16.4.1.5 Replication of CREATE ... IF NOT EXISTS Statements

MySQL applies these rules when various CREATE ... IF NOT EXISTS statements are replicated:

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 16.4.1.6, “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.
