MSCEWI1082

Auto-Generated code in order to support output parameters in Snowflake Scripting

Severity

Low

Description

This warning is used to inform that some statements are being added to the procedures with output parameters in order to emulate their functionality. The auto-generated code is being added in the procedure with the output parameters and also where this procedure is being called.

Example Code

Input

CREATE OR REPLACE PROCEDURE proc_with_output_parameters(param1 OUT NUMBER, param2 IN OUT NUMBER)
IS
BEGIN
param1 := 123;
param2 := 456;
END;
CREATE OR REPLACE PROCEDURE proc_calling_proc_with_output_parameters
IS
var1 NUMBER;
var2 NUMBER;
BEGIN
proc_with_output_parameters(var1, var2);
END;
