Calling conn.end() to release a pooled connection is deprecated. In next version calling conn.end() will be restored to default conn.end() behavior. Use conn.re

我的代码：

 exports.query = function(sql,data,callback){
  var mym = false;
  var mycallback;
  var mydata;
  if (typeof data === 'function'){
    mycallback = data;
    mydata = [];
  }
  else{
    mycallback = callback;
    mydata = data;
  };
  
  mym = sql.split(';').length > 1;  //有多个sql了

  pool.getConnection(function(err,conn){
    if(!err){
      config.debug || console.log(sql);
      conn.query(sql,data,function(err,rows){
        conn.end();
        if(!err){
          if(mycallback) mycallback(null,rows);  
        }
        else{
          if(mycallback) mycallback(err,null);
        }
      });
    }
    else{
      if(mycallback) mycallback(err,null); 
    }
  });
};
