Hi

When I’m running the command below I’m getting some errors, I pasted them
below
v.rast.stats -ec vector=catchments raster=rainfall colprefix=rain_cols percentile=90

DBMI-DBF driver error: SQL parser error: syntax error, unexpected NULL_VALUE
processing ‘NULL’
in statement: UPDATE catchments SET rain_cols_=-NULL WHERE cat=1
Error in db_execute_immediate
ERROR: Error while executing: ‘UPDATE catchments SET rain_cols_=-NULL WHERE
cat=1’

   Do you really mean '-NULL'? I've never seen NULL negated before.

Hi Sandile
Is there raindata for all the catchments? Do they cover the same region?
i.e. maybe you can post the output of each of these:
g.region -p
v.info -g catchments
r.info -g rainfall
