当使用脚本从这或这源代码克隆模式时，它在我们正在使用的Oracle11g中非常正常。最近，我们转向了Oracle 19c，克隆不再正常工作了。虽然乍一看，一切看起来都很好，但仔细观察，索引组织的表是空的。当我检查这些表的结构时，缺少索引和约束。

源模式中的索引组织表示例：

CREATE TABLE some_table
(
    id1    INTEGER NOT NULL,
    id2    INTEGER NOT NULL,
    CONSTRAINT pk_some_table PRIMARY KEY (id1, id2) ENABLE VALIDATE
)
ORGANIZATION INDEX
/

CREATE INDEX ix_some_table_01
    ON some_table (id1)
/

CREATE INDEX ix_some_table_02
    ON some_table (id2)
/

ALTER TABLE some_table
    ADD (CONSTRAINT fk_some_table_01 FOREIGN KEY (id1) REFERENCES parent_table1 (id) ENABLE VALIDATE)
/

ALTER TABLE some_table
    ADD (CONSTRAINT fk_some_table_02 FOREIGN KEY (id2) REFERENCES parent_table2 (id) ENABLE VALIDATE)
/

以及目标(克隆)模式中的相同表：

CREATE TABLE some_table
(
    id1    INTEGER NOT NULL,
    id2    INTEGER NOT NULL,
    CONSTRAINT pk_some_table PRIMARY KEY (id1, id2) ENABLE VALIDATE
)
ORGANIZATION INDEX
/

而且，正如我所提到的，没有数据被克隆，而克隆的索引组织表则是空的。我怀疑克隆过程试图在索引本身之前创建约束(使用索引)，但我不确定这是否是原因。

任何帮助都将不胜感激。谢谢!
