conditions, expressions

I have a table

CREATE TABLE [dbo].[CmnLanguage]
(
[Id] [char](2) NOT NULL CONSTRAINT PkCmnLanguage_Id PRIMARY KEY,
[EnglishName] [varchar](26) NOT NULL,
[NativeName] [nvarchar](26) NOT NULL,
[DirectionType] [smallint] NOT NULL,
[IsVisible] [bit] NOT NULL,
[CreatedDateTime] [datetime] NOT NULL DEFAULT GETDATE(),
[ModifiedDateTime] [datetime] NULL
)

We will use these 3 queries

select * from CmnLanguage where IsVisible = 0
select * from CmnLanguage where IsVisible = 1
select * from CmnLanguage

I want to make a method which handles these queries.

But at the back end on Stored Procedures

We have to write 3 queries

Which I don't want to do.

I want to minimize the queries and conditions

and want to just write one for these 3

Can any one do it?

How about this:

SET ANSI_NULLSONGOSET QUOTED_IDENTIFIERONGOCREATE PROCEDURE dbo.sp_MyProcedure(@.IsVisibleAS BIT =NULL)ASBEGINSELECT*FROM[dbo].[CmnLanguage]WHERE[IsVisible] =CASEWHEN @.IsVisibleISNULLTHEN [IsVisible]ELSE @.IsVisibleENDENDGO

Nice.

Very Useful.

Thanks.
