我正在尝试为客户端修复一些代码。问题是，我们有.CSV文件，这些文件是用ColdFusion编写的，但是由于某些原因，重复项会不断生成，即使其中有nameConflict = "Overwrite"。我发现nameConflict甚至可能无法与cffile action="write"一起使用，我怎样才能在每次生成重复文件名的末尾添加一个升序号？ CSV文件只显示客户续订信息。
<cfif arguments.isRenewal EQ "Y">
<cffile action="write" file="#filename#" nameconflict="overwrite" output='"Capital","#custName#","","#getCustomer.fname#","#getCustomer.lname#","#getCustomer.serviceAddress1#","#getCustomer.serviceAddress2#","#getCustomer.serviceCity#","#getCustomer.serviceState#","#getCustomer.serviceZip#","#cleanPhone#","#cleanMobilePhone#","#getCustomer.email#","#getCustomer.billingAddress1#","#getCustomer.billingAddress2#","#getCustomer.billingCity#","#getCustomer.billingState#","#getCustomer.billingZip#","0","N/A","Electric","#getCustomer.sdi#","#getCustomer.sdi#","#getProvider.utilityCode#","#getOffer.rateSchedule#","#getOffer.productCode#","#getOffer.rate/100#","kWh","$","#getOffer.rackRateName#","#DateFormat(now(), "yyyy-mm-dd")#","#startDate#","#getOffer.term#","Internet","","","","","","","","","","","","","M2M","#getOffer.evergreenProduct#","Y"'>
<cfelse>
<cffile action="write" file="#filename#" nameconflict="overwrite" output='"Capital","#custName#","","#getCustomer.fname#","#getCustomer.lname#","#getCustomer.serviceAddress1#","#getCustomer.serviceAddress2#","#getCustomer.serviceCity#","#getCustomer.serviceState#","#getCustomer.serviceZip#","#cleanPhone#","#cleanMobilePhone#","#getCustomer.email#","#getCustomer.billingAddress1#","#getCustomer.billingAddress2#","#getCustomer.billingCity#","#getCustomer.billingState#","#getCustomer.billingZip#","0","N/A","Electric","#getCustomer.sdi#","#getCustomer.sdi#","#getProvider.utilityCode#","#getOffer.rateSchedule#","#getOffer.productCode#","#getOffer.rate/100#","kWh","$","#getOffer.rackRateName#","#DateFormat(now(), "yyyy-mm-dd")#","#startDate#","#getOffer.term#","Internet","","","","","","","","","","","","","M2M","#getOffer.evergreenProduct#","N"'>
