Analogous to doing a JOIN in the DBMS vs. This saves shuffling large amounts of data off to the client only to have it send a trickle of info back (or none at all!). Occasionally the query plan that is generated is sub-optimal.Ī) If you are running the same SQL over and over - and the SQL adds up to many KB of code - replacing that with a simple "exec foobar" can really add up.ī) Stored procs can be used to move procedural code into the DBMS. WARNING Cached query plans are not a performance panacea. There are some caveats and cases in which this isn't the case, so you'll need to test on your target DBMS.Īlso, more and more DBMS allow you to provide optimizer path plans (abstract query plans) to significantly reduce optimization time (for both ad hoc and stored procedure SQL!!). Most DBMS' (the latest editions) will cache the query plans for INDIVIDUAL SQL statements, greatly reducing the performance differential between stored procs and ad hoc SQL. Stored procedures will, generally, store this in memory so you can avoid this overhead. It is not unknown for very complicated SQL to have distinct, measurable (I've seen a complicated query take 10+ seconds just to generate a plan, before we tweaked the DBMS) latencies due to the optimizer trying to figure out the "near best" execution plan. If you have many JOINs the permutations can grow quite unmanageable (modern optimizers have limits and cut-offs for performance reasons). Not very noticeable at all on the modern CPU, but if you are sending a single SQL statement that is VERY large eleventy-billion times a second, the parsing overhead can add up. interpreted code, except on a very micro level. ![]() Pre-parsed SQL - similar benefits to compiled vs. The historical performance benefit of stored procs have generally been from the following (in no particular order): So, I have no particular axe to grind in this (sometimes) holy war. I've been a Sybase ASE, MySQL, and SQL Server DBA on-and off since for almost a decade (along with application development in C, PHP, PL/SQL, C#.NET, and Ruby).
