Method Detail

getObjectNames

public java.sql.ResultSet getObjectNames(java.lang.String schemaPattern,
                                         javax.datamining.NamedObject objectType,
                                         java.lang.String objectNamePattern,
                                         javax.datamining.Enum minorType_1,
                                         javax.datamining.Enum minorType_2)

This method is added as an Oracle extension to provide listing of mining object names across schemas. It returns the java.sql.ResultSet object with the following columns:

1. SCHEMA_NAME String => Name of the schema (can be null)
2. TYPE String => Type of the object (NamedObject object types)
3. NAME String => Name of the object
4. MINOR_TYPE_1 String => Mining objects can have minor/sub types. For example, model object can have function and algorithm as minor types. Table in this comment lists the allowed minor types based on the object type.
5. MINOR_TYPE_2 String => Mining objects can have more than one minor type. If they have second minor type, then this column is used.
6. CREATION_DATE Timestamp => Date when this object was created
7. DESCRIPTION String => Description of the object

Following list shows the possible minor types for different mining objects.

• Model
  • MINOR_TYPE_1 - Mining Function name
  • MINOR_TYPE_2 - Mining Algorithm name
• BuildSettigs
  • MINOR_TYPE_1 - Mining Function name
  • MINOR_TYPE_2 - Null
• TestMetrics
  • MINOR_TYPE_1 - Mining Function name
  • MINOR_TYPE_2 - Null
• Task
  • MINOR_TYPE_1 - Task type
  • MINOR_TYPE_2 - Null
• CostMatrix
  • MINOR_TYPE_1 - Null
  • MINOR_TYPE_2 - Null

Parameters:

schemaPattern - a schema name pattern; must match the schema name as it is stored in the database; "" retrieves those without a schema; null means that the schema name should not be used to narrow the search

objectType - object type to include; null returns all types

objectNamePattern - an object name pattern; must match the mining object name as it is stored in the database

minorType_1 - primary minor type to include; it is ignored when the object type argument is not specified; null returns all primary minor types

minorType_2 - secondary minor type to include; it is ignored when the object type argument is not specified; null returns all secondary minor types

Returns:
