Значение свойства

A Boolean value. If true, the table has an imprecise computed column that is part of the primary key. If false, the table has no imprecise computed columns that are part of the primary key.

Замечания

Microsoft SQL Server 2005 allows an imprecise computed column to be part of the primary key, providing it is deterministic, and the column is explicitly declared with the persisted clause. Because of this, the corresponding primary key may have a different value on the Publisher and the Subscriber. Therefore, it is possible for the Distribution Agent to fail in applying an update or delete, resulting in a row not found error. Such a table cannot be published in a transactional article.

The HasImprecisePKColumn property can be retrieved by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.

The HasImprecisePKColumn property is available with SQL Server 2005 only.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
