EQUALS_PATH

The EQUALS_PATH condition determines whether a resource in the Oracle XML database can be found in the database at a specified path.

Use this condition in queries to RESOURCE_VIEW and PATH_VIEW. These public views provide a mechanism for SQL access to data stored in the XML database repository. RESOURCE_VIEW contains one row for each resource in the repository, and PATH_VIEW contains one row for each unique path in the repository.

equals_path::=

Text description of equals_path

This condition applies only to the path as specified. It is similar to but more restrictive than UNDER_PATH.

The optional correlation_number argument correlates the EQUALS_PATH condition with its ancillary functions PATH and DEPTH.

Example

The view RESOURCE_VIEW computes the paths (in the any_path column) that lead to all XML resources (in the res column) in the database repository. The following example queries the RESOURCE_VIEW view to find the paths to the resources in the sample schema oe. The EQUALS_PATH condition causes the query to return only the specified path:

SELECT ANY_PATH FROM RESOURCE_VIEW
   WHERE EQUALS_PATH(res, '/sys/schemas/OE/www.oracle.com')=1;

ANY_PATH
-----------------------------------------------
/sys/schemas/OE/www.oracle.com

Compare this example with that for UNDER_PATH.
