IN vs. OR on performance

[Oscar]

Hi all-

I want to know what the difference between IN and OR is under the hood.

select * from dummy_table where id in (2, 3, 4, 5, 6, 7);

select * from dummy_table where id=2 or id=3 or id=4 or id=5 or id=6 or
id=7;

I run the query sql on the test schema, it seems that there is no
performance difference between these two pieces of sql.

Thank you,
