# BUG#50479 DDL stmt on row-only/stmt-only tables generate spurious
#           binlog_format errors
#
# In the fix of BUG#39934 in 5.1-rep+3, errors are generated when
# binlog_format=row and a statement modifies a table restricted to
# statement-logging (ER_BINLOG_ROW_MODE_AND_STMT_ENGINE); or if
# binlog_format=statement and a statement modifies a table limited to
# row-logging (ER_BINLOG_STMT_MODE_AND_ROW_ENGINE).
#
# In this test case, we check if some DDL statements that lock tables do not
# trigger errors as they do not generate rows events and as such are harmless
# from the point of view of conflicts between the engine's supported logging
# format and the value of binlog_format.
#
# In particular, we check if:
#   1 - ALTER TABLE, CREATE INDEX and CREATE TRIGGER do not generate either
#   ER_BINLOG_STMT_MODE_AND_ROW_ENGINE or ER_BINLOG_STMT_MODE_AND_ROW_ENGINE
#
#   2 - CREATE TABLE ... SELECT generates an error because the command can
#   generate row events but CREATE TABLE without SELECT does not generate
#   an error.
