This statement resumes execution of a procedure that returns result sets. The procedure executes until the next result set
(SELECT statement with no INTO clause) is encountered. If the procedure completes and no result set is found, the SQLSTATE_PROCEDURE_COMPLETE
warning is set. This warning is also set when you RESUME a cursor for a SELECT statement.
The RESUME statement is not supported in Interactive SQL. To view multiple result sets in Interactive SQL, set the isql_show_multiple_result_sets
option to On, or choose Tools » Options, and then select Show Multiple Result Sets on the Results tab.
