Question

This is my table structure

id   state     city   lat    lon
1     erer      wer    34     34
2     ffff      dfd    44     33
1     fds       rw     0      45

Using this, I have to retrieve the data without duplicates from the above table. If I have to retrieve data with id 1 and 2, I used Group by id. Now I also have to check one more condition, whether the lat > 0.

select *
  from table
 group by id and lat > 0  

But still data with 0 is also being retrieved.

Answer 1

Try,

select *
from table
WHERE lat > 0 
group by id
