@Bijay

I wrote a email management system log which had the following structure:-
ID
TableName
PrimaryKeyName
Action
LogDate
UserID
ClientID

This allows you to ask questions like How many times to user X update table X on whatever date.

Ho do you propose to achieve #5

5. Use a separate logging table or transactions for logs of table updates, deletes etc.

Any recommendation for the database structure for a general table????

nice tips , i’m using PHP for 5 years but didn’t know all your examples !

I was looking for a lowercase query and found somewhere else :

select * FROM hardware WHERE name regexp ‘$name’

REGEXP isn’t case sensitive. So, problem solved kinda…

Very nice, I wrote a similar article on TalkPHP.com and I was amazed to find that a lot of programmers who used MySQL were blissfully unaware of such statements - like if statements! How can they not know?

Yep performance test everything because it can vary between datasets a lot, I found some things a lot faster than others but you might not get the same results based on your data so keep that in mind. I’m glad the blog helped

Yeah, I did sub-queries a lot in a previous job which is why it just occurred to me, since (1,2,3) is really just like a result set of a sub-query. I actually just did a performance test with a different site I’m working on and found little difference in load times. I’ll have to do more testing (preferably with more concurrent users).

Thanks for all the tips. Of course, I should and will performance test all of the advice, but it’s nice knowing things you didn’t before.
