TypeError: argument callback must be a function when provided in Node js with a SQL query

Here is the code :

 application.post('/Modification/SaveEdit/:idd',function(req,res){
 var mem = req.body.memo;

 connection.query('UPDATE memos SET textMemo = ?',mem,'WHERE idMemo = ?',req.params.idd, function (error, results, fields){
        if (error) {
    console.log("error ocurred",error);
    res.send({
      "code":400,
      "failed":"erreur survenue"
    })
  }else{
    console.log('Resultats: ', results);
    res.send({
      "code":200,
      "success":"votre memo est bien modifié ! "
        });
  }
  });



});

i think it's the syntax of my query but i don't know how to write it correctly .

Here is the error :

TypeError: argument callback must be a function when provided

Thank's in advance !

I suspect that you might be using the connection.query incorrectly. Maybe check up on the docs for that (https://github.com/mysqljs/mysql#performing-queries). You are providing it with 5 arguments, but it should only have at most 3. Try the following:

application.post('/Modification/SaveEdit/:idd',function(req,res){
 var mem = req.body.memo;

 connection.query('UPDATE memos SET textMemo = ? WHERE idMemo = ?',[mem,req.params.idd], function (error, results, fields){
        if (error) {
            console.log("error ocurred",error);
            res.send({
                "code":400,
                "failed":"erreur survenue"
            })
        }else{
            console.log('Resultats: ', results);
            res.send({
                "code":200,
                "success":"votre memo est bien modifié ! "
            });
        }
    });
});
