【Oracle】查看表或视图的创建语句

这里用到的是Oracle的DDL语句的用法

用于获得某个schema下所有的表、索引、视图、存储过程、函数的DDL

set pagesize 0
set long 90000
set feedback off
set echo off
spool schema_ddl.sql
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name,u.owner) FROM DBA_TABLES u;
SELECT DBMS_METADATA.GET_DDL('VIEW',u.view_name,u.owner) FROM DBA_VIEWS u;
SELECT DBMS_METADATA.GET_DDL('INDEX',u.index_name,u.owner) FROM DBA_INDEXES u;
select dbms_metadata.get_ddl('PROCEDURE',u.object_name, u.owner,) from dba_objects u where u.object_type = 'PROCEDURE';
select dbms_metadata.get_ddl('FUNCTION',u.object_name, u.owner,) from dba_objects u where u.object_type = 'FUNCTION';
spool off;

表空间的DDL

select dbms_metadata.get_ddl('TABLESPACE','表空间名称') from dual;

单个用户的DDL

select dbms_metadata.get_ddl('USER','EPAY_USER') from dual;
