Note that calling RAND(seed) with the same seed will start the same sequence and return the same number. To avoid this repeating pattern, you should always call RAND() without any seed and let the server to randomly pickup a sequence.
The tutorial exercise below shows some good examples on how to generate random numbers:
SELECT RAND(100), RAND(), RAND(); -- new sequence SELECT RAND(100), RAND(), RAND(); -- same sequence again SELECT RAND(), RAND(), RAND(); SELECT RAND(), RAND(), RAND(); GO 0.715436657367485 0.28463380767982 0.0131039082850364 0.715436657367485 0.28463380767982 0.0131039082850364 0.28769876521071 0.100505471175005 0.292787286982702 0.868829058415689 0.370366365964781 0.58334760467751 -- Random integer between 0 and 100 SELECT FLOOR(100*RAND()); SELECT FLOOR(100*RAND()); SELECT FLOOR(100*RAND()); SELECT FLOOR(100*RAND()); GO 68 29 20 82
