Need advice from a MySQL pro

This should be an easy project for a pro at MySQL.

I need to get an answer to this question today.

In your bid response, please elaborate on what specific help you can provide; bids that are just bids without any supporting explanations will be ignored.

I am having a few problems with an application I am developing using PHP/MySQL. Most of the problems have to do with getting the MySQL code correct.

IMPORTANT: I am using MySQL version [url removed, login to view], so your answers must conform to the abilities of that version and not any subsequent or previous version. Again, this is very, very important.

Specifically:

1) Timestamp field randomly updating to the current date and time after an UPDATE to the table without explicitly setting the timestamp field in the UPDATE as well. Current workaround is to explicitly set the timestamp field on the UPDATE.

2) Doing an UPDATE with a COUNT of a value from another table. I've tried both the transact-SQL method and the MySQL method. The MySQL method seemed to get closer with no syntax errors, except it would always error with "Invalid use of group function". Here's the syntax used:

UPDATE table1, table2

SET table1.value=COUNT([url removed, login to view])

WHERE table1.value2=20 AND table1.value3=[url removed, login to view]

And I've tried this syntax as well:

UPDATE table1 LEFT JOIN table2 ON table1.value3=[url removed, login to view]

SET table1.value=COUNT([url removed, login to view])

WHERE table1.value2=20

3) The other main disadvantage with the current MySQL versions other than a lack of stored procedure support, is the lack of support for sub-queries. This is coming in version 4.1 and will make the creation and implementation of SQL queries a lot easier, reducing 4-8 queries into 1. But for now, I need to figure out how to best use the version I am on.

Thanks.

Marc
