Attributes

Attribute	Description
AllowOverwrite	Optional Boolean attribute. If set to True, the objects defined in the ObjectDefinition element can overwrite existing objects on the Analysis Services instance. If this attribute is omitted or set to False, the presence of an existing object generates an error.
Scope	Optional Enum attribute. Defines the duration of objects defined in the ObjectDefinition element. If this attribute is omitted, the objects defined in the ObjectDefinition element are persisted on the Analysis Services instance. The following values are available: Session The objects defined in the ObjectDefinition element exist only for the duration of the XML for Analysis (XMLA) session. Note When using the Session setting, the ObjectDefinition element can only contain Dimension, Cube, or MiningModel ASSL elements.

AllowOverwrite

Optional Boolean attribute. If set to True, the objects defined in the ObjectDefinition element can overwrite existing objects on the Analysis Services instance. If this attribute is omitted or set to False, the presence of an existing object generates an error.

Scope

Optional Enum attribute. Defines the duration of objects defined in the ObjectDefinition element. If this attribute is omitted, the objects defined in the ObjectDefinition element are persisted on the Analysis Services instance. The following values are available:

Session

The objects defined in the ObjectDefinition element exist only for the duration of the XML for Analysis (XMLA) session.

Note

When using the Session setting, the ObjectDefinition element can only contain Dimension, Cube, or MiningModel ASSL elements.

Remarks

Each Create operation creates one major object under a parent given by the ParentObject element. If the parent object is omitted, it is assumed to be the destination Analysis Services instance. This generates an error if the parent of a major object is not the destination instance.

Example

The following example creates an empty database named Test Database on an Analysis Services instance.

<Create xmlns="https://schemas.microsoft.com/analysisservices/2003/engine">
   <ObjectDefinition>
      <Database xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
         <Name>Test Database</Name>
         <Description>A test database.</Description>
      </Database>
   </ObjectDefinition>
</Create>
