Mysql 对多个表使用NOT IN语句的简化方法

如何简化此查询？不幸的是，这不起作用

$Query = mysqli_query($conn, "SELECT * FROM order_number where trans_id NOT IN (SELECT order_no from billing)
                                       AND NOT IN(SELECT order_no from pending)
                                       AND NOT IN(SELECT order_no from on_process)
                                       AND NOT IN(SELECT order_no from finished)");

还有别的办法吗？我正在尝试打印trans_id行，如果它不在计费、挂起、在_进程中且已完成

SELECT * FROM order_number 
where trans_id NOT IN 
(
   SELECT order_no from billing
   union 
   SELECT order_no from pending
   union 
   SELECT order_no from on_process
   union
   SELECT order_no from finished
)

或者当你尝试的时候

SELECT * FROM order_number 
where trans_id NOT IN (SELECT order_no from billing)
  AND trans_id NOT IN (SELECT order_no from pending)
  AND trans_id NOT IN (SELECT order_no from on_process)
  AND trans_id NOT IN (SELECT order_no from finished)

或者当你尝试的时候

SELECT * FROM order_number 
where trans_id NOT IN (SELECT order_no from billing)
  AND trans_id NOT IN (SELECT order_no from pending)
  AND trans_id NOT IN (SELECT order_no from on_process)
  AND trans_id NOT IN (SELECT order_no from finished)

或者当你尝试的时候

SELECT * FROM order_number 
where trans_id NOT IN (SELECT order_no from billing)
  AND trans_id NOT IN (SELECT order_no from pending)
  AND trans_id NOT IN (SELECT order_no from on_process)
  AND trans_id NOT IN (SELECT order_no from finished)

或者当你尝试的时候

SELECT * FROM order_number 
where trans_id NOT IN (SELECT order_no from billing)
  AND trans_id NOT IN (SELECT order_no from pending)
  AND trans_id NOT IN (SELECT order_no from on_process)
  AND trans_id NOT IN (SELECT order_no from finished)

您可以在表上进行左联接，并筛选出没有匹配记录的记录：

select
  n.*
from
  order_number n
  left join billing b on b.order_no = n.trans_id
  left join pending p on p.order_no = n.trans_id
  left join on_process o on o.order_no = n.trans_id
  left join finished f on f.order_no = n.trans_id
where
  b.order_no is null and
  p.order_no is null and
  o.order_no is null and
  f.order_no is null

没有理由“简化”查询。如果在四个子查询中的表上有适当的索引，它应该是非常有效的。如果任何表中的

orderno

可能为

NULL

，那么我建议使用

notexists

：

SELECT *
FROM order_number  o
WHERE NOT EXISTS (select order_no from billing where b.order_no = o.trans_id) AND
      NOT EXISTS (select order_no from pending p where p.order_no = o.trans_id) AND
      NOT EXISTS (select order_no from on_process op where op.order_no = o.trans_id) AND
      NOT EXISTS (select order_no from finished f where f.order_no = o.trans_id);

正确的索引是：

计费（订单号）

，

挂起（订单号）

，

完成（订单号）

，以及

关于流程（订单号）
