#                                                                              #

# 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                            #

#                                                                              #
