Hi!! I have a CGI that looks up data from a mysql data base and does a bunch of calculations. I only want to do calculations on the columns which contains any data. What I mean is for some colums there is no data available at all. So I don't want to do any calculations on them obviously. How do I check whether the column contains data, once I have retrived all the data using fetchrow_hashref(). Thanks and Cheers alway!! Murli
