MySQL脚本触发错误1241

我有下面的脚本，它应该为已经提供的ID数组获取一个价格

但它需要每个ID获得1个价格，而棘手的是，我希望能够有预定的价格更新

---

这意味着它需要采取的价格，我想你的问题在IN条款上

在in子句中选择两个字段

编辑

您需要根据wo_id和Max timestamp_valid自动加入子查询

---

我想你想要这样的东西：

SELECT pp.*, ppf.formula_id, ppf.formula as price2_formula
FROM product_pricing pp LEFT JOIN
     product_price_formulas ppf
     ON pp.formula_id = ppf.formula_id    
WHERE (pp.wo_id, pp.timestamp_valid) IN
          (SELECT pp2.wo_id, MAX(pp2.timestamp_valid)
           FROM product_pricing pp2
           WHERE pp2.wo_id IN ('015724', '028791', '015712', '015715', '015717', '039750', '028791') AND
                pp2.timestamp_valid <= UTC_TIMESTAMP
          );

您可以将product_pricing和最新有效的_时间戳记录的派生结果集结合起来

如果我们暂时忽略产品定价公式表，因为您没有将其包含在样本数据和结果中

SELECT 
p.`wo_id`,
p.`price` AS price2,
p.`timestamp_valid`
FROM `product_pricing` p
JOIN (SELECT wo_id, MAX(timestamp_valid) AS max_valid_ts
      FROM `product_pricing`
      WHERE `timestamp_valid` <= UTC_TIMESTAMP
      GROUP BY wo_id) d
ON (d.wo_id = p.wo_id AND d.max_valid_ts = p.timestamp_valid)
WHERE p.`wo_id` IN (015724, 028791);

试一试

嗯，是的，它是这样工作的，但是…它返回每个ID的多个价格。它只需要返回1，这是产品定价。时间戳有效。您可以提供一些示例数据和您的预期结果，这将是有帮助的：添加。请看一下这本书question@Borsn抱歉，回复晚了，编辑愿望可以帮助您：它返回每个id的所有值。而不是像在想要的输出中那样通过时间戳过滤掉它。MAX在这种情况下做了什么？您似乎只是在选择公式。如何添加原始SELECT中的所有其他行？@Borsn。您可以在“选择”菜单中列出它们。我把它短路到了。
