    Hello,

     

    what are the algorithm behind the new DBMS_RANDOM module?

    Mersenne Twister

    Sobol

    Linear congruential generator

    Linear feedback shift Register

     

    just to list some  RNGs.

     

    Are they vectorized?

    Hi Olaf. I don't know those details off the top of my head, but can say that this is essentially an interface ​wrapper around the existing SYSFUN.RAND, for application compatibility
