错误描述：会员充值明细页面点击删除充值单，提示删除失败
错误日志：
【错误SQL语句】：update t_member_product set amount=amount-(select amount from t_member_chargproduct where document_id='HC180820002' and product_id=t_member_product.product_id) ,amount_remain=amount_remain-(select amount from t_member_chargproduct where document_id='HC180820002' and product_id=t_member_product.product_id) where member_id=(select member_bid from t_member_charg where document_id='HC180820002') and product_id in (select product_id from t_member_chargproduct where document_id='HC180820002' and amount>0) and paysort='计次消费'
错误原因：历史版本导致会员充值允许充重复的项目和货品，删除充值单据时，后台子查询：一个充值单不会存在两条重复的项目编号或者货品编号。
解决方案：
查询重复项目和货品
select max(id) as id,member_id,ritem_id from t_member_ritem group by member_id,ritem_id HAVING count(ritem_id)>1
select max(id) as id,member_id,product_id from t_member_product group by member_id,product_id HAVING count(product_id)>1
select max(id) as id,document_id,ritem_id from t_member_chargritem group by document_id,ritem_id HAVING count(ritem_id)>1
select max(id) as id,document_id,product_id from t_member_chargproduct group by document_id,product_id HAVING count(product_id)>1
注意：删除前请查询重复项目和货品是否有疑问
