这样:
select
t.[origin-destination],t.[SH/LANE/MOT] /(select count(1) from ['TMS$'] ) AS PERCENTAGE
FROM (代码1) t
group by [origin-destination],t.[SH/LANE/MOT]
having t.[SH/LANE/MOT] /count(*) <= 0.01
注:两个count都是int,相除会没有小数部分,所以应该都给转成带小数的数。
cast as numeric(10,4) 。
SQL中除法运算的实现
R(X,Y)÷S(Y,Z)的运算用结构化语言SQL 语句可表达为下列形式:
select distinct R.X from R R1
where not exists
(
select S.Y from S
where not exists
(
select * from R R2
where R2.X=R1.X and R2.Y=S.Y
)
)
