AnsiNullsStatus 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 AnsiNullsStatus property returns TRUE when the database object referenced depends on a table exhibiting SQL-92 NULL handling behavior.
Syntax
object
.AnsiNullsStatus
Parts
- object
An expression that evaluates to an object in the Applies To list
Data Type
Boolean
Modifiable
Read/write when a StoredProcedure2, Trigger2, UserDefinedFunction, or View2 object is created. Read-only when a StoredProcedure, Trigger, or View object is used, or after a StoredProcedure2, Trigger2, UserDefinedFunction, or View2 object is created.
Prototype (C/C++)
HRESULT GetAnsiNullsStatus(LPBOOL pRetVal);
Remarks
By default, Microsoft SQL Server creates columns that do not accept NULL unless the user explicitly declares the ability to accept NULL. Further, SQL Server returns TRUE when evaluating the expression NULL = NULL. These default behaviors are nonstandard.
Database and client connection options override default SQL Server behavior. If the default is overridden, tables created exhibit SQL-92 standard NULL handling and objects that depend upon those tables function as specified by SQL-92.
Note
If an application calls AnsiNullsStatus on an instance of SQL Server version 7.0 with the Table2 object, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
