Hi,

I'm not sure how to do this...

I have a database which contains a messages and categories tables.

The categories table has a field which has a count of the number of messages related to it.

Sometimes however I need to deactivate (active = 0) a message, at the moment this doesn't then update the category table... I will implement this is in the end but for the time I would just like to run a script perhaps daily that goes through all the categories, counts up the messages and updates the field.

What the best way of doing this?

Thanks in advance

Chris
