# inc/partition_alter_11.inc #
# #
# Purpose: #
# Check ALTER partitioned table and the state of the table afterwards #
# The partitioning function use the column f_int1 #
# #
# For all partitioning methods #
# PARTITION BY HASH/KEY/LIST/RANGE #
# PARTITION BY RANGE/LIST ... SUBPARTITION BY HASH/KEY ... #
# do #
# 1. Create the partitioned table #
# 2. Execute inc/partition_alter_1.inc, which will #
# - Insert the first half of the table t0_template into t1 #
# - Execute the ALTER TABLE statement #
# - Insert the second half of the table t0_template into t1 #
# - Execute the usability test include/partition_check.inc #
# - Drop the table t1 #
# done #
# #
# The parameters #
# $unique -- PRIMARY KEY or UNIQUE INDEXes to be created within the #
# CREATE TABLE STATEMENT #
# $alter -- ALTER TABLE statement, which has to be executed #
# have to be set before sourcing this routine. #
# Example: #
# let $unique= , UNIQUE INDEX uidx1 (f_int1); #
# let $alter= ALTER TABLE t1 DROP UNIQUE INDEX uidx1; #
# inc/partition_alter1.inc #
# #
# Attention: The routine include/partition_alter_13.inc is very similar #
# to this one. So if something has to be changed here it #
# might be necessary to do it also there #
