Oracle常用數(shù)據(jù)字典表?
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;
查看用戶下所有的表SQL>select * from user_tables;
顯示用戶信息(所屬表空間)select default_tablespace,temporary_tablespace?from dba_users where username='GAME';
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PROFILEselect 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_objectswhere 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_segmentswhere segment_name=upper('&table_name');
查看放在Oracle的內(nèi)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_segmentswhere 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_namefrom user_constraints where table_name = upper('&table_name');
SQL>select c.constraint_name,c.constraint_type,cc.column_namefrom user_constraints c,user_cons_columns ccwhere c.owner = upper('&table_owner') and c.table_name = upper('&table_name')and c.owner = cc.owner and c.constraint_name = cc.constraint_nameorder 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');
