What is the typical structure of a CRUD service method in NestJS using Prisma?

A CRUD service method calls Prisma Client methods like create(), findMany(), update(), or delete() to perform database operations, usually wrapped in async functions.

beginner

Why should you use async/await with Prisma in NestJS?

Database operations are asynchronous. Using async/await ensures your code waits for the database response before continuing, preventing errors and making code easier to read.

Which Prisma Client method is used to add a new record to the database?

A delete()

B findMany()

C update()

D create()

The create() method adds a new record to the database.

What does the findMany() method do in Prisma?

A Finds and returns multiple records

B Updates multiple records

C Deletes multiple records

D Creates multiple records

findMany() retrieves multiple records from the database.

In NestJS, where do you usually call Prisma Client methods for CRUD operations?

A In the controller

B In the service

C In the module

D In the main.ts file

CRUD operations are typically handled in the service layer.

Which keyword is used to handle asynchronous Prisma calls in NestJS?

A await

B asyncify

C wait

D sync

The await keyword is used to wait for asynchronous Prisma calls.

What is the main benefit of using Prisma with NestJS?

A It automatically creates UI components

B It replaces the need for controllers

C It simplifies database access with type safety

D It manages server deployment

Prisma simplifies database access and provides type safety.

Explain how you would implement a 'Read' operation using Prisma in a NestJS service.
