我最近安装了SQL Developer。
我用id,name,city创建了名为Called Persons的小桌子,并在其中插入了一些值 现在,我想使用sql查询获取所创建表的DDL脚本...我该如何实现
* i使用人力资源
set pagesize 0 set long 90000 set feedback off set echo off spool scott_schema.sql SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name) FROM USER_TABLES u; SELECT DBMS_METADATA.GET_DDL('INDEX',u.index_name) FROM USER_INDEXES u; spool off;
但是该代码不起作用,任何人都可以修改并给我工作代码
下面是user_tables:desc
