    21 # Tests are roughly organised as follows:

    22 #

    23 # collate1-1.* - Single-field ORDER BY with an explicit COLLATE clause.

    24 # collate1-2.* - Multi-field ORDER BY with an explicit COLLATE clause.

    25 # collate1-3.* - ORDER BY using a default collation type. Also that an

    26 #                explict collate type overrides a default collate type.

    27 # collate1-4.* - ORDER BY using a data type.

    28 #

    30 #

    31 # Collation type 'HEX'. If an argument can be interpreted as a hexadecimal

    32 # number, then it is converted to one before the comparison is performed.

    33 # Numbers are less than other strings. If neither argument is a number,

    34 # [string compare] is used.
