Using the INTO Clause
Use the INTO clause to specify where to store the values that the SPL function returns.
If an SPL function returns more than one value, the values are returned into the list of variables in the order in which you specify them. If an SPL function returns more than one row or a collection data type, you must access the rows or collection elements with a cursor.
You cannot prepare an EXECUTE PROCEDURE statement that has an INTO clause. For more information, see Alternatives to PREPARE ... EXECUTE FUNCTION ... INTO.
