AssignmentDiag Property
В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.
The AssignmentDiag property enables SQL-92 standard behavior for NULL in aggregate, data truncation, divide-by-zero, and arithmetic overflow errors.

Замечания
If TRUE, SQL-92 standard behavior is enabled. If NULL is involved in an aggregate, data is truncated on an INSERT or UPDATE statement execution, or a divide-by-zero or arithmetic overflow occurs, these events follow:
- The statement is stopped.
- Any transactions are rolled back.
- An error is returned to the client.
If FALSE, SQL-92 behavior is disabled. If NULL is returned for an affected column or data is truncated on an INSERT or UPDATE, these events follow:
- Transactions are not rolled back.
- The client receives either an error, success with information, or a success return code.
