Will creating index help in this case
- by The King
I'm still a learning user of SQL-SERVER2005.
Here is my table structure
CREATE TABLE [dbo].[Trn_PostingGroups](
[ControlGroup] [char](5) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[PracticeCode] [char](5) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[ScanDate] [smalldatetime] NULL,
[DepositDate] [smalldatetime] NULL,
[NameOfFile] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[DepositValue] [decimal](11, 2) NULL,
[RecordStatus] [char](1) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
CONSTRAINT [PK_Trn_PostingGroups_1] PRIMARY KEY CLUSTERED
(
[ControlGroup] ASC,
[PracticeCode] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
Scenario 1 : Suppose I have a query like this...
Select * from Trn_PostingGroups where PracticeCode = 'ABC'
Will indexing on Practice Code seperately help me in making my query faster??
Scenario 2 :
Select * from Trn_PostingGroups
where
ControlGroup = 12701
and PracticeCode = 'ABC'
and NameOfFile = 'FileName1'
Will indexing on NameOfFile seperately help me in making my query faster ??
