Thank you a lot. The first indexing process finished after about 13
hours, so I think the problem is solved now.
I set the myisam_sort_bufffer_size to 10GB.
For the query I will adjust it to your version.

The "first indexing process"???
You should have created all of your indexes with one Alter statement.
Can you PLEASE note in your listing when a product is Microsloth-only?
While you're at it, can you PLEASE note it prominently on your website? I
looked through your product description and saw no specific requirements beyond
what databases were supported. It wasn't until I tried to download it t
Hi,
thanks for the hint, I was testing the settings for the
myisam_sort_buffer_size so I totally forgot it.
But I have another three of these databases to do, so next time I do it
with one ALTER statement

I don't know if new members usually introduce themselves here...
...but if not, why not?
I was very active on the SQL Server news group a few years back but this MYSQL
stuff is new to me.
Seems I'll be muddling around for at least a little while so I might have a few

I'm trying to figure out an elegant way with Mysql 5.5.25 to log changes
via a before change trigger to a table including the column name of the
field that changed...
How can I dynamically enumerate the field names and populate the field log

(
SELECT ruid1, ruid2, overlap FROM l4_link WHERE ruid1=xxx
UNION
SELECT ruid1, ruid2, overlap FROM l4_link WHERE ruid2=xxx
) ORDER BY overlap DESC;
Make it UNION ALL or UNION DISTINCT depending on whether xxx can be in both
fields of one row.

I suspect that the output from each will be identical, and have more parens.
The main need for parens is to avoid associating the ORDER BY with jus
