Question

我需要就如何从vb6代码调用存储过程来检索一组状态消息以告知用户报告过程报告所处的位置提供一些指导。

商店程序的输出是：

JobOrder    BatchJobTypeID  Status                                  
1           3               Previous Quarter Closed Successfully    
2           1               Reporting Quarter Opened on: Feb 14 2017

我知道我可以使用For循环遍历记录集，我不确定的是，如何在一行中连接包含Status的两个单独的行。

看到Zohar Peled（thx）发布的第一个答案。我继续编写子例程来完成这项任务。通过简单一瞥它，它看起来是否正确？

Private Sub Form_Load()

    Dim cmd As New ADODB.Command
    Dim con As ADODB.Connection
    Dim rs As ADODB.Recordset

    Dim strStatus As String
    strStatus = ""

    On Error GoTo errhandler

    Set con = New ADODB.Connection
    With con
        .ConnectionString = GetConnectionString("Reporting")
        .Open
    End With

    Set cmd = New ADODB.Command
    With cmd
        .ActiveConnection = con
        .CommandType = adCmdStoredProc
        .CommandText = "[dbo].[DisplayJobStatus]"
    End With

    Set rs = cmd.Execute

    While Not rs.EOF
        strStatus = strStatus & rs("Status")
        rs.MoveNext
    Wend

    rs.Close
    Set rs = Nothing
    con.Close
    Set con = Nothing

End Sub

非常感谢。

如果我没记错的话，就像这样：

Dim AllStatuses As String
AllStatuses = ""
' Declare, create and open the connection and recordset code here

While Not Rs.EOF
    AllStatuses = AllStatuses & Rs("Status")
    Rs.MoveNext
Loop
' Close recordset and connection here
