对数据进行一些基本操作（四）

//查询语句
var selAll='select * from list';
//根据post的id查询
var selId='select * from list where id=?';
//插入数据
var addData='insert into list (u_name,u_phone) values (?,?)';
//删除数据
var delData='delete from list where id=?';
//更新数据
var upData='update list set u_name=?,u_phone=? where id=?'
//更新数据
router.post('/edit',function(req,res,next){
    var params=req.body;
    console.log(params)
    pool.getConnection(function(err,suc){
        suc.query(upData,[params.name,params.phone,params.id],function(err,result){
            console.log(err)
            console.log(result)
            if(result){
                result={
                    code:200,
                    msg:'更新数据成功'
                }

            res.json(result);
            suc.release()
        })

//删除数据
router.post('/del',function(req,res,next){
    var params=req.body;
    console.log(params)

                }
            }
            res.json(result);   //响应返回json数据
            suc.release();  //关闭数据库连接
        })
    })

//响应post
router.post('/list', function(req, res, next) {
    var id=req.body.id; //通过req的body拿到post的id
    pool.getConnection(function(err,suc){
        suc.query(selId,[id],function(err,result){
