Thread: Can someone tell me why this statement is failing?
Can anyone tell me why this SQL statement is not
matching with the row from the table below? I think
I'm going mad!
#####################################

SELECT * FROM t_bell_schedule WHERE calendar_day =
'2004-04-12' AND start_time_minutes >= '1082374200'
AND end_time_minutes <= '1082375100';

Your end time minutes is NULL, comparing NULL to anything (even NULL
itself) yields NULL so you either need to:
SELECT * FROM ... WHERE ... AND (end_time_minutes IS NULL OR
end_time_minutes <= '1082375100');
or
SELECT * FROM ... WHERE ... AND coalsece(end_time_minutes, 0) <=
'1082375100';

Hi..
Your END_TIME_MINUTES condition fails..
1082377320 <= 1082375100
