Question

我正在尝试使用oracle中的dbms_metadata.get_ddl函数从我们的某个开发数据库重新创建一个表。例如

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

它确实产生了我需要的DDL，但运行它会产生错误

ORA-00904 ::无效标识符

以下是DDL sytax：

您需要做的就像下面所做的一样。无需指定存储参数。 Oracle将自动获取DBA安装或设置数据库时设置的默认值。

CREATE TABLE XVIEWMGR.ogaPatch2892_TAB OF XMLTYPE;

dbms_metadata.get_ddl ... DDL产生抛出语法错误
