Dan,
I do need to prevent writes from occurring between the DROP and CREATE.
The primary purpose of this is to prevent the CREATE from failing due to
duplicate entries being found during key creation.
As CREATE INDEX has no IGNORE option, I had thought I would have to do this a
nasty way, but
What you are asking for is exactly what DEFINER security does. The
applicxation owner grants appuser the right to execute the procedure,
but not to SELECT from any tables. The procedure is then run with the
security attributes of the definer of the procedure, the application
owner, even though
You can only specify one IP address to bind to.
If you omit this option, mysqld will bind to all addresses on the
machine. If this is not what you want, you could block mysql-access with
a packet filter for the IP addresses you do not want to bind to.

Hi,
I'm including your post to the forum as well.
The problem I think is the fact that you need to
do LEFT JOIN in two directions which quite often
don't turn out what you want.
So what you can do is to do two queries, UNION
them together and form a derived table that you
then do your final

Hi,
Is there a tool available which can be used to transfer (periodically)
between a MSSQL server and that of a MySQL Server?
Is there anyone here who does this periodically? Either through a tool
or via a command line script or something?
Would appreciate any feedback or suggestions.
Thanks
Anyone here know enough about how the optimizer works to explain why it is use
the less optimal index in this case?

This does the opposite of what I want. Is there some way to tell it

Robert, I can't remember which version you said you were on, but the
last few updates to the 5.0.x series have fixed some optimizer bugs.
You might check the functionality in the latest release (5.0.25).
See http://dev.mysql.com/doc/refman/5.0/en/news-5-0-x.html
for the list of 5.0 changes.

You can add an offset in the Limit statement. Look at the Select Syntax in
the docs.
There is an even simpler solution to this problem. Use your creation field
within a Where clause instead of using Order by and Limit.

Brian, assuming you have an identity column of some kind (we'll call
it id here), this should work:
CREATE TABLE tmptable (id INT NOT NULL AUTO_INCREMENT PRIMARY KEY);
INSERT INTO tmptable (id) SELECT id FROM tablename ORDER BY creation
DESC LIMIT 1;
DELETE FROM tablename
WHERE id NOT IN

The offset is what I was thinking of - that would be the simplest -
but as far as I can tell, delete doesn't support the offset. It's not
documented, and it gives me an error when I try it. I was hoping to
avoid two queries but it sounds like that's what I might have to do.

DELETE does support the offset
(http://dev.mysql.com/doc/refman/5.0/en/delete.html) the problem is you have an
erroneous equals character:

My bad, the = was my own typo just in the email, it's not in my
actual query. I've tried using offset (delete...limit 50,99) and
it returns an error, and it is not documented (search that page you
referenced for offset).

Brian,
My bad in steering you into the offset direction. You are right. Offset
cannot be used within a delete statement. However, if I am reading your
email correctly, you could specify a cutoff date and use that in the Delete
statement like this:
DELETE FROM tablename WHERE creation
