Using pltcl... I just strip the comma, if it's there, when I'm all done with the " col = 'value' " bit. string trimright $sql {,} We all have our cheap hacks to bear.... The built-in [quote $value] in pltcl is handy for fending off injection attacks. >>> Martijn van Oosterhout <kleptog@svana.org> 12/09/02 02:51AM >>> On Sat, Dec 07, 2002 at 02:32:48PM -0500, MT wrote: > Hi, > > I'm developing a C++ script to update postgresql database records.

Then i finish it off with a "id=id WHERE ...". That clause becomes a noop and the syntax is fine. Oh yeah, check out the SQL injection attacks.
