问题描述：
U821的数据库升级到T3标准版，财务帐套可以升级，进销存不能升级。
问题回复：
查看您的数据，是由于accinformation表里存在多余记录引起的，请备份账套，然后执行以下语句： delete ufdata_666_2005..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2006..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2007..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2008..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2009..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2010..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2011..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2012..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2013..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2014..accinformation where cname='idefaultzhbvrate' delete ufdata_666_2015..accinformation where cname='idefaultzhbvrate' 执行之后再进行升级即可。
