Question

is it going to be faster if instead of doing

select * from users where id = 1 
or
delete from users where id = 1
or 
select count(*) from users

I would create a SP for it ?

Answer 1

Performance-wise, no it doesn’t make any difference.

Security-wise, it does made a difference. Using a sproc means you only need to grant execute permissions on the sproc, whereas the non-sproc approach would require permissions to be granted directly on the underlying table(s).

Network-traffic-wise – potential, slight/negligible difference. More applicable to larger statements whereby you either send the entire SQL statement across the wire or send just the sproc call. Pretty neglible overall.

Maintenance-wise – the sproc approach would allow you to (e.g.) tune a query without having to redeploy the whole application.

Something I’d be thinking is parameterising the query instead of using “hardcoded” values within an sql statement to support execution plan reuse.
