Question

Write SQL DML statements that will modify data from within a database.
Using the Northwind database, write a SQL DML statement that will modify the data. Base it on the following requirements:

1.    Using the Northwind database, write a script to insert the following data:
       o    1 new Category
       o    Category Name = Fast Food
       o    Category Description = Quick and Easy Meals
       o    Provide a SELECT statement to show that the data was inserted.
2.    Add the following products for your new Fast-Food category.
       o    Product Name = French Fries
       o    Supplier Name = Ma Maison
       o    Category Name = Fast Food
       o    QuantityPerUnit = 20 Sticks
       o    UnitPrice = 4.99
       o    UnitsInStock = 10
       o    UnitsOnOrder = 25
       o    ReorderLevel = 10
       o    Disabled = 0
       o    Product Name = Hamburger
       o    Supplier Name = Grandma Kelly's Homestead
       o    Category Name = Fast Food
       o    QuantityPerUnit = 1 Patty
       o    Unit Price 6.99
       o    UnitsInStock = 0
       o    UnitsOnOrder = 50
       o    ReorderLevel = 5
       o    Disabled = 0
       o    Provide a SELECT statement to show that the data was inserted.
3.    In an attempt to liquidate some products, provide a script to set all products in the Confections category that have more than 50 units in stock to a price of $10, and disable them.
       o    2 records should be affected.
4.    Change the discount in the Order Details table on all orders of products of an ordered quantity of more than 50 to that of the largest discount ever given on any product.
      o    159 records should be affected
5.    You have decided against the new Fast-Food category. Provide a SQL statement to delete the Fast-Food category as well as any products assigned to that category.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
