andy you dont say if you just want a query to do this or an update (answers so far have been update based.. which is ok if you have a column ready to fill..if noy then you have teh hassle of altering teh table structure etc etc..
I tend to do this kinda stuff as a query so setup the QL form with the followiing psuedo sql: select col1,col2 col1 * col2 "MyRESULT" from mytab into MYanswers this will return three columns, the two cols of source dat and their product flagged as MyResult in a table called myanswers you can also use teh column picker tool in a browse window to do teh same..when you pick a field to view there is an option to perform an 'expression' build teh expression et voila your browser now contains an extra column of info. r -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Andrew Tracey Sent: 28 November 2005 17:19 To: MapInfo-L@lists.directionsmag.com Subject: [MI-L] SQL Select Dear All This may be a easy one but hear goes, I have two columns of data which I want to multiply the values of each together and give the result in a additional column.
