mysql查询在不同的服务器上给出不同的结果

Question

我有以下查询，它在我的测试箱上运行良好，但在我的生产箱上不起作用。有什么问题吗？

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

更新下面两个服务器给出相同的结果 选择@@GLOBAL.sql_mode； +--------------------+ | @@GLOBAL.sql_mode | +--------------------+ | | +--------------------+ 一组 1 行(0.00 秒)

mysql> SELECT @@SESSION.sql_mode;
+--------------------+
| @@SESSION.sql_mode |
+--------------------+
|                    | 
+--------------------+
1 row in set (0.00 sec)

mysql> show variables like 'sql_mode'
    -> ;
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| sql_mode      |       | 
+---------------+-------+

如果我在查询末尾添加group bylookupprocess.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())。这会将查询变成只返回一行的聚合查询，这可能是也可能不是您想要的。 (我怀疑您确实想要group by某物。)

无论如何，这都使用 MySQL 扩展。该扩展由系统变量 ONLY_FULL_GROUP_BY 控制。启用此功能后，将应用 ANSI 规则。了解它 here !.

您所看到的行为表明，在生产服务器上启用了 ONLY_FULL_GROUP_BY，但在开发服务器上未启用。您应该在两者中启用它或禁用它。
