For example i’ve this query:
SELECT admin_nome FROM ctalk_admin WHERE admin_lastping <= '1233762658' AND
admin_lastping >= '1233762608' AND admin_id='1'
I ran explain, the result for extra is ‘Impossible WHERE noticed after
reading const table...’
Well this one is impossible.
Find records with ping before '1233762658' AND
find records with ping after '1233762608'
The before time is before the after time.
