Hi Heikki,

Csongor,

in InnoDB, it is better to use

SELECT ... FOR UPDATE

to lock the result set of a SELECT.


Thank you, I think I will go with this one.

A plain SELECT in InnoDB is a consistent, non-locking read that reads a
snapshot of the database at an earlier time. It does not lock anything.

But it does allow a LOCK during a transaction, doesn't it? Or is this practice not recommended?

Regards,
- Csongor
