Oracle> Oracle的多表更新要求比较严格,所以有的时候不是很好写,我们可以试试Oracle的游标 update ( select t.charger_id_ new_charger_id_ from t_cus_year_status t left join t_customer_infos cus on cus.id_ = t.cus_id_ where.... ) n set n.new_charger_id_ =6;
复制代码 代码如下:
mysql> update t_cus_year_status t left join t_customer_infos cus on cus.id_ = t.cus_id_ set t.charger_id_ =6 where......;
