Oracle根據主鍵獲取對應表spa

select *
  from user_constraints a, USER_CONS_COLUMNS b
 where a.CONSTRAINT_TYPE = 'P'
   and a. constraint_name = b.constraint_name
   and a.constraint_name = 'PK151'; --根據主鍵名查詢表(PK151爲主鍵名稱

 

Oracle根據外鍵獲取相關表code

select *
  from user_constraints cc
 where cc.r_constraint_name in
       (select c.r_constraint_name
          from user_constraints c
         where c.constraint_type = 'R'
           and c.constraint_name = 'REFB_BJB125') --根據外鍵獲取相關的表(REFB_BJB125爲外鍵名稱
