SQL Server/ TypeORM -多连接。我应该如何格式化查询？

import { Entity, Column, PrimaryGeneratedColumn } from 'typeorm';

@Entity()
export class User {
  @PrimaryGeneratedColumn()
  id: number;

  @Column()
  name: string;

  @Column()
  email: string;
}

import { EntityRepository, Repository } from 'typeorm';
import { User } from './user.entity';

@EntityRepository(User)
export class UserRepository extends Repository<User> {
  // 自定义查询方法
  findByName(name: string): Promise<User[]> {
    return this.find({ name });
  }
}

import { createConnection, getConnection } from 'typeorm';
import { User } from './user.entity';
import { UserRepository } from './user.repository';

// 创建连接
createConnection()
  .then(async () => {
    // 获取连接
    const connection = getConnection();

    // 获取存储库实例
    const userRepository = connection.getCustomRepository(UserRepository);

    // 执行查询
    const users = await userRepository.findByName('John');

    console.log(users);
  })
  .catch(error => console.log(error));
