise notice 'ids: %', ids;

This should show you the progression of how the array ids is getting built as it appears to be compaining about that in the error message.

Hope this helps,
   -Steve

solutionget working. I would appreciate a lot.

Thanks for your help.

PS: this text is a copy of what I wrote on on the comment site of the
blog where I found the solution.

I tried to write to Dose but he didn't reply yet.
Does anyone have a clue?

Try adding the follow line after the "begin" line:

    ids := '{}'::integer;

This should make sure the ids is initialized as an empty array of integers.

Thanks for you help

        Hi Carsten,

        The functions at

        <http://dose.0wnz.at/scripts/sql/pgroute_tspDijkstra.sql&gt;
        are not part of pgRouting.

        You need to ask this question to Ivan the author of the original
        article.

    Sorry, Dose was the original author.

        You probably need to add some debug statements to get a better
        understanding of what the code is doing. For example in
        pgr_makeDijkstraMatrix before the statement:

        ids := ids || array[r2.id1];

    You could try changing this line to:

    ids := ids || r2.id1;

    and see if that fixes the problem.

    -Steve

        Add:

        raise notice 'r2: %', r2;
        raise notice 'r2.id1: %', r2.id1;
        raise notice 'ids: %', ids;

        This should show you the progression of how the array ids is getting
        built as it appears to be compaining about that in the error
        message.

        Hope this helps,
            -Steve

I tried to write to Dose but he didn't reply yet.
Does anyone have a clue?

Try adding the follow line after the "begin" line:

   ids := '{}'::integer;

This should make sure the ids is initialized as an empty array of integers.

        Hi Carsten,

        The functions at

        are not part of pgRouting.

        You need to ask this question to Ivan the author of the original
        article.

    Sorry, Dose was the original author.

        You probably need to add some debug statements to get a better
        understanding of what the code is doing. For example in
        pgr_makeDijkstraMatrix before the statement:

        ids := ids || array[r2.id1];

    You could try changing this line to:

    ids := ids || r2.id1;

    and see if that fixes the problem.

    -Steve

        Add:

        raise notice 'r2: %', r2;
        raise notice 'r2.id1: %', r2.id1;
        raise notice 'ids: %', ids;

        This should show you the progression of how the array ids is
getting
        built as it appears to be compaining about that in the error
        message.

        Hope this helps,
            -Steve

        I tried to write to Dose but he didn't reply yet.
        Does anyone have a clue?

    Try adding the follow line after the "begin" line:

        ids := '{}'::integer;

    This should make sure the ids is initialized as an empty array of
    integers.

Thanks for your help. Maybe you need some other facts about my table?
The whole script I am excecuting is the following. I changed some
things, like adding your code and changing the table name 'ways' to
'cgn_2po_4pgr':

               ', (select array_agg(node) from '||thetbl||' where
id>'||r.id <http://r.id>||'), false, false)
          ) as foo group by id1 order by id1';
         for r2 in execute sql2 loop
         matrixl := '{}';
         for i in 1..r.id <http://r.id> loop
                   matrixl := array_append(matrixl, dmatrix[i][r.id

                 end loop;
                 matrixl := array_cat(matrixl, r2.arow);
             dmatrix := array_cat(dmatrix, array[matrixl]);
             raise notice 'r2: %', r2;
raise notice 'r2.id1: %', r2.id1;
raise notice 'ids: %', ids;

Sorry, I don't have a running version of this so this is somewhat guess work.

              -- ids := ids || r2.id1;
                ids := array_cat(ids, r2.id1);

So comment out the old like and rewrite like this.

                 You need to ask this question to Ivan the author of the
        original
                 article.

             Sorry, Dose was the original author.

                 You probably need to add some debug statements to get a
        better
                 understanding of what the code is doing. For example in
                 pgr_makeDijkstraMatrix before the statement:

                 ids := ids || array[r2.id1];

             You could try changing this line to:

             ids := ids || r2.id1;

             and see if that fixes the problem.

             -Steve

                 Add:

                 raise notice 'r2: %', r2;
                 raise notice 'r2.id1: %', r2.id1;
                 raise notice 'ids: %', ids;

                 This should show you the progression of how the array
        ids is getting
                 built as it appears to be compaining about that in the
        error
                 message.

                 Hope this helps,

                     and tried to reproduce the solution.

                     Unfortunately I always get an error message.
                     My DB is complaining about one of your functions.

