We can simplify this process through the use of a stored procedure. Let's create a procedure called sp_GetInventory that retrieves the inventory levels for a given warehouse. Here's the SQL code:

CREATE PROCEDURE sp_GetInventory
@location varchar(10)
AS
SELECT Product, Quantity
FROM Inventory
WHERE Warehouse = @location

Our Florida warehouse manager can then access inventory levels by issuing the command

EXECUTE sp_GetInventory 'FL'

The New York warehouse manager can use the same stored procedure to access that area's inventory.

EXECUTE sp_GetInventory 'NY'
