Question

我创建了一个模块，我正在使用存储过程从SQL DB读取数据，并且我获得了所有必需的数据，但我的要求是我还需要所有列名称/标题。我无法对名称进行硬编码，因为我正在将数据行转换为存储过程中的列。

这是我写的代码：

ConnStr = "PROVIDER=SQLOLEDB.1;"
ConnStr = ConnStr & "DATA SOURCE=" & dataSrc & "; INITIAL CATALOG=" & iCatalog & "; "
ConnStr = ConnStr & "User ID = " & dbUserId & "; Password = " & dbPassword

On Error GoTo ErrHandler

DBConn.Open ConnStr

' Create a recordset object.
Dim rsCounter As ADODB.Recordset
Set rsCounter = New ADODB.Recordset
Dim startDate As String, endDate As String, query As String

query = "Exec ReadCntrs 0, '12/01/2011', '12/30/2011'"

With rsCounter
    ' Assign the Connection object.
    .ActiveConnection = DBConn

    .Open query
    ' Copy the records into cell A1 on Sheet1.
    Sheet1.Range("A1").CopyFromRecordset rsCounter

    ' Tidy up
    .Close
End With

DBConn.Close
Set rsCounter = Nothing
Set DBConn = Nothing

ExitHere:
    On Error Resume Next
    DBConn.Close: Set DBConn = Nothing
    Err.Clear
    Exit Sub

ErrHandler:
    MsgBox Err.Number & Err.Description, vbExclamation
    Resume ExitHere

End Sub

Answer 1

With rsCounter
    ' Assign the Connection object.
    .ActiveConnection = DBConn

    .Open query

    ' Write the column names into cell A1 on Sheet1.
    Dim counter As Long
    For counter = 0 To rsCounter.Fields.Count - 1
      Sheet1.Range("A1").Offset(, counter).Value = rsCounter.Fields(counter).Name
    Next

    ' Copy the records into cell A2 on Sheet1.
    Sheet1.Range("A2").CopyFromRecordset rsCounter

    ' Tidy up
    .Close
End With

Answer 2

rsCounter.Fields(i).Name - 其中i是表示字段编号的整数 - 通常是您访问字段名称的方式。

编辑 - 也是为了获得您将使用的字段总数rsCounter.Fields.Count

如何在VBA中获取列名？
