HasSQLVariantColumn 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 HasSQLVariantColumn property returns TRUE if the referenced table has a sql_variant column.

语法

object
.HasSQLVariantColumn

Parts

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

Data Type

Boolean

Modifiable

Read-only

Prototype (C/C++)

HRESULT GetHasSQLVariantColumn(LPBOOL pRetVal);

注释

An application can call the HasSQLVariantColumn property to determine whether a table contains a sql_variant column. This action can be useful when preparing to replicate to a heterogeneous Subscriber, because not all heterogeneous databases support the sql_variant data type.

注意注意

If an application calls HasSQLVariantColumn on an instance of Microsoft SQL Server version 7.0, FALSE is returned.
