Simple Pl/SQL query -

Question

Hi,
This might be a simple question, I am new to Pl/SQL ,
I have a table which consists of two columns deal_id and freq.
for each deal_id there might be number of freq. The table something looks similar ltoo this,
deal_id freq
10 1.1
10 1.2
12 1.1
12 1.2
14 1.1
14 1.2
14 1.3
16 1.5
16 1.5
Now if a deal_id selected has freq 1.1 and 1.2 , it should display output has 'MA only'
if a deal_id selected has freq other than 1.1 and 1.2 , it should display 'Not MA'
else if it has like deal_id 14 should display . 'Both Ma and Non MA'
I wrote a query like this,
select
deal_id
, case
When Freq In (1.1 , 1.2) Then 'MA Only'
When Freq Not in (1.1 , 1.2) Then 'Non-MA Only'
Else 'Both Ma and Non-Ma'
End freq_dt
from sample_Table
where ia.deal_id= '14'
O/P i get is
deal_id freq_dt
14 MA only
14 MA only
14 Non MA only
But i should get O/p like
deal_id freq_dt
14 Both MA and Non Ma
Any help will be greatlt appreciated.
Thanks,
Vin

Thanks Guys, for all your valuable suggestions.
These forums are helping me a lot.
Ok, back to the question, after going thru all the posts, i worked out on the query at work for a while and edited it something like this,
Select
case
when count(distinct freq_dt)>1 Then 'Both MA and Non-MA only'
Else <......>(pl refer below)
end status
from
(select
ia.deal_id
, case
when Freq In (851.0125, 851.5125, 852.0125, 852.5125, 853.0215) Then 'MA Only'
When Freq Not in (851.0125, 851.5125, 852.0125, 852.5125, 853.0215) Then 'Non-MA Only'
Else 'Both Ma and Non-Ma'
End freq_dt
from repl_site_freq ia
where ia.deal_id='65'
No worries, I know the query looks like useless, but I am working, I am new to Oracle,
and what i have done is performed a distinct count on the subquery.
Now if count >1 , i mean there is MA and Non-MA so it displays both MA and Non MA. Its working fine.
But now if count = 1, i mean if the whole subquery table has either MA or NOn-MA , then how can i catch that .
I mean if count =1, O/p shud be MA only if all are MA
and NON-MA if all are Non-MA.
Now I want to put this query in the else statement above
select st from
select
ia.deal_id
, case
when Freq In (851.0125, 851.5125, 852.0125, 852.5125, 853.0215) Then 'MA Only'
When Freq Not in (851.0125, 851.5125, 852.0125, 852.5125, 853.0215) Then 'Non-MA Only'
Else 'Both Ma and Non-Ma'
End st
from repl_site_freq ia
where ia.deal_id='32434'
A where rownum < 2
since this subquery just returns count=1, and i want to display the first item in first row of first column which can be either MA or NOn-MA
when i put the above quesry in else, it returns me some error, like groupby missing.
ANy help will be greatly appreciated.
Thanks,
Vin
