不多说，直接上干货
1、查询当前用户下表的创建语句
select dbms_metadata.get_ddl(\'TABLE\',\'ux_future\') from dual;
2、查询其他用户下表的创建语句
select dbms_metadata.get_ddl(\'TABLE\',\'ux_future\',\'Admin\') from dual;
3、查询表的index
select index_name,index_type,table_name from user_indexes where table_name = \'ux_future\';
4、查询当前用户下索引的创建语句
select dbms_metadata.get_ddl(\'INDEX\',\'ux_future_xx\') from dual;
5、查询其他用户下索引的创建语句
select dbms_metadata.get_ddl(\'INDEX\',\'ux_future_xx\',\'Admin\') from dual;
6、查询当前用户下视图的创建语句
select dbms_metadata.get_ddl(\'VIEW\',\'ux_future\') from dual;
7、查询其他用户下视图的创建语句
select dbms_metadata.get_ddl(\'VIEW\',\'ux_future\',\'Admin\') from dual;
8、查询表的约束
select owner,table_name,constraint_name,constraint_tpye from user_cinstraints where table_name = \'ux_future\';
9、查询创建主键的语句
select dbms_metadata.get_ddl(\'CONSTRAINT\',\'ux_future_xp\') from dual;
10、查询创建外键的语句
select dbms_metadata.get_ddl(\'REF_CONSTRAINT\',\'ux_future_kk\') from dual;
11、查询一个用户下所有表、索引、存储过程、函数的ddl
select dbms_metadata.get_ddl(u.object_type,u.object_name) from user_objects u where u.object_type in (\'TABLE\',\'INDEX\',\'PROCEDURE\',\'FUNCTION\');
12、查询所有表空间的ddl
select dbms_metadata.get_ddl(\'TABLESPACE\',t.tablespace_name) from dba_tablespaces t;
13、查询创建用户的语句
select dbms_metadata.get_ddl(\'USER\',u.username) from dba_users u;
