【问题描述】：

我尝试使用 Sequelize 混合表格，但不知道如何操作。

SELECT count(*) as counts
FROM
  (SELECT * FROM board order by id desc limit 10) as board
WHERE board.login_id = 1234

我如何在 Sequelize 中表示这一点

【问题讨论】：

能否也添加为counts 和board 创建的sequelize 模型？另外，请使用您可能已经尝试过的一些代码来更新问题以获得结果？

【解决方案1】：

你可以在 sequelize 中这样做。

//board means your model name

let result = await board.count({
    order: [sequelize.literal('id DESC')],
    limit: 10,
    where: { login_id: 1234 },
    as: 'board'
})

【讨论】：

FROM (SELECT * FROM board order by id desc limit 10) as board
request SELECT count(*) AS count FROM board AS board WHERE board.login_id = 1234;
