AssignmentDiag Property

This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

The AssignmentDiag property enables SQL-92 standard behavior for NULL in aggregate, data truncation, divide-by-zero, and arithmetic overflow errors.

.AssignmentDiag [=value]


An expression that evaluates to an object in the Applies To list





HRESULT GetAssignmentDiag(LPBOOL pRetVal);
HRESULT SetAssignmentDiag(BOOL NewValue);

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.
