ROUND SQL

Question

我想這樣做，請

select round(9.100000, 3) from dual 

結果= 9.100

select round(12679.1000001, 3) from dual 

結果= 12679.100

感謝

Answer 1

你可以做到這一點to_char方法：

select to_char(9.100000, '999.999') from dual 

select to_char(12679.1000001, '99999.999') from dual 

例有一張桌子，而不是常數值：

with temp as (
    select 9.100000 as num from dual 
    union 
    select 12679.1000001 as num from dual 
    union 
    select -20.2356 as num from dual 
) 
select to_char(num,'99999.999') from temp
