Rolls back to a savepoint on the client transaction.

This is a generic implementation. Drivers should override this method to use a method specific for their client connection.

Parameters

string $name: The name of the savepoint.

Return value

bool Returns TRUE on success or FALSE on failure.

Overrides TransactionManagerBase::rollbackClientSavepoint

File

core/modules/mysqli/src/Driver/Database/mysqli/TransactionManager.php, line 32

Class

TransactionManager

MySqli implementation of TransactionManagerInterface.

Namespace

Drupal\mysqli\Driver\Database\mysqli

Code

protected function rollbackClientSavepoint(string $name) : bool {
  // Mysqli does not have a rollback_to_savepoint method, and it does not
  // allow a prepared statement for 'ROLLBACK TO SAVEPOINT', so we need to
  // fallback to querying on the client connection directly.
  try {
    return (bool) $this->connection
      ->getClientConnection()
      ->query('ROLLBACK TO SAVEPOINT ' . $name);
  } catch (\mysqli_sql_exception) {
    // If the rollback failed, most likely the savepoint was not there
    // because the transaction is no longer active. In this case we void the
    // transaction stack.
    $this->voidClientTransaction();
    return TRUE;
  }
}