                     I got my routing table from osm2po. The table has
        the following
                     structure:

                     1;”id”;”integer”
                     2;”osm_id”;”bigint”
                     3;”osm_name”;”character varying”
                     4;”osm_meta”;”character varying”
                     5;”osm_source_id”;”bigint”
                     6;”osm_target_id”;”bigint”;
                     7;”clazz”;”integer”
                     8;”flags”;”integer”
                     9;”source”;”integer”
                     10;”target”;”integer”
                     11;”length”;”double precision”
                     12;”kmh”;”integer”
                     13;”cost”;”double precision”
                     14;”reverse_cost”;”double precision”
                     15;”x1″;”double precision”
                     16;”y1″;”double precision”
                     17;”x2″;”double precision”
                     18;”y2″;”double precision”
                     19;”geom_way”;”geometry(____LineString,4326)”

                     - I installed the functions as mentioned via SQL
        window in
                     pgAdmin3
                     (copy&paste then excecute)
                     - I create and populate the my_route table
                     - When it comes to step 5 and I try

                     select id,lon,lat from
        pgr_tspDijkstraLen(’my_route’, 1260
                     ) dj, my_route rt where dj.id2=rt.node;

                     my DB warns

                     ERROR: cannot concatenate incompatible arrays
                     DETAIL: Arrays with differing element dimensions
        are not
                     compatible for
                     concatenation.

                     Do you have any idea what went wrong? I really
        really need your
                     solutionget working. I would appreciate a lot.

                     Thanks for your help.

                     PS: this text is a copy of what I wrote on on the
        comment
                     site of the
                     blog where I found the solution.

        I tried to write to Dose but he didn't reply yet.
        Does anyone have a clue?

    Try adding the follow line after the "begin" line:

        ids := '{}'::integer;

    This should make sure the ids is initialized as an empty array of
    integers.

Thanks for your help. Maybe you need some other facts about my table?
The whole script I am excecuting is the following. I changed some
things, like adding your code and changing the table name 'ways' to
'cgn_2po_4pgr':

create or replace function pgr_makeDijkstraMatrix(thetbl text, sqlP
text, OUT dmatrix double precision, OUT ids integer)
   as
$body$
declare
     sql text;
     sql2 text;
     r record;
     r2 record;
     i integer;
     j integer;
     matrixl double precision;
begin

    ids := '{}'::integer;
     sql:='select node, id-1 as id from '||thetbl;
     for r in execute sql loop
             sql2:='select id1, array_agg(cost) as arow from (
           SELECT id1, id2, cost
           FROM pgr_kdijkstraCost('''||sqlP||''', '||r.node||
               ', (select array_agg(node) from '||thetbl||' where
id>'||r.id <http://r.id>||'), false, false)

          ) as foo group by id1 order by id1';
         for r2 in execute sql2 loop
         matrixl := '{}';
         for i in 1..r.id <http://r.id> loop

                   matrixl := array_append(matrixl, dmatrix[i][r.id
<http://r.id>+1]);

                 end loop;
                 matrixl := array_cat(matrixl, r2.arow);
             dmatrix := array_cat(dmatrix, array[matrixl]);
             raise notice 'r2: %', r2;
raise notice 'r2.id1: %', r2.id1;
raise notice 'ids: %', ids;

Sorry, I don't have a running version of this so this is somewhat guess
work.

             -- ids := ids || r2.id1;
               ids := array_cat(ids, r2.id1);

So comment out the old like and rewrite like this.

                 You need to ask this question to Ivan the author of the
        original
                 article.

             Sorry, Dose was the original author.

                 You probably need to add some debug statements to get a
        better
                 understanding of what the code is doing. For example in
                 pgr_makeDijkstraMatrix before the statement:

                 ids := ids || array[r2.id1];

             You could try changing this line to:

             ids := ids || r2.id1;

             and see if that fixes the problem.

             -Steve

                 Add:

                 raise notice 'r2: %', r2;
                 raise notice 'r2.id1: %', r2.id1;
                 raise notice 'ids: %', ids;

                 This should show you the progression of how the array
        ids is getting
                 built as it appears to be compaining about that in the
        error
                 message.

                 Hope this helps,

                 I tried to write to Dose but he didn't reply yet.
                 Does anyone have a clue?

             Try adding the follow line after the "begin" line:

                 ids := '{}'::integer;

             This should make sure the ids is initialized as an empty
        array of
             integers.

