SQL

SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.

Queries

A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.

Question

How exactly would this be done?

6. Write a SELECT statement that returns these two columns:
CategoryName
The CategoryName column from the Categories table
The ProductID column from the Products table
ProductID
Return one row for each category that has never been used. (Hint: Use an outer join and only return
rows where the ProductID column contains a null value.)
7. Use the UNION operator to generate a result set consisting of three columns from the Orders table:
ShipStatus
A calculated column that contains a value of SHIPPED or NOT
SHIPPED
OrderID
The OrderID column
OrderDate
The OrderDate column
If the order has a value in the ShipDate column, the ShipStatus column should contain a value of
SHIPPED. Otherwise, it should contain a value of NOT SHIPPED.
Sort the result set by OrderDate.

1. Write a SELECT statement that returns four columns from the Products table: ProductCode,
ProductName, ListPrice, and DiscountPercent. The result set should be sorted by list price in
descending sequence.
2. Write a SELECT statement that returns these column names and data from the Products table:
The ProductName column
The ListPrice column
Date Added
The Date Added column
Return only the rows with a list price that's greater than 500 and less than 2000. Sort the result set in
descending sequence by the Date Added column.
3. Write a SELECT statement that returns these columns from the Orders table:
OrderID
The OrderID column
Order Date
The OrderDate column
ShipDate
The ShipDate column
Return only the rows where the ShipDate column contains a null value.
4. Write a SELECT statement that joins the Customers table to the Addresses table and returns these
columns: FirstName, LastName, Line1, City, State, ZipCode.
Product Name
ListPrice
Return one row for each customer, but only return addresses that are the shipping address for a
customer.
5. Write a SELECT statement that returns the ProductName and ListPrice columns from the Products
table. Return one row for each product that has the same list price as another product. Sort the result
set by ProductName.
(Hint: Use a self-join to check that the ProductID columns aren't equal but the ListPrice column is
equal.)
