Ok, I think still I am not clearly explained.

I have a table , with app_id, seq_id,seq_data.


It has values like the bellow
--------------------------------

One Record
---------------

app_id , seq_id , seq_data
21 , 1 , some_data ....
21 , 2 , some_data1...
21 , 3 , some_data2...

Second Record
-------------------
app_id , seq_id , seq_data
22 , 1 , second_data....


Third Record
----------------

app_id , seq_id , seq_data
23 , 1 , third_data....
23 , 2 , third_data1...


Now I need to exclue the app_id which has greater than 1 ie 2, 3 etc.. I need to extract app_id's which has seq_id only "1". What's the sql query i need to execute.

Thanks
