Case 1In this case, you use SQL Worksheet to create stored procedures that process incoming shipment items that Clearwater Traders receives. The first stored procedure updates the SHIPMENT_L1NE table and then calls a second stored procedure that updates the quantity 0n hand (QOH) of item in the INVENTORY table. Save all commands in a text file named Lab4Case1.sql. a. In SQL Worksheet, create a stored procedure named UPDATE_INV_QOH that receives input parameters of all inventory ID and an update quantity, and then uses these values to update the INV_QOH field in the INVENTORY table. b. In a new SQL Worksheet, create a second procedure named UPDATE_ SHIPMENT_L1NE that receives input parameters of an existing shipment ID and inventory ID. The procedure should update the associated SHIPMENT_LINE record based on the input values, using the system date as the date received. It should then call the UPDATE_INV_QOH procedure to update the associated inventory quantity on hand using the shipment line quantity. c. Write an anonymous PL/SQL program to call the UPDATE_SHIPMENT_ LINE procedure and pass to it values to show that the units of inventory ID 5 were received for shipment ID 3. Execute the anonymous PL/SQL program, and then use SELECT statements to display the updated rows from the two tables to verify the procedures worked correctly.
