Can't see a difference between queries 2 and 3. I can't tell which will run faster, you'll have to do that. Turn Statistics Time on and run them.

p.s. Why the meaningless aliases? They don't help readability, rather the opposite. If you're going to alias the tables, use something indicative of the table, eg from SY_DMS_AUTHORIZATION AS sda left outer join HR_JOBS AS hj
