Hi,
I'm new on this list, so a very short intro about me: I'm Andras Barthazi,
a Hungarian web developer. I like MySQL very much, I'm using it since 3.x
versions, so I think I know it very well. But...
So, I started learning, how MySQL 5.0 handles character sets. It is, what

George,
there seem to be two bottlenecks:
1) InnoDB has contention on the buffer pool mutex;
2) the workload is also disk-read-bound.
For 1), we might have an improvement available in the future. We must let
the threads leave the 'wait array' in sync0arr.c without reserving the wait

Hi there,
as mysql docs describe, there is a stop words table by default:
http://dev.mysql.com/doc/refman/5.0/en/fulltext-stopwords.html
Does anybody know how to add a german table ( I guess there is an
equivalent to the engl. one)?
Does this also work with MySQL 4.0.18?
Thank you for any
Hi Merlin,
you can create your own stopword file (one word per line) and activate it
in my.cnf like this:
# The MySQL server
[mysqld]
set-variable= ft_stopword_file=/etc/my.stopwords

Hi Brent,
Wow, it seems like you are going to extremes. To jump from myisam to
heap is a big step. Did you try using InnoDB? It would handle locking
issues much better since it doesn't lock the table. Heap tables can
be pretty dangerous since it's all in memory. If the machine crashes,

You can nest the IF statement, putting another where 'soon' is like
Jasper suggested. Or you can use the CASE WHEN THEN construct if you
have a lot of conditions you need to check for.

I am having a very odd issue with one of my mysql 4.1.14 servers.
Randomly, the server returns permission denied to queries even if
identical queries succeeded within the same connection.
To test the problem, I setup a script that connects to the database, and
issues the same query 50,000 times.

I've got a very strange problem with one of my MySQL servers.
I've got 2 dedicated servers with MySQL 4.0.21, all is fine there.

Sometimes i've got errors like

Mike, you did a wonderful job at analysis (identifying the 6 cases) but I
think a series of visual clues would have made a simpler query more
obvious. Here's how I understand the issue (I am a more visual thinker)
