An external stored procedure that uses CLIv2 to directly execute SQL can call a stored procedure that creates up to 15 dynamic result sets.
To indicate that the external stored procedure is willing to consume result sets created by a stored procedure, the SQL request that contains the CALL statement must set the Dynamic Result Sets Allowed option in the DBCAREA to 'Y'.
Here is a code excerpt for a request that calls a stored procedure called sp1:
... dbcarea.change_opts = 'Y'; dbcarea.dynamic_result_sets_allowed = 'Y'; dbcarea.req_ptr = "CALL sp1('SEL * FROM t1');"; ...
For a complete code example, see Using CLIv2 to Consume Dynamic Result Sets. You can use the code example to see the types of parcels in a response that Vantage returns to the caller of a stored procedure that creates result sets.
