However, this value is purely advisory, and may change from one release of ADO MD to another. Your code should only depend on the name, not the actual value, of enumerated constants. The following enumerations are defined. - [SchemaObjectTypeEnum](../../../ado/reference/ado-md-api/schemaobjecttypeenum.md) - [MemberTypeEnum](../../../ado/reference/ado-md-api/membertypeenum.md) ## See Also [ADO MD API Reference](../../../ado/reference/ado-md-api/ado-md-api-reference.md) [ADO MD Code Examples](../../../ado/reference/ado-md-api/ado-md-code-examples.md) [ADO MD Collections](../../../ado/reference/ado-md-api/ado-md-collections.md) [ADO MD Methods](../../../ado/reference/ado-md-api/ado-md-methods.md) [ADO MD Object Model](../../../ado/reference/ado-md-api/ado-md-object-model.md) [ADO MD Objects](../../../ado/reference/ado-md-api/ado-md-objects.md) [ADO MD Properties](../../../ado/reference/ado-md-api/ado-md-properties.md)
