Hi Sandile:
The error is popping up, apparently, because of the strange "-NULL" value. What is -NULL??
Can you display the rainfall raster? Does it look OK (some value everywhere?)

Perhaps run a check on the original rainfall.tif with gdalinfo to see what range of values it is showing? Then do r.info rainfall to show what range the GRASS raster has.

Hi,

Whats wrong with the rainfall data (rainfall.tif) if you get a DBMI-DBF driver error when running v.rast.stats vector=catchments raster=rainfall colprefix=precip?

SQL parser error: syntax error, unexpected NULL_VALUE processing 'NULL'
in statement:
UPDATE catchments SET precip_cf_=-NULL WHERE cat=2
Error in db_execute_immediate()

ERROR: Error while executing: 'UPDATE catchments SET precip_cf_=-NULL WHERE
