Declare a cursor for stored procedure results

[Valery K]

Hello,

There are many samples how to create stored procedure and how to call it.
CREATE PROCEDURE `Results` (val INT)
BEGIN
SELECT * FROM customer WHERE id=val;
END

From manual "MySQL supports the very useful extension that allows the use of regular SELECT statements". This is great and it works from console or from Python in my tests.
mysql> call Results(1);

But I cannot (do not know how to) get the same result set when I call my stored procedure inside other stored procedure.

CREATE PROCEDURE `Calc` (val INT)
BEGIN
Call Results(1);
//Here I would like to read result set.
END

Is it possible to do? Probably I need to use Cursor. Are there any other solutions?

Thanks,
Valery.
