Stairway to Advanced T-SQL Level 6: Creating Rows Of Data Using The UNPIVOT Operator

The UNPIVOT operator does just the opposite of the PIVOT operator, which we looked at in the previous level. By using the PIVOT operator we can take multiple rows of data and create as single row as output. The UNPIVOT operator will take values from a single row and will create multiple rows. Microsoft introduced the UNPIVOT operator when they rolled out SQL Server 2005. In this level I will be showing you different examples of how to use the UNPIVOT operator.
