ORA-40306: dm_nested types not supported by this algorithm

Cause: The training input to the CREATE_MODEL routine contains one or more columns of dm_nested type (DM_NESTED_NUMERICALS and/or DM_NESTED_CATEGORICALS). These columns are currently not supported for Decision Tree, O-Cluster, and Adaptive Bayes Network algorithms.

Action: Remove columns of these data types from the input data source.
