加入两个查询或工会/联盟全部

Question

我从下面的代码创建了一个联合。我不确定这是我想要的。最上面的部分分成较小的细节。它通过engProf和种族来衡量学生的数量，按学校，等级，考试分数。第二个查询给出了按学生，学校，年级和考试分列的学生总数。回到学校的二年级学生总数x进行了数学测试，x学生参加了阅读测试。一个将是另一个的更高层次的总结。我想将它们结合在一起以便在报告中使用一个数据集。有什么建议么。我尝试了一个联盟，并不确定这是否是最好的解决方案。

Answer 1

这是一招一个相当普遍的做法...添加在订单或水平柱得到正确的顺序结果。对于您正在分组的项目没有空值，因为您无法正确订购。下面是一个例子，我列出的班级学生和总数：

SELECT class, student_name, count 
    FROM 
    (
    SELECT class, student_name, 0 as count, 1 as ord 
    FROM classlist 
    UNION ALL 
    SELECT class, '' as student_name, count() as count, 2 as ord 
    FROM classlist 
    GROUP BY class 
    ) T 
    ORDER BY class, ord, student_name 

Answer 2

难道你不想只剩下外部加入2吗？ 左桌有细粒（更多细节）。

您可以使用CTE。
