文档解释
ORA-39269: Cannot alter a column of type LONG to anything other than LOB.
Cause: DBMS_METADATA_DIFF was comparing two table columns, the first of type LONG, the second of a data type other than LOB. There is no SQL ALTER statement to modify a long data type to anything other than a CLOB or NCLOB.
Action: The difference cannot be eliminated with an SQL ALTER statement.
，
ORA-39269错误表明，无法将LONG类型的列更改为LOB类型以外的类型。
