To understand what’s happening, imagine that there is a long list of random numbers that the computer chooses from. To get the answer correct to the above SQLBox, set the seed to. Change the seed value (.123) in the setseed function above and notice that it will now choose a different random value but maintain that on multiple runs. Notice that it returns a random result as expected, but unlike above, it’s the same random result every time. Try running the following query multiple times: To do so we want to set the starting seed (always between 0 and 1) for the random number generator. Often you want random data but would like it to be the same random data every time it’s run.
