Question

我在SQL下面会返回结果，但我希望价格四舍五入到小数点后6位。

select opt.blo,
  opt.premiumcurrency,
     case
      when opt.structurename is not null then opt.basemarketprice /100
        when pct = 1 then opt.basemarketprice /100
        when pct = 2 then opt.termmarketprice / opt.notional
        when opt.notionalcurrency = opt.premiumcurrency  then opt.basemarketprice /100
        else opt.termmarketpricepercent /100
    end as round(price,6)
from interafce opt

当我在下面添加时，它会给我错误

ORA-00923：找不到FROM关键字

感谢您的帮助。

Answer 1

case需要进入round()。您将该函数与别名混淆：

 round(case when opt.structurename is not null then opt.basemarketprice /100
            when pct = 1 then opt.basemarketprice /100
            when pct = 2 then opt.termmarketprice / opt.notional
            when opt.notionalcurrency = opt.premiumcurrency  then opt.basemarketprice /100
            else opt.termmarketpricepercent /100
       end, 6) as roundedPrice

Answer 2

以圆形（价格，6）结束不起作用。您将列别名为＆＃34; round（price，6）＆＃34;

宁愿做一个

select .....
....
when opt.structurename is not null then round(opt.basemarketprice /100,6)
        when pct = 1 then round(opt.basemarketprice /100,6)
        when pct = 2 then round(opt.termmarketprice / opt.notional,6)
        when opt.notionalcurrency = opt.premiumcurrency  then round(opt.basemarketprice /100,6)
        else round(opt.termmarketpricepercent /100,6)
    end as rounded_price
