Nic:
Color me stupid! I have had a need for exactly this functionality but was using a PreparedStatement to "select * from
function"
This is great news!
Tell ya what, I was just bragging on y'all here at work regarding how quickly and how helpful everyone is!
Well, thanks a lot for this bit of information...I did read the section regarding the ref cursor type, but I didn't put
theTypes.OTHER together with that section. I feel naive and sorta silly...
Thanks again,
Scot

The CVS version of PG implements CallableStatements that can return
multiple rows.
Do it like this:
try
{
CallableStatement proc
= con.prepareCall("{ ? = call someproc (?) }");
proc.registerOutParameter(1, Types.OTHER);
proc.setInt(2, 1);
proc.execute();
ResultSet rs = (ResultSet) proc.getObject(1);
while (rs.next())
{
System.out.println("ha!");
}
con.close();
}
The proc should return a ref cursor type, much like it would in
Oracle. The PL/PGSQL manual explains how to do that.
