SQL 左连接语法错误的子查询
SQL sub query with left join syntax error
我有一个查询，我正在尝试 运行，但是当 运行 查询它时，我一直收到语法错误。以下是给我错误的查询：
SELECT A.*, B.Total AS Assigned
FROM (
SELECT tblSkillSets.employeeName AS Employee, tblEvents.eventName AS Event, tblProcesses.ID AS Process, tblProcesses.Priority.Value AS Priority, tblProcesses.minutesPerItem AS Minutes
FROM tblEvents INNER JOIN (tblSkillSets INNER JOIN tblProcesses ON tblSkillSets.eventName = tblProcesses.eventName.Value) ON tblEvents.ID = tblSkillSets.eventName
WHERE tblProcesses.ID=27
) AS A
LEFT JOIN
(
SELECT tblWorkflow.assignedTo AS Employee, Sum(IIf(DateDiff('d',[openedDate],Date())=0,[itemCount]*[minutesPerItem],0)) AS Total
FROM tblProcesses RIGHT JOIN tblWorkflow ON tblProcesses.ID = tblWorkflow.processName
WHERE tblWorkflow.processName=27 AND (tblWorkflow.Status=1 Or tblWorkflow.Status=2)
GROUP BY tblWorkflow.assignedTo
) AS B
ON A.Employee = B.Employee
ORDER BY B.Total, A.Employee
奇怪的是以下查询工作正常：
SELECT Query1.*, Query2.Total AS Assigned
FROM Query1 LEFT JOIN Query2 ON Query1.Employee = Query2.Employee
ORDER BY Query2.Total, Query1.Employee
其中 Query1 是：
SELECT tblSkillSets.employeeName AS Employee, tblEvents.eventName AS Event, tblProcesses.ID AS Process, tblProcesses.Priority.Value AS Priority, tblProcesses.minutesPerItem AS Minutes
FROM tblEvents INNER JOIN (tblSkillSets INNER JOIN tblProcesses ON tblSkillSets.eventName = tblProcesses.eventName.Value) ON tblEvents.ID = tblSkillSets.eventName
WHERE tblProcesses.ID=27;
查询 2 是：
SELECT tblWorkflow.assignedTo AS Employee, Sum(IIf(DateDiff('d',[openedDate],Date())=0,[itemCount]*[minutesPerItem],0)) AS Total
FROM tblProcesses RIGHT JOIN tblWorkflow ON tblProcesses.ID = tblWorkflow.processName
WHERE tblWorkflow.processName=27 AND (tblWorkflow.Status=1 Or tblWorkflow.Status=2)
GROUP BY tblWorkflow.assignedTo;
我所做的只是获取构成 Query1 和 Query2 的代码并将它们用作子查询但是当 运行.
时它不起作用
**编辑：
另一件事是此查询也有效：
SELECT A.*, Query2.Total AS Assigned
FROM (
SELECT tblSkillSets.employeeName AS Employee, tblEvents.eventName AS Event, tblProcesses.ID AS Process, tblProcesses.Priority.Value AS Priority, tblProcesses.minutesPerItem AS Minutes
FROM tblEvents INNER JOIN (tblSkillSets INNER JOIN tblProcesses ON tblSkillSets.eventName = tblProcesses.eventName.Value) ON tblEvents.ID = tblSkillSets.eventName
WHERE tblProcesses.ID=27
) AS A
LEFT JOIN Query2
ON A.Employee = Query2.assignedTo
ORDER BY Query2.Total, A.Employee
这让我认为错误与子查询的左连接或第二个查询本身有关。不过不太确定。
我得到的确切错误是：查询中的语法错误。查询子句不完整。

我明白为什么这不起作用了！虽然它没有解释为什么使用实际的查询对象（Query1 和 Query2）有效，但它解决了我的问题，所以我可以接受。
第二个子查询中的分组导致了问题。我删除了第二个子查询中的分组，然后在最终查询中执行了分组，这是两个子查询的聚合。以下是解决问题的有效查询：
SELECT A.Employee, A.Event, A.Process, A.Priority, A.Minutes, Sum(B.Total) AS Assigned
FROM (
SELECT tblSkillSets.employeeName AS Employee, tblSkillSets.eventName AS Event, tblProcesses.ID AS Process, tblProcesses.Priority.Value AS Priority, tblProcesses.minutesPerItem AS Minutes
FROM tblEvents INNER JOIN (tblSkillSets INNER JOIN tblProcesses ON tblSkillSets.eventName = tblProcesses.eventName.Value) ON tblEvents.ID = tblSkillSets.eventName
WHERE tblProcesses.ID=27
) AS A
LEFT JOIN (
SELECT tblWorkflow.assignedTo, [itemCount]*[minutesPerItem] AS Total
FROM tblProcesses RIGHT JOIN tblWorkflow ON tblProcesses.ID = tblWorkflow.processName
WHERE (tblWorkflow.Status=1 Or tblWorkflow.Status=2)
AND DateDiff('d',[openedDate],Date())=0
) AS B
ON A.Employee = B.assignedTo
GROUP BY A.Employee, A.Event, A.Process, A.Priority, A.Minutes, A.Employee
ORDER BY Sum(B.Total), A.Employee;
所以基本上 Access 无法组合两个子查询，其中一个是聚合而另一个不是。为了解决这个问题，使两个子查询都成为非聚合查询，将它们组合起来，然后在最终查询上执行聚合。
