Thank you for the answer.
I think i tried that too, anyway I tried it again with both components Sqldb and Zeos. After trying that on many stored procedures (some created from the user, some from the system, some with some without parameters), basically in one line encapsulating proc call with begin end, with sqldb a different error is raised now ("ora-06550 line 1 column 12 pls-00103 encountered the symbol [ProcName] when excpecting one of the following: := . ( @ % ;") ; zeos still same ("zero iteration count" - btw I've asked this question in zeos forum too, and post is waiting for approval and I doubt anyone will respond);
So my question is, has anyone in this forum managed to execute an oracle sp successfully from sqldb query component (or zeos)?
If yes, could anyone provide me with an example? And if it's not possible then why it is so?