        Thanks for your help. Maybe you need some other facts about my
        table?
        The whole script I am excecuting is the following. I changed some
        things, like adding your code and changing the table name 'ways' to
        'cgn_2po_4pgr':

        create or replace function pgr_makeDijkstraMatrix(thetbl text, sqlP
        text, OUT dmatrix double precision, OUT ids integer)
            as
        $body$
        declare
              sql text;
              sql2 text;
              r record;
              r2 record;
              i integer;
              j integer;
              matrixl double precision;
        begin

             ids := '{}'::integer;
              sql:='select node, id-1 as id from '||thetbl;
              for r in execute sql loop
                      sql2:='select id1, array_agg(cost) as arow from (
                    SELECT id1, id2, cost
                    FROM pgr_kdijkstraCost('''||sqlP||'__'', '||r.node||
                        ', (select array_agg(node) from '||thetbl||' where
        id>'||r.id <http://r.id> <http://r.id>||'), false, false)

                   ) as foo group by id1 order by id1';
                  for r2 in execute sql2 loop
                  matrixl := '{}';
                  for i in 1..r.id <http://r.id> <http://r.id> loop

                            matrixl := array_append(matrixl,
        dmatrix[i][r.id <http://r.id>
        <http://r.id>+1]);

                          end loop;
                          matrixl := array_cat(matrixl, r2.arow);
                      dmatrix := array_cat(dmatrix, array[matrixl]);
                      raise notice 'r2: %', r2;
        raise notice 'r2.id1: %', r2.id1;
        raise notice 'ids: %', ids;

    Sorry, I don't have a running version of this so this is somewhat
    guess work.

                  -- ids := ids || r2.id1;
                    ids := array_cat(ids, r2.id1);

try changing the line above to:

                       ids := array_cat(ids, array[r2.id1]);

    So comment out the old like and rewrite like this.

                          You need to ask this question to Ivan the
        author of the
                 original
                          article.

                      Sorry, Dose was the original author.

                          You probably need to add some debug statements
        to get a
                 better
                          understanding of what the code is doing. For
        example in
                          pgr_makeDijkstraMatrix before the statement:

                          ids := ids || array[r2.id1];

                      You could try changing this line to:

                      ids := ids || r2.id1;

                      and see if that fixes the problem.

                      -Steve

                          Add:

                          raise notice 'r2: %', r2;
                          raise notice 'r2.id1: %', r2.id1;
                          raise notice 'ids: %', ids;

                          This should show you the progression of how
        the array
                 ids is getting
                          built as it appears to be compaining about
        that in the
                 error
                          message.

                          Hope this helps,
                              -Steve

                 I tried to write to Dose but he didn't reply yet.
                 Does anyone have a clue?

             Try adding the follow line after the "begin" line:

                 ids := '{}'::integer;

             This should make sure the ids is initialized as an empty
        array of
             integers.

        Thanks for your help. Maybe you need some other facts about my
        table?
        The whole script I am excecuting is the following. I changed some
        things, like adding your code and changing the table name 'ways'
to
        'cgn_2po_4pgr':

        create or replace function pgr_makeDijkstraMatrix(thetbl text,
sqlP
        text, OUT dmatrix double precision, OUT ids integer)
            as
        $body$
        declare
              sql text;
              sql2 text;
              r record;
              r2 record;
              i integer;
              j integer;
              matrixl double precision;
        begin

             ids := '{}'::integer;
              sql:='select node, id-1 as id from '||thetbl;
              for r in execute sql loop
                      sql2:='select id1, array_agg(cost) as arow from (
                    SELECT id1, id2, cost
                    FROM pgr_kdijkstraCost('''||sqlP||'__'', '||r.node||

                        ', (select array_agg(node) from '||thetbl||' where
        id>'||r.id <http://r.id> <http://r.id>||'), false, false)

                   ) as foo group by id1 order by id1';
                  for r2 in execute sql2 loop
                  matrixl := '{}';
                  for i in 1..r.id <http://r.id> <http://r.id> loop

                            matrixl := array_append(matrixl,
        dmatrix[i][r.id <http://r.id>
        <http://r.id>+1]);

                          end loop;
                          matrixl := array_cat(matrixl, r2.arow);
                      dmatrix := array_cat(dmatrix, array[matrixl]);
                      raise notice 'r2: %', r2;
        raise notice 'r2.id1: %', r2.id1;
        raise notice 'ids: %', ids;

    Sorry, I don't have a running version of this so this is somewhat
    guess work.

