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('VIE
select count(*),machine from v$session group by machine 今天打算将一个数据库的索引在另一个测试库上重新创建一遍,研究了一下. set pagesize 0 set long 90000 set feedback off set echo off spool all_index.sql SELECT DBMS_METADATA.GET_DDL('INDEX',u.index_name) FROM USER_INDEXES u;spool of
select * from (select sql_text,sql_id,cpu_time from v$sql order by cpu_time desc) where rownum<=10 order by rownum asc ; select * from (select sql_text,sql_id,cpu_time from v$sqlarea order by cpu_time desc) where rownum<=10 order by rownum asc
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 ta
