Since the "RETURNING INTO" clause requires special analysis of the statement executed, its translation is planned to be delivered in the future.

Transformation for the following line correspond to collection types which is work in progress:

Also the following EXECUTE IMMEDIATE related with the BULK COLLECT into the sals variable, is also work in progress.
