用户定义函数(UDF)分类  SQL SERVER中的用户定义函数(User Defined Functions 简称UDF)分为标量函数(Scalar-Valued Function)和表值函数(Table-Valued Function).其中表值函数又分为Inline table-valued functions和Multistatement table-valued functions. 用户定义函数(UDF)在 SQL Server 中发挥重要的作用.用户定义函数可以用于执行复杂的逻辑

  提到上述的概念之前,首先想说说javascript中函数的隐含参数:arguments Arguments 该对象代表正在执行的函数和调用它的函数的参数. [function.]arguments[n] 参数 function:选项.当前正在执行的 Function对象的名字. n:选项.要传递给 Function对象的从0开始的参数值索引. 说明 Arguments是进行函数调用时,除了指定的参数外,还另外创建的一个隐藏对象.Arguments是一个类似数组但不是数组的对象,说它类似数组是

Object.prototype.create=(function(){ if(Object.prototype.create){return Object.prototype.create}else{var F=function(){};return function(proto){F.prototype=proto;return new F();}} })()

MySQL获取随机数   如何通过MySQL在某个数据区间获取随机数? MySQL本身提供一个叫rand的函数,返回的v范围为0 <= v < 1.0. 介绍此函数的MySQL文档也介绍道,可以通过此计算公式FLOOR(i + RAND() * (j – i)),获取i <= v < j的随机数字v. 附文档链接:http://dev.mysql.com/doc/refman/5.0/en/mathematical-functions.html#function_rand 为了书写
