Esse recurso será removido em uma versão futura do Microsoft SQL Server. Evite usar esse recurso em desenvolvimentos novos e planeje modificar os aplicativos que atualmente o utilizam.

The AnsiNullsStatus property returns TRUE when the database object referenced depends on a table exhibiting ISO NULL handling behavior.

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 View2object is created.

Comentários

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 ISO standard NULL handling and objects that depend upon those tables function as specified by ISO.

ObservaçãoObservação

If an application calls AnsiNullsStatuson 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.
