#                                                                              #
# Purpose:                                                                     #
#   Read table t1 row by row                                                   #
#   This routine is only useful for the partition_<feature>_<engine> tests.    #
#                                                                              #
# Note: If this routine is successful, at least the following is fullfilled    #
#       - select single row via $col_to_check basically works -- no crash      #
#       - the table contains all expected rows                                 #
#                                                                              #
