无法绑定多部分标识符 'T1.[AcctName]'

Question

我正在尝试从写入的查询中获取结果 below.from 我遇到了错误

The multi-part identifier "T1.AcctName" could not be bound.

我不知道为什么要这样。请帮忙。

SELECT T1.[AcctName],
       SUM(T0.[DebLTotal]/85) AS buget
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]

您可以删除子查询中的别名：

SELECT T1.[AcctName],
       SUM(T0.[DebLTotal]/85) AS buget
FROM OBGT T0
INNER JOIN
    (
    SELECT CASE WHEN [AcctName] LIKE '%Salaries%' THEN 'Salaries'
                WHEN [AcctName] LIKE '%Travel%' THEN 'Travel'
                WHEN [AcctName] LIKE '%Supplies%' THEN 'Supplies'
                WHEN [AcctName] LIKE '%Consultants%' THEN 'Consultants'
                WHEN [AcctName] LIKE '%Patient%' THEN 'Patient Care'
                WHEN [AcctName] LIKE '%Equipment%' THEN 'Equipments' 
                WHEN [AcctName] LIKE '%Expense%' THEN 'Other Expenses' 
                WHEN [AcctName] LIKE '%Alteration%' THEN 'Alterations/Renovations'
                ELSE 'Alterations/Renovations'
           END as [AcctName],
           [AcctCode]
    from OAC
    ) 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];

重点是别名 T1 在子查询外部定义，因此在内部不可见。

或者你可以在里面添加别名，比如：

SELECT T3.[AcctName],
       SUM(T0.[DebLTotal]/85) AS buget
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
    ) as T3 ON T0.[AcctCode] = T3.[AcctCode]
INNER JOIN OBGS T2 ON T0.[Instance] = T2.[AbsId]
where T2.[Name] = 'Main Budget 2015'
GROUP BY T3.[AcctName]
