# 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 inc/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:                                                                   #

# Attention: The routine inc/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                            #
#                                                                              #
