Question

I tried to insert data to the database using python but I got a MySQLdb error

self.cur.execute('''
            INSERT INTO book(book_name, book_desc, book_code, book_category, book_author, book_publisher, book_price)
            VALUES(%s, %s, %s, %s, %s, %s, %s)
        ''', (book_title, book_desc, book_code, book_category, book_author, book_publisher, book_price, ))

self.db.commit()

I got this error:

MySQLdb._exceptions.OperationalError: (1366, "Incorrect integer value: '' for column 'book_code' at row 1")

Answer 1

According to the values you shared in the comments, book_code is a string, which is incompatible with the int value in the database. You could overcome this issue by converting it to an int :

self.cur.execute('''
            INSERT INTO book(book_name, book_desc, book_code, book_category, book_author, book_publisher, book_price)
            VALUES(%s, %s, %s, %s, %s, %s, %s)
        ''', (book_title, book_desc, int(book_code), book_category, book_author, book_publisher, book_price, ))
