Create an Action that returns only the first value of this stream of data. The Action will fail if the stream is empty. Only available on streaming Actions.

Create an Action that returns only the first value of this stream of data as an Option. Only available on streaming Actions.

Create an Action that uses the specified SQL statement(s) but otherwise behaves the same as this Action.

Return the SQL statements that will be executed for this Action

A shortcut for andThen.

Run another action after this action, whether it succeeds or fails, and then return the result of the first action. If the first action fails, its failure is propagated, whether the second action fails or succeeds. If the first action succeeds, a failure of the second action is propagated.

Run another action after this action, if it completed successfully, and return the result of the second action. If either of the two actions fails, the resulting action also fails.

Convert a successful result v of this action into a successful result Success(v) and a failure t into a successful result Failure(t). This is the most generic combinator that can be used for error recovery. If possible, use andFinally or cleanUp instead, because those combinators, unlike asTry, support streaming.

Run another action after this action, whether it succeeds or fails, in order to clean up or transform an error produced by this action. The clean-up action is computed from the failure of this action, wrapped in Some, or None if this action succeeded.

Transform the result of a successful execution of this action, if the given partial function is defined at that value, otherwise, the result DBIOAction will fail with a NoSuchElementException.

If this action fails, the resulting action also fails.

Return an action which contains the Throwable with which this action failed as its result. If this action succeeded, the resulting action fails with a NoSuchElementException.

Filter the result of this action with the given predicate. If the predicate matches, the original result is returned, otherwise the resulting action fails with a NoSuchElementException.

Use the result produced by the successful execution of this action to compute and then run the next action in sequence. The resulting action fails if either this action, the computation, or the computed action fails.

Creates a new DBIOAction with one level of nesting flattened, this method is equivalent to flatMap(identity).

Return the name, main info, attribute info and named children

Whether or not this action should be included in log output by default.

Transform the result of a successful execution of this action. If this action fails, the resulting action also fails.

Get a wrapping action which has a name that will be included in log output.

Get the equivalent non-fused action if this action has been fused, otherwise this action is returned.

Use a pinned database session when running this action. If it is composed of multiple database actions, they will all use the same session, even when sequenced with non-database actions. For non-composite or non-database actions, this has no effect.

Run another action after this action, if it completed successfully, and return the result of both actions. If either of the two actions fails, the resulting action also fails.

Run another action after this action, if it completed successfully, and zip the result of both actions with a function f, then create a new DBIOAction holding this result, If either of the two actions fails, the resulting action also fails.
