The following two examples demonstrate Index Creation functionality.
The first example creates a High_Non_Group
(
HNG) index called 
ShipIx on
the 
ShipDate column of the 
SalesOrderItems table.
CREATE HNG INDEX ShipIx 
  ON dbo.SalesOrderItems (ShipDate)
 
The second example creates a Low_Fast (
LF)
index called 
SalesOrderRegionIX on the 
Region column
of the 
SalesOrder table.
CREATE LF INDEX SalesOrderRegionIx 
  ON dbo.SalesOrder (Region)
