DMSCHEMA_MINING_MODELS Rowset

Updated: 14 April 2006

Enumerates the data mining models in the current catalog. The DMSCHEMA_MINING_MODELS schema rowset is quite similar to the DBSCHEMA_TABLES schema rowset and can be used the same way. Use the DMSCHEMA_MINING_MODELS rowset to obtain information about the mining models contained within a database. The DMSCHEMA_MINING_MODELS rowset can include information such as the names, types, and mining algorithms associated with each mining model.

The DMSCHEMA_MINING_MODELS rowset contains the following columns.

Column name Type indicator Length Description

MODEL_CATALOG

DBTYPE_WSTR

The catalog name. Populated with the name of the database of which the model is a member.

MODEL_SCHEMA

DBTYPE_WSTR

The unqualified schema name. This column is not supported by Microsoft SQL Server 2005 Analysis Services (SSAS); it always contains NULL.

MODEL_NAME

DBTYPE_WSTR

The mining model name. This column contains the name of the mining model, and it is never empty.

MODEL_TYPE

DBTYPE_WSTR

The model type.

MODEL_GUID

DBTYPE_GUID

The GUID of the model.

DESCRIPTION

DBTYPE_WSTR

A user-friendly description of the model.

MODEL_PROPID

DBTYPE_UI4

The property ID of the model. This column is not supported by Analysis Services; it always contains NULL.

DATE_CREATED

DBTYPE_DBTIMESTAMP

The date on which the model was created.

DATE_MODIFIED

DBTYPE_DBTIMESTAMP

The date on which the model definition was last modified.

SERVICE_TYPE_ID

DBTYPE_UI4

An enumerated type that identifies the data mining algorithm used by the model. This enumerated type may be one of the following values:

  • DM_SERVICETYPE_CLASSIFICATION
  • DM_SERVICETYPE_SEGMENTATION

SERVICE_NAME

DBTYPE_WSTR

A string that contains the provider-specific name for the data mining algorithm used by the model.

CREATION_STATEMENT

DBTYPE_WSTR

A string that contains the statement that was used to create the mining model.

PREDICTION_ENTITY

DBTYPE_WSTR

A string that contains a comma-delimited list indicating which mining columns can be predicted.

IS_POPULATED

DBTYPE_BOOL

A Boolean that indicates whether the model is populated.

TRUE if the model is populated. Otherwise it contains FALSE.

MINING_PARAMETERS

DBTYPE_WSTR

The parameter settings with which the model was created.

MINING_STRUCTURE

DBTYPE_WSTR

The mining structure on which the model is based.

LAST_PROCESSED

DBTYPE_DBTIMESTAMP

The date the model was last processed.

MSOLAP_IS_DRILLTHROUGH_ENABLED

DBTYPE_BOOL

A Boolean that indicates whether the model supports drill-through.

The DMSCHEMA_MINING_MODELS rowset can be restricted on the columns in the following table.
