CFQUERY和CFIF比較的意外結果

這段代碼正在生產中，以根據使用情況阻止IP。觸發了一封電子郵件，並執行了一個插入，其IP地址滿足cfif條件。但是，當我在SQL編輯器中執行查詢時，對於相同的IP，它將計數返回爲0（即getNineHundredCnt.maxDownload）。CFQUERY和CFIF比較的意外結果

這發生只有一個用戶。對於其他用戶來說，它工作得很好，幾乎有1L用戶每天都可以訪問應用程序。任何人都可以幫助解釋爲什麼發生？

<cfquery name="getExcessiveUsageConfig" DATASOURCE="#arguments.datasrc#"> 
    SELECT * FROM ExcessiveUsageConfig 
</cfquery> 

<cfset usageLimitStruct.maxFifMinDownload = getExcessiveUsageConfig.MAXFIFMINDOWNLOAD > 

<!---- This value is 900 and not changed ---> 
<cfquery name="getNineHundredCnt" DATASOURCE="#arguments.datasrc#"> 
    SELECT 
     (select count(9) 
      from downloads 
      where download_time > dateadd(minute,-15,getdate()) 
      and USER_IP = <cfqueryparam value="#remoteAddress#" cfsqltype="CF_SQL_VARCHAR"> 
     ) as maxDownload, 
     (select TOP 1 DATEDIFF(second, DOWNLOAD_TIME, GETDATE()) 
      from CAPTCHA 
      WHERE USER_IP = <cfqueryparam value="#remoteAddress#" cfsqltype="CF_SQL_VARCHAR"> 
      and Erights_sessionId = <cfqueryparam value="#arguments.erightsCookie#" cfsqltype="CF_SQL_VARCHAR"> 
      order by DOWNLOAD_TIME DESC 
     ) as Ccheck 
</cfquery> 


<cfif getNineHundredCnt.maxDownload gte usageLimitStruct.maxFifMinDownload> 

    <cfquery name="checkToBlockIpExcessUsage" DATASOURCE="#arguments.dataAuthentication#"> 
     INSERT INTO DisabledIPs(IP,TIMEDISABLED) 
     VALUES (<cfqueryparam value="#remoteAddress#" cfsqltype="CF_SQL_VARCHAR">,GETDATE()) 
    </cfquery> 

    <cfmail from="[email protected]" to="[email protected]" subject="IP Blocked" type="text">

    The IP has been blacklisted 
    </cfmail> 

</cfif>

如果查詢超時，是否有機會返回0作爲sql查詢的值？ –

ExcessiveUsageConfig中有多少行？ –

它的唯一一行，並且列MAXFIFMINDOWNLOAD的值是900 –
