1. Lab 9 Moving on to implementation and testing the package

2. Tasks for today in the lab Look at the access required to: –Add data to another schema –Update data in another schema –Run procedures / functions in another schema. Try to run the procedures in custorders. Have your team ERD checked for accuracy. Start to build your team schema.

3. Testing the package To test the package, each student needs: –Insert access to the customer table –Insert access to the corder table –Insert access to the corderline table –Update access to the stock_level column of the stock table Also: –Insert access to all three error tables. –Execute access to the contents of the builder.custorders package.

4. Granting access… If Oliver O’Connor takes the role of salesperson: –Grant insert on customer to ooconnor; –Grant insert on corder to ooconnor; –Grant insert on corderline to ooconnor; –Grant update on stock(stock_level) to ooconnor; –Grant insert on corder_error to ooconnor; –Grant insert on restock to ooconnor; –Grant insert on corderline_error to ooconnor; –Grant execute on custorders to ooconnor; And Art Sloan takes up the role of foreman: –Grant update on corder(staffissued) to asloan; –Grant insert on corder_error to asloan; –Grant insert on corderline_error to asloan;

5. Your access Every student has been given access to both the foreman role and the salesperson role. You can run the procedures yourselves. Try to add the following order: –Brad Pitt from Hollywood Boulevard, Hollywood, Los Angeles, wants to buy 4 Brass Hinges, a power saw and 4 cans of beer. The source of custorders is in the P: drive.

6. To add the order: Set up an anonymous block. Add declarations as required. Count the customers whose name is ‘Brad Pitt’ and put the result into an integer rowcnt. If there is > 0, select the customer_id into a variable Otherwise, add the customer using add_customer. Add an order, with today’s date and the customer number (the order number will be generated. Let the staffpaid be 51). For each stock item being ordered: –Check to see if it exists (as you did for the customer) –If so, add a corderline for it, otherwise display an error.

7. Team ERD If you think you’re nearly there: –Check with Patricia O’Byrne or Oliver O’Connor to see if you have a reasonable set of tables, attributes and relationships. –Either Model it in ERWin and generate the CREATE statements. –Or Write the CREATE statements, ensuring referential integrity. If you don’t think you’re nearly there: –Flag the problem with Patricia O’Byrne –Consult Patricia O’Byrne or Mark Foley in the tutorial.

8. Lab test results Lab test results have been posted. If you have any questions about your result: –Art Sloan can show you: the full result sheet The sample solutions –Please note, there are other correct solutions. In cases where hyphens were used instead of underscores, marks were not deducted. In cases where students could not find the driver name, any field specific to the driver table sufficed.
