Hi,
I have a query which works fine for me in my 4.1 environment, but when
moved to the 5.0.18 environment, it fails with the result below:
mysql SELECT r.uid, u.username, u.image_type, count(id) AS antal,
s.timestamp FROM recruits_uid r, users u, users u2 LEFT JOIN sessions s

Ariel,
You can try this:
mysqlselect stri from prueba order by stri+0 desc;

Or just make the column an INT instead of a CHAR, if you want a natural
number order. Sorting is performed differently between characters and
integers - as is obviously shown in the

See the docs for Update at
http://dev.mysql.com/doc/refman/5.0/en/update.html. You cannot refer to
the update table in a subquery.

Well, it says the host.frm file has the wrong information.
Have you tried mysql_fix_permissions? Or starting the server with
--skip-grant-tables? It's possible the table itself is corrupt.
You could also try backing up the data you have and running
mysql_install_db to re-create the hosts file.
mysqldump takes a table or database and dumps it -- current schema,
current data. You won't get alter tables.
What you want is something that will show all the alter statements.
You can run something like this on unix:
tail -f binlog* | grep ALTER alter.sql
and then the alter.sql text file
Why not also put a wildcard for 192.168.% ? That's what we've done.

That's odd. My mysql.sock is chmod 777, which happened automatically.

I also had problems converting latin1 to utf-8. For whatever reason,
accents and stuff did not convert.
The solution was not to convert to utf-8. If you create your tables
with the character set of latin1, you should be fine (that's what we
did).

Sheeri,
Thanks very much for the reply. However, that is not what I'm looking for. I
don't want the

Thank you for your reply, but I'm afraid it doesn't help :(
The new setup we are moving to is utf-8 only (Apache, mysql). Making some of
the data latin1 and some of it utf-8 will complicate things, we want to move
away from different character encodings, which is why we are using unicode in

Robert,
maybe it was waiting on the AUTO-INC lock of the table? InnoDB must lock the
auto-inc counter, otherwise the MySQL replication would not work. That is a
limitation imposed by the MySQL architecture, not by InnoDB. InnoDB itself
never needs table locks.
