Knex migration failed with error: The query is empty

Question

我按照他们的迁移指南将 knex 从 0.21 更新到 0.95，现在我在 CI 运行 npx knex migrate:latest

时收到此错误

migration file "20191104160706_migrate-appsflyer_customers.js" failed
migration failed with error: The query is empty
    at createQueryBuilder (/home/circleci/backend/node_modules/knex/lib/knex-builder/make-knex.js:313:26)

但迁移文件包含查询的

async function up (knex) {
  // language=Postgres
  const { rows } = await knex.raw(`
    SELECT * FROM appsflyer_customer;
  `)
  const mappedRows = rows.map(row => ({
    user_id: row.user_id,
    advertising_id_type: 'appsflyer',
    advertising_id: row.appsflyer_device_id
  }))
  await knex('device_advertising_association')
    .insert(mappedRows)
}
async function down (knex) {
  await knex.raw(`
    DELETE FROM device_advertising_association WHERE user_id NOTNULL;
  `)
}
module.exports = {
  up, down
}

任何帮助将不胜感激，因为我对错误消息一无所知

Answer 1

所以我收到这个错误是因为 Knex 0.95 引入了一个新功能 https://github.com/knex/knex/pull/4289 因此如果将空数组传递给 insert 它将抛出一个之前不存在的错误

因为我们没有使用 table 它是空的，上面的迁移试图插入一个空数组，它在 CI 上抛出错误所以我基本上处理了异常使用 try-catch 块并得到解决

所以请仔细查看更改日志
