Data Mining Column Data Types
The data mining column data type is used as a tool to help the data mining algorithm provider handle input from training data and format output data for analysis.
You should not confuse the column data type with the column content type. For example, a column with a data type of TEXT can be used as a key, attribute, or relation column with equal ease. The column data type serves the data mining algorithm provider as a guideline for converting and processing the training data for the data mining column.
Supported data types are listed in Appendix A of the OLE DB 2.6 specification of March 1999 (version 2.6).
Note Not all data mining algorithm providers support all data types. For more information about supported column data types, see the data mining algorithm provider documentation.
