Hi. I hope this is the correct mailing list. I am writing a function to extract data either from a table or a query and output it in xml. I have the logic down, but I cannot work out a few things. 1. How can I read the column headings from the returned data set? I have resorted to writing the same function in tcl in which I can work out how to do this, but what about pgsql? I can't use the system tables for this, since the data may not come from a table. 2. It it possible, either in tcl or pgsql, to have optional function arguments? Thanks, Mark
