Question

Answer 1

ok, this may be a little oversimplified (and possibly incomplete):

With a stored procedure:

1. you do not need to transmit the query to the database
2. the DBMS does not need to validate the query every time (validate in a sense of syntax, etc)
3. the DBMS does not need to optimize the query every time (remember, SQL is declarative, therefore, the DBMS has to generate an optimized query execution plan)
