Hello,

I'm trying to get the difference (in days) between dates stored in two date fields.
My query:


SELECT id,(firstdate- postdate) AS diff FROM calendar

This works fine if the two dates are in the same month, but not otherwise. MySQL appears to be treating the two dates as base-10 integers rather than dates. E.g.:

2004-01-07 (20,040,107) - 2003-12-31 (20,031,231) = 8876

How do I get MySQL to treat these date fields as date fields in this case?


Thanks,


Kenneth
