Hello Veronica,
Thanks for your answer. Here is my version, under Ubuntu 16.4:
$ g.version -b

According to g.mapset -l, the mapsets are in the search path. If I
make the mapset current, I can access the STRDS in that mapset, but
not from another mapset. I have one temporal DB for each mapset.
Below are the commands:
$ g.mapset -p
hull
$ g.mapset -l
PERMANENT hull_rain hull
$ t.rast.list radar_rain_5min@hull_rain
ERROR: Unable to execute sql statement. There is no temporal database
connection defined for mapset <hull_rain>
$ g.mapset mapset=hull_rain
$ g.mapset -p
hull_rain
$ t.rast.list radar_rain_5min@hull_rain
name|mapset|start_time|end_time
radar_rain_5min_0000|hull_rain|2007-06-24 00:00:00|None
radar_rain_5min_0001|hull_rain|2007-06-24 00:05:00|None
[...]
radar_rain_5min_0575|hull_rain|2007-06-25 23:55:00|None
$ t.connect -p

Thanks again for your help.
Cheers,

Hello Laurent,
AFAIK, you can access STRDS stored in other mapsets as long as those mapsets
are in the search path (check with g.mapsets -p). If I'm in a certain mapset
and I do:
t.rast.list some_strds@other_mapset
it lists the maps as expected... However, the error I get if I try to list
maps in a STRDS that is in a mapset not in the search path, is different
from yours. I get the following:
ERROR: Unable to execute sql statement. You have no permission to access
mapset <rrs_667>, or mapset <rrs_667> has no temporal database. Accessable
mapsets are: <clorofila,pruebas>
The error you get in both cases appears to be related to the database
connection. I guess you run t.connect in those mapsets, right? What is the
output of t.connect -p??
IIUC, the ticket you mention #2110 [0] is related to registering maps from
one mapset in a STRDS of some other mapset, that is not allowed unless you
change the database connection of each mapset to point to a single one (See
Soeren's explanation in ML:
https://lists.osgeo.org/pipermail/grass-user/2016-April/074079.html).
However, I don't think that's what you need, since, again IIUC, you would
only need to access those STDRS in different mapsets but you would NOT need
to register those same maps in a different STDRS in a different mapset,
would you?
Also, what version of grass you use and under which system? (here, i have
freshly compiled grass73 in Linux)
HTH,
Vero

Hello all,
I have several STRDS of rainfall covering a whole country, in a
specific mapset dedicated to rainfall data.
I'd like to run some hydraulic simulations in different regions of the
country, that output several STRDS as results.
For the sake of organizing the data, every study area has its own mapset.
The hydraulic model calls the STRDS from the other mapset return an error:

grass.exceptions.FatalError: Unable to execute sql statement. There is

I realize that if I try to open a strds from another mapset with
t.rst.list, I get a similar error:
ERROR: Unable to execute sql statement. There is no temporal database
connection defined for mapset
Searching for an open ticket about it, I encounter #2110 which seems
related, but it's quite old and it seems in the discussion that a
STRDS should behave like a map, which could be open from another
mapset.
Is it a normal behaviour, and if it's the case, what is the workaround?
Cheers,
Laurent
