javascript - Sequelize 不使用读取复制

Question

我尝试使用 sequelize 连接到读取复制:

const Sequelize = require('sequelize');
const sequelize = new Sequelize('database', null, null, {
dialect: 'mssql',
replication: {
    read: [{
        host: 'hostRead',
        username: 'username',
        password: 'password'
    }],
    write: {
        host: 'hostWrite',
        username: 'username',
        password: 'password'
    }
}
});

(async () => {
    const result = (await sequelize.query('SELECT @@servername'))[0][0];
    console.log(result);
})();

当我运行它时，它会打印写入 serverName 而不是读取的。
为什么会这样？

显然 sequelize 本身不会解析您的查询类型，因此您必须明确指定原始 sequelize 查询的查询类型，如下所示:

const result = (await sequelize.query('SELECT @@servername', { type: QueryTypes.SELECT }));
