Which one perform better for the same job : Oracle Function or Oracle View

Jan 01 2007April 2, 2007

Ok lets try and see, as usual :)

Code listing 35 : Oracle View or Function performs better for the same job

Conclusions; same amount of I/O to do the same thing but view option used less latching and ran faster(older releases will show a larger disparity between the run times). Again time to remember the “Universal mantra on data intensive processing” : don’t use plsql when plain old sql will do it for you ;)

Testing Information : the scripts mentioned are tested on Oracle Database 10g Express Edition Release 10.2.0.1.0
