Question

我收到一条错误，指出无法识别等号。我总是在Access中测试我的代码以确保它能够正常工作。有谁知道为什么会这样？

代码：

SELECT SUM(
                       IIf(TransactionType = 'Cash', 
                       TotalPrice, 0)
           ) AS TotalCash, 
       SUM(
                       IIf(TransactionType = 'Credit', 
                       TotalPrice, 0)
           ) AS TotalCredit,
       SUM(
                       IIf(TransactionType = 'Check', 
                       TotalPrice, 0)
           ) AS TotalCheck,
       SUM(
                       IIf(TransactionType = 'Multiple', 
                       IIf(MultiCash = 0, 
                        0, MultiCash), 0)
           ) AS MultipleCash,
       SUM(
                       IIf(TransactionType = 'Multiple', 
                       IIf(MultiCredit= 0, 
                        0, MultiCredit), 0)
           ) AS MultipleCredit,
       SUM(
                       IIf(TransactionType = 'Multiple', 
                       IIf(MultiCheck = 0, 
                        0, MultiCheck), 0)
           ) AS MultipleCheck

FROM  RECEIPT 

WHERE ReceiptDate BETWEEN ? AND ?

错误：

Generated SELECT statement.
   Error in list of function arguments: '=' not recongized.
   Unable to parse query text.

编辑：

让我告诉你我想做什么而不只是发布代码。这可能是解决这个问题的另一个简单方法。所以我想从vb.net中的报告查看器中提取报告，告诉我在特定日期之间使用的投标。

实施例。

1/20/2013
Transaction Type                 Amount
Cash                             $100.00
Check                            $300.00
Credit                           $1,000.00
MultiCash                        $1,500.00
MultiCheck                       $1,500.00
MultiCredit                      $1,500.00

报表查看器中的内容。用户将能够选择特定日期。用于从中提取信息的Access数据库表如下所示。

  RECEIPT
-----------
ReceiptNumber (PK)
ReceiptDate
TotalPrice
TransactionType
MultiCash
MultiCheck
MultiCredit
TotalTax

可能还有其他任何方法吗？

感谢所有帮助。

类似的条款：

IIf(MultiCash = 0, 0, MultiCash)

绝对没有。您说＆＃34;如果multicash为0，则使用0，否则使用值...＆＃34;

这看起来像是一种过于复杂的方式。试试这个，它会以稍微不同的格式为您提供数据，但我怀疑它会接近您之后的数据

SELECT TransactionType, 
       SUM(TotalPrice)  AS SumTotalPrice,
       SUM(MultiCash )  AS MultipleCash,
       SUM(MultiCredit) AS MultipleCredit,
       SUM(MultiCheck ) AS MultipleCheck
FROM  Receipt 
WHERE ReceiptDate BETWEEN ? AND ?
GROUP BY TransactionType

它还有一个好处，即查询将自然处理以后引入的新支付类型。

在SQL语句中无法识别'='
