# Helper file to perform one insert of a value into a table with
# different types on master and slave.  The file will insert the
# result into the type_conversions table *on the slave* to get a
# summary of failing and succeeding tests.

# Input:
#    $source_type      Type on the master
#    $target_type      Type on the slave
#    $source_value     Value on the master (inserted into the table)
#    $target_value     Value on the slave (expected value in the table
#                      on the slave)
#    $can_convert      True if conversion shall work, false if it
#                      shall generate an error 
#    $engine_type      The storage engine to be used for storing table
#                      on both master and slave
