ORACLE使用者常用資料字典的查詢使用方法(轉)[@more@]

檢視當前使用者的預設表空間

SQL>select username,default_tablespace from user_users;

檢視當前使用者的角色

SQL>select * from user_role_privs;

檢視當前使用者的系統許可權和表級許可權

SQL>select * from user_sys_privs;

SQL>select * from user_tab_privs;

檢視使用者下所有的表

SQL>select * from user_tables;

1、使用者

檢視當前使用者的預設表空間

SQL>select username,default_tablespace from user_users;

檢視當前使用者的角色

SQL>select * from user_role_privs;

檢視當前使用者的系統許可權和表級許可權

SQL>select * from user_sys_privs;

SQL>select * from user_tab_privs;

顯示當前會話所具有的許可權

SQL>select * from session_privs;

顯示指定使用者所具有的系統許可權

SQL>select * from dba_sys_privs where grantee='GAME';

2、表

檢視使用者下所有的表

SQL>select * from user_tables;

檢視名稱包含log字元的表

SQL>select object_name,object_id from user_objects

where instr(object_name,'LOG')>0;

檢視某表的建立時間

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

檢視某表的大小

SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments

where segment_name=upper('&table_name');

檢視放在ORACLE的記憶體區裡的表

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

3、索引

檢視索引個數和類別

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

檢視索引被索引的欄位

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

檢視索引的大小

SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments

where segment_name=upper('&index_name');

4、序列號

檢視序列號，last_number是當前值

SQL>select * from user_sequences;

5、檢視

檢視檢視的名稱

SQL>select view_name from user_views;

檢視建立檢視的select語句

SQL>set view_name,text_length from user_views;

SQL>set long 2000; 說明：可以根據檢視的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

檢視同義詞的名稱

SQL>select * from user_synonyms;

7、約束條件

檢視某表的約束條件

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、儲存函式和過程

檢視函式和過程的狀態

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

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

檢視函式和過程的原始碼

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