Oracle获取创建对象的DDL脚本

例如，对tzq schema下的表 test2，查看DDL脚本的SQL如下：

SELECT SELECT dbms_metadata.get_ddl(upper('table'),upper('test2'),upper('tzq')) from dual;

查看 dbms_metadata.get_ddl()函数的定义

FUNCTION get_ddl (object_type     IN  VARCHAR2,name            IN  VARCHAR2,schema          IN  VARCHAR2 DEFAULT NULL,version         IN  VARCHAR2 DEFAULT 'COMPATIBLE',model           IN  VARCHAR2 DEFAULT 'ORACLE',transform       IN  VARCHAR2 DEFAULT 'DDL')RETURN CLOB;
