MySQL 5.7 Release Notes
BINLOG 'str'
BINLOG is an internal-use
statement. It is generated by the mysqlbinlog
program as the printable representation of certain events in
binary log files. (See Section 4.6.7, “mysqlbinlog — Utility for Processing Binary Log Files”.) The
' value is a
base 64-encoded string the that server decodes to determine the
data change indicated by the corresponding event. This statement
requires the str'SUPER privilege.
This statement can execute only format description events and row events.
