因此時常我收到此錯誤，大多是由機器人引起：查詢不被列名的可轉位，但該列不應該存在
java.lang.IllegalArgumentException:
[Table (rows 0 columns ID, BOOKID, EDITIONID, EDITIONNAME, PRACTICEAREALINK, PUBLISHED):
...REALINK: [email protected]]
[PUBLISHED: [email protected]] ] is not indexable by webtypeid
但是要找到它指的是無處列在試圖引用的查詢中。
所以我們在這裏播放3個文件，一個index.cfm，一個Business.cfc和一個DAO.cfc。在業務代碼看起來像：
<cfcomponent extends="_lbr._core.NativeBusiness">
<cffunction name="init" access="public" output="false" returntype="_lbr._who._publication._Edition.EditionBusiness" hint="Pseudo-constructor">
<cfargument name="oEditionDAO" type="_lbr._who._publication._Edition.EditionDAO" required="true">
<cfscript>
super.init(argumentCollection=arguments);
variables.oEditionDAO = arguments.oEditionDAO;
return this;
</cfscript>
</cffunction>
<cffunction name="getEditionByPracticeArea" returntype="query" access="public">
<cfargument name="nEditionID" type="numeric" required="false">
<cfargument name="nPraciceAreaID" type="numeric" required="false">
<cfargument name="bPublished" type="boolean" required="false">
<cfscript>

</cfscript>
</cffunction>
<cffunction name="getEditionsByPracticeArea" returntype="query" access="public">
<cfargument name="nPracticeAreaID" type="numeric" required="false">

<cfargument name="lstFields" type="string" required="false">
<cfscript>

</cfscript>
</cffunction>
<cffunction name="getTypesByPracticeArea" returntype="query" access="public">
<cfargument name="nPracticeAreaID" type="numeric" required="false">
<cfargument name="nEditionID" type="numeric" required="false">
<cfscript>
return variables.oEditionDAO.getTypesByPracticeArea(argumentCollection=arguments);
</cfscript>
</cffunction>
</cfcomponent>
沒有什麼特別不尋常的。
的DAO看起來像

這是不尋常這裏的唯一的事情就是selectTypesByPracticeArea有一個lstFields違約與variables.lstSubEditionFields，但因爲它沒有被在該函數中使用，它不應該證明一個問題
所以index.cfm只是有
variables.stArgs = {};
variables.stArgs.nPracticeAreaID = request.parameters.nPublicationID;
variables.stArgs.nEditionID = request.parameters.nSubEdition;
variables.qTypes = application.stObj.oEditionBusiness.getTypesByPracticeArea(argumentCollection=variables.stArgs);
if(variables.qTypes["webtypeid"].IndexOf(JavaCast("int",2)) GTE 0 OR variables.qTypes["webtypeid"].IndexOf(JavaCast("int",3)) GTE 0){
request.parameters.bHasTypes = true;
}
上發生的錯誤if語句。它應該只接收包含webtypeid和typename的查詢，那麼它在哪裏認爲它從ID, BOOKID, EDITIONID, EDITIONNAME, PRACTICEAREALINK, PUBLISHED？我所能理解的是，它與前場混淆......但這沒有任何意義。
