AssignmentDiag Property

后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

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

语法

object.AssignmentDiag [=value]

Parts

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

  • value
    TRUE or FALSE

Data Type

Boolean

Modifiable

Read/write

Prototype (C/C++)

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

注释

If TRUE, ISO 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, ISO 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.
