transaction<T> abstract method

Future<T> transaction<T>(
  1. FutureOr<T> f(
    1. QueryExecutor
    )
)

Enters a database transaction, performing the actions within, and returning the results of f.

If f fails, the transaction will be rolled back, and the responsible exception will be re-thrown.

Whether nested transactions are supported depends on the underlying driver.

Implementation

Future<T> transaction<T>(FutureOr<T> Function(QueryExecutor) f);
