# Tests are roughly organised as follows:
#
# collate1-1.* - Single-field ORDER BY with an explicit COLLATE clause.
# collate1-2.* - Multi-field ORDER BY with an explicit COLLATE clause.
# collate1-3.* - ORDER BY using a default collation type. Also that an
# explict collate type overrides a default collate type.
# collate1-4.* - ORDER BY using a data type.
#
#
# Collation type 'HEX'. If an argument can be interpreted as a hexadecimal
# number, then it is converted to one before the comparison is performed.
# Numbers are less than other strings. If neither argument is a number,
# [string compare] is used.
