ORA-14302: only one list of added-LOB-storage-clauses can be specified in a statement
Cause: While parsing an ALTER TABLE ADD COLUMN statement, one list of added-LOB-storage-clauses was parsed when another list of added-LOB-storage-clauses was encountered. There cannot be more than one list of added-LOB-storage-clauses in a statement; all added-LOB-storage-clauses must be combined into one list.
Action: Combine all of the lists of added-LOB-storage-clauses into one list and retry the statement.
ORA-14302：只能在语句中指定一个添加的LOB存储子句列表。
1）检查语句中是否指定了多个LOB存储子句列表，
2）检查根据官方文档要求，查找是否有未知LOB参数，
3）分别执行ALTER TABLE命令添加每个LOB存储，
4）正确执行ALTER TABLE命令更改LOB存储。
