[Maria-developers] Patch for MDEV-12874 - UPDATE statements with the same source and target

Hello, Here is a patch for MDEV-12874 (on branch 10.2-ext). Can anyone review it ? Alexander, during my work on this MDEV, I've found a new issue with update statement and Oracle compatibility. create table t1 (c1 integer, c2 integer, c3 integer); insert into t1(c1,c2,c3) values (1,1,1); update t1 set c1 = c1+1, c2 = c1+1, c3 = c2+1; select * from t1; Mariadb : +------+------+------+ | c1 | c2 | c3 | +------+------+------+ | 2 | 3 | 4 | +------+------+------+ 1 row in set (0.00 sec) Oracle : DVTORA> C1 C2 C3 ---------- ---------- ---------- 2 2 2 Can you open a new MDEV for this ? Best regards, Jérôme.
