function DatabaseConnection_sqlite::popTransaction

Decreases the depth of transaction nesting.

If we pop off the last transaction layer, then we either commit or roll back the transaction as necessary. If no transaction is active, we return because the transaction may have manually been rolled back.

Parameters

$name: The name of the savepoint

Overrides DatabaseConnection::popTransaction
