报错如下
查出主表少的数据
select * from GUPROPOSALCLAUSES t,GUPROPOSALMAIN tt where t.PROPOSALNO = tt.PROPOSALNO(+) and tt.PROPOSALNO is null
然后删除子表中多的那些数据,当然也可以从源库找到主表缺少的数据,然后添加进来
delete from GUPOLICYCOPYPAYMENTPLANDETAIL where policyno='U604131516000277';
下面是一个找出各种主外键关系的表
select (select a.table_name from user_constraints a where a.constraint_name = c.r_constraint_name) 主表表名, c.r_constraint_name 主表主键键约束名, c.table_name 从表表名, c.constraint_name 从表外键约束名,c.* from user_constraints c where c.constraint_type = 'R' and c.constraint_name='FK_GUPOLICY_R56';
