Right. I've switched the date column from type INT to type DATE in our MySql db.
The problem I've had with retrieving records in a certain date range with: SELECT * FROM table WHERE yourdate BETWEEN 20030201 AND 20030207 is getting the latter part of the expression; i.e. in this case 20030207 to be seven days "older" than the first part. This is where I need to use MySql's DATE_ADD, and other date manipulation functions.......... Lots to learn; little time to do it.
