SQL Server 2008 on Node.js with Sequelize

Question

I'm new here !

I'm trying to do a query on a MS SQL Server2008 with sequelize, but I get this error:

Unhandled rejection SequelizeDatabaseError: Invalid column name 'id'. at Query.formatError (C:\xampp\htdocs\Lavori\Bit_Sense\API_BS\node_modules\s equelize\lib\dialects\mssql\query.js:217:10) at Request.userCallback (C:\xampp\htdocs\Lavori\Bit_Sense\API_BS\node_module s\sequelize\lib\dialects\mssql\query.js:66:25) at Request.callback (C:\xampp\htdocs\Lavori\Bit_Sense\API_BS\node_modules\te dious\lib\request.js:30:27) at Connection.STATE.SENT_CLIENT_REQUEST.events.message (C:\xampp\htdocs\Lavo ri\Bit_Sense\API_BS\node_modules\tedious\lib\connection.js:283:29) at Connection.dispatchEvent (C:\xampp\htdocs\Lavori\Bit_Sense\API_BS\node_mo dules\tedious\lib\connection.js:752:59) at MessageIO.

I've installed this module: - sequelize ; - tedious ;

I haven't problem on the connection, only with this query:

db.KEY_ARTI.findAll({
  where:{
	      CACODICE: cacodice
	    }
	}).then(function(data) {
		res.send(data);
	});

What can I do ? I haven't ANY column called id

Here is my table:

var Sequelize = require('sequelize');
var settings = global.settings.databases.DATABASE;
var errors = global.errors;
var utilities = global.utilities; 

var sequelize = new Sequelize(settings.schema, settings.username, settings.password, {
      dialect: settings.dialect,
      host: settings.host,
	  port: settings.port, /* BISOGNA USARE LA DYNAMIC PORT */
      logging: function (str) {
          if(settings.log)
            console.log("querylog: "+str.replace("Executing (default):", "") );
      },
    });

sequelize.authenticate().then(function(err) {
    if (!!err) {
      console.log('Database '+settings.schema+' Connection Error:', err)
    } 
    else {
      console.log('Database '+settings.schema+' Connected')
    }
});

exports.sequelize = sequelize;

/*
 * KEY_ARTI
 */
exports.KEY_ARTI = sequelize.define('KEY_ARTI', {
	CACODICE: Sequelize.CHAR(20),
	CADESART: Sequelize.CHAR(40),
}

here it's saying in Invalid column name 'id'. Can you check about this. Or post the code for review. — Janny

I added in the answer the code, and I'm sure that I have the Object, because if I do a console.log(db.KEY_ARTI) and isn't undefined or null — Marco

By default, sequelize will add a primary key called id, if you don't do anything yourself.

sequelize.define('model', {}); // Adds an id key

sequelize.define('model', {
  name: {
    primaryKey: true
    type: Sequelize.STRING
  }
}); // Doesn't add an id, because you already marked another column as primary key

It is also possible to have a model without a primary key, but I wouldn't recommend this

Yes I find it ! I added the primary key, but, as you said, you can remove the attributes
