Re: JDBCR4 - Stored Procedure Output Parameters

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Hi Kurt,

CallableStatement is the correct input.  You would not want to pass a 
REsultSet, since there may not be a resultset if your output is all done 
through parameters!

So I guess I don't understand your objection to using a 
CallableStatement.  When you call the stored procedure, you're doing 
something like

TheCallableStatement = JDBC_PrepCall(conn: 'call the-procedure')

Just pass TheCallableStatement back to JDBC_getString() and friends. 
Also, don't forget to register your output parameters.  Java is weird 
about that.
