Question

所以首先我的mysql表定义如下：

订单（333000+条记录）

orders_id(PK), 
customerName, 
CompanyName, 
Status, 
shipping_no, 
shipping_module, 
tracking_no, 
orders_status, 
date_purchased..

Order_status （70条记录）

orders_status_id(pk),
language_id,
orders_status_name

orders_status_history （2220000+条记录）

  `orders_status_history_id` int(11) 
  `orders_id` int(11)
  `orders_status_id` int(5) 
  PRIMARY KEY  (`orders_status_history_id`)

orders_status_history 表包含有关每个订单的不同状态

  `orders_status_id` int(11)
  `orders_status_name` varchar(32)
  PRIMARY KEY (`orders_status_id`,`language_id`)

所以我想要得到的是下面描述的所有三个选项：

订单必须shipping_module pickup_pickup或pickup2_pickup2
orders_status_history.orders_status_id必须具有以下状态7,21,34,40
但orders_status_history.orders_status_id必须没有以下状态33,53

解释问题：假设有10个订单，他们在生命中的某个时间有以下状态：

[7,34,41,48]
[20,40,34,57,14,25]
[53,7,40,5]
[41,25,4]
[1,2,3,4]
[34,4,33,53,7]
[4,21,31,7,8]
[78,15,45,40]
[53,40,31,21,7]
[33,74,54,7,22]

所以我要提取的订单是1,2,7,8因为这个订单包含7,31,21或40而不是53,33

我尝试过以下查询：

1）

SELECT * 
FROM orders AS o, orders_status_history AS osh
WHERE (
       o.shipping_module LIKE  '%pickup_pickup%'
       OR o.shipping_module LIKE  '%pickup2_pickup2%'
   )
AND o.orders_id = osh.orders_id
AND osh.orders_status_id
IN ( 7, 21, 31, 40 ) AND osh.orders_status_id
NOT IN (33, 53)

此查询可以正常运行，但它可以获得所有结果（1200条记录），但它没有过滤3选项

2）。

SELECT * 
FROM orders AS o, orders_status_history AS osh
WHERE (
       o.shipping_module LIKE  '%pickup_pickup%'
       OR o.shipping_module LIKE  '%pickup2_pickup2%'
   )
AND o.orders_id = osh.orders_id
AND osh.orders_status_id IN (7, 21, 31, 40) 
AND osh.orders_status_id != 33
AND osh.orders_status_id != 53

它也像以前一样工作，没有过滤第3个选项

3。）

SELECT * 
FROM orders AS o, orders_status_history AS osh
WHERE (
       o.shipping_module LIKE  '%pickup_pickup%'
       OR o.shipping_module LIKE  '%pickup2_pickup2%'
   )
AND o.orders_id = osh.orders_id
AND osh.orders_status_id IN (7, 21, 31, 40) 
AND osh.orders_status_id NOT IN (
                                 SELECT so.orders_id 
                                 FROM orders AS so, orders_status_history AS sosh
                                 WHERE (
                                        so.shipping_module LIKE  '%pickup_pickup%'
                                        OR so.shipping_module LIKE  '%pickup2_pickup2%'
                                        )
                                 AND sosh.orders_status_id != 33
                             )

此查询花费了太多时间来执行并且没有执行

4。）

SELECT * 
FROM orders AS o, orders_status_history AS osh
WHERE (
       o.shipping_module LIKE  '%pickup_pickup%'
       OR o.shipping_module LIKE  '%pickup2_pickup2%'
   )
AND o.orders_id = osh.orders_id
AND osh.orders_status_id = 7
AND osh.orders_status_id = 21
AND osh.orders_status_id = 31
AND osh.orders_status_id = 40
AND osh.orders_status_id != 33
AND osh.orders_status_id != 53

此查询首先作为查询未过滤第3个选项

所以后来我用php试试了

$sql = "SELECT o.orders_id, osh.orders_status_history_id
        FROM 
            orders AS o, 
            orders_status_history AS osh
        WHERE ( 
            o.shipping_module LIKE  '%pickup_pickup%'
            OR o.shipping_module LIKE  '%pickup2_pickup2%'
           )
        AND o.orders_id = osh.orders_id
        AND osh.orders_status_id IN (7, 21, 31, 40) 
        AND osh.orders_status_id != 33
        AND osh.orders_status_id != 53";
$sql    = mysql_query($sql);
while ($row = mysql_fetch_array($sql)){
    $row["orders_id"]);
    if(getOrderStatus($row["orders_id"]))
        echo "<br/>".$row["orders_id"];
}

function getOrderStatus($order){
    $sql    = "SELECT orders_status_id FROM orders_status_history WHERE orders_id = ".$order;
    echo "<br/> Sql Query : ".$sql;
     $sql = mysql_query($sql);
     while ($status     = mysql_fetch_array($sql))
       if((int)$status["orders_status_id"] == 33 || (int)$status["orders_status_id"] == 53)
            return false;
    return true;
}

此代码占用的时间超过30米。我set_time_limit(0);

注意：我只能使用Mysql_ *，因为我们的php版本是4.9

Answer 1

以下是获取符合条件的订单的一种方法：

SELECT o.orders_id
FROM orders o JOIN
     orders_status_history osh
     ON o.orders_id = osh.orders_id
WHERE (o.shipping_module LIKE  '%pickup_pickup%' OR
       o.shipping_module LIKE  '%pickup2_pickup2%'
      ) AND
      osh.orders_status_id IN (7, 21, 31, 40, 33, 53)
GROUP BY o.orders_id
HAVING SUM( osh.orders_status_id IN (33, 53) ) = 0;

WHERE仅选择您关注的状态。 HAVING确保您没有最后两个。

如果您需要订单或订单行的详细信息，则需要将这些表重新加入。

Mysql - 花费太多时间来执行查询
