Question

在我的controller.ts

中

  @Get()
  getFuga(@Query() query: { place: string }): string {
    return query.place
  }

当我通过query投掷GET

http://localhost:3000/event?place=Tokyo

响应为Tokyo

我想通过类似的查询来获得结果

select * from events where events.place = 'Tokyo'

有什么好的方法可以实现连接DB并引发查询吗？

我是初学者，如果存在一些有用的材料，我可以伸出援手吗？

mysql> select * from events;

您可以使用Typeorm，这是使用最广泛的ORM 在nestjs中连接到各种数据库。将其集成到项目中后，可以使用Typeorm查询样式的查询生成器或活动记录，以便根据需要获取结果。

如何通过在nest.js中抛出查询来获取
