Connection.openschema()....и басик "падает".

Народ, подскажите почему прибегает многоуважаемый Dr. Watson при обращении к методу OpenSchema объекта ADODB.Connection. Может быть из-за того что у меня ADO 2.5 ?
Кто-нибудь знает синтаксис этой самой OpenSchem'ы ?

SchemaID The GUID for a provider-schema schema query not defined by the OLE DB 1.1 specification. This parameter is required if QueryType is set to adSchemaProviderSpecific; otherwise, it is not used.

Remarks

The OpenSchema method returns information about the data source, such as information about the tables on the server and the columns in the tables.

The Criteria argument is an array of values that can be used to limit the results of a schema query. Each schema query has a different set of parameters that it supports. The actual schemas are defined by the OLE DB specification under the 'IDBSchemaRowset' interface. The ones supported in ADO 1.5 are listed above.

The constant adSchemaProviderSpecific is used for the QueryType argument if the provider defines its own non-sta
