sqlite3.IntegrityError：唯一约束失败：books.id

Question

db = sqlite3.connect("books-collection.db")
cursor = db.cursor()
# cursor.execute("CREATE TABLE books (id INTEGER PRIMARY KEY, title varchar(250) NOT NULL UNIQUE, author varchar(250) NOT NULL, rating FLOAT NOT NULL)")
cursor.execute("INSERT INTO books VALUES(1, 'Harry Potter', 'J. K. Rowling', '9.3')")
db.commit()

我收到此错误

cursor.execute("INSERT INTO books VALUES(1, 'Harry Potter', 'J. K. Rowling', '9.3')")
sqlite3.IntegrityError: UNIQUE constraint failed: books.id

如何修复这个错误??

Answer 1

如果有效，请尝试这些：

cursor.execute("INSERT OR IGNORE INTO books VALUES(1, 'Harry Potter', 'J. K. Rowling', '9.3')")

或者

cursor.execute("INSERT OR REPLACE INTO books VALUES(1, 'Harry Potter', 'J. K. Rowling', '9.3')")
