Question

I am using this function to filter query results that are older than 60 days:

s.timeSubmitted >= ( CURDATE() - INTERVAL 60 DAY )

The problem is, the “60 days” part doesn’t seem to be an exact figure. I want it to filter right where s.timeSubmitted is longer than 60 days, down to the exact second of s.timeSubmitted.

How do I write “60 Days” as an exact figure (down to the second)?

Answer 1

The problem is that CURDATE() returns a DATE type, not a DATETIME type (an instant in time). The result of subtracting an interval from a DATE is also a DATE.
Instead, try this:

s.timeSubmitted >= ( NOW() - INTERVAL 60 DAY )

This gives you what you want, because NOW() returns a DATETIME, so the result of the subtraction is also a DATETIME.
