There are two Tables A and B.
what i want to do is find out all the records where a.id != b.id
Both tables have close to 1 records. so for every a.id it has to
check table b 1 times and that is what is creating problems.
bcos this query takes hell
2 queries with left outer join will do the trick.
select a.id,b.id from a left outer join b on a.id = b.id where b.id is NULL;
this will give a list over all fields that exist in table a but not in table
b
select a.id,b.id from b left outer join a on a.id = b.id where a.id is NULL;

What you're asking about is the timestamp data type.
Look at : http://www.mysql.com/doc/D/A/DATETIME.html
In a nutshell, if you assign 'null' to a timestamp column it will put in
