Hi,
I think you should try to use 0 instead of NULL

Hi.
Could you run the following query:
SELECTIF(call_end - call_start 5, id, NULL) AS long,
IF(call_end - call_start = 5, id, NULL) AS short,
COUNT(*)
FROM t_calllog_calls
GROUP BY long, short
Given that I have not made any mistake, that should list all rows
18 matches
