SQL Node.js 上的 Server 2008 与 Sequelize

Question

我是新来的！

我正在尝试使用 sequelize 在 MS SQL Server2008 上进行查询，但出现此错误：

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.

我已经安装了这个模块： -续集； - 乏味;

我的连接没有问题，只有这个查询：

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

我能做什么？我没有任何名为 id

的列

这是我的 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),
}

默认情况下，sequelize 会添加一个名为 id 的主键，如果你自己什么都不做的话。

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

也可以有没有主键的模型，但我不推荐这样做
