Adding Conditions In The ON Clause Of A JOIN

Hi Faculties,
I have two queries which give me the same output.


-- Query 1
SELECT prod.name, cat.name
FROM products prod INNER JOIN categories cat
ON prod.category_id = cat.id
WHERE cat.id = 1;

-- Query 2
SELECT prod.name, cat.name
FROM products prod INNER JOIN categories cat
ON prod.category_id = cat.id AND cat.id = 1;


The first query uses the WHERE clause and the second one has all the
conditions in the ON clause. Is there anthing wrong with the second
approach in terms of performance? Please suggest.


Thanks in advance
Jackal
