I have a need to let the user pick up to 4 optional sets of columns (a required set will always be included) to be included when a query is run. This means 16 different combination of columns. Instead of having to specify 16 different statements like rows=db.select(sql). (col1,col2,...,coly,colz) statements, I want to build the set of columns to be retrieved first and then have just 1 statement like rows=db.select(sql)(???). But what is the ??? syntax? Thanks, Dave
