sql語句中處理金額,把分換算成元

問題，sql語句中直接將金額/100返回的結果會有多個小數位。

select cate.cate_name as name,sum(acc.money)/100 as value from account as acc left join conCategory as cate on acc.cateCode=cate.cate_code 
group by cate_name

FORMAT(money/100,2)


select cate.cate_name as name,FORMAT(sum(acc.money)/100,2) as value from account as acc left join conCategory as cate on acc.cateCode=cate.cate_code 
group by cate_name

保留兩位小數，但是千位會有逗號，有逗號的話echarts之類的會不識別這個數據

truncate(money,2)

直接截取小數點后兩位，不進行四舍五入。

select cate.cate_name as name,truncate(sum(acc.money)/100,2) as value from account as acc left join conCategory as cate on acc.cateCode=cate.cate_code 
group by cate_name

OK
