    ...Personally, I love playing with recursive CTEs, almost as much as I like being naughty, just to figure out how they work. 😛

    I always hear people saying "stay away from recursive CTEs because they're slow" ...

    Play is an excellent way to learn - I love to play with the problems folks post on here (far too little time these days). Here's a few examples of rCTE's to whet your appetite:

    Paul White's Super-fast DISTINCT

    Calculating interest rate

    Handshaking

    Running total with a twist

    Sequence-numbering groups

    Calculate volume percentages

    Have fun!

    Cheers
