CFML将evaluate()查询字符串转换为结构语法

Question

下面我有一个循环内的代码,以便将循环迭代我的动态变量设置temp到的值getAdvisor_Advisors.advisor_ID用于当前循环迭代.

<cfset temp = "getAdvisor_Advisors#LoopCount#.advisor_ID">

下面的cfinvoke调用我在动态"temp"变量中传递的查询,但必须使用它周围的慢评估(temp)来获取正确的值.

<cfinvoke component="com.appointments" method="get_All_Appointments" returnvariable="getAppointments">
      <cfinvokeargument name="Advisor_ID" value="#evaluate(temp)#">
      <cfinvokeargument name="StartDay" value="#dateFormat(form.cal,'dd')#">
      <cfinvokeargument name="StartMonth" value="#dateFormat(form.cal,'mm')#">
      <cfinvokeargument name="StartYear" value="#dateformat(form.cal,'yyyy')#">             
</cfinvoke>

我想重写temp变量evaluate()而不使用evaluate.我被告知我可以使用结构语法来引用它,如下所示:

没有评估:

<cfset foo = qBar["text#lang#"][CurrentRow]>
getAdvisor_Advisor["advisor_ID"][CurrentRow]

我该怎么改写

<cfset temp = "getAdvisor_Advisors#LoopCount#.advisor_ID">

使用结构语法？

添加更多代码,以便您可以看到为什么这很复杂,这些是复合循环.

Answer 1

要回答这个问题，您可以使用 QueryToStruct。设置一个数组，每个索引都是查询的结构。

<!--- CREATE THE ARRAY --->
<cfset temp = arrayNew(1)>

<cfquery name="getAdvisor_Advisors1" dbtype="query" cachedWithin="#CreateTimeSpan(0,0,15,0)#">
    Select *
    rom getAdvisors
    Where Express = 'FR/SO' 
    Order by Specialization, Advisor
</cfquery>

<!--- CREATE AND FILL THE STRUCT --->
<cfset temp[1] = QueryToStruct(getAdvisor_Advisors1)>

然后您可以循环该数组temp并输出值。

<cfloop from="1" to="#arrayLen(temp)#" index="t">
    ...
    <cfinvokeargument name="Advisor_ID" value="#temp[t].advisor_ID#">
    ...
</cfloop>

这是它工作的屏幕截图：

原始答案：cfloop为什么不使用, 或 的 查询cfoutput？然后就很简单了：

<cfloop query = "getAdvisor_Advisor">
<cfinvoke component="com.appointments" method="get_All_Appointments" returnvariable="getAppointments">
      <cfinvokeargument name="Advisor_ID" value="#getAdvisor_Advisors.advisor_ID#">
      <cfinvokeargument name="StartDay" value="#dateFormat(form.cal,'dd')#">
      <cfinvokeargument name="StartMonth" value="#dateFormat(form.cal,'mm')#">
      <cfinvokeargument name="StartYear" value="#dateformat(form.cal,'yyyy')#">             
</cfinvoke>
</cfloop>
