Hi Sanja, Sergei,


Sanja, you asked me to review a patch for MDEV-10035:

revision-id: 4ffe2295e78538dde93df078421726f0c5a7d2a2 (mariadb-10.2.0-29-g4ffe229)

I earlier also proposed the same idea to disallow FOR UPDATE,
and even created a patch disallowing this in the parser
syntactically (see attached).


But Sergei worried that we should not do it this way and proposed some other solutions. Please see Sergei's comments in:

MDEV-10063 VIEWs and subqueries with FOR UPDATE


Sergei, are you still in doubts?

Just now this parameter for VIEWs effectively (and silently) ignored. So error IMHO is better.
