Hello Alexander, Thanks for the explanation. It's something we do not use. I did not think about it. I look forward to your patch.
I pushed these tasks: MDEV-10581 sql_mode=ORACLE: Explicit cursor FOR LOOP MDEV-12098 sql_mode=ORACLE: Implicit cursor FOR loop MDEV-12011 sql_mode=ORACLE: cursor%ROWTYPE in variable declarations MDEV-12133 sql_mode=ORACLE: table%ROWTYPE in variable declarations Please clone the branch again. Git pull will not work, because I recently rebased bb-10.2-compatibility on top of the latest 10.2. When implementing cursor%ROWTYPE, I had your patch in mind and made some refactoring to help us apply MDEV-10598 easier. Please see a comment to MDEV-12011 in "git log". Now the tricky thing (when adding your patch) is to make sure that this work fine: CREATE PROCEDURE p1 AS a INT:=10; CURSOR cur1 IS SELECT a; rec1 cur1%ROWTYPE; CURSOR cur2 IS SELECT rec1.a; rec2 cur2%ROWTYPE; BEGIN OPEN cur2; FETCH cur2 INTO rec2; CLOSE cur2; SELECT rec2.a; END; I.e. a set of intermixed CURSOR and cursor%ROWTYPE variable declarations referencing each other recursively. Thanks.
Regards, Jérôme.

Hello Alexander, I've done this patch for MDEV-10598. Can you review it ?
It seems we'll have to postpone this patch.
I'm currently working on:
MDEV-10598 Variable declarations can go after cursor declarations MDEV-12011 sql_mode=ORACLE: cursor%ROWTYPE in variable declarations So the trick with postponing variable declarations using a temporary list might not work properly after adding MDEV-10598 abd MDEV-12011, the order of cursors and variables is important.
Example:
DECLARE CURSOR cur1 IS SELECT a,b FROM t1; v cur1%ROWTYPE; CURSOR cur2 IS SELECT v.a, v.b FROM DUAL; BEGIN ... END;
So the order of cur1, v and cur2 is important.
I'll let you known when I'm ready with %ROWTYPE tasks.
Thanks!
Regards, Jérôme.
