Name

SQL-02: Don't leave transactions "dangling"

Synopsis

Once you start a transaction, you should take responsibility for completing the transaction. Since transactions lock rows and potentially block other transactions, you need to ensure that transactions do not persist indefinitely. Generally, you should place the START TRANSACTION and COMMIT or ROLLBACK statements in the same stored program. This program may also call other programs, and you need to make sure that these called programs do not contain transactional code.

There are some exceptions to this recommendation. In particular, modular design might prompt you to break down a transaction into separate modules and control the overall transaction state from a master procedure.
