create table numbers
(
n1 int,
n2 numberic(5,0),
n3 numberic(4,2)
)
go
insert numbers values(1.5,1.5,1.5)
select *
from numbers
go
答案是1、2和1.50的结果集，我想问的是那个2怎么来的？
------解决方案--------------------
四舍五入
- SQL code
select cast(1.4 as numeric(5,0)) as num1,cast(1.5 as numeric(5,0)) as num2/**num1 num2--------------------------------------- ---------------------------------------1 2(1 行受影响)**/
