Comentários
A computed column can be used as a key column in an index or as part of any primary key or unique constraint, if the computed column value is defined by a deterministic expression and the data type of the result is allowed in indexed columns.
An application can use this property to determine if a computed column that depends on a user-defined function can be used in an index.
