CR-XI using MySQL: group by not working for timestamp

[smzafar]

I am trying to get the max(timestamp) and min(timestamp) for every grouped data but it is only showing the max and min for the whole table. The following SQL works fine in PHPMyAdmin using MySQL, however I need to get the same results using CR-XI.

MySQL:

select file_id, max(timestamp), min(timestamp) 
from 360_status_log 
group by file_id 
order by file_id

In the Select Expert open the Group Selection Formula Editor and enter:
{Table.TimeStamp} = Maximum({Table.TimeStamp},{Table.File_Id})
or
{Table.TimeStamp} = Minimum({Table.TimeStamp},{Table.File_Id})

Note that the Group Selection only suppresses records that do not meet the group selection criteria. The suppressed records will still be used if you Insert > Summary data, in which case you would want to use running totals.
