CREATETABLEIFNOTEXISTStemp_random_numbers(random_numberINT); 1. 2. 3. CREATE TABLE IF NOT EXISTS:创建一个表,如果该表已经存在则不进行任何操作。 random_number INT:定义一个整数类型的列,用于存储随机数。 步骤2:生成随机数并插入临时表 接下来,我们使用循环和随机函数rand()来生成随机数并插入表中。可...
PostgreSQL 支持生成器函数 generate_series() 和内置的随机函数 RANDOM(),这使得任务变得更加简单:这段代码将生成10个随机的两位整数,并计算它们的总和。SQL Server 在SQL Server中,可以使用 NEWID() 或 CHECKSUM(NEWID()) 来生成随机数,结合 ABS() 函数确保结果为正数,并使用 TOP 来限制返回的...
(译者注:我将@NumberOfRNs 参数由100W改成1W,因为100W在测试中占用的时间过长,如果你喜欢,可以随意改动。) 下面是测试工具,为了我们期望的目标分布生成NURNs(非均匀分布随机数): -- Create random numbers for the selected distributionsSELECTTOP(@NumberOfRNs) RandomUniform = URN--,RandomPoisson = dbo.RN_...
生成随机数一般使用的就是random模块下的函数,生成的随机数并不是真正意义上的随机数,而是对随机数的一...
