Hi yes it is possible with check constraints but here is also u have to make the condition like CREATE TABLE Test_ ( P_Id int IDENTITY (11) DayOfTheWeek varchar(255) NOT NULL CHECK (DayOfTheWeek 'Sunday' and DayOfTheWeek 'Saturday') FirstName varchar(255) Address varchar(255) City varchar(255) ) SELECT * FROM Test_ INSERT INTO Test_ VALUES ('sunday''ABC''AAM''BJP') //if you execute this insert statement it throw a error The INSERT statement conflicted with the CHECK constraint The statement has been terminated.

hi So what is problem in that if you are doing from front end just check name of day and and allow or don't allow to update if you are doing from back end so you also have to check name of the day and allowing or disallowing for update but there is not any option are available to set some property or condition directly on table .

Hi Shubham I can do it in front end coding. But I just want to know how I can achieve this using SQL Server. Actually this an interview question asked me by an interviewer. Thanks for your help.
