ORA-40306: dm_nested types not supported by this algorithm

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.

ORA-40306：此算法不支持的dm_nested类型,
.原因： CREATE_MODEL例程的训练输入包含一个或多个dm_nested类型（DM_NESTED_NUMERICALS和/或DM_NESTED_CATEGORICALS）的列。决策树，O-Cluster和Adaptive Bayes网络算法当前不支持这些列。,
.操作：从输入数据源中删除这些数据类型的列。,
