小编Lei*_*igh的帖子

尝试在Graph API Explorer中运行它:

"query1":"SELECT uid, message FROM status where uid in (SELECT uid2 from friend where uid1 = me())"

"query2":"SELECT name from user where uid in (select uid from #query1)"

但我得到的只是:

{ "data": [ ]  }

我完全是新手.我究竟做错了什么？

是否可以从给定的URL下载pdf并使用ColdFusion将其保存到服务器？我正在寻找一个类似于file_put_contents()PHP 的方法 ,我在Adobe文档中找不到任何东西.谢谢!

我想恢复从当前时间开始超过5分钟的记录.这是我到目前为止所做的,但它似乎带回了所有记录,而不仅仅是超过5分钟的记录:

SELECT COUNT(DISTINCT "DOCUMENT_QUEUE"."DOCUMENT_NUMBER") as "Records" 
FROM   "MAGINUS"."DOCUMENT_QUEUE" "DOCUMENT_QUEUE"
WHERE  to_date('01-JAN-1970', 'dd-MON-yyyy HH:MI:SS') + (DOCUMENT_QUEUE.CREATION_DATE/86400) > sysdate - 38/1440
ORDER BY "DOCUMENT_QUEUE"."DOCUMENT_NUMBER"

我正在使用ColdFusion开发Flash Builder\Flex Mobile应用程序.我需要帮助来修复我的搜索功能.当我尝试搜索某些内容时,我必须输入确切的单词,否则它不返回任何内容.

如果我只键入"app",而不是"applet",它什么也不返回.

搜索功能:

<cffunction name="getwordsSummaryByTerm" output="false" access="remote"  returntype="Query" > 
    <cfargument name="searchStr" type="string"  required="true" /> 
    <cfset var qItem=""> 
    <cfquery name="qItem" datasource="databaseyo">
        SELECT * 
       FROM words 
       WHERE term = <CFQUERYPARAM CFSQLTYPE="CF_SQL_VARCHAR" VALUE="#ARGUMENTS.searchStr#"> 
    </cfquery> 
     <cfreturn qItem> 
</cffunction> 

Flex代码:

protected function doSearch(event:MouseEvent):void
{
    if(searchTerm.text!="")
    { 
        getAllwordsResult.token = wordsService.getwordsSummaryByTerm(searchTerm.text); 
    } 
    else
    { 
        getAllwordsResult.token = wordsService.getAllwords(); 
    } 
}

这段代码:

string currentPrice = String.Format("{0:c}", ((TblProduct)e.ListItem).Price);

以美元显示价格,即$320.00.但我想显示一个比索符号而不是一个美元符号.我应该使用什么system.string？{?:?}

我想从列表中循环选定的数字(cfselect).我尝试了getElementById但只能在同一页面上显示它.我无法将此数字传递给循环.有人能帮我吗？谢谢.

function item()

        var a = document.formName.numList.selectedIndex;
        document.getElementById('i').value = document. family.tBro.options[a].value;

        var n=document. family.tBro.options[a].value;

        <option value="2"> 2</option> 
        <option value="3"> 3</option>  
        <option value="4">4</option>
    </cfselect>

我有一个分页的表单页面.我想保留表单值,因为用户使用分页进入上一页或下一页.我知道可以使用会话范围来完成.但是,这里我不想使用会话范围.有没有人对如何在不使用会话时这样做有任何想法？请告诉我.

这是我的表单页面:

<cfoutput>          
    <form action="#buildUrl(action='survey.save_surveyresults',querystring='surveyId=#rc.surveyid#')#"  method="post">
        <input type="hidden" name="id" value="0">
        <input type="hidden" name="surveyid" value="#rc.surveyId#">

我编写了bellow函数来查找字符串中最常出现的char,它适用于:

1. "你好,世界!"
2. "你好吗？"
3. "One"(如果字符串只有唯一字母,则返回第一个字母字符)

它在以下字符串"Lorem ipsum dolor sit amet"中失败.最常见的字母都有3次出现,它会产生一个空白字符串而不是给我一个(它应该按字母顺序给出第一个)

def frequent_char(text):

    charset = ''.join(sorted(text))

    maxcount = 0
    maxchar = None

    for item in charset.lower():
        charcount = text.count(item)

        if charcount > maxcount :
            maxcount = charcount
            maxchar = item

    return maxchar

我没有在代码中犯的错误.有人可以帮忙吗？

我正在使用以下内容进行数据转换:

<cfset Year = Left(mbTimeStamp_dt,4)>
<cfset Month = mid(mbTimeStamp_dt,5,2)>
<cfset Date = mid(mbTimeStamp_dt,7,2)>
<cfset Hour = mid(mbTimeStamp_dt,9,2)>
<cfset Minute = right(mbTimeStamp_dt,2)>
<cfset NewDate= "#Createdatetime(Year,Month,Date,Hour,Minute,00)#">

<cfset PSTTime = #DateConvert("UTC2Local", NewDate )# >
<cfset ESTTime = DateAdd('h',3,PSTTime)>   

但我在以下行收到错误:

<cfset NewDate= "#Createdatetime(Year,Month,Date,Hour,Minute,00)#">

错误消息:"值1-无法转换为数字."

难道我做错了什么？供您参考,我的mbTimestamp_dt价值如下:

这可能是一个愚蠢的问题,但我真的希望有人可以帮助我.

我目前正在serializeJson()ColdFusion 10中使用生成JSON数据集,以便我可以在jquery表插件中处理数据.serializeJson()生成以下JSON数据:

{
-COLUMNS: [
"AMOUNT"
"AMOUNTPAID"
"ENTITY"
"ENTITY_NAME"
"FORMULACURRENCY"
"INTERNALID"
"TRANDATE"
"TRANID"
"TYPE"
"TYPE_INTERNALID"
]
-DATA: [
...

我的插件似乎只处理非常基本的JSON.

如何仅从ColdFusion的serializeJson()函数获取数据的数组,而不是列表或任何其他元数据？或者,是否有一种简单的方法只从数据数组中获取内容,而没有其他数组？
