2、TRUNC(A/B,2)TRUNC()函数是不会将计算结果进行四舍五入的，如果所需要的值不需要进行四舍五入，就可以选择这个函数，可以有一个参数，也可以有两个参数；如果有两个param，第一个是你的计算表达式，第二个是需要保留的小数位数。3、TO_CHAR(A/B,‘FM99990.99’)TO_CHAR()是一个格式化...
语法:CEIL(number)、FLOOR(number)、ROUND(number, decimal_places) 返回值:number向上取整、向下取整或四舍五入到指定的小数位数 7、比较函数(GREATEST、LEAST) 语法:GREATEST(value1, value2, …)、LEAST(value1, value2, …) 返回值:多个数值中的最大值或最小值 ...
For example, users can use the relative date filter to show only sales data that's happened within the last 30 days (calendar months). The default filter is "Today". You can specify a relative date period as either an explicit number of past or future time units (for example, 2 years...
