MySQL is a tradition Relational DataBase System. It underlays
something like 80% (somebody correct me if I'm out-of-date here) of
the http applications populating the internet. While some RDBMSs
offer extensions for RESP-like HTTP implementations, MySQL does not
support this directly. It can be

I've heard that sub-queries aren't well-optimized, but this case seems
ridiculous.
First, a little setup:
SELECT pub_id FROM pub WHERE pub_code = 'GD' INTO @P;

MySQL doesn't support dynamic distribution of data among partitions. The usual
method is to create a partition for each fixed chunk of time, such as for each
month/week/hour/day or whatever time slice breaks your data up in the
manageable pieces. Note that a very large number of partitions (

Yes, it has no indexes so it isn't good for very large subqueries.
You should create them as temporary tables instead and give them
indexes.

Depending on your mysql version and environment, another solution might be
to switch to row-based binlogs. Make sure to read the documentation
thoroughly, though - there's a number of caveats.

Just a note from a kibitzer: if you include an EXPLAIN, why not use \G so that
it is easier to read?

Thank you for the response...
My question now is, will I be able to set the innodb buffer pool size for
the slave server to be the same as the master server?
If so, can I only restart the slave server and keep the master server
running in order to cancel out the requirement for downtime?

Hi All
Just one other note on this issue experienced.
I used google to try and find some solutions / clues and all the
suggestions are to increase the innodb buffer pool size.
This was however recently done on the database to increase this to
4Gb already.
