Question

我有以下查询在我的测试盒上运行正常但在我的生产盒上不起作用。有什么问题？

SELECT 
    *,
    round(priceperkm * IFNULL(KMPlanned, projects.KM),
            4) AS NEWVALUE,
    round(PRICE * IFNULL(KMPlanned, projects.KM),
            2) AS TotalPriceForItem,
    SUM(((abs(FSP - LSP) + 1) * SI) / 1000) AS KM_Completed,
    round(SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE,
            2) AS TotalPrice,
    round((SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE) / (PRICE * IFNULL(KMPlanned, projects.KM)) * 100,
            2) AS TotalPercent
FROM
    hdb.projects
        join
    biditems ON projects.id = biditems.project_id
        join
    lookupprocess ON biditems.ITEMID = lookupprocess.biditems_id
        left join
    jobsprocesscomplete ON lookupprocess.ID = lookupprocess_id
        left join
    detailsseismic ON jobsprocesscomplete.JOBNO = detailsseismic.JOBNO
where
    projects.PROJID = 1402013
        and lookupprocess.ID = 13138

错误：

更新两台服务器都给出了相同的结果 SELECT @@ GLOBAL.sql_mode; + ------------------- + | @@ GLOBAL.sql_mode | + ------------------- + | | + ------------------- + 1行（0.00秒）

mysql> SELECT @@SESSION.sql_mode;

如果我在查询结束时添加group by lookupprocess.ID会发生什么。它会返回相同的结果吗？

Answer 1

您的select子句同时具有列和聚合函数（sum()）。这会将查询转换为只返回一行的聚合查询，这可能是也可能不是您想要的。（我怀疑你确实想要group by 某些东西。）

无论如何，这都使用MySQL扩展。扩展由系统变量ONLY_FULL_GROUP_BY控制。启用此选项后，将应用ANSI规则。阅读它here！。

您看到的行为表明在生产服务器上启用了ONLY_FULL_GROUP_BY，但在开发服务器上没有启用{{1}}。您应该启用它或在两者中禁用它。

Answer 2

我将两台服务器更新为存储库中可用的最新mysql版本。受影响的服务器有旧版本，我相信它不支持sql语句。

mysql查询在不同的服务器上给出不同的结果
