then i try to use:
d.rast.pg -s sql=f input=rd_map output=new_map
with f:
retrieve unique (color_map002.sect_id,
color_map003.sect_id) where color_map003.color="green"
getting the error info. : parse error at or near "retieve".
could anyone tell me how to fix it?
Try using 'select' instead of 'retrieve'.
