SQL Script Syntax

  • Standard SQL syntax with statement delimiter ;
  • Delimiter change for stored procedures using DELIMITER statements
  • Comment directives generated by mysqldump (/!…/;)
  • MySQL-style single-line comments (# Comment)

Compatibility

  • DDL exported by mysqldump can be used unchanged in a Flyway migration.
  • Any MySQL SQL script executed by Flyway, can be executed by the MySQL command-line tool and other MySQL-compatible tools (after the placeholders have been replaced).

Example

/* Single line comment */
CREATE TABLE test_data (
 value VARCHAR(25) NOT NULL,
 PRIMARY KEY(value)
);

/*
Multi-line
comment
*/

-- MySQL procedure
DELIMITER //
CREATE PROCEDURE AddData()
 BEGIN
   # MySQL-style single line comment
   INSERT INTO test_data (value) VALUES ('Hello');
 END //
DELIMITER;

CALL AddData();

-- MySQL comments directives generated by mysqlsump
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;

-- Placeholder
INSERT INTO ${tableName} (name) VALUES ('Mr. T');

Limitations

  • Issue 558 The parser currently doesn’t support multiple comment directives on a single line.
    Example: /!50003 CREATE/ /!50017 DEFINER=.../ /*!50003 TRIGGER EntityBeforeInsert …
