sp_db_selective_xml_index (Transact-SQL)

  • Makale

Applies to: SQL Server

Enables and disables selective XML index (SXI) functionality on a SQL Server database. If called without any parameters, the stored procedure returns 1 if SXI is enabled on a particular database.

Note

In SQL Server 2014 (12.x) and later versions, the SXI functionality can't be disabled. This feature will be removed in a future version of SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
