  0、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 wner=user and name=upper('&plsql_name');
