How to Reduce the Size of a Non-Clustered Index in SQL Server 2008

The Alter Index command can be used to reduce the size of a Non-Clustered Index. To reduce the size of a Non-Clustered Index, we will be using the DATA_COMPRESSION = ROW option to compress the Index by using row compression. The other options are None and Table

ALTER INDEX IX_WorkOrder_ProductID
ON Production.WorkOrder
REBUILD
WITH (DATA_COMPRESSION = ROW)
