Обсуждение: jdbc/callable statment error

When executing the following statments from netbeans 4.1 sun app server 8.1

CallableStatement proc = con.prepareCall("{ ? = call test_function ( ? ) }");
proc.registerOutParameter(1, Types.BOOLEAN);
proc.setString(2, "testthis");
proc.execute();

This shows up in my server log.

LOG:  statement: select * from  test_function ( 'thisTest' )  as result;
ERROR:  function test_function("unknown") does not exist
HINT:  No function matches the given name and argument types. You may need to add explicit type casts.


And I get an exception from my app server that states "No function" etc, etc...

Now,  if I cut and paste that into my psql terminal it appears to work... So I'm really curious as to why it doesn't
workthrough jdbc... 

Couple of things:  I'm getting my connection through a connection pool on my app server and that appears to be in
workingorder... 

Any suggestions?

And now that I think of it, I'm useing postgres 7.4

Not sure how relevant that is,

Gary

What do the logs say when you excecute this from psql ?

After experiencing something similar, I read somewhere
that CallableStatement's shouldn't be used pre-8.0. I
think someone posted on a message board or something.

I changed all my java code to call my functions as
PreparedStatements:

ps = con.prepareStatement("select myFunction(?,?)")
ps.setBoolean(1, true);
ps.setInt(2, 198);
etc.

And it worked fine from there on.
