Interface Yiisoft\Db\Migration\TransactionalMigrationInterface

Defined in: Yiisoft\Db\Migration\MigrationInterface::up()

This method contains the logic to be executed when applying this migration.

The DB logic implemented here will be enclosed within a DB transaction.

Child classes may implement this method instead of {@see \Yiisoft\Db\Migration\up()} if the DB logic needs to be within a transaction.

Note: Not all DBMS support transactions. And some DB queries cannot be put into a transaction. For some examples, please refer to implicit commit.
