我有一个函数可以循环查询并更新每个项目的数据库行。经过大约 7000 次迭代后,它抛出了内存不足错误 - Java 堆空间。这段代码有什么明显的问题吗?
<cfloop query=loc.fixItems>
<cfset loc.count = loc.count + 1>
<cfset var categoryName = loc.fixItems.categoryName>
<cfinvoke component="Item" method="updateCode"
itemId="#loc.fixItems.itemId#" code="#loc.fixItems.newCode#"/>
<!--- Increment counter for category --->
<cfif structKeyExists(categoryMap, categoryName)>
<cfset var inc = structFind(categoryMap, categoryName) + 1>
<cfset structUpdate(categoryMap, categoryName, inc)>
<cfelse>
<cfset structInsert(categoryMap, categoryName, 1)>
</cfif>
</cfloop>
在更新组件中:
<cffunction name="updateCode">
<cfargument name="itemId" type="numeric" required="yes">
<cfargument name="code" type="string" required="yes">
<cfset var loc = {}>
<cfquery name="loc.update">
update items
set code = <cfqueryparam value="#code#">
where id = <cfqueryparam value="#itemId#">
</cfquery>
</cffunction>
