sequelize table without column 'id'

If you don't define a primaryKey then sequelize uses id by default.

If you want to set your own, just use primaryKey: true on your column.

AcademyModule = sequelize.define('academy_module', {    academy_id: {        type: DataTypes.INTEGER,        primaryKey: true    },    module_id: DataTypes.INTEGER,    module_module_type_id: DataTypes.INTEGER,    sort_number: DataTypes.INTEGER,    requirements_id: DataTypes.INTEGER}, {    freezeTableName: true});

If you want to completely disable the primary key for the table, you can use Model.removeAttribute. Be warned that this could cause problems in the future, as Sequelize is an ORM and joins will need extra setup.

const AcademyModule = sequelize.define('academy_module', {    academy_id: DataTypes.INTEGER,    module_id: DataTypes.INTEGER,    module_module_type_id: DataTypes.INTEGER,    sort_number: DataTypes.INTEGER,    requirements_id: DataTypes.INTEGER}, {    freezeTableName: true});AcademyModule.removeAttribute('id');

For a composite primary key, you should add "primaryKey: true" to all columns part of the primary key. Sequelize considers such columns to be part of a composite primary key.
