我正在自学 CF 开发，并在学习时使用共享的 CF 托管站点进行测试。

我有一个包含 2500 多条数据记录的电子表格，大约 15 列。电子表格包含对该应用程序的基础至关重要的数据。它是离线维护的，并定期使用cffile. 上传后，电子表格将逐行导入 MySQL 表中。

问题是它花费的时间太长了。例如，它当前正在运行。在过去的 43 分钟内，只有 2500 条记录中的 192 条被添加到 MySQL 表中。有没有更有效的方法来做到这一点？

如果您查看下面的代码，它会在cfloop其中运行 cfspreadsheet 标记，并检索当前行。然后将该行作为“CSV”数据添加到 MySQL 表中。

关于如何更有效地做到这一点的任何建议？ 

<cfloop index="RecordNumber" from="2" to="#Records#" step="1"> 

    <cfspreadsheet action="read"
                format="csv"
                name="siteinfo"
                src="#floc#"
                headerrow="1"
                rows="#RecordNumber#" 
                columns="1-7,15,16,22,23"
                >

    <cfset ColumnCount = ListLen(siteinfo)>
    <cfset CSVSiteData = #siteinfo#>
    <cfset EntryType = "Site_Data">


    <cfquery name="Insertsite" datasource="TechData">
        INSERT INTO sitelist (EntryType, CSVSiteData, DateInserted)
        VALUES ('#EntryType#', '#CSVSiteDataf#', '#DateInserted#')
    </cfquery>

</cfloop>

您每次迭代都读取整个 XLS 文件，只是为了获取一行。只需读取一次文件（在循环之前），然后遍历其行。

是的，试图找到一种方法来避免每次通过都打开电子表格，这修复了它......现在快得多......

<body bgcolor="#0033FF">
    <cfset filenm = "SitesTest.xlsx">
    <cfset thisPath = GetDirectoryFromPath(ExpandPath("*.*"))>
    <cfset uploaddirectory = "#thisPath#Uploads\">
    <cfset uploadfile = "#uploaddirectory##filenm#">
    <cfset floc = "#uploadfile#">
