Hi
I analyzed a query in DTA.
It recommended the following indexes:
CREATE NONCLUSTERED INDEX iX_table1_Column1 ON dbo.table1 ( Column1 ) INCLUDE ( Column2)
CREATE NONCLUSTERED INDEX iX_table1_Column1 ON dbo.table1 ( Column1 ) INCLUDE ( Column3)
CREATE NONCLUSTERED INDEX iX_table1_Column1 ON dbo.table1 ( Column1 ) INCLUDE ( Column4, Column5)
Is it necessary to create all the 3 above mentioned indexes or
CREATE NONCLUSTERED INDEX iX_table1_Column1 ON dbo.table1 ( Column1 ) INCLUDE ( Column2, Column3, Column4, Column5)
will be sufficient.
Kindly suggest.
