Supported Data Types for Data Source Nodes

Most of the basic Oracle data types are supported by the Data Source node. Object-based data types can be included, but each object type has to be well understood. Object data types require storage clauses to be defined at appropriate levels with the object hierarchy.

These data types are fully supported:

• VARCHAR2

• CHAR

• FLOAT

• NUMBER

• CLOB

• NESTED_NUMERICALS

• NESTED_CATEGORICALS

These data types are supported by Oracle Data Mining 12c Release 1 (12.1):

• BINARY_DOUBLE

• BINARY_FLOAT

• DM_NESTED_BINARY_DOUBLES

• DM_NESTED_BINARY_DOUBLES

• BLOB, for Text only

The BINARY data types and BLOB are supported by Oracle Data Miner if you are connected to Oracle Data Mining 12c Release 1 (1.2) or later.

These data types for date and time are partially supported:

• DATE

• TIMESTAMP

• TIMESTAMP_WITH_LOCAL_TIMEZONE

• TIMESTAMP_WITH_TIMEZONE

• TIMESTAMP_WITH_LOCAL_TIMEZONE

Oracle Database 12.1.0.2 supports JSON data in the following data types. Oracle Data Miner derives pseudo JSON data types from these data types:

• VARCHAR2

• CLOB

• BLOB

• RAW

• NCLOB

• NVARCHAR2
