          1、用戶
          查看當前用戶的缺省表空間:SQL>select username,default_tablespace from user_users;
          查看當前用戶的角色:SQL>select * from user_role_privs;
          查看當前用戶的系統(tǒng)權限和表級權限
          SQL>select * from user_sys_privs;
          SQL>select * from user_tab_privs;

          顯示當前會話所具有的權限:SQL>select * from session_privs;
          顯示指定用戶所具有的系統(tǒng)權限:SQL>select * from dba_sys_privs where grantee='GAME';
          顯示特權用戶:select * from v$pwfile_users;
          顯示用戶信息(所屬表空間)
          select default_tablespace,temporary_tablespace
          from dba_users where username='GAME';

          顯示用戶的PROFILE :select profile from dba_users where username='GAME';

          2、表
          查看用戶下所有的表 SQL>select * from user_tables;

          查看名稱包含log字符的表
          SQL>select object_name,object_id from user_objects  where instr(object_name,'LOG')>0;

          查看某表的創(chuàng)建時間
          SQL>select object_name,created from user_objects where object_name=upper('&table_name');

          查看某表的大小
          SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments
          where segment_name=upper('&table_name');

          查看放在ORACLE的內存區(qū)里的表
          SQL>select table_name,cache from user_tables where instr(cache,'Y')>0;

          3、索引
          查看索引個數(shù)和類別
          SQL>select index_name,index_type,table_name from user_indexes order by table_name;

          查看索引被索引的字段
          SQL>select * from user_ind_columns where index_name=upper('&index_name');

          查看索引的大小
          SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments
          where segment_name=upper('&index_name');

          4、序列號
          查看序列號,last_number是當前值
          SQL>select * from user_sequences;

          5、視圖
          查看視圖的名稱 SQL>select view_name from user_views;

          查看創(chuàng)建視圖的select語句
          SQL>set view_name,text_length from user_views;
          SQL>set long 2000; 說明:可以根據(jù)視圖的text_length值設定set long 的大小
          SQL>select text from user_views where view_name=upper('&view_name');

          6、同義詞
          查看同義詞的名稱
          SQL>select * from user_synonyms;

          7、約束條件
          查看某表的約束條件
          SQL>select constraint_name, constraint_type,search_condition, r_constraint_name
          from user_constraints where table_name = upper('&table_name');

          SQL>select c.constraint_name,c.constraint_type,cc.column_name
          from user_constraints c,user_cons_columns cc
          where c.owner = upper('&table_owner') and c.table_name = upper('&table_name')
          and c.owner = cc.owner and c.constraint_name = cc.constraint_name
          order by cc.position;

          8、存儲函數(shù)和過程
          查看函數(shù)和過程的狀態(tài)
          SQL>select object_name,status from user_objects where object_type='FUNCTION';
          SQL>select object_name,status from user_objects where object_type='PROCEDURE';

          查看函數(shù)和過程的源代碼
          SQL>select text from all_source where owner=user and name=upper('&plsql_name');
