Question

伪代码：

const mongoose = require('mongoose');

const { Schema } = mongoose;

const UserSchema = new Schema({
  username: String
});

mongoose.model('User', UserSchema);

const con = mongoose.connect(config.uri, config.options, (err) => {
    if(err) throw err;

    const User = con.model('User');
    User.db.db.command({ testProcedure: 1 }, console.log);
})

错误输出：

目标是在MongoDB中执行以下操作（链接转到其自己的node.js SDK）：

存储过程和UDF是本机SQL（DocumentDB）API和关联的SDK的方面。 MongoDB SDK（或专为与MongoDB配合使用的框架，例如您正在使用的Mongoose）对Cosmos DB的存储proc或UDF一无所知。

您需要使用特定语言的Cosmos DB SDK来利用这些优势。但是，我怀疑它们是否可以对使用MongoDB API设置的数据库正常工作。

Cosmos DB MongoDB API无法调用存储过程/ UDF /
