# Example how to use this auxiliary script
#-----------------------------------------
#
### The table/tables used in $part must have the right content.
### $title_prefix is used for the generation of titles
#
# let $title_prefix= 4.3;
### $check_num is used for the generation of titles and gets incremented after
### every call of the current script.
# let $check_num= 1;
### $diff_column_list is used for the generation of error information and valid for
### every sub test.
# let $diff_column_list=
# t2.COUNT_READ - t1.COUNT_READ AS D_COUNT_READ,
# t2.COUNT_READ AS S2_COUNT_READ,
# t1.COUNT_READ AS S1_COUNT_READ,

# t2.COUNT_MISC - t1.COUNT_MISC AS D_COUNT_MISC,
# t2.COUNT_MISC AS S2_COUNT_MISC,
# t1.COUNT_MISC AS S1_COUNT_MISC;
### $part is used for the generation of "check" statements + error information
### and valid for every sub test.
# let $part=

#
# --echo # $title_prefix Check the differences caused by SQL statement
#
# let stmt1= SELECT col2 FROM does_not_exist;
# let stmt2= SELECT col2 FROM does_not_exist WHERE col1 = 0;
### $msg is used to generate some explanation of what we compare.
# let $msg=
# # One statement is longer than the other.
# # Both statements fail with the same error message (table does not exist);
# let $my_rules=
# t2.COUNT_READ - t1.COUNT_READ = 0 AND
