Hi, I'm trying to populate a column with 10 raised to the power of the values in another column:
v.db.update map=ItaReg column=x qcolumn=10^logx but I get a dbmi protocol error. I've tried using either single or double quotes with no success. If I use a combination of both, i.e. "qcolumn= ' 10^logx ' " it doesn't report any error, but doesn't do the operation either (the column remains unchanged). It works fine for other operations (e.g. 10*logx), though. Is there another way in which I should specify the exponentiation? Thanks, Marcia _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
