您好，我在下面有以下代码......

对于某个报告，因为我在程序运行期间无法添加进度条（它会导致应用程序无响应）我添加了一个名为＆＃34; ins＆＃34;只是为了查询每个查询的整个过程，然后在它之间添加一个ui操作，请参阅下面的代码：

Public Sub processRevRank(ByVal MyDate1 As String, ByVal MyDate2 As String)

    '-- LATEST CODE AS OF JUNE 08, 2017
    Dim RSC As ADODB.Recordset
    Dim sDate As String
    sDate = Format(MyDate1, "yyyy-mm-dd")

    Dim xDays As Integer
    If MyDate1 = "" And MyDate2 <> "" Then
        MyDate2 = MyDate1
        xDays = DateDiff("d", MyDate2, MyDate2)
    ElseIf MyDate1 <> "" And MyDate2 = "" Then
        MyDate1 = MyDate2
        xDays = DateDiff("d", MyDate1, MyDate1)
    ElseIf MyDate1 <> "" And MyDate2 <> "" Then
        xDays = DateDiff("d", MyDate1, MyDate2)
    Else
        Unload frmLoadingReports
        Exit Sub
    End If

    Dim xWidth As Integer
    If xDays <> 0 Then
        xWidth = 886 / xDays
    Else
        xWidth = 886
    End If

    Do Until CDate(sDate) > CDate(MyDate2)
        frmLoadingReports.lblTitle.Caption = "PROCESSING ( Rank by Company : " & sDate & " )"

        frmLoadingReports.lblLoadingTitleBack.Caption = "Deleting Records"
        frmLoadingReports.lblLoadingTitleFront.Caption = "Deleting Records"
        frmLoadingReports.picLoading.Width = frmLoadingReports.picLoading.Width + xWidth
        DoEvents

        Set RSC = Nothing
        Set RSC = OpenRS("CALL SP_Rank_by_Company('" & sDate & "','DELETE')")

        frmLoadingReports.lblLoadingTitleBack.Caption = "Inserting Records"
        frmLoadingReports.lblLoadingTitleFront.Caption = "Inserting Records"
        frmLoadingReports.picLoading.Width = frmLoadingReports.picLoading.Width + xWidth
        DoEvents

        Set RSC = Nothing
        Set RSC = OpenRS("CALL SP_Rank_by_Company('" & sDate & "','INSERT')")

        frmLoadingReports.lblLoadingTitleBack.Caption = "Updating Records"
        frmLoadingReports.lblLoadingTitleFront.Caption = "Updating Records"
        frmLoadingReports.picLoading.Width = frmLoadingReports.picLoading.Width + xWidth
        DoEvents

        Set RSC = Nothing
        Set RSC = OpenRS("CALL SP_Rank_by_Company('" & sDate & "','UPDATE_NNN1')")

        frmLoadingReports.lblLoadingTitleBack.Caption = "Updating Room Tariff Description"
        frmLoadingReports.lblLoadingTitleFront.Caption = "Updating Room Tariff Description"
        frmLoadingReports.picLoading.Width = frmLoadingReports.picLoading.Width + xWidth
        DoEvents

        Set RSC = Nothing
        Set RSC = OpenRS("CALL SP_Rank_by_Company('" & sDate & "','UPDATE_ROOMTARIFFDESC')")

        frmLoadingReports.lblLoadingTitleBack.Caption = "Updating Room Description"
        frmLoadingReports.lblLoadingTitleFront.Caption = "Updating Room Description"
        frmLoadingReports.picLoading.Width = frmLoadingReports.picLoading.Width + xWidth
        DoEvents

        Set RSC = Nothing
        Set RSC = OpenRS("CALL SP_Rank_by_Company('" & sDate & "','UPDATE_ROOMDESC')")

        frmLoadingReports.lblLoadingTitleBack.Caption = "Updating Marketcode"
        frmLoadingReports.lblLoadingTitleFront.Caption = "Updating Marketcode"
        frmLoadingReports.picLoading.Width = frmLoadingReports.picLoading.Width + xWidth
        DoEvents

        Set RSC = Nothing
        Set RSC = OpenRS("CALL SP_Rank_by_Company('" & sDate & "','UPDATE_MARKETCODE')")

        sDate = DateAdd("d", 1, MyDate1)
        sDate = Format(sDate, "yyyy-mm-dd")
    Loop

    frmLoadingReports.lblLoadingTitleBack.Caption = "Done"
    frmLoadingReports.lblLoadingTitleFront.Caption = "Done"
    frmLoadingReports.picLoading.Width = 5320
    DoEvents

    'timer for closing
    frmLoadingReports.Timer4.Enabled = True

    Exit Sub
End Sub

我仍然不满意，因为没有响应仍然发生，我正在考虑在查询中删除UPDATE部分，因为ui在事务和日期中挂起了该部分。

我的问题是...... 如何在其上创建带有SELECT table1的存储过程，然后使用所选记录UPDATE table2并将其循环直到满足某个条件？任何循环选择和更新的简单sql存储过程？

谢谢！

不是试图在UI中修复此问题（或作为第一步），您是否满意自己已经调整数据库以尽可能高效地运行这些查询？

mysql和vb6-stored过程
