Dear all,

Just want to know which join is better for querying data faster.

I have 2 tables A ( 70 GB ) & B ( 7 MB )

A has 10 columns & B has 3 columns.Indexes exist on both tables's ids.

select p.* from table A p, B q where p.id=q.id

or

select p.* from table B q , A p where q.id=p.id


Thanks
