Based on the in class examples from Flat file function proc example.sql

$1.$ Create and test a Function named $\backslash ($ f$\_\{-\}\backslash )$add$20$ that accepts one integer parameter. The function then adds $20$ and returns the result as an Integer.

This should work against your function: select f$\_$add$20(3)$ from dual;

$2.$ Create and test a Procedure named $\backslash ($ p$\_\{-\}\backslash )$add$2$Numbers that accepts two integers as parameters. The Procedure should then add the integers together and return an integer result.

The following should work against your Procedure:

call p$\_$add$2$Numbers $(1,3,$@mySum$)$;

select @mySum;
