好的，这就是把我的头发拉出来的原因！我有一个页面，它从一个 DB 中的表中读取记录，稍微操作数据，然后将其写入另一个 DB。

在 Do While Not EOF 循环中，我有许多 If Then Else 语句来操作数据。

如果我完整地运行代码，大多数 If Then Else 都不起作用，如果我只运行其中每个页面，它们就可以正常工作。

我已经花了 8 小时以上的时间来解决这个问题，但仍然感到困惑

我和影子巫师在一起。整理你的代码，每个键只使用一次 rsndb。并使用字典以合理的名称存储您的字段。就像现在一样，它是不可维护的：有人怎么知道 fieldStr12 代表什么？

我发现了一个真正的错误：您对原始字符串进行了三次替换，因此实际上只有最后一次替换可见。

建议如何整理您的代码：

Do While not rsndb.EOF

    Set fld = createObject("Scripting.Dictionary")
    fld.Add "webdate",      rsndb("webdate")
    fld.Add "propvendor",   rsndb("propvendor")
    fld.Add "propcountry",  rsndb("propcountry")

    ' etc...

    Select Case fld("proploc")
        Case "FLOR"     fld("propcountry") = fld("proploc")
        Case "MADE"     fld("propcountry") = fld("proploc")
    End case

    If fld("propcountry") = "ESC" Then 
        fld("propcountry") = fld("propcountry") & left(fld("proploc"),1)
    End If

    ' This part is not correct, it is only replacing the ' by an empty string
     'resnamestr = replace(rsndb("resname"),chr(13)," ")
     'resnamestr = replace(rsndb("resname"),chr(34),"")
     'resnamestr = replace(rsndb("resname"),"'","")
     'fieldstr4 = resnamestr

    fld("resname") = replace(fld("resname"), chr(13), " ")
    fld("resname") = replace(fld("resname"), chr(34), "")
    fld("resname") = replace(fld("resname"), "'", "")

    ' etc...

    Set Connection1 = Server.CreateObject("ADODB.Connection")
    Connection1.Open "DSN=website"
    cSql = "INSERT INTO newtandltest(datefield, field1, field2, field3, field4, field5, field6, field7, field8, field9, field10, field11, field12, price, bargainprice)"

    ' the Items property of a dictionary is an array in the same order that you add them to the dictionary
    ' You could do the same with the Keys property.
    cSql = cSql & "VALUES('" & join(fld.Items, "','") & "');"
    Connection1.Execute (cSql)
    Connection1.Close
    Set Connection1 = Nothing
    rsndb.MoveNext
Loop

Something u can improve in your code.

1) You have open connection before while loop so you do not need to open it again in While loop it should be remove 

Set Connection1 = Server.CreateObject("ADODB.Connection")
    Connection1.Open "DSN=website
While loop ...
WEND
Connection1.Close
    Set Connection1 = Nothing

2) check Null and blank before replacing with some value.

for e.g 
if(fld("resname") <> "" AND NOT ISNULL(fld("resname")))
replace(fld("resname"), chr(13), " ")
end if

- Note track loop with default value like response.write ("hello") and check in which row loop is breaking and by which cause

我能看到的唯一可能导致这种情况的是多次阅读同一个字段；对于某些类型的字段（例如 Access 的备注字段），它可能会在第一次阅读后变为空白。

要解决此类问题，您需要读取每个字段一次，并将其存储到局部变量中：

Do While not rsndb.EOF
    curPropLoc = rsndb("proploc")
    curPropCountry = rsndb("propcountry")
    '...
    fieldstr3 = curPropCountry
    If curPropLoc = "FLOR" Then
        fieldstr3 = curPropLoc
    End If
    If curPropLoc = "MADE" Then
        fieldstr3 = curPropLoc
    End If
    '...keep using curPropLoc instead of rsndb("proploc") throughout the loop...
    '...keep using curPropCountry instead of rsndb("propcountry") throughout the loop...
    '......
    rsndb.MoveNext
Loop
