The parameter markers in the parenthesis are for both input and output
parameter (remember that a SP may have more than one output parameter).
It's important to understand the differences between a parameter and a
return value...
If the SP truly has a single output paramater, the "call function_name(?)"
is correct.
If the SP has NO parameters, but has a return value, then the syntax is "? =
call function_name"
Since you stated that the SP has a single output parameter, then the first
syntax above is correct.

Thanks for the reply, I will try your change tomorrow when I get to the
office.
How ever I am kind of confused here because I have seen the syntax that
you are using before on the mailing list.
Nevertheless I thought that '(?)' after the SP is for 'IN' parameters and
not for 'OUT'.
In standard jdbc '? = function_name(?) ' the '?=' describes the OUT param
whereas (?) after the function is for IN params.
Thanks,
