Question

This my table

CREATE TABLE [dbo].[StandardRoom](
[StandardRoomId] [char](4) NOT NULL,
[RoomType] [varchar](15) NULL,
[Rate] [smallmoney] NULL,
[RoomDeparment] [varchar](15) NULL,
[PlaceNb] [char](1) NULL,
[PatientId1] [char](12) NULL,
[PatientId2] [char](12) NULL,
[PatientId3] [char](12) NULL,
[PatientId4] [char](12) NULL,
[BedId1] [char](4) NOT NULL,
[BedId2] [char](4) NULL,
[BedId3] [char](4) NULL,
[BedId4] [char](4) NULL,
[Full] [char](1) NOT NULL,

So I want to create a view to see (BedId1 if PatientId1=null), (BedId2 if PatientId2=null)
(BedId3 if PatientId3 = null), (BedId4 if PatientId4 =null)

Thank’s for helping me!

For guys voting down because They think this table is not normalize, Yes Its true , but I Have my reason to do this in the context of my DATABASE…

CREATE VIEW [dbo].[v_StandardRoom]
AS
select [StandardRoomId] ,
[RoomType] ,
[Rate] ,
[RoomDeparment] ,
[PlaceNb] ,
[PatientId1] ,
[PatientId2] ,
[PatientId3] ,
[PatientId4] ,
case when PatientId1 IS NULL then [BedId1] 
when PatientId2 IS NULL then [BedId2] 
when PatientId3 IS NULL then [BedId3] 
when PatientId4 IS NULL then [BedId4] 
end as BedId,
[Full] 
from [dbo].[v_StandardRoom]
