However, there is a not-so-pretty workaround: create a temporary table within the function body to store the values returne and then access this table outside the function. Ideal solution = Postgres DB link functions. It runs a query on a remote postgres DB and returns the in a dataset in the function.

Joinable to other tables on the local system. Indexes are utilized on the remote system. A solution I would have liked: Create my own db-link equivalent for MySQL. After that, I would like to store this table in a view, in order to use it in outer join with other tables.

The RETURN statement terminates execution of a stored function and returns the value expr to the function caller. There must be at least one RETURN statement in a stored function. There may be more than one if the function has multiple exit points. To create a function , you must have the INSERT privilege for the mysql system schema.
