Question 1
Write stored procedures in SQL to implement the purchase and sale transactions.
The purchase transaction inputs are : vendor_id, date, product_id, qty, purchase_price ...]
// more than one product can be purchased at a time from a vendor
The purchase transaction creates a record of the purchase in appropriate tables.
The sale transaction inputs are : customer_id, date, product_id, qty, sale_price ...]
// more than one product can be sold at a time to a customer.
The sale transaction creates a record of the sale in appropriate tables.
You can assume a given set of products, customers, and vendors and make sample data on your own to test the transactions.
Submit a snapshot of your database with sample data, and the results of executing sale and purchase transactions.
Question 2
Write a stored procedure to generate a stock report for a date range.
select stock_report (date1 date, date2 date);
This report shows the following columns
product_id product_name opening_balance qty_in qty_out qty_net closing_balance_date2
The report calculates opening balances from "beginning of time" to date1, then computes qty_in and qty_out using purchases and sales respectively, then calculates qty_net by qty_in and qty_out between date1 and date2 and finally computes the closing balance on date2.
You may need to write multiple sql statements inside the body of the stock_report stored procedure.
You can use any language for database programming, including PLV8 (embeddeded javascript), PL/SQL or any other embedded language embedded in a SQL server.
Bonus : Can you make the report more efficient ?
