好的，所以我需要将最初在access数据库上使用的查询转换为将在SQL Compact Edition数据库上运行的查询

在这个查询中，我有一个IIF语句（在sql中不起作用）

我查到的所有信息都表明，我应该在需要时用Case替换它

这是我的原始代码：

Select [OrderNumber], [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber],
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime],
[DateImported],  Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee from 
SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee

Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee

Select [OrderNumber],
[CustomerName],
[PO_TAG],
[Shape],
[Size],
[DrawingNumber],
[OrderBuildTime],
[RequiredDateTime],
[LatestStatusTime],
[ExpectedCompletionDateTime],
[DateImported],
Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee 
From SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

这是IIF的声明：

Select [OrderNumber], [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber],
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime],
[DateImported],  Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee from 
SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee

Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee

Select [OrderNumber],
[CustomerName],
[PO_TAG],
[Shape],
[Size],
[DrawingNumber],
[OrderBuildTime],
[RequiredDateTime],
[LatestStatusTime],
[ExpectedCompletionDateTime],
[DateImported],
Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee 
From SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

这是我将IIF语句替换为：

Select [OrderNumber], [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber],
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime],
[DateImported],  Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee from 
SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee

Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee

Select [OrderNumber],
[CustomerName],
[PO_TAG],
[Shape],
[Size],
[DrawingNumber],
[OrderBuildTime],
[RequiredDateTime],
[LatestStatusTime],
[ExpectedCompletionDateTime],
[DateImported],
Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee 
From SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

这就是整个代码体的后记：

Select [OrderNumber], [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber],
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime],
[DateImported],  Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee from 
SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

Sum(IIF([Status] = 'Printed', PanelBuildTime, 0)) AS OrderBuildTimee

Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee

Select [OrderNumber],
[CustomerName],
[PO_TAG],
[Shape],
[Size],
[DrawingNumber],
[OrderBuildTime],
[RequiredDateTime],
[LatestStatusTime],
[ExpectedCompletionDateTime],
[DateImported],
Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee 
From SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]

这是我的新错误消息：

Major Error 0x80040E14, Minor Error 25501
> Select [OrderNumber],
[CustomerName],
[PO_TAG],
[Shape],
[Size],
[DrawingNumber],
[OrderBuildTime],
[RequiredDateTime],
[LatestStatusTime],
[ExpectedCompletionDateTime],
[DateImported],
Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0) AS OrderBuildTimee 
From SteelOrders 
INNER JOIN FinalizedPrintedStickers 
ON 
SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported]
There was an error parsing the query. [ Token line number = 12,Token line offset = 58,Token in 
error = ) ]

案例的正确语法是：
Simple CASE expression: 
CASE input_expression 
     WHEN when_expression THEN result_expression [ ...n ] 
     [ ELSE else_result_expression ] 
END 

Searched CASE expression:
CASE
     WHEN Boolean_expression THEN result_expression [ ...n ] 
     [ ELSE else_result_expression ] 
END

在查询中，您缺少案例的结尾
：
Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0 END) AS OrderBuildTimee 

因此，完整的代码是：
Select [OrderNumber],
  [CustomerName],
  [PO_TAG],
  [Shape],
  [Size],
  [DrawingNumber],
  [OrderBuildTime],
  [RequiredDateTime],
  [LatestStatusTime],
  [ExpectedCompletionDateTime],
  [DateImported],
  Sum(CASE Status WHEN 'Printed' THEN PanelBuildTime ELSE 0 END) AS OrderBuildTimee 
From SteelOrders 
INNER JOIN FinalizedPrintedStickers 
  -- left not supported by sql server ce use substring
  -- ON SteelOrders.OrderNumber = LEFT(FinalizedPrintedStickers.SN,10)
  ON SteelOrders.OrderNumber = substring(FinalizedPrintedStickers.SN, 1, 10)
GROUP BY SteelOrders.OrderNumber, [CustomerName], [PO_TAG], [Shape], [Size], [DrawingNumber], 
[OrderBuildTime], [RequiredDateTime], [LatestStatusTime], [ExpectedCompletionDateTime], 
[DateImported] 

是的，但我收到了一条新的错误消息，因为sqlcompact-\ux-中不支持LEFT。哦，好吧，我将用子字符串替换它
