Question

我想将ticker=7203 JT Equity的每个EPSF1值除以EPSF1行的平均66,000值，我不知道如何合并这两个查询

select Date, Ticker,EPSF1 
from tblForecasts 
where EPSF1 is not null 
and Ticker='7203 jt equity'

select AVG(epsf1)

Answer 1

声明变量，将平均值存储在那里，然后在查询中使用它：

declare @avg decimal
select @avg = AVG(epsf1) from tblForecasts 

select Date, Ticker,EPSF1 / @avg
from tblForecasts 
where EPSF1 is not null 
and Ticker='7203 jt equity'

将值与总体平均值进行比较
