Writing Data
Delete Queries

Delete Queries

The examples use the following Prisma schema:

model Post {
    id        String   @id @default(cuid())
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
    published Boolean
    title     String
    content   String?
 
    comments Comment[]
}
 
model Comment {
    id        String   @id @default(cuid())
    createdAt DateTime @default(now())
    content   String
 
    post   Post   @relation(fields: [postID], references: [id])
    postID String
}

Delete

delete will delete the record referenced by a single unique filter and return it.

The following example finds a single post and deletes it, returning the deleted post.

use prisma::post;
 
let deleted_post: post::Data = client
    .post()
    .delete(post::id::equals("id".to_string()))
    .exec()
    .await?;

Delete Many

delete_many will delete the records referenced by a Vec of any filters and return the number of deleted records.

The following example finds a group of comments and deletes them, returning the number of deleted comments.

use prisma::comment;
 
let deleted_comments_count: i64 = client
    .comment()
    .delete_many(vec![
        comment::content::contains("some text".to_string())
    ])
    .exec()
    .await;
