为什么这个DAO记录集查询没有返回任何结果？

Question

我正在使用Access 2007数据库并且我已经设置了DAO记录集查询，但是它没有返回任何结果。它没有抛出任何错误，只是没有结果。 Me.ProID是一个文本字段，它包含字母和数字。我认为它与文本字段有关，可能是引用的位置。

Dim contractSQL As String
Dim contractDB As DAO.Database
Dim contractRS As DAO.Recordset

contractSQL = "SELECT Top 1 ContractName, ItemDescription, Price FROM ContractPricing WHERE AccountNo = " & Me.Parent.[AccntNumber] & " AND PartNo = " & """ & Me.ProdID & """ & " ORDER BY Price Asc"

Set contractDB = CurrentDb
Set contractRS = contractDB.OpenRecordset(contractSQL)

Debug.Print contractRS.RecordCount

Answer 1

字符串连接可能是错误的。 " & """ & Me.ProdID & """ & "几乎肯定是'" & Me.ProdID & "'

Answer 2

我不知道你是指这个：

contractSQL = "SELECT Top 1 ContractName, ItemDescription, Price FROM ContractPricing WHERE AccountNo = " & Me.Parent.[AccntNumber] & " AND PartNo = " & Me.ProdID & " ORDER BY Price Asc"

我不确定这是否会对你有所帮助。我也是新手。但希望它会。
