Hi.
I have a table that store different items. For each items, I can attach
up to 5 different textual categories.
Those categories are free-text, and different columns can have the same
values (example below).
I am trying to select the count of each of those categories, regardless
of it's positi

Hello.
What was the error? How was it related to the size problem?
What 'SHOW INNODB STATUS' says?

I've got a table (pages) with an order column (pages.iOrder) and and
grouping column (pages.iCategoryID).
The order column is just a SMALLINT UNSIGNED column, that should contain
the values 1-n for each iCategoryID. These are used to order the rows in
each category.
I'm in the process of writi

So I think we all need to admit that using IN clauses with subqueries on
MySQL 4.1.x is evil. Pure evil.
I attached the blog post I made on the subject a while back. (my blog
is offline)
If you KNOW ahead of time that your subquery involves only a few
columns, then just rewriting the query t

If you mean the exact syntax above, I think not... it looks like ROW()
is a function taking two parameters in this case... what does the

While I am on a roll (of sorts) can I ask if the above syntax should be
valid or not?
I have a feeling it should be valid (but isn't - it causes an error).
Is this the correct behaviour?

It is very likely it is. It is even an example in the MySQL manual.

One issue you have to consider is how the data is entered. If the user
selects from a drop down list then this is ok but you need to plan how the
drop down list is compiled. If not then you need to thinks about spelling
errors, language issues etc.

I would have said...
select pk from a inner join b on a.pk = b.pk;
(probably pk was a bad choice for an example column name).
Using the ON syntax instead of the USING syntax makes my problem look even
more silly than it already is, i.e. just say
