To be honest, I am not sure what you are asking me, but I will try to
answer. If I don't succeed to your satisfaction, try again.
When you call a stored procedure in some other databases (DB2, SQL Server,
and some others) that return result sets, and one is using a command line
type interface (not a java program), you don't need to specify the OUT
parameters or the result set. You do have to specify the IN parms.
If the stored procedure has an output result set (in these other databases)
then it just displays the results in the output as soon as you call the SP,
in the same manner SQL*Plus does when the "print results" command does
(using my syntax). Obviously, this is primarily for testing purposes using a
command line type processor, and a java program would have specify some way
to handle the result one row at a time in the program.
If you want an example, I will code one up and post it.
