I would like to know whether a SELECT query would block an Update on the

Since InnoDB tables apply row level locks should the Update queries be
blocked until the select query completes?
I experienced such a scenario wherein an update query had to wait until the
select query completed.
Also how different is the locking when there is a "CREATE TEMPORARY TABLE
<tblname> AS SELECT * FROM TBL_TEST" and an Update on the table TBL_TEST
simultaneously?

and

might give you some ideas about what's going on.
