Exploring NestJS: Querying views in a database like a pro

I am facing a minor issue, can someone guide me on how to execute a query on views within a database? My scenario is based on the following example: view here

  • The database name is bue (MySQL)
  • The view I am working with is called v1
  • I am using TYPEORM

This piece of code represents an entity:

import { ViewEntity, Connection } from 'typeorm';

@ViewEntity({
    expression: (connection: Connection) => connection.createQueryBuilder()
    .select('id')
    .from(V1, 'v1'), }) 

}
export class V1 {

}

Upon checking my error logs in the console, I found the following information: https://i.sstatic.net/jpz4Q.png

Answer №1

If you're looking to utilize View Entities, as mentioned in the latest documentation:

For example:

@ViewEntity({ 
    expression: (connection: Connection) => connection.createQueryBuilder()
        .select("post.id", "id")
        .addSelect("post.name", "name")
        .addSelect("category.name", "categoryName")
        .from(Post, "post")
        .leftJoin(Category, "category", "category.id = post.categoryId")
})
