For more information about selective XML indexes, see Selective XML Indexes (SXI).
- Create a Selective XML Index by Using Transact-SQL
Create a selective XML index by calling the CREATE SELECTIVE XML INDEX statement. For more information, see CREATE SELECTIVE XML INDEX (Transact-SQL).
The following example shows the syntax for creating a selective XML index. It also shows several variations of the syntax for describing the paths to be indexed, with optional optimization hints.
- Alter a Selective XML Index by Using Transact-SQL
Alter an existing selective XML index by calling the ALTER INDEX statement. For more information, see ALTER INDEX (Selective XML Indexes).
The following example shows an ALTER INDEX statement. This statement adds the path '/a/b/m' to the XQuery part of the index and deletes the path '/a/b/e' from the SQL part of the index created in the example in the topic CREATE SELECTIVE XML INDEX (Transact-SQL). The path to delete is identified by the name that was given to it when it was created.
