查看当前用户的缺省表空间 SQL>select username,default_tablespace from user_users; 查看当前用户的角色 SQL>select * from user_role_privs; 查看当前用户的系统权限和表级权限 SQL>select * from user_sys_privs; SQL>select * from user_tab_privs; 查看用户下所有的表 SQL>select * from user_tables;

1.查看所有表空间大小.剩余量: select dbf.tablespace_name,dbf.totalspace "总量(M)",dbf.totalblocks as 总块数,dfs.freespace "剩余总量(M)",dfs.freeblocks "剩余块数",(dfs.freespace / dbf.totalspace) * 100 "空闲比例" from (select t.tablespace_name,su

-- 查看所有表空间的数据使用情况 SELECT Upper(F.TABLESPACE_NAME) "表空间名", D.TOT_GROOTTE_MB "表空间大小(M)", D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空间(M)", To_char(, 2), '990.99') || '%' "使用比", F.TOTAL_BYTES "空闲空间(M)", F.MAX_BYTE

场景:在做数据库巡检时,检查大表是必不可少的操作,可以查看各表占用表空间的大小 代码: as sizes,q.num_rows,t.segment_type from dba_segments t left join dba_tables q on t.segment_name=q.table_name and t.owner=q.owner where t.segment_type='TABLE' and t.tablespace_name='TS_AAA' --需要查看的表空间 desc

select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where a.object_id = b.object_id

SELECT a.object_id, a.session_id, b.object_nameFROM v$locked_object a, dba_objects bWHERE a.object_id = b.object_id

#描述:当执行如下SQL select * From XXX for Updata 发现表“XXX”被锁定 #只需要执行如下SQL 查看锁定该表的用户 SELECT object_name, machine, s.sid, s.serial# FROM gv$locked_object l, dba_objects o, gv$session s WHERE l.object_id = o.object_id AND l.session_id = s.sid; #效果图如下
