dbms_metadata.get_ddl ...DDL 生成抛出语法错误

Question

我正在尝试使用 oracle 中的 dbms_metadata.get_ddl 函数从我们的开发数据库之一重新创建 table。例如

SELECT dbms_metadata.get_ddl('TABLE','ogaPatch2892_TAB','XVIEWMGR')from dual;

它确实生成了我需要的 DDL，但是运行它生成了一个错误

ORA-00904: : invalid identifier

以下是 DDL 语法：

CREATE TABLE "XVIEWMGR"."ogaPatch2892_TAB" OF XMLTYPE

您只需按以下步骤操作即可。无需指定存储参数。 Oracle 将自动选取数据库安装或由 DBA 设置时设置的默认值。

CREATE TABLE XVIEWMGR.ogaPatch2892_TAB OF XMLTYPE;
