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.
Rowset Columns
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:
|
|
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. |
