   and c.OWNER = SYS_CONTEXT('USERENV', 'CURRENT_SCHEMA')
   and c.constraint_type = 'R'
   and p.CONSTRAINT_NAME = c.R_CONSTRAINT_NAME

oracle中查询该表中的外键来源于哪些表的SQL语句：

select cl.table_name
  from user_cons_columns cl
  left join user_constraints c
    on cl.constraint_name = c.r_constraint_name
 where c.constraint_type = 'R'
