I dont seem to find a way to write the output from a previous step in the flow into a SQL table, using the SQL recipes. When I read the documentation, it seems both types of SQL action can only take as an input a SQL dataset? This cant be write, as you would imagine you would want to create datasets in the flow and then commit them to a database?

In the docs above, it describes In\Out parameters as needing to be SQL.
