This is going to do a textual comparison, not an integer one.
So it's looking for jobnumbers greater than the string '999'.
If you want to treat jobnumber as an integer, CAST(jobnumber as integer)
>= 999 may be what you want. Note, however that it will fail if there are
any non-numeric jobnumber rows. In general, storing numbers in strings
that you want to act upon as numbers is a bad idea.
