Nikheel, It can done indirectly by returning a refcursor. I sent out the attached java program last week on the pgsql-jdbc mail list last week showing how refcursors can be used to return records. While recursors are intended to return the results of a query, you can also use them to return arbitrary sets of records as well, as the example shows. It is ugly but can be done. thanks, --Barry Nikheel Dhekne wrote: > I am new to Postgres and have a rather straightforward question.
