# Purpose:                                                                     #
#   Do some basic usability checks on table t1.                                #
#   This routine is only useful for the partition_<feature>_<engine> tests.    #
#                                                                              #
# Some Notes:                                                                  #
#   It is intended that in many testcases (statements) more than one partition #
#   or subpartition is affected.                                               #
#   Without analysis of the partitioning function used during CREATE TABLE     #
#   we cannot be 100% sure that this goal is reached.                          #
#   But statements affecting many rows give a good probability that this       #
#   appears.                                                                   #

#   It is expected that the table to be checked contains at the beginning      #
#   of this script records following the scheme                                #
#       f_int1  f_int2  f_char1  f_char2  f_charbig                            #

#   The table content must be equal to the content of the table t0_template.   #
#   Attention: Please be careful when modiying the data.                       #
#              Records can be deleted or inserted, but the content of the      #
#              records after a test/testsequence should follow this scheme.    #

#   All checks of preceding statements via Select are so written,              #
#   that they deliver a                                                        #
