ObjectExpansion |
DBTYPE_WSTR |
Optional. |
The restriction, ObjectExpansion, is available for every major object of Microsoft SQL Server 2005 Analysis Services (SSAS). The client typically uses restrictions to describe the OLAP objects for which the DDL is to be returned, and uses the ObjectExpansion restriction to define the degree of expansion in the returned DDL. The following table indicates whether the enumeration value is allowed for Alter Element (XMLA) commands.
| Enumeration Value | Description |
|---|---|
ReferenceOnly |
Returns only name/ID/timestamp/state for the requested. |
ObjectProperties |
Expands the requested object with no references to contained objects (includes expanded minor contained objects). |
ExpandObject |
Same as ObjectProperties, but also returns the name, ID, and timestamp for contained major objects. |
ExpandFull |
Fully expands the requested object recursively to the bottom of every contained object. |
