Oracle查看當前用戶所在的表空間

1、用戶

查看當前用戶的缺省表空間

select username,default_tablespace from user_users; 

查看當前用戶的角色

select * from user_role_privs; 

查看當前用戶的系統權限和表級權限

select * from user_sys_privs; select * from user_tab_privs; 

顯示當前會話所具有的權限

select * from session_privs; 

顯示指定用戶所具有的系統權限

select * from dba_sys_privs where grantee='GAME'; 

2、表

查看用戶下所有的表

select * from user_tables; 

查看名稱包含log字符的表

select object_name,object_id from user_objects where instr(object_name,'LOG')>0; 

查看某表的創建時間

select object_name,created from user_objects where object_name=upper('table_name'); 

查看某表的大小

select sum(bytes)/(1024*1024) as "size(M)" from user_segments where segment_name=upper('table_name'); 

查看放在ORACLE的內存區里的表

select table_name,cache from user_tables where instr(cache,'Y')>0; 

3、索引

查看索引個數和類別

select index_name,index_type,table_name from user_indexes order by table_name; 

查看索引被索引的字段

select * from user_ind_columns where index_name=upper('index_name'); 

查看索引的大小

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

select * from user_sequences; 

5、視圖

查看視圖的名稱

select view_name from user_views; 

查看創建視圖的select語句

set view_name,text_length from user_views; set long 2000; 說明：可以根據視圖的text_length值設定set long 的大小 select text from user_views where view_name=upper('&view_name'); 

6、同義詞

查看同義詞的名稱

select * from user_synonyms; 

7、約束條件

查看某表的約束條件

select constraint_name, constraint_type,search_condition, r_constraint_name from user_constraints where table_name = upper('&table_name'); 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、存儲函數和過程

查看函數和過程的狀態

select object_name,status from user_objects where object_type='FUNCTION'; select object_name,status from user_objects where object_type='PROCEDURE'; 

查看函數和過程的源代碼

select text from all_source where owner=user and name=upper('&plsql_name');