                  -- ids := ids || r2.id1;
                    ids := array_cat(ids, r2.id1);

try changing the line above to:

                      ids := array_cat(ids, array[r2.id1]);

Hi Steve, thank you. Back in office now but I'll try that later at home.
I'll let you know and hopefully I get a good result :slight_smile:
Thanks so much.
Carsten

    So comment out the old like and rewrite like this.

    -Steve

Thanks for all your help Steve,
hope, we're getting closer! Look, not it returns this:

        Maybe you've got another idea?

                          are not part of pgRouting.

                          You need to ask this question to Ivan the
        author of the
                 original
                          article.

                      Sorry, Dose was the original author.

                          You probably need to add some debug statements
        to get a
                 better
                          understanding of what the code is doing. For
        example in
                          pgr_makeDijkstraMatrix before the statement:

                          ids := ids || array[r2.id1];

                      You could try changing this line to:

                      ids := ids || r2.id1;

                      and see if that fixes the problem.

                      -Steve

                          Add:

                          raise notice 'r2: %', r2;
                          raise notice 'r2.id1: %', r2.id1;
                          raise notice 'ids: %', ids;

                          This should show you the progression of how
        the array
                 ids is getting
                          built as it appears to be compaining about
        that in the
                 error
                          message.

                          Hope this helps,
                              -Steve

Hi Steve,

have been busy the last days so I only check your Thursday’s solution right now. Still not working.

My function looks like this:

create or replace function pgr_makeDijkstraMatrix(thetbl text, sqlP text, OUT dmatrix double precision, OUT ids integer)
as
$body$
declare
sql text;
sql2 text;
r record;
r2 record;
i integer;
j integer;
matrixl double precision;
begin

ids := ‘{}’::integer;
sql:=‘select node, id-1 as id from ‘||thetbl;
for r in execute sql loop
sql2:=‘select id1, array_agg(cost) as arow from (
SELECT id1, id2, cost
FROM pgr_kdijkstraCost(’’’||sqlP||‘’‘, ‘||r.node||
‘, (select array_agg(node) from ‘||thetbl||’ where id>’||r.id||’), false, false)
) as foo group by id1 order by id1’;
for r2 in execute sql2 loop
matrixl := ‘{}’;
for i in 1…r.id loop
matrixl := array_append(matrixl, dmatrix[i][r.id+1]);
end loop;
matrixl := array_cat(matrixl, r2.arow);
dmatrix := array_cat(dmatrix, array[matrixl]);
raise notice ‘r2: %’, r2;
raise notice ‘r2.id1: %’, r2.id1;
raise notice ‘ids: %’, ids;
–ids := ids || r2.id1;
ids := array_cat(ids, array[r2.id1]);
end loop;
end loop;
end;
$body$
language plpgsql stable cost 10;

create or replace function pgr_tspDijkstra(thetbl text, sql text, start_id integer, end_id integer default (-1))
returns setof pgr_costResult as
$body$
declare
sid integer;
eid integer;

begin

return query with dm as (
select * from pgr_makeDijkstraMatrix( thetbl, sql )
),
ids as (
select (row_number() over (order by id asc))-1 as rnum, id
from (
select unnest(ids) as id
from dm
) foo
),
t as (
select a.seq, b.rnum, b.id
from pgr_tsp(
(select dmatrix from dm),
(select rnum from ids where id=start_id limit 1)::integer,
(case when end_id = -1 then -1 else (select rnum from ids where id=end_id limit 1) end)::integer
) a,
ids b
where a.id=b.rnum
),
r as (
select array_agg(t.rnum) as rnum from t
)

from t, dm, r;
end;
$body$
language plpgsql volatile cost 50 rows 50;

create or replace function pgr_tspDijkstraLen(thetbl text, start_id integer, end_id integer default (-1))
returns setof pgr_costResult as
$body$
begin
return query SELECT * FROM pgr_tspDijkstra(thetbl,
‘SELECT id, source::integer, target::integer, length::double precision AS cost FROM cgn_2po_4pgr’,
start_id, end_id);
end;
$body$

I tried to write to Dose but he didn’t reply yet.
Does anyone have a clue?

Try adding the follow line after the “begin” line:

This should make sure the ids is initialized as an empty
array of
integers.

