HI,
I need to do a select query that can do the following:
select * from table where col1 like hex(somestring);
My problem is HOW do I get the % in there???
The Mysql Server is 4.0.4 and the table has a blob field with hex stored in
it
Thanks

If the command STOP SLAVE is issued in the middle of the following type of

I suppose that depends really upon the composition of your database.
Unfortunately, I am far from an expert when it comes to MySQL or
virtually any other database, I just happen to know a little bit about
hardware and some performance related information. All of that is
after trying this it shows mysql as running, but /tmp/mysql.sock as not being created.
i stopped mysql and then started it again, and the same thing happened...still no
mysql.sock? should i just reinstall? what is the best way to go about fixing this
problem? thank you.
