# BUG#20141
|
|
# The following tests ensure that if user-defined variables are used in SF/Triggers
|
|
# that they are replicated correctly. These tests should be run in both SBR and RBR
|
|
# modes.
|
|
|
|
# This test uses a procedure that inserts data values based on the value of a
|
|
# user-defined variable. It also has a trigger that inserts data based on the
|
|
# same variable. Successful test runs show that the @var is replicated
|
|
# properly and that the procedure and trigger insert the correct data on the
|
|
# slave.
|
|
#
|
|
# The test of stored procedure was included for completeness. Replication of stored
|
|
# procedures was not directly affected by BUG#20141.
