# This one assumes we are ignoring updates on tables in database mysqltest2,
# but doing the ones in database mysqltest
#################################################################
# Change Author: JBM
# Change Date: 2006-02-02
# Change: Added ENGINE=MyISAM
# Reason: LOAD from master is only supported by MyISAM

# "mysqltest". This "drop" is a bug; in that case t3 would disappear.  So
# here the effect of this bug (BUG#1248) would be to leave an empty
# "mysqltest" on the slave.
