经典ASP将变量值到Access数据库

问题描述：

我试图插入一个变量值到我的Access数据库，我可以插入一个值，是预先设定的像经典ASP将变量值到Access数据库

<td width="125" nowrap="nowrap" ><div align="right">Lead From </div></td> 
    <td><input name="lead" type="text" id="lead" value="" size="50" /></td>

，你可以看到我们有一个的ID“领导”，我可以插入到数据库罚款是这样的：

MM_fieldsStr = "lead|value"; 
MM_columnsStr = "Lead|',none,''"; 

' create the MM_fields and MM_columns arrays 
MM_fields = Split(MM_fieldsStr, "|") 
MM_columns = Split(MM_columnsStr, "|") 


' set the form values 
For MM_i = LBound(MM_fields) To UBound(MM_fields) Step 2 
    MM_fields(MM_i+1) = CStr(Request.Form(MM_fields(MM_i))) 
Next

现在我希望能够做这样的事情：

Session("MM_JobNumber") = job_number 
MM_fieldsStr = job_number & "|value" 
MM_columnsStr = "Job_Num|',none,''"

当我尝试通过它传递一个变量返回null，OFC你不能看到在我提供的代码中设置的工作号码，但它确实100％得到设置。

COUNTER RECORDER ::

Dim countrec 
Dim countrec_numRows 

Set countrec = Server.CreateObject("ADODB.Recordset") 
countrec.ActiveConnection = MM_JobConn_STRING 
countrec.Source = "SELECT * FROM CounterTAB WHERE Counter_ID = 1" 
countrec.CursorType = 0 
countrec.CursorLocation = 2 
countrec.LockType = 1 
countrec.Open() 

countrec_numRows = 0

FULL下面的代码::

If (CStr(Request("MM_insert")) = "form2") Then 

    Dim job_number 


IF (Session("MM_JobNumber") <> "") OR (Session("MM_JobNumber") <> NULL)Then 
    job_number = Session("MM_JobNumber") 
Else 



    Dim new_count_num 
    new_count_num = countrec.Fields.Item("Counter_NUM").Value+1 
    job_number = PadDigits(new_count_num, 4) + "-" + mid(DatePart("yyyy",now()),3,2) 
    Session("MM_JobNumber") = job_number 



END IF 

    'UPDATE COUNTER 
    set counterupdate = Server.CreateObject("ADODB.Command") 
    counterupdate.ActiveConnection = MM_JobConn_STRING 
    counterupdate.CommandText = "UPDATE CounterTAB SET Counter_NUM = Counter_NUM + 1 WHERE Counter_ID = 1" 
    counterupdate.CommandType = 1 
    counterupdate.CommandTimeout = 0 
    counterupdate.Prepared = true 
    counterupdate.Execute() 

    MM_editConnection = MM_JobConn_STRING 
    MM_editTable = "Job_Details" 
    MM_editRedirectUrl = "view_jobs_new.asp?offset=-1" 
    MM_fieldsStr = job_number & "|value|hiddenDateRaised|value|hiddenYearRaised|value|hiddenNewRaisedBYID|value|hiddenRaisedBYID|value|hiddenFieldCompanyID|value|hiddenFieldContact1|value|Job_Ref_Name|value|checkbox3_1|value|checkbox3_15|value|checkbox3_4|value|checkbox3_2|value|checkbox3_16|value|checkbox3_5|value|checkbox3_3|value|checkbox3_6|value|checkbox3_7|value|checkbox3_22|value|checkbox3_8|value|checkbox3_9|value|checkbox3_23|value|checkbox3_10|value|checkbox3_20|value|checkbox3_11|value|checkbox3_17|value|checkbox3_12|value|checkbox3_21|value|checkbox3_13|value|checkbox3_18|value|checkbox3_24|value|checkbox3_14|value|checkbox3_19|value|checkbox3_25|value|checkbox3_26|value|DescriptText|value|sitename|value|siteAdd1|value|siteAdd2|value|siteAdd3|value|siteAdd4|value|siteAdd5|value|sitePostCode|value|lead|value"

斯普利特（）有隔板，分隔符不涉及。所以尾随的“|” in

MM_columnsStr = "Job_Num|',none,''|"

在数组中导致伪/空元素。证据：

>> s = "Lead|',none,''" 
>> a = Split(s, "|") 
>> WScript.Echo UBound(a), a(UBound(a)) 
>> 
1 ',none,'' 
>> s = "Job_Num|',none,''|" 
>> a = Split(s, "|") 
>> WScript.Echo UBound(a), a(UBound(a)) 
>> 
2

关于第二个想法：

这

>> job_number = "JN" 
>> MM_fieldsStr = job_number & "|value" 
>> WScript.Echo MM_fieldsStr 
>> 
JN|value

应该证明，该字符串连接工作在VBScript中。如果你

|value

然后job_number是&前行空。也许你的意思

job_number = Session("MM_JobNumber")

，而不是

Session("MM_JobNumber") = job_number

最后一个念头：

此：

IF (Session("MM_JobNumber") <> "") OR (Session("MM_JobNumber") <> NULL)Then 
    job_number = Session("MM_JobNumber")

将设置job_number仅是不空或空。

感谢您指出了这一点东西，我意外地增加了一个额外|进入后，但不是在代码中，试图做这个这么久的习惯的力量，我只是不知道如何传递一个变量。 – 2015-03-03 12:30:36

工作号码变量设置之前，实际上生病发布整个代码部分，让你看到什么即时通讯 – 2015-03-03 12:46:15

工作号码仍然会被设置在它下面的else语句中，我已经删除了if语句只是让它设置在石头上，我仍然得到：Microsoft Access数据库引擎错误'80004005' 字段'Job_Details.Job_Num'不能是一个零长度的字符串。 – 2015-03-03 13:05:35

一切都需要的是垫job_number串出与“”在开始和结束标记，希望这可以帮助其他人试图做类似
