访问变量未定义错误

Question

我在Access窗体中有以下VB代码。我已将字段Market添加到我的查询中，字符串太长。所以我不得不把它分成两个陈述。它似乎工作。我的问题是与行：

Market = rs("Market") 

我得到变量未定义的错误。这是在我的查询。它已被添加到生成该表单的查询中......我不知道从哪里开始寻找......任何帮助都非常感谢。

Answer 1

当访问抱怨在这一行“没有定义变量” ......

Market = rs("Market") 

...问题是Market在行首; Access认为这是未声明的变量的名称。如果rs("Market")是问题，则错误消息将是关于在收集中找不到的项目。

如果您的表单不包含名为的市场，您可能会遇到问题。无论是在解释，并Me!前缀控制的名称，以便访问明白你的意思是在窗体的默认集合命名项目（这是它Controls集）......

Me!Market.Value = rs("Market")

试试这个：

Dim db As DAO.Database, rs As DAO.Recordset 
Dim strSQL As String 

Set db = CurrentDb() 

strSQL = "SELECT TOP 1 CPOrders.Cust, Customer.NAME, CPOrders.CP_Ref, CPOrders.Slsman, CPOrders.Assistant, CPOrders.Date_opn, " & _ 
strSQL = strSQL & "CPOrders.CPSmall, CPOrders.InvIssu, CPOrders.InvNo, CPOrders.InvDate, CPOrders.DueDate, " & _ 
strSQL = strSQL & "CPOrders.ETADate, CPOrders.Closed, CPOrders.Cust, CPOrders.Name, CPOrders.BuyerRef, CPOrders.ToCity, " & _ 
strSQL = strSQL & "CPOrders.ToState, CPOrders.ToCtry, CPOrders.ToPort, CPOrders.Supplier, CPOrders.Origin, CPOrders.Product, " & _ 
strSQL = strSQL & "CPOrders.GradeType, CPOrders.NoUnits, CPOrders.Pkg, CPOrders.Qty, CPOrders.TotSale, CPOrders.TotCost, " & _

strSQL = strSQL & "CPOrders.Ord_Terms, CPOrders.Invoice_ID, CPOrders.Movement_Type, CPOrders.Market " & _ 
strSQL = strSQL & "FROM Customer INNER JOIN CPOrders ON Customer.[CUST_#] = CPOrders.Cust ORDER BY CPOrders.Invoice_ID desc;" 

Set rs = db.OpenRecordset(strSQL, dbOpenDynaset, dbReadOnly) 
rs.MoveFirst
