多个选择语句的问题答案

【问题标题】：Issue with Multiple select statements多个选择语句的问题
【发布时间】：2015-11-17 09:14:15
【问题描述】：

我在查询中使用多个选择语句和案例来获取结果。请查看我正在尝试解决的查询。但它给了我一个聚合函数的错误。我想做的是，我有 3 个预算标准，结果应该是这样的。它们是：

Budget 2015
Budget Jan-july2015
Budget July-dec2015

在第一个字段中，我将获得整个 2015 年的预算，在第二个字段中，我希望将来自 july-dec2015 的预算费用作为“当前预算”，在第三个字段中，jan-july2015 和 july-dec2015 的预算应添加为“累积”费用”。

SELECT CASE WHEN T1.[AcctName] LIKE '%Salaries%' THEN 'Salaries'
            WHEN T1.[AcctName] LIKE '%Travel%' THEN 'Travel'
            WHEN T1.[AcctName] LIKE '%Supplies%' THEN 'Supplies'
            WHEN T1.[AcctName] LIKE '%Consultants%' THEN 'Consultants'
            WHEN T1.[AcctName] LIKE '%Patient%' THEN 'Patient Care'
            WHEN T1.[AcctName] LIKE '%Equipment%' THEN 'Equipments' 
            WHEN T1.[AcctName] LIKE '%Expense%' THEN 'Other Expenses' 
            WHEN T1.[AcctName] LIKE '%Alteration%' THEN 'Alterations/Renovations' ELSE 'Alterations/Renovations' END,
    SUM(T0.[DebLTotal]/85) AS buget , (Select sum(T0.[CrdRLTotal]/85) where T2.[Name] = 'July-Dec2015' ) as 'CurrentBudget',
    (select sum(T0.[CrdRLTotal]/85) + 'CurrentBudget' where T2.[Name] = 'jan-july2015') as 'Cummulative' 
FROM OBGT 
T0 INNER JOIN OACT T1 ON T0.[AcctCode] = T1.[AcctCode] INNER JOIN OBGS T2 ON T0.[Instance] = T2.[AbsId] where T2.[Name] = 'Main Budget 2015'
GROUP BY CASE WHEN T1.[AcctName] LIKE '%Salaries%' THEN 'Salaries'
              WHEN T1.[AcctName] LIKE '%Travel%' THEN 'Travel'
              WHEN T1.[AcctName] LIKE '%Supplies%' THEN 'Supplies'
              WHEN T1.[AcctName] LIKE '%Consultants%' THEN 'Consultants' 
              WHEN T1.[AcctName] LIKE '%Patient%' THEN 'Patient Care' 
              WHEN T1.[AcctName] LIKE '%Equipment%' THEN 'Equipments'
              WHEN T1.[AcctName] LIKE '%Expense%' THEN 'Other Expenses'
              WHEN T1.[AcctName] LIKE '%Alteration%' THEN 'Alterations/Renovations' ELSE 'Alterations/Renovations' END

我不知道如何获取所有必需的字段。

【问题讨论】：

使用派生表或 cte 来简化代码。（即避免两次编写那个巨大的 CASE。）
你说你得到一个错误，那是什么错误？
@jarlh 你能帮我从这个查询中获得所需的结果吗，或者你有另一个查询来获得所需的结果
@TZHX 列 'OBGS.Name' 在选择列表中无效，因为它不包含在聚合函数或 GROUP BY 子句中。
您有明确的错误消息 - 您能否将查询更改为“将 OBGS.Name 包含到聚合函数或 GROUP BY 子句中”？

【解决方案1】：

这不是答案，只是为了说明如何使用 t1 的派生表以更短的形式编写代码。

SELECT T1.[AcctName],
       SUM(T0.[DebLTotal]/85) AS buget,
       (Select sum(T0.[CrdRLTotal]/85) where T2.[Name] = 'July-Dec2015' ) as 'CurrentBudget',
       (select sum(T0.[CrdRLTotal]/85) + 'CurrentBudget' where T2.[Name] = 'jan-july2015') as 'Cummulative' 
FROM OBGT T0
INNER JOIN
    (
    SELECT CASE WHEN T1.[AcctName] LIKE '%Salaries%' THEN 'Salaries'
                WHEN T1.[AcctName] LIKE '%Travel%' THEN 'Travel'
                WHEN T1.[AcctName] LIKE '%Supplies%' THEN 'Supplies'
                WHEN T1.[AcctName] LIKE '%Consultants%' THEN 'Consultants'
                WHEN T1.[AcctName] LIKE '%Patient%' THEN 'Patient Care'
                WHEN T1.[AcctName] LIKE '%Equipment%' THEN 'Equipments' 
                WHEN T1.[AcctName] LIKE '%Expense%' THEN 'Other Expenses' 
                WHEN T1.[AcctName] LIKE '%Alteration%' THEN 'Alterations/Renovations'
                ELSE 'Alterations/Renovations'
           END as [AcctName],
           [AcctCode]
    from OACT
    ) as T1 ON T0.[AcctCode] = T1.[AcctCode]
INNER JOIN OBGS T2 ON T0.[Instance] = T2.[AbsId]
where T2.[Name] = 'Main Budget 2015'
GROUP BY T1.[AcctName]

【讨论】：

我之前试过这个代码。它给了我无法绑定多部分标识符“T1.AcctName”。错误..
如果你知道答案，请告诉我。
