query produces ambigious column reference when using attributes and include

The following example fails with

Unhandled rejection SequelizeDatabaseError: column reference "name" is ambiguous

var S = require('sequelize');

var sequelize = new S('seq_test', 'postgres', '', {
//var sequelize = new S('seq_test', 'passwd', '', {
    host: 'localhost',
    dialect: 'postgres',
    pool: { max: 15, min: 0, idle: 10000, },
    define: {  },
});

var User = sequelize.define('User', {
    name: { type: S.STRING(50), allowNull: true},
    pass: { type: S.STRING(50), allowNull: true},
});
var Foo = sequelize.define('Foo', {
    name: { type: S.STRING(50), allowNull: true},
    pass: { type: S.STRING(50), allowNull: true},
});

User.belongsTo(Foo, {});

sequelize.sync()
.then(function (){
    User.findAll({
        //raw: true,
        attributes: [  [ S.col('name'), 'username' ]   ],
        include: [
            {   model: Foo,
                attributes: [ [ S.col('name'), 'fooname' ] ],
            },
        ],
    });
});

sql produced.

SELECT 
  "name" AS "username", 
  "Foo"."name" AS "Foo.fooname" 
FROM "Users" AS "User" 
LEFT OUTER JOIN "Foos" AS "Foo" ON "User"."FooId" = "Foo"."id";

as you can see the S.col(‘name’) in the User relation did not prefix the column with the table alias.

If there is no “attributes” section, and all columns are used then columns from the user relation are prefixed.

I had the same problem, and I could fix this easily by enabling the flag subQuery to true

User.findAll({
        //raw: true,
        attributes: [  [ S.col('name'), 'username' ]   ],
        include: [
            {   model: Foo,
                attributes: [ [ S.col('name'), 'fooname' ] ],
            },
        ],
        subQuery: true, <-------------------------------
    });

Try to add the table name on your Sequelize.col and use it on its singular form. Also try to add “->” if it is nested.

sequelize.sync().then(function() {
    User.findAll({
        attributes: [[ Sequelize.col('User.name'), 'username' ]],
        include: {
            model: Foo,
            attributes: [[ Sequelize.col('User->Foo.name'), 'fooname' ]],
        }
    });
});```
