BUG #: 12486 (Plato7.x)



SYMPTOMS
If you create a data mining provider to be compliant with the OLE DB for Data Mining specifications, the provider may fail the compliance test, even though the provider follows all the OLE DB Data Mining specifications.



CAUSE
The conformance utilities provided with the MDAC SDK tests the new providers for compliance against the Microsoft Provider for Data Mining. The Microsoft provider is not compliant with the OLE DB for Data Mining specifications in some of the schema rowset columns. For the following columns, the Microsoft Data Mining provider uses DBTYPE_UI4 for the data type, which should be DBTYPE_I4 as noted in the OLE DB Data Mining specifications:
 * TRAINING_COMPLEXITY


 * PREDICTION_COMPLEXITY


 * EXPECTED_QUALITY


 * SCALING


 * CONTROL


 * NODE_TYPE


 * ATTRIBUTE_VALUE



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft SQL Server 2000 Analysis Services. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

WORKAROUND
To work around this problem, make sure that your Data Mining provider uses the DBTYPE_UI4 data type for the columns specified in the &quot;Cause&quot; section.



STATUS
Microsoft has confirmed that this is a problem in Microsoft SQL Server 2000 Analysis Services.

This problem was first corrected in Microsoft SQL Server 2000 Analysis Services Service Pack 2.
