Gnerally the intent is to be as compatible with Oracle as possible when running with sql_mode=ORACLE. So we should definitely implement this eventually. I have created these sub-tasks under "MDEV-10764 PL/SQL parser - Phase 2": MDEV-12032 sql_mode=ORACLE: recursive stored functions MDEV-12033 sql_mode=ORACLE: transactions in stored functions MDEV-12034 Dynamic SQL in stored functions But I can't give a precise time frame estimation when we'll be able to work on this. Currently we're working on MDEV-10142 and its sub-tasks. There are still 15 out of 42 sub-tasks to be done. But some subtasks will probably move from MDEV-10142 (phase#1) to MDEV-10764 (phase#2). > > Have you planned to remove these limits? > > If not, we'll have to find the best workarounds to use stored procedures (and > find a solution to mimic a return code) Right, workarounds with wrapping a procedure into a function are possible. For example, I found this page: http://ethellenterprises.com/2011/05/recursive-stored-functions-in-mysql/ > > Best regards, > Jérôme. > > _______________________________________________ Mailing list: https://launchpad.net/~maria-developers Post to : maria-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~maria-developers More help : https://help.launchpad.net/ListHelp
