one of the interviewer asked the question about updating...so i have added test table like below...
/****** Object: Table [dbo].[mytable] Script Date: 09/25/2013 13:10:59 ******/
SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
CREATE TABLE [dbo].[mytable](
[city] [nchar](10) NULL
) ON [PRIMARY]
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....
Not all questions asked by interviewers have a positive answer. Sometimes they ask the "wrong" thing to see what you'll say.

Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
