# ANNOTATE\_ROWS\_EVENT `ANNOTATE_ROWS_EVENT` events accompany row events and describe the query which caused the row event. You can enable this with [--binlog-annotate-row-events](https://mariadb.com/docs/server/ha-and-performance/standard-replication/replication-and-binary-log-system-variables) (default on). In the binary log, each `ANNOTATE_ROWS` event precedes the corresponding Table map event. For additional information refer to the [annotate\_rows\_log\_event](https://mariadb.com/docs/server/clients-and-utilities/logging-tools/mariadb-binlog/annotate_rows_log_event) documentation. {% hint style="info" %} The master server sends `ANNOTATE_ROWS_EVENT` events only if the replica server connects with the `BINLOG_SEND_ANNOTATE_ROWS_EVENT` flag (value is 2) in the `COM_BINLOG_DUMP` replica registration phase. {% endhint %} ## Header * Event Type is 160 (`0xa0`). ## Fields * [string\](https://mariadb.com/docs/server/reference/protocol-data-types#fixed-length-bytes) The SQL statement (not null-terminated). ## Complete Example with CRC32 ``` ee b7 15 5a a0 01 00 00 00 36 00 00 00 80 0b 00 ...Z.....6...... 00 00 00 69 6e 73 65 72 74 20 69 6e 74 6f 20 74 ...insert into t 65 73 74 2e 74 34 20 76 61 6c 75 65 73 28 31 30 est.t4 values(10 30 29 6d 4c 42 33 0)mLB3 ``` *This page is licensed: CC BY-SA / Gnu FDL* {% @marketo/form formId="4316" %}
