Example
To delete a row, define a model and use DeleteQueryopen in new window:
res, err := db.NewDelete().Where("id = ?", 123).Exec(ctx)
Bulk-delete
To bulk-delete books by a primary key:
books := []*Book{book1, book2} // slice of books with ids
res, err := db.NewDelete().Model(&books).WherePK().Exec(ctx)
DELETE FROM "books" WHERE id IN (1, 2)
DELETE … USING
To delete rows using another table:
res, err := db.NewDelete().
Model((*Book)(nil)).
TableExpr("archived_books AS src").
Where("book.id = src.id").
Exec(ctx)
DELETE FROM "books" AS book
USING archived_books AS src
WHERE book.id = src.id
