The correct result is the data in the updated column after commit.
For example, if I have:
Table1
=
- id
- name
INSERT INTO Table1 (id, name) VALUES (1, 'AAA')
UPDATE LOW PRIORITY Table1
SET name = 'BBB'
SELECT name
FROM Table1
Will it return BBB?
Thanks,

From TFM, If you specify the LOW_PRIORITY keyword, execution of the
UPDATE is delayed until no other clients are reading from the table.
You can get more by RTFM at
http://dev.mysql.com/doc/mysql/en/UPDATE.html
If you specify the LOW_PRIORITY keyword, execution of the UPDATE is delayed until no
other clients are reading from the table.
So, when it returns, all updates will be commited and select statement will return the
correct result.

Yes, I had alread read it, but it only specify when the data
will be commited, not what will be returned.
Let´s change the question:
Before the that
Gleb,
So, when it returns, all updates will be commited and select statement
will return the correct result.
It´s exactly what I´d wanted to know.
Thank you very much,
