Mysql 多个选择，带“选择”；“联合所有人”；不起作用

它们都很好。

我在你的查询中发现了很多问题

对于union和union，两个查询选择中的所有列数都必须相同，但在两个查询中并没有相同的列数 列的第一个选择编号为7

     select
     department as "Delegación",
     company as Compañía,
     config as "Configuración Vehículos",
     docs as "Documentos Vehículos",
     count(distinct idClientTruck) as vehículos,
     sum(ko) as "Doc. incorrectos Vehículos",
     round(sum(ko)/(docs*count(distinct idClientTruck))*100) as "% Docs. Vehículos"

及

其中，列的第二个选择编号为5

    select
    config as "Configuración Conductores",
    docs as "Documentos Conductores",
    count(distinct idDriver) as Conductores,
    sum(ko) as "Doc. incorrectos Conductores",
    round(sum(ko)/(docs*count(distinct idDriver))*100) as "% Docs. Conductores"

按部门、公司、配置、idWidocConfigGroup分组

需要将其放置在正确的位置它应该位于别名x之后

删除不必要的别名，如d和t

---

将

）x）d...

更改为

）x组（按部门、公司、配置、idWidocConfigGroup）

相同的错误，即使我在“）”之后删除了“d”，则此错误显示为：错误代码：1054。“字段列表”中的未知列“idClientTruck”要聚合什么？在进行聚合的每个语句中，都必须添加一个group by。你能为预期的结果添加一个简短的例子吗？Ramon，你已经写了两次相同的查询了。另外，请检查@Zaynul Abadin Tuhin的答案，他提出了一些很好的建议。这不是同一个查询。如果我删除“d”和“t”，错误代码：1248。每个派生表都必须有自己的别名
