Question

我有一个包含9个变量的MS SQL表：

  Table (var1, var2, var3 ... var9)

我写了以下查询：

  SELECT var1, COUNT(var10)
  FROM (
     SELECT *, (CASE WHEN ABS(var1 - var2) >= 1 THEN 1 ELSE 0 END) as var10
        FROM DB.Table_Name
        GROUP BY var 3
        ORDER BY var 3
       )

我收到错误：

ORDER BY子句在视图，内联函数中派生无效表，子查询和公用表表达式，除非TOP，OFFSET 或者也指定了FOR XML。

我不知道我在这里做错了什么......

我想要的是：

根据条件在表中再添加一个变量Var10：

 (CASE WHEN ABS(var1 - var2) >= 1 THEN 1 ELSE 0 END)

然后计算：

The counts of Var10 Grouped By Var3 and in descending order

有人可以帮忙吗？

示例数据：

Var1    Var2    Var3    Var4    Var5    Var6    Var7    Var8    Var9

假设这是用于创建Var10的示例查询：

Var3                Var10
ABC123BCUSUS130351  1
ABC123BCUSUS130352  1
ABC123BCUSUS130353  1
ABC123BCUSUS130353  1
ABC123BCUSUS130356  2
ABC123BCUSUS130352  1
ABC123BCUSUS130355  2
ABC123BCUSUS130354  3
ABC123BCUSUS130356  1
ABC123BCUSUS130356  0
ABC123BCUSUS130354  1
ABC123BCUSUS130355  3
ABC123BCUSUS130351  1
ABC123BCUSUS130352  1
ABC123BCUSUS130352  2
ABC123BCUSUS130356  1
ABC123BCUSUS130356  1
ABC123BCUSUS130356  4
ABC123BCUSUS130356  2
ABC123BCUSUS130356  2
ABC123BCUSUS130356  3
ABC123BCUSUS130356  1

然后最终输出应该如下：

Var3                Count(Var10)
ABC123BCUSUS130356    10
ABC123BCUSUS130352    5
ABC123BCUSUS130355    5
ABC123BCUSUS130354    4
ABC123BCUSUS130351    2
ABC123BCUSUS130353    2

Answer 1

如果我理解你的要求正确，你可以寻找这个

SELECT var3, SUM(var10)
FROM (
    SELECT var3,
           (CASE WHEN ABS(var1 - var2) >= 1 THEN 1 ELSE 0 END) as var10
    FROM DB.Table_Name
)M
GROUP BY var3
ORDER BY var3

Answer 2

你根本不需要子查询。我相信你打算：

SELECT var3,
       SUM(CASE WHEN ABS(var1 - var2) >= 1 THEN 1 ELSE 0 END) as var10
FROM DB.Table_Name
GROUP BY var3
ORDER BY var3;

count上的{p> var10没有意义或产生您真正想要的结果。

多级选择查询
