Coldfusion根据txt中的值对行进行排序

Question

我有一个txt文件，并希望根据每行中的值来排序所有行。

实现这一目标的最佳和最快方法是什么？

以下是我用来编译txt文档的代码：

<!---CSV FILE--->
<cffile action="read" file="C:/ColdFusion10/cfusion/wwwroot/kelly2/debitorders.csv" variable="csvfile">

<cfoutput>
<!---LOOP THROUGH CSV FILE--->
<cfloop index="index" list="#csvfile#" delimiters="#chr(10)##chr(13)#">

        <!---SET VALUES--->
        <cfset accountholder = "#listgetAt('#index#',1)# #listgetAt('#index#',2)#">
        <cfset accountholderlname = "#listgetAt('#index#',2)#">
        <cfset accountnumber = "#listgetAt('#index#',3)#">
        <cfset accounttype = "#listgetAt('#index#',4)#">
        <cfset bankname = "#listgetAt('#index#',5)#">
        <cfset branch = "#listgetAt('#index#',6)#">
        <cfset amount = "#listgetAt('#index#',7)#">
        <cfset date = "#listgetAt('#index#',8)#">

       <!---SET INITIAL--->
       <cfset initial = "#left(accountholder,1)#">

       <!---SET LAST NAME--->
       <cfset lname_final = "#replace("#accountholderlname#"," ","","all")#">

       <!---GET AND SET ACC TYPE--->
       <cfif accounttype eq "cheque">
            <cfset accounttype_final = "CH">
       <cfelseif accounttype eq "savings">
            <cfset accounttype_final = "SAV">
       <cfelseif accounttype eq "credit">
            <cfset accounttype_final = "CR">
       <cfelse>
            <cfset accounttype_final = "OTH">
       </cfif>

       <!---SET AMOUNT--->
       <cfset amount_final = #round(amount * 100)#>
       <cfset amount_final = #NumberFormat(amount_final,"0000000")#>

       <!---SET DATE--->
       <cfset date_final = "#DateFormat(Date,"ddyyyymm")#">

       <!---TRIM VALUES--->
       <cfset initial = "#Left(initial, 1)#">
       <cfset lname_final = "#Left(lname_final, 14)#">
       <cfset accountnumber = "#Left(accountnumber, 13)#">
       <cfset accounttype_final = "#Left(accounttype_final, 3)#">
       <cfset branch = "#Left(branch, 9)#">
       <cfset amount_final = "#Left(amount_final, 7)#">
       <cfset date_final = "#Left(date_final, 8)#">

       <!---SET STRING LENGTH FOR EACH--->
       <cfset initial = "#LJustify(initial, 1)#">
       <cfset lname_final = "#LJustify(lname_final, 15)#">
       <cfset accountnumber = "#LJustify(accountnumber, 14)#">
       <cfset accounttype_final = "#LJustify(accounttype_final, 3)#">
       <cfset branch = "#LJustify(branch, 10)#">
       <cfset amount_final = "#LJustify(amount_final, 7)#">
       <cfset date_final = "#LJustify(date_final, 8)#">

       <!---SET TOTAL STRING--->
       <cfset total_string = "#initial##lname_final##accountnumber##accounttype_final##branch##amount_final##date_final#">

我不确定如果我开始使用数组执行此操作会更好，如果是这样，请提供建议。

我不确定是否可以检查，因为我插入每一行将其插入正确的位置，我以前从未听说过。

如果需要，我还可以在流程结束时循环访问txt文件。

使用cfhttp读取csv文件。 name属性创建一个查询对象。您可以使用Q的Q进行排序，然后继续。

详情请参阅cfhttp的文档。
