There is inconsistencies in column names used in table and in query. Plus there are 5 records with rid=107. !!Please clear it a little and then someone can help.

Since your table column and query has few mismatch
I think use of distinct with group by is not required..

I have created a test query for your requirement in sort using 2 columns on basis of your requirement

"i want to run a query to get total rcom with no repeatation of mid"

Like this:

SQL

create table #temp(
rcom int,
mid int
)
insert into #temp(rcom,mid)values(0,108)
insert into #temp(rcom,mid)values(0,108)
insert into #temp(rcom,mid)values(100,109)
insert into #temp(rcom,mid)values(100,109)
insert into #temp(rcom,mid)values(100,110)
insert into #temp(rcom,mid)values(100,110)

select * from #temp

select SUM(rcom) as sum_rcom,mid from #temp group by mid

and Output is:

sum_rcom mid
0 108
400 109
400 110

Is this helpful..?
