PL/SQL performance freak series – function calls from SQL overhead In my previous post I’ve shown and measured the performance loss on passing the parameters to and from procedure/function call inside PL/SQL code. In this article I’m about to reveal another bottleneck that is often forgotten and not so easy to overcome. Suppose you need to have some value calculated. The formula is straight matematical calculation but the… Read More

If the code that I’m calling is doing some DB operations and is not returning a value, it should be a procedure. There are however some situations, when I tend to… Read More
