Home -> Community -> Mailing Lists -> Oracle-L -> Re:pl/sql is INTERPRETED?
Lisa,
It is both true & false at the same time. Obviously any anonymous blocks you submit to the database are fully interpreted. PL/SQL that you store in the database as procedures, functions, and packages get partially compiled into a p-code. This makes the code ready for execution, but retains a modular design so that if your DBA reloads catproc your code is not totally destroyed. Where I think PL/SQL buys us a lot of performance is in reducing the communications outside of the database that is otherwise needed. There's no JDBC driver or other miscellaneous mess (like SQL*Net) required. It's all handled inside the kernel. Now the bad part about PL/SQL that Java handles better is platform independence. You can run Java on your client, the apps server or database without a problem. PL/SQL on the other hand must be run in the database.

Can this be true? How can this be? If it's optimized to manipulate data within the database, how can it be fast if it's interpreted (like that slow poke, Java)?
I see this on Connor's website www.oracledba.co.uk under explicit/implicit cursors, under pl/sql. What on earth?
Can someone elaborate, namely, Connor?? Please help me understand this... My "green" may be showing, but my gosh.
