From the MySQL documentation:
* A PRIMARY KEY is a unique KEY where all key columns must be defined
as NOT NULL.
KEY is a synonym for INDEX. So, specifying PRIMARY KEY implies UNIQUE and
INDEX.. You don't have to specify them yourself.

As I discovered recently, thanks to another user on this list, there is at
least one situation where you WILL need to also create a KEY index on a

If you have a composite primary key such as (col1, col2) and you wish to
place a foreign key on col2, you will ALSO have to add a

Yep. Theres no reason at all why this sort of thing won't work for MSSQL
too. Use SQL Enterprise Manager to generate a create script for all objects
in the database, and also tell it to script referential integrity (FKs,
etc).
Then add anything MySQL specific, such as Type=InnoDB (which you will

Not sure why you are checking for a NULL ordered in orderitems? That would
suggest you get back only items

Hi folks.
I've just submitted the following as a 'bug' via the MySQL website, and was
wondering if anyone out there had experienced the same problem?
It only seems to cause a crash when a nested IF is put into a stored

than 2, however, if that

I have a query where I get an average of weekly miles.
For example:
Average Weekly Miles:
3.4285714285714
How would I get this number into a more read format? Such as 3.42. I
have tried the truncate but I can't seem to get it to work. Does any
one have any suggestions?

I think your looking for the ROUND(N,D) function, IE:
select round('3.4285714285714',2) as miles;
3.43 miles

I understand that MySQL Replication can be configured
to replicate selected tables in a Database. Is there
anyway to further constrain the replicate, say based
on a query of these tables etc..?

Steven,
In your case, you query doesn't even use an index. And you are using an
order by DESC. Now what I would recommend is something like this, change
your query just to test this out.
SELECT p.* FROM p_cat c, p_ad p WHERE p.cat = c.id AND c.lft
BETWEEN 4 AND 5 ORDER BY p.date DESC LIMIT
