Is there any way to achieve the following code?

I have an sql statement like..

Select
Res1,
Res2,
Res3,
Res4
from tbl1
where Res1=1
Group by Res2
Having Res4>0

I wanna hav the final column but that column is based on Res1 and Res3. The individual statement would be

Select
Res5
from tbl1
where Res1=1 and max(Res3)
Group by Res2
Having Res4>0

I wanna merge that Res5 into the first statement.

Res3 is the total value which can b got by executing the first statement.

I wanna do 开发者_运维问答like..

Select
Res1,
Res2,
Res3,
Res4
(Select
Res5
from tbl1
where Res1=1 and max(Res3)
Group by Res2
Having Res4>0)
from tbl1
where Res1=1
Group by Res2
Having Res4>0

But apperantly that is not correct.

How to achieve that?

The exact code would be

declare @noshow int, @target int; 
set @noshow=20;
set @target=1200;

select
CONVERT(VARCHAR(10), visit.regdate, 103) as 'Date',
datename(weekday, visit.regdate) as 'Day',
count(queueno) as 'Total_Served',
sum(case when datediff(second, starttime, nexttime)<= @target then 1 else 0 end) as 'Less_Target',
isnull((sum(case when datediff(second, starttime, nexttime)<= @target then 1 else 0 end)*100)/count(queueno),0) as 'Less_Target_Per',
sum(case when datediff(second, starttime, nexttime)> @target then 1 else 0 end) as 'More_Target',
isnull((sum(case when datediff(second, starttime, nexttime)> @target then 1 else 0 end)*100)/count(queueno),0) as 'More_Target_Per',
isnull(CONVERT(varchar(6), avg(datediff(second,nexttime,endtime))/3600)+ ':' + RIGHT('0' + CONVERT(varchar(2), (sum(datediff(second,nexttime,endtime)) % 3600) / 60), 2)+ ':' + RIGHT('0' + CONVERT(varchar(2), sum(datediff(second,nexttime,endtime)) % 60), 2),0) as 'Avg_Serving_Time',
isnull(CONVERT(varchar(6), max(datediff(second,starttime,nexttime))/3600)+ ':' + RIGHT('0' + CONVERT(varchar(2), (max(datediff(second,starttime,nexttime)) % 3600) / 60), 2)+ ':' + RIGHT('0' + CONVERT(varchar(2), max(datediff(second,starttime,nexttime)) % 60), 2),0) as 'Max_Waiting_Time',
CONVERT(VARCHAR(26), getdate(), 108) as 'Cus_Arrival'

group by regdate
having sum(case when datediff(second, starttime, nexttime)> @target then 1 else 0 end) >0

Ignore the where clause. It is too long.

I wanna replace Cus_Arrival with the second statement.

It is actually the arrival time for the Max_Waiting_Time.

I assume you are using MS SQL Server.

Select
    Res1,
    Res2,
    Res3,
    Res4
from tbl1
where Res1=1
Group by Res2
Having Res4>0

is not valid.

You can not select columns that are not part of the group by.

Read about group by here http://msdn.microsoft.com/en-us/library/ms177673.aspx

Each table or view column in any nonaggregate expression in the list must be included in the GROUP BY list:
