How to write a single query for the above statement.

Answer 1

select value from students where coll_Id in (1,2,3,4,5,6,7,8,9,10);

EDIT: // see question comment by @t-clausen.dk

If you’re always dealing with ranges you could use

select value from students where coll_Id between 1 and 10;

which is equivalent to

select value from students where coll_Id >= 1 and coll_id <= 10;
