knex .select('*') .from('users') .join('accounts', function () { this.on(function () { this.on('accounts.id', '=', 'users.account_id'); this.orOn('accounts.owner_id', '=', 'users.id'); }); }); 

knex .select('*') .from('users') .join('accounts', function () { this.on(function () { this.on('accounts.id', '=', 'users.account_id'); this.orOn('accounts.owner_id', '=', 'users.id'); }); });
