查询表达式“PopID =”中的 VBA 语法错误（缺少运算符）

Question

以下代码在尝试运行时会引发错误，我想我已经设法实际连接到数据库并且我选择了一个单元格，所以不确定缺少什么。

错误：

查询表达式“PopID =”中有语法错误（缺少运算符）。

理想情况下，我希望能够在每次运行宏时列出四个单元格，这些单元格将进入四列访问附加

Const TARGET_DB = "testdb.accdb"

Sub AlterOneRecord() 'not working yet

   Dim cnn As ADODB.Connection
   Dim rst As ADODB.Recordset
   Dim fld As ADODB.Field
   Dim MyConn
   Dim lngRow As Long
   Dim lngID As String
   Dim j As Long
   Dim sSQL As String

                   'determine the ID of the current record and define the SQL statement
                   lngRow = ActiveCell.Row
                   lngID = Cells(lngRow, 1).Value

   sSQL = "SELECT * FROM tblPopulation WHERE PopID = " & lngID

   Set cnn = New ADODB.Connection
   MyConn = ThisWorkbook.path & Application.PathSeparator & TARGET_DB

   With cnn
     .ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;"
     .Open MyConn
   End With

   Set rst = New ADODB.Recordset
   rst.CursorLocation = adUseServer
   rst.Open Source:=sSQL, _
            ActiveConnection:=cnn, _
            CursorType:=adOpenKeyset, _
            LockType:=adLockOptimistic

   'Load contents of modified record from Excel to Access.
   'do not load the ID again.
   For j = 2 To 7
      rst(Cells(1, j).Value) = Cells(lngRow, j).Value
   Next j
   rst.Update

   ' Close the connection
   rst.Close
   cnn.Close
   Set rst = Nothing
   Set cnn = Nothing
End Sub

我觉得奇怪的是它们都是 M$ 产品，没有很好的文档记录或者真的很容易执行。也许我会以错误的方式去做。

例如，我怎样才能让它包含单元格 A1 和 B2？

Answer 1

你需要引用字符串

sSQL = "SELECT * FROM tblPopulation WHERE PopID = '" & lngID & "'"
