PIVOT And UNPIVOT

If you have ever worked with Microsoft Access, you might have used the TRANSFORM statement to create a crosstab query.

Even though the similar functionality was missed in sql server 2000, we can achieve the same in SQL Server 2005 via the PIVOT operator with the SELECT statement.

The PIVOT operator can be used to transform a set of rows into columns while the UNPIVOT operator complements the PIVOT operator by allowing you to turn columns into rows.
