sl@0: # collate1-1.* - Single-field ORDER BY with an explicit COLLATE clause.
sl@0: # collate1-2.* - Multi-field ORDER BY with an explicit COLLATE clause.
sl@0: # collate1-3.* - ORDER BY using a default collation type. Also that an 
sl@0: #                explict collate type overrides a default collate type.
sl@0: # collate1-4.* - ORDER BY using a data type.
