A computed column cannot be the target of an INSERT or UPDATE statement.For example, if the table has integer columns a and b, the computed column a + b may be indexed, but computed column a + DATEPART(dd, GETDATE()) cannot be indexed, because the value might change in subsequent invocations. However, if the computed column value is defined by a deterministic expression and the data type of the result is allowed in index columns, a computed column can be used as a key column in an index or as part of any PRIMARY KEY or UNIQUE constraint. A computed column cannot be used as a DEFAULT or FOREIGN KEY constraint definition or with a NOT NULL constraint definition.You can specify an expression for a computed column in SQL Server by using SQL Server Management Studio or Transact-SQL.