Thanks for your help. Maybe you need some other facts about my
table?
The whole script I am excecuting is the following. I changed some
things, like adding your code and changing the table name ‘ways’ to
‘cgn_2po_4pgr’:

create or replace function pgr_makeDijkstraMatrix(thetbl text, sqlP
text, OUT dmatrix double precision, OUT ids integer)
as
$body$
declare
sql text;
sql2 text;
r record;
r2 record;
i integer;
j integer;
matrixl double precision;
begin

ids := ‘{}’::integer;
sql:='select node, id-1 as id from '||thetbl;
for r in execute sql loop
sql2:='select id1, array_agg(cost) as arow from (
SELECT id1, id2, cost

FROM pgr_kdijkstraCost(‘’‘||sqlP||’__‘’, '||r.node||

', (select array_agg(node) from ‘||thetbl||’ where

id>‘||r.id <http://r.id> <http://r.id>||’), false, false)

) as foo group by id1 order by id1’;
for r2 in execute sql2 loop
matrixl := ‘{}’;

for i in 1…r.id <http://r.id> <http://r.id> loop

matrixl := array_append(matrixl,
dmatrix[i][r.id <http://r.id>
<http://r.id>+1]);

end loop;
matrixl := array_cat(matrixl, r2.arow);
dmatrix := array_cat(dmatrix, array[matrixl]);
raise notice ‘r2: %’, r2;
raise notice ‘r2.id1: %’, r2.id1;
raise notice ‘ids: %’, ids;

Sorry, I don’t have a running version of this so this is somewhat
guess work.

– ids := ids || r2.id1;
ids := array_cat(ids, r2.id1);

try changing the line above to:

ids := array_cat(ids, array[r2.id1]);

Hi Steve, thank you. Back in office now but I’ll try that later at home.
I’ll let you know and hopefully I get a good result :slight_smile:
Thanks so much.

Carsten

So comment out the old like and rewrite like this.

-Steve

Thanks for all your help Steve,
hope, we’re getting closer! Look, not it returns this:

are not part of pgRouting.

You need to ask this question to Ivan the
author of the
original
article.

Sorry, Dose was the original author.

You probably need to add some debug statements
to get a
better
understanding of what the code is doing. For
example in
pgr_makeDijkstraMatrix before the statement:

ids := ids || array[r2.id1];

You could try changing this line to:

ids := ids || r2.id1;

and see if that fixes the problem.

-Steve

Add:

raise notice ‘r2: %’, r2;
raise notice ‘r2.id1: %’, r2.id1;
raise notice ‘ids: %’, ids;

This should show you the progression of how
the array
ids is getting
built as it appears to be compaining about
that in the
error
message.

Hope this helps,
-Steve

I'm busy for the next few days so I will not have time to look at it until later this week.

What version of postgresql are you running?

select * from version();

I would google "postgresql array functions" and read up on these.There is a function that will tell you the dimensions of an array and maybe you need to print out some more notices to figure out what it is expecting.

Maybe someone else on the list wants to take a crack at this.

Thanks,

                              I tried to write to Dose but he didn't
            reply yet.
                              Does anyone have a clue?

                          Try adding the follow line after the "begin" line:

                              ids := '{}'::integer;

                          This should make sure the ids is initialized
            as an empty
                     array of
                          integers.

                     Thanks for your help. Maybe you need some other
            facts about my
                     table?
                     The whole script I am excecuting is the following.
            I changed some
                     things, like adding your code and changing the
            table name 'ways' to
                     'cgn_2po_4pgr':

                     create or replace function
            pgr_makeDijkstraMatrix(thetbl text, sqlP
                     text, OUT dmatrix double precision, OUT ids
            integer)

                                         matrixl := array_append(matrixl,
                     dmatrix[i][r.id <http://r.id> <http://r.id>

                                       end loop;

                     raise notice 'r2.id1: %', r2.id1;
                     raise notice 'ids: %', ids;

                 Sorry, I don't have a running version of this so this
            is somewhat
                 guess work.

                               -- ids := ids || r2.id1;
                                 ids := array_cat(ids, r2.id1);

        try changing the line above to:

                               ids := array_cat(ids, array[r2.id1]);

    Hi Steve, thank you. Back in office now but I'll try that later at home.
    I'll let you know and hopefully I get a good result :slight_smile:
    Thanks so much.
    Carsten

                 So comment out the old like and rewrite like this.

                 -Steve

            Thanks for all your help Steve,
            hope, we're getting closer! Look, not it returns this:

                                       are not part of pgRouting.

