    hi,

    one of the interviewer asked the question about updating...so i have added test table like below...

    USE [Practice]

    GO

    /****** Object: Table [dbo].[mytable] Script Date: 09/25/2013 13:10:59 ******/

    SET ANSI_NULLS ON

    GO

    SET QUOTED_IDENTIFIER ON

    GO

    CREATE TABLE [dbo].[mytable](

    [city] [nchar](10) NULL

    ) ON [PRIMARY]

    GO

    and i have inserted values like

    insert into mytable (city) values ('A')

    so now i want to write update querty to update city value from A to B then B to A by using any query....
