Cursors Without Performance Penalties

  • Comments posted to this topic are about the item Cursors Without Performance Penalties

  • Whew!!! Nice one, Steve!! You had me going there!  I was thinking that I should plan on retiring sooner than I really wanted because even the cursors in Oracle are still slower than good, solid, set-based code.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.

  • Good one. But sometimes I wish there was a better row by row method available for those few times when there appears to be no other option.

  • I had forgotten what day it is.

  • Glad you enjoyed it. Trying to come up with something to "get" you is always a fun challenge.

  • You got me too but it would be a good idea to make it act more like PL/SQL I see a few Oracle applications are migrating to MS SQL and it would make things easier.

  • The link in the whitepaper seems to be broken :(.

    The above is all just my opinion on what you should do. 
    As with all advice you find on a random internet forum - you shouldn't blindly follow it.  Always test on a test server to see if there is negative side effects before making changes to live!
    I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.
