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.

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