Question

我正在尝试从不同的表中加入不同的数据类型。我以为我的语法正确但显然我一定做错了。

语法错误表示表达式中的类型不匹配，所以我确定我没有正确转换数据类型

这是我的加入

SELECT CLng([Inventory].ItemID) AS [Item#],
Sum([Invoice].Quantity) AS [Order QTY] 
FROM [Invoice] INNER JOIN [Inventory] ON [Invoice].ItemID = CLng([Inventory].ItemID)
WHERE ((([Invoice].OrderNumber) BETWEEN 1 And 23))
GROUP BY CLng([Inventory].ItemID);

Answer 1

为什么在里面（）？尝试删除并将数字转换为str

 SELECT CLng([Inventory].ItemID) AS [Item#],
 Sum([Invoice].Quantity) AS [Order QTY] 
 FROM [Invoice] INNER JOIN [Inventory] ON  Str ( [Invoice].ItemID)  =  [Inventory].ItemID
 WHERE [Invoice].OrderNumber) BETWEEN 1 And 23
 GROUP BY CLng([Inventory].ItemID);

或

  SELECT CLng([Inventory].ItemID) AS [Item#],
 Sum([Invoice].Quantity) AS [Order QTY] 
 FROM [Invoice] INNER JOIN [Inventory] ON CLng( Str ( [Invoice].ItemID))  = CLng( [Inventory].ItemID)
 WHERE [Invoice].OrderNumber) BETWEEN 1 And 23
 GROUP BY CLng([Inventory].ItemID);
