SQLite

Supported Versions

• 3.7 and later 3.x versions

Support Level

Support Level determines the degree of support available for this database (learn more).

Drivers

SQL Script Syntax

• Standard SQL syntax with statement delimiter ;
• Triggers with BEGIN ... END; block

Compatibility

• DDL exported by SQLite can be used unchanged in a Flyway migration
• Any SQLite SQL script executed by Flyway, can be executed by the SQLite tools (after the placeholders have been replaced)

Example

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

/*
Multi-line
comment
*/

-- Sql-style comment

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

CREATE TRIGGER update_customer_address UPDATE OF address ON customers
  BEGIN
    UPDATE orders SET address = new.address WHERE customer_name = old.name;
  END;

Limitations

• No concurrent migration as SQLite does not support SELECT ... FOR UPDATE locking
• No support for multiple schemas or changing the current schema, as SQLite doesn’t support schemas
• No support for CREATE TRANSACTION and COMMIT statements within a migration, as SQLite doesn’t support nested transactions