                                       You need to ask this question to
            Ivan the
                     author of the
                              original
                                       article.

                                   Sorry, Dose was the original author.

                                       You probably need to add some
            debug statements
                     to get a
                              better
                                       understanding of what the code is
            doing. For
                     example in
                                       pgr_makeDijkstraMatrix before the
            statement:

                                       ids := ids || array[r2.id1];

                                   You could try changing this line to:

                                   ids := ids || r2.id1;

                                   and see if that fixes the problem.

                                   -Steve

                                       Add:

                                       raise notice 'r2: %', r2;
                                       raise notice 'r2.id1: %', r2.id1;
                                       raise notice 'ids: %', ids;

                                       This should show you the
            progression of how
                     the array
                              ids is getting
                                       built as it appears to be
            compaining about
                     that in the
                              error
                                       message.

                                       Hope this helps,
                                           -Steve

Thanks Steve,

my version is
PostgreSQL 9.1.11 on i686-pc-linux-gnu, compiled by gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3, 32-bit

I’am running it on a OSGeoLive 7.0

I’ll wait till later or if someone else who wants to try to solve this one I’ll be happy.

Until later

···

I’m busy for the next few days so I will not have time to look at it until later this week.

What version of postgresql are you running?

select * from version();

I would google “postgresql array functions” and read up on these.There is a function that will tell you the dimensions of an array and maybe you need to print out some more notices to figure out what it is expecting.

Maybe someone else on the list wants to take a crack at this.

Thanks,
-Steve

I tried to write to Dose but he didn’t
reply yet.
Does anyone have a clue?

Try adding the follow line after the “begin” line:

ids := ‘{}’::integer;

This should make sure the ids is initialized
as an empty
array of
integers.

Thanks for your help. Maybe you need some other
facts about my
table?
The whole script I am excecuting is the following.
I changed some
things, like adding your code and changing the
table name ‘ways’ to
‘cgn_2po_4pgr’:

create or replace function
pgr_makeDijkstraMatrix(thetbl text, sqlP
text, OUT dmatrix double precision, OUT ids
integer)
as
$body$
declare
sql text;
sql2 text;
r record;
r2 record;
i integer;
j integer;
matrixl double precision;
begin

ids := ‘{}’::integer;
sql:=‘select node, id-1 as id from ‘||thetbl;
for r in execute sql loop
sql2:=‘select id1, array_agg(cost) as
arow from (
SELECT id1, id2, cost
FROM
pgr_kdijkstraCost(’’’||sqlP||‘____’', '||r.node||

‘, (select array_agg(node) from
‘||thetbl||’ where
id>’||r.id <http://r.id> <http://r.id>
<http://r.id>||'), false, false)

) as foo group by id1 order by id1’;
for r2 in execute sql2 loop
matrixl := ‘{}’;
for i in 1…r.id <http://r.id>
<http://r.id> <http://r.id> loop

matrixl := array_append(matrixl,
dmatrix[i][r.id <http://r.id> <http://r.id>
<http://r.id>+1]);

end loop;
matrixl := array_cat(matrixl,
r2.arow);
dmatrix := array_cat(dmatrix,
array[matrixl]);
raise notice ‘r2: %’, r2;
raise notice ‘r2.id1: %’, r2.id1;
raise notice ‘ids: %’, ids;

Sorry, I don’t have a running version of this so this
is somewhat
guess work.

– ids := ids || r2.id1;
ids := array_cat(ids, r2.id1);

try changing the line above to:

ids := array_cat(ids, array[r2.id1]);

Hi Steve, thank you. Back in office now but I’ll try that later at home.
I’ll let you know and hopefully I get a good result :slight_smile:
Thanks so much.
Carsten

So comment out the old like and rewrite like this.

-Steve

You need to ask this question to
Ivan the
author of the
original
article.

Sorry, Dose was the original author.

You probably need to add some
debug statements
to get a
better
understanding of what the code is
doing. For
example in
pgr_makeDijkstraMatrix before the
statement:

ids := ids || array[r2.id1];

You could try changing this line to:

ids := ids || r2.id1;

and see if that fixes the problem.

-Steve

Add:

raise notice ‘r2: %’, r2;
raise notice ‘r2.id1: %’, r2.id1;
raise notice ‘ids: %’, ids;

This should show you the
progression of how
the array
ids is getting
built as it appears to be
compaining about
that in the
error
message.

Hope this helps,
-Steve
