# 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.
