Every CREATE DATABASE IF NOT EXISTS statement is replicated, whether or not the database already exists on the source.

Similarly, every CREATE TABLE IF NOT EXISTS statement without a SELECT is replicated, whether or not the table already exists on the source. This includes CREATE TABLE IF NOT EXISTS ... LIKE. Replication of CREATE TABLE IF NOT EXISTS ... SELECT follows somewhat different rules; see Section 19.5.1.7, “Replication of CREATE TABLE ... SELECT Statements”, for more information.

CREATE EVENT IF NOT EXISTS is always replicated, whether or not the event named in the statement already exists on the source.

CREATE USER is written to the binary log only if successful. If the statement includes IF NOT EXISTS, it is considered successful, and is logged as long as at least one user named in the statement is created; in such cases, the statement is logged as written; this includes references to existing users that were not created. See CREATE USER Binary Logging, for more information.

CREATE PROCEDURE IF NOT EXISTS, CREATE FUNCTION IF NOT EXISTS, or CREATE TRIGGER IF NOT EXISTS, if successful, is written in its entirety to the binary log (including the IF NOT EXISTS clause), whether or not the statement raised a warning because the object (procedure, function, or trigger) already existed.
