# BUG#47312: RBR: Disabling key on slave breaks replication:
|
|
# HA_ERR_WRONG_INDEX
|
|
#
|
|
# Description
|
|
# ===========
|
|
#
|
|
# This test case checks whether disabling a key on a slave breaks
|
|
# replication or not.
|
|
#
|
|
# Case #1, shows that while not using ALTER TABLE... DISABLE KEYS and
|
|
# the slave has no key defined while the master has one, replication
|
|
# won't break.

# Case #1: master has key, but slave has not.

# Replication does not break.

# We insert two rows. Both with part of UNIQUE KEY set to null.

# Then we update the last row inserted. On master the correct

|
# row is updated. On the slave the wrong row would be updated
|
|
# because the engine would look it up by the NULL Unique KEY.
|
|
# As a consquence, the wrong row would be updated.
