Oracle Data Miner supports the following Oracle datatypes:
NUMBER

CHAR
DATE
CLOB
, BLOB
, BFILE
, LONG
, VARCHAR2
, XMLType
, CHAR
, RAW
, or LONG RAW
for text data only. For information about text mining, see Text Mining. Attributes of type DATE
are automatically converted to numbers before mining is performed by calculating the Julian date. For details, see Date Conversion.
Note: For certain algorithms, the build data can contain one column of text data. For details, see Text Mining.
Any column in a table that has a datatype not in this list is ignored by Oracle Data Miner. The ignored columns are automatically filtered out and are, therefore, not displayed.
