We have a cloud hosted instance of Appian using MySQL. I've tried to create an index on a table with one of the keys being descending rather than the default of ascending, but it is not working.

The SQL I'm using is

ALTER TABLE `Demand_Notes`
ADD UNIQUE KEY `IX1_Demand_Notes` (`demandId`,`createdDateTime` desc,`noteId`);

Can someone explain what I'm doing wrong.

Descending index is not supported in MySQL (till 5.7). Keywords may be given, but they are anyways ignored and only ascending index is supported, which is default.
