Sql 为什么仅在使用“选择为”时才获得“输入参数值”

这个问题

SELECT P2.ID, P2.Storenum, [Periods_2013-2014].[PeriodDate] AS [OpenFromDate],
  P2.[Open From Day], P2.[Open From Time], P2.[Open To Day], 
  P2.[Open To Time]
FROM [Periods_2013-2014] 
INNER JOIN [tblOpenCloseTimes] AS P2 ON [Periods_2013-2014].[Day]=P2.[Open From Day]
WHERE ((([Periods_2013-2014].Day)=P2.[Open From Day] 
  AND P2.Storenum ="43010605" 
  AND [Periods_2013-2014].Period = "4"))

SELECT T2.Storenum, T2.[PeriodDate] AS [Open From Date], T2.[Open From Day], 
T2.[Open From Time], T1.[PeriodDate] AS [Open To Date], T2.[Open To Day], 
T2.[Open To Time]
FROM [Periods_2013-2014] AS T1, 
(SELECT P2.Storenum, P1.[PeriodDate],  P2.[Open From Day], P2.[Open From Time], 
P2.[Open To Day], P2.[Open To Time]
FROM [Periods_2013-2014] AS P1 INNER JOIN tblOpenCloseTimes AS P2 
ON P1.[Day]=P2.[Open From Day]
WHERE (((P1.Day)=P2.[Open From Day] 
   AND P2.Storenum ="43010605" 
   AND P1.Period = "4"))
ORDER BY P1.[PeriodDate]) AS T2
WHERE T1.[Day]=T2.[Open To Day]
AND T1.[PeriodDate]>=T2.[PeriodDate] 
AND T1.[PeriodDate] - T2.[PeriodDate] <7
ORDER BY P1.[PeriodDate];

结果是输入一个参数值，Query1.PeriodDate作为请求的参数，而如果我只从第一行删除as[OpenFromDate]，查询将运行得很好。如果我将[Periods_2013-2014]表别名为P1，情况也一样。这不会是一个问题，除非我需要堆叠查询以获得两次PeriodDate字段。我做错了什么

更新：此查询

SELECT P2.ID, P2.Storenum, [Periods_2013-2014].[PeriodDate] AS [OpenFromDate],
  P2.[Open From Day], P2.[Open From Time], P2.[Open To Day], 
  P2.[Open To Time]
FROM [Periods_2013-2014] 
INNER JOIN [tblOpenCloseTimes] AS P2 ON [Periods_2013-2014].[Day]=P2.[Open From Day]
WHERE ((([Periods_2013-2014].Day)=P2.[Open From Day] 
  AND P2.Storenum ="43010605" 
  AND [Periods_2013-2014].Period = "4"))

SELECT T2.Storenum, T2.[PeriodDate] AS [Open From Date], T2.[Open From Day], 
T2.[Open From Time], T1.[PeriodDate] AS [Open To Date], T2.[Open To Day], 
T2.[Open To Time]
FROM [Periods_2013-2014] AS T1, 
(SELECT P2.Storenum, P1.[PeriodDate],  P2.[Open From Day], P2.[Open From Time], 
P2.[Open To Day], P2.[Open To Time]
FROM [Periods_2013-2014] AS P1 INNER JOIN tblOpenCloseTimes AS P2 
ON P1.[Day]=P2.[Open From Day]
WHERE (((P1.Day)=P2.[Open From Day] 
   AND P2.Storenum ="43010605" 
   AND P1.Period = "4"))
ORDER BY P1.[PeriodDate]) AS T2
WHERE T1.[Day]=T2.[Open To Day]
AND T1.[PeriodDate]>=T2.[PeriodDate] 
AND T1.[PeriodDate] - T2.[PeriodDate] <7
ORDER BY P1.[PeriodDate];

现在我已经从属性表中删除了ORDERBY子句，效果非常好

Access不允许您在查询中使用字段别名。所以，我想问题在于你的Where条款

请尝试删除名称：P2并使用完整的表名，以便语句看起来像：

SELECT [tblOpenCloseTimes].ID, [tblOpenCloseTimes].Storenum, [Periods_2013-2014].[PeriodDate] AS [OpenFromDate],
  [tblOpenCloseTimes].[Open From Day], [tblOpenCloseTimes].[Open From Time], [tblOpenCloseTimes].[Open To Day], 
  [tblOpenCloseTimes].[Open To Time]
FROM [Periods_2013-2014] 
INNER JOIN [tblOpenCloseTimes] ON [Periods_2013-2014].[Day]=[tblOpenCloseTimes].[Open From Day]
WHERE ((([Periods_2013-2014].Day)=[tblOpenCloseTimes].[Open From Day] 
  AND [tblOpenCloseTimes].Storenum ="43010605" 
  AND [Periods_2013-2014].Period = "4"))

我想知道为什么其中一个表使用别名，而另一个表不使用别名。为列名称使用别名是可以的。但是，Where子句中不应使用这些别名

这是MS access查询吗？只是想一想，MS access有时会在SQL编辑器中抛出这种奇怪的错误，即使您对SQL进行了更改，它仍会看到旧语法，并会抛出一条与您看到的错误消息类似的错误消息。尝试创建一个新查询并将语法粘贴到该查询中。如果我无意中拼错了正在查询的表上的字段名，或者该字段完全不存在，我也会经常遇到此错误消息。@TomFoale-请阅读下面关于在属性表中清除order by参数的注释。这可能是我上面描述的奇怪错误的原因，现在我知道如何在将来修复它。谢谢。我用方括号中的完整表名替换了所有别名。相同的条件下也会发生相同的错误-仅当我对您的列使用AS子句时。请在整个查询中尝试一个不使用任何别名的查询，然后尝试仅对列使用别名。我保存并关闭了查询，然后重新打开它，现在它总是要求参数值。我复制并粘贴了您的查询，该查询始终要求参数值。使用文档管理器会给出：OrderBy:[Query1]。[PeriodDate]OrderByOn:False。Periods_2013-2014表格的表格结构为ID-自动编号、Period-Text、Week-Text、Week No-Text、Day-Text、PeriodDate-Date/Time。我在查询的属性表中通过查询1:PeriodDate找到了订单。我删除了它，现在查询运行得很好，不管有没有AS子句。谢谢你的帮助，这让我有一阵子感到难堪。
