如果有用户通过where查询id=5000的时候,就会访问这个numberrange算法。根据上面的映射表直接查询得到分片的编号。 3.我们建表来测试一下 通过创建test_range表,我们插入了四条数据,分别是id=5000,10000000,12000000,20000000。可以看到5000存放在分片1上,10000000存放在分片2上,12000000存放在分片3上。这个和我们在partiti...
This is useful if you're dealing with percentages, as any value between0and1, rounded to two decimal places, can be thought of as a percentile. Generating Random Whole Numbers in Range We generally don't deal with floating-point numbers in the 0 to 1 range, though. So, let's look at...
* inRange(5.2, 4) * // => false * * inRange(-3, -2, -6) * // => true*///检查number是否在start和end之间,不包括end。如果没有指定end,则start被设置为end,而start为0。如果start比end大,则start和end互相交换以支持负区间functioninRange(number, start, end) {if(end === undefined) {...
