Hi I have two tables
create table Students (StudentID int not null , Name nvarchar(20))
insert into Students values (101111 , 'XYZ'),
(101112 , 'Ben') ,
(101113 , 'Kate'),
(101114 , 'Andy')
Create Table Subscriptions (StudentID int , Subscriptions int)
insert into subscriptions values ( 101111, 3),
(101111,10),
(101112, 8),
(101113 , 4),
(101112,12),
(101114 , 3),
(101114,5)
-- query
select s.StudentID , sum(SS.subscriptions) subscriptions from students s join Subscriptions SS
on s.StudentID= ss.StudentID
group by s.StudentID
having sum(SS.subscriptions) > 10
-- Result
studentId Subscriptions
10111113 13
10111220 20
Now I need to get only the studentId whose subscriptions are > 10 into a new table. The table has only one column StudentID

First step: write a query to identify studentIds where subscription > 10. Can you do that bit?

Perhaps I should have read more closely, sorry. Have you created the new table yet?

Out of interest, why would you want to store these in a table? If your data changes, this would mean that your table of student ID's would be stale, and incorrect. Would a view meet your needs better?
What should happen if a student has more than 10 subscription, and later doesn't? What happens if you run this script again, should you put everyone's ID in there again 9meaning duplication, and without an ID, you have no way of disguising them?
This is the simple answer, but consider what i've said above.CREATE TABLE YourNewTable (StudentID);
GO
INSERT INTO YourNewTable
SELECT s.StudentID
FROM students s
JOIN Subscriptions SS ON s.StudentID= ss.StudentID
GROUP BY s.StudentID
HAVING SUM(SS.subscriptions) > 10;

Excuse my typos and sometimes awful grammar. My fingers work faster than my brain does.

Yes, I have created and I got the solution. Thanks for helping me all the time
