Question

请考虑以下结构数组的快照：

我的数据库架构如下：

我想计算结构键值的总和，并将总数存储到数据库中。例如，我想在阻塞列下存储146 + 1 = 147值，类似地，在弹跳列等中存储4 + 1 + 2 = 7。

到目前为止，我一直在以下列方式访问非常简单的密钥（如插入语句中所示）：

 <cfquery datasource="XX.XX.X.XX" name="qCoulmnInsert">
INSERT INTO 
             mytable (blocked_int,
                      bounce_int,
                      date_dt,
                      deferred_int,
                      delivered_int,
                       drop_int                                                                                                                      

                                                                        )

  VALUES
              <!--- loop through your array --->
             <cfloop from="1" to="#arrayLen(cfData)#" index="i">
             ( <!--- 1 --->
              <cfif structKeyExists(cfData[i], "blocked")>
                <cfqueryparam CFSQLTYPE="CF_SQL_INTEGER" value="#cfData[i]["blocked"]["Other"]#">
              <cfelse>
                 NULL

              </cfif> ,
              <!--- 2 --->
              <cfif structKeyExists(cfData[i], "bounce")>
                <cfqueryparam CFSQLTYPE="CF_SQL_INTEGER" value="#cfData[i]["bounce"]["At & T"]#">
              <cfelse>
                 NULL
              </cfif> ,

我想知道，有没有办法总结按键的值，因为从图像中可以看出，按键不是固定的，因为阻止，反弹，延迟等等。

请告知。

错误：

运行下面提到的方法后，我得到以下错误：

The value Cox cannot be converted to a number.

The error occurred in C:myfile.cfm: line 38

36 :             <cfset total = 0>
37 :             <cfloop item="subkey" collection="#struct[key]#">
38 :                 <cfset total += subkey>
39 :             </cfloop>
40 :             <cfset totals[key] = total>

不确定Cox在这里是什么？

另外，如果我在INSERT语句的上下文中讨论，我将如何在<cfqueryparam>标签周围进行调整，我必须在其中定义总值？

请告知。

进一步问题：

好的，基于下面提到的例子我有以下输出：

enter image description here

我想在数据库的单个列中插入日期和值的值。我想在所有日期重复相同的事情。

所以这就是我试图做的事情：

<cfquery datasource="10.11.0.130" name="qCoulmnInsert">
INSERT INTO 
   simplexresults.contactresults_email_account_summary_isps     (date_dt,
                                                                                                     blocked_int,
                                                                 bounce_int,
                                                                 deferred_int,
                                                                 delivered_int,
                                                                 drop_int,
                                                                 open_int,
                                                                 processed_int,
                                                                 request_int,
                                                                 spamreport_int,  
                                                                 uniqueopen_int
                                                                                                                                                              )

  VALUES

              <cfelse>
                 NULL
              </cfif> ,

以上的事情不起作用。此外，由于日期现在可变，我该如何处理呢？

这是我的sqlfiddle：

请告知。

我在“VALUES”子句之后使用了以下代码并收到一个错误：

我在这里做错了吗？我假设coldfusion没有链接访问转换日期数组作为cfif检查中的Structkeyexists，但即使单独测试它，如下所示产生相同的错误：

<cfloop from = "1" to="#arrayLen(dateArray)#" index="i">

<cfoutput>#dateArray[i].blocked#</cfoutput>

</cfloop>

Answer 1

首先循环结构。其次检查该struct元素的内容本身是否为struct（因此我们可以删除'date'键）。然后循环遍历该结构，总计其键的值。也许有点像这样的东西。我使用了一个单独的结构来保存总数。然后我只循环该结构来更新数据库。

<cfset totals = {}>

<cfloop index="struct" array="#cfData#">
    <cfset totals[struct.date] = {}>
    <cfloop item="key" collection="#struct#">
        <cfif isStruct(struct[key])>
            <cfset total = 0>
            <cfloop item="subkey" collection="#struct[key]#">
                <cfset total += struct[key][subkey]>
            </cfloop>
            <cfset totals[struct.date][key] = total>
        </cfif>
    </cfloop>
</cfloop>

添加键的值
