DISCOVER_SCHEMA_ROWSETS Rowset

Returns the names, restrictions, description, and other information for all enumeration values and any additional provider-specific enumeration values supported by the Microsoft XML for Analysis (XMLA) provider.

If you call the Discover method with the DISCOVER_SCHEMA_ROWSETS enumeration value in the RequestType element, the Discover method returns the DISCOVER_SCHEMA_ROWSETS rowset.

Rowset Columns

The DISCOVER_SCHEMA_ROWSETS rowset contains the following columns.

Column name	Type indicator	Length	Description

SchemaGuid	DBTYPE_GUID		The GUID of the schema.
Restrictions	DBTYPE_HCHAPTER		An array of the restrictions supported by the provider.
Description	DBTYPE_WSTR		A localizable description of the schema.
