The characteristics of Oracle’s random function are as follows:<\/p>\n

    \n
  1. \u751f\u6210\u5747\u5300\u5206\u5e03\u7684\u968f\u673a\u6570\uff1aOracle\u7684\u968f\u673a\u51fd\u6570\u53ef\u4ee5\u751f\u6210\u5747\u5300\u5206\u5e03\u7684\u968f\u673a\u6570\uff0c\u786e\u4fdd\u6bcf\u4e2a\u53ef\u80fd\u7684\u503c\u51fa\u73b0\u7684\u6982\u7387\u662f\u76f8\u7b49\u7684\u3002
    \nGenerate random numbers with a uniform distribution: Oracle’s random function can create random numbers with a uniform distribution, ensuring that each possible value has an equal probability of occurring.<\/li>\n
  2. Oracle random function can generate random numbers of different data types, such as integers, decimals, and dates.<\/li>\n
  3. You can define the range of random numbers: Oracle’s random function allows you to specify the range of random numbers, such as generating random integers between 1 and 100.<\/li>\n
  4. Oracle random function can generate multiple random numbers at once, reducing the cost of queries.<\/li>\n
  5. Randomness controllable: Oracle’s random function can generate random numbers by setting a seed value, where the same seed value will produce the same random sequence.<\/li>\n<\/ol>\n

    It is important to note that Oracle’s random function is not a true random number generator, but rather generates pseudo-random number sequences based on a seed value. If a more random value is needed, other methods can be used, such as using random numbers generated by hardware devices as the seed value.<\/p>\n","protected":false},"excerpt":{"rendered":"
