python & mysql，执行操作失败； 无法处理参数

Question

I have this code:

my_cursor = my_db.cursor()

def Insert_object(Title, Details, Amount):
    sql_command = 'INSERT INTO income (title, details, amount) VALUES (%s, %s, %d)'
    values = (Title, Details, Amount)
    my_cursor.executemany(sql_command, values)
    my_db.commit()


Insert_object('Chips', 'Chili', 12)

but it throws the following error:

mysql.connector.errors.InterfaceError: Failed executing the operation; Could not process parameters

Answer 1

In MySQL documentation it says that the second argument of executemany function is a list of tuples. Try changing values so that it is a list that contains a single tuple.

values = [(Title, Details, Amount)]
my_cursor.executemany(sql_command, values)
