Perhaps you are looking for ALTER TABLE?

Yes i am looking for alter which means adding Identity constraint for the employee_id column

Does eployee_id column contains unique values?

deenasudhakar 11-May-14 9:49am

Yes It behaves like primary key

Maciej Los 11-May-14 9:55am

Behaves like primary key is not equal to primary key.

For employee table employee_id is a primary key column

Try this:

Add or Remove Identity Property on Column

if it says

"Saving changes is not permitted in SQL Server"

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers.  clear the Prevent saving changes that require the table to be re-created check box.
