Selecting a Group of records based on a single Record Value

Question

Let us consider we I have a table as follows

I need to select the records with same "group_id" s where at least anyone record's "type" is equal to 1.

The expected result set must be like

Answer 1

This should work:

select * from table where group_id in
(
    select group_id from table where type = 1
)

You can also try join instead of in

select a.* from table a
join 
(
   select group_id from table where type = 1
) b on b.group_id = a.group_id
