Hi,
What you could try is pass two parameters to your group_bconcat aggregate
function, the first one the value and the second the sort value. That way
the function can sort itself (which is what group_concat does as well).
That would look as follows: select group_bconcat(binData, orderColumn) fro
Here's the query with standard group_concat and cast:
SELECT CAST(GROUP_CONCAT(`expScores` ORDER BY `i` SEPARATOR '') AS BINARY)
AS `expScores` FROM `probes` LEFT JOIN `joins` ON `probes`.`id` = `pid`
LEFT JOIN `scores` ON `sid` = `scores`.`id` WHERE (`probes`.`eid` =
(SELECT id FROM `experime
