}, { transaction: t }),
queryInterface.addColumn('table_name', 'field_two_name', {
type: Sequelize.STRING,
}, { transaction: t })
])
})
},

return queryInterface.sequelize.transaction((t) => {
return Promise.all([
queryInterface.removeColumn('table_name', 'field_one_name', { transaction: t }),
queryInterface.removeColumn('table_name', 'field_two_name', { transaction: t })
