# ==== Purpose ====
# The purpose of this script is to test that binary logging returns an error
# when its format is incompatible with the statement to be logged and to verify
# the correctness of the error message.
#
# ==== Requirements ====
# For the conditions 1 to 7 listed in the comments section of method
# decide_logging_format() verify that binary logging returns the proper error or
# warning.
#
# R1. When both row-incapable and statement-incapable storage engines are
#     involved then binary logging returns error
#     `ER_BINLOG_ROW_ENGINE_AND_STMT_ENGINE`.
# R2. When binlog_format = ROW and the SQL statement contains a table stored in
#     a engine limited to statement-logging then binary logging returns error
#      `ER_BINLOG_ROW_MODE_AND_STMT_ENGINE`.
# R3. When binlog_format = ROW and a row is injected in a engine limited to
#     statement-logging then binary_log returns error
#     `ER_BINLOG_ROW_INJECTION_AND_STMT_ENGINE`.
# R4. When binlog_format = MIXED, the SQL statement is unsafe and the storage
#     engine is limited to statement-logging then binary logs returns error
#     `ER_BINLOG_UNSAFE_AND_STMT_ENGINE`.
# R5. When binlog_format = STATEMENT and the SQL statement contains a table
#     stored in a engine limited to row-logging then binary log returns error
#     `ER_BINLOG_STMT_MODE_AND_ROW_ENGINE`.
# R6. When binlog_format = STATEMENT and a row is injected then binary logging
#     returns error `ER_BINLOG_ROW_INJECTION_AND_STMT_MODE`.
# R7. When binlog_format = STATEMENT and the SQL statement is unsafe then a
#     warning is returned.
#
# ==== Implementation ====
#
# TC1. Verify that when both row-incapable and statement-incapable storage
# engines are involved in a SQL statement then binary logging returns the
# error `ER_BINLOG_ROW_ENGINE_AND_STMT_ENGINE`.

# TC6. Verify that when binlog_format = MIXED and a multi-unsafe statement is
#      executed in a table stored in a engine limited to statement-logging then
#      binary logging returns the error `ER_BINLOG_UNSAFE_AND_STMT_ENGINE`.

# ------------------------------------------------------------------
# With binlog_format = STATEMENT :
# 1) Try to insert data on table stored in INNODB as row-only.
