FIX: Data Types for Some Columns in MINING_SERVICES Schema Rowset are not Compliant with the OLE DB Data Mining Specifications (308963)

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
