Include the SQL statements in the body of the task CREATE TASK mytask .. AS INSERT INTO target1 SELECT .. FROM stream_s1 WHERE .. INSERT INTO target2 SELECT .. FROM stream_s1 WHERE ..

A stored procedure can have only one DML statement per stored procedure invocation and therefore the user should sequence stored procedure calls in the task definition CREATE TASK mytask

.. AS call stored_proc1(); call stored_proc2();

Use a stored procedure executing multiple SQL statements and invoke the stored procedure from the task. CREATE TASK mytask .... AS call stored_proc_multiple_statements_inside();
