Re: returning rows from a function

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,
