I haven't actually tried left-joining the same tables multiple times in

However, the syntax of your query is definitely wrong. At the very least,
you need the word 'FROM' to designate which tables you are joining. The

If you are running 4.1.x or 5.0.x, you should be able to do this subquery to

primary key for that record.
The problem is that the record id may not be the same as the record max

If it's IDE, probably not. Moving the database to a different

I think that's because those databases render datetime values into their
"seconds from epoch" values (whichever epoch they use) when casting to a
numeric type (I know MS SQL does. I assume the others do, too.) It seems
that MySQL is the oddball on this issue.

Thanks for the detailed explanation which is what I assumed was
happening. Does
it make any sense though? Shouldn't we get some sort of warning for the
implicit cast? I could be wrong but I thought PostgreSQL, Oracle, and SQL

The MyIsam storage engine is a non transactional engine and InnoDb is a
transactional engine. That is the main difference. So I think the MyIsam
engine should be faster.
Try to adjust the "innodb_thread_concurrency" parameter when you have a
lot of users.

Such a problem often occurs when you had MySQL installation before and

Hello.
Replication shouldn't die if one of the participants goes offline.
But unclean shutdowns of the master may cause inconsistencies between the
content of tables and the binary log in master; this can be avoided by
using InnoDB tables and the --innodb-safe-binlog option on the master.
