Help with Indexes.

$

Hi,

We have got table with 27087719 rows and when I execute simple SELECT statement it tool 14:30 minutes to give me the output, and when I filtered the columns to just 3 columns and again fired SELECT statement, it took 7:30 minutes to give me the output.

And the indexes we have on that table are as follows:

USE [ABC]

GO

/****** Object:  Index [IDX_TABLE NAME]    

CREATENONCLUSTEREDINDEX [IDX_NAME]ON [dbo].[TABLE NAME]

(

      [Type]ASC,

      [Value]ASC

)WITH(PAD_INDEX =OFF,STATISTICS_NORECOMPUTE  =OFF, SORT_IN_TEMPDB= OFF,IGNORE_DUP_KEY=OFF,DROP_EXISTING= OFF,ONLINE=OFF,ALLOW_ROW_LOCKS  =ON, ALLOW_PAGE_LOCKS  = ON,FILLFACTOR= 90) ON [ABC_TABLE NAME]

GO

USE [ABC]

GO

/****** Object:  Index [PK_TABLE NAME]    

ALTERTABLE [dbo].[TABLE NAME]ADD  CONSTRAINT [PK_TABLE NAME]PRIMARYKEY CLUSTERED

(

      [Queue]ASC

)WITH(PAD_INDEX =OFF,STATISTICS_NORECOMPUTE  =OFF, SORT_IN_TEMPDB= OFF,IGNORE_DUP_KEY=OFF,ONLINE= OFF,ALLOW_ROW_LOCKS =ON,ALLOW_PAGE_LOCKS  =ON, FILLFACTOR= 90)ON [ABC_TABLE NAME]

GO

I have tuned this table in DTA, but no output of recommendation.

Please advice me how can I improve this performance of this table, please suggest me proper indexes.

Thanks in advance.
