Hello.
Use:
set autocommit=0;
or begin a transaction before executing 'select ... lock in share mode'.
Commit the tramsaction to release lock.

Hi,
I am trying to learn more about InnoDB to convert MyISAM to InnoDB.
according to MySQL document, I can lock a record like this:
SELECT * FROM mytable WHERE id = '100' LOCK IN SHARE MODE;
I run this query and showed a message to stop the screen (waiting) and on
the other computer I run the same query or even I updated the record (which
is locked by the other computer), but I didn't get any error. How does this
work? Did I miss anything here?
My other question: if I lock a record with that command, then how I can
release the lock? I could find any command to release the lock!
thanks
