数据库长度比例(SqlServer字段长度和比例指什么意思?)

NUMERIC(P,S) P的默认值是：38 S的默认值是：-84~127

numeric(a,b)函数有两个参数，前面一个为总的位数，后面一个参数是小数点后的位数，例如numeric（5,2）是总位数为5，小数点后为2位的数，也就是说这个字段的整数位最大是3位。

前台传来的参数为格式不对

添加前台文本框进行校验:

 onkeyup= "if( !/^(((\d|[1-9]\d|[1-9]\d[1-8])(\.\d+)?)|(999(\.\d{1,2})?))$/.test(this.value)){
                            alertTip('不得超过1000,保留小数点后2位');
                            this.value='';
                        }"

后台接收参数后也要校验(略)
