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:
1 onkeyup= "if( !/^(((d|[1-9]d|[1-9]d[1-8])(.d+)?)|(999(.d{1,2})?))$/.test(this.value)){ 2 alertTip('不得超过1000,保留小数点后2位'); 3 this.value=''; 4 }"
后台接收参数后也要校验(略)
