#############################################################################

# Note: Many lines are commented out in this test case. These were used for #

#       creating the test case and debugging and are being left for         #

#       debugging, but they can not be used for the regular testing as the  #

#       Time changes and is not deteministic, so instead we dump both the   #

#       master and slave and diff the dumps. If the dumps differ then the   #

#       test case will fail. To run during diff failuers, comment out the   #

#       diff.                                                               #

# Test: Tests MySQL stored function using RAND() and a flow control. The    #

#       test inserts  rows into a givin table with the function used in     #

#       the insert statement. Depending on the  RAND() value returned       #

#       inside the function one set of text is returned. In addition,       #

#       it uses a transaction to see the effect a rollback has on master    #

#       Vs slave.                                                           #
