# Test for rowid ordering (and comparison) functions.

# do index_merge select for tables with PK of various types.

#

# The variable

#     $engine_type       -- storage engine to be tested

# has to be set before sourcing this script.

#

# Note: The comments/expections refer to InnoDB.

#       They might be not valid for other storage engines.

# Last update:

# 2006-08-02 ML test refactored

#               old name was t/rowid_order.test

#               main code went into include/rowid_order.inc
