我的程序在执行要插入数据库的函数后发送以下错误消息:

Traceback:
`Traceback (most recent call last):
  File "C:\Python33\Archive\MySQL-teste12.py", line 275, in <module>
    inserir(cursor, cx2)
  File "C:\Python33\Archive\MySQL-teste12.py", line 193, in inserir
    cursor.execute(add_produto)
  File "C:\Python33\lib\site-packages\mysql\connector\cursor.py", line 415, in execute
    self._handle_result(self._connection.cmd_query(stmt))
  File "C:\Python33\lib\site-packages\mysql\connector\connection.py", line 593, in cmd_query
    result = self._handle_result(self._send_cmd(ServerCmd.QUERY, query))

    raise errors.get_exception(packet)
mysql.connector.errors.ProgrammingError: 1054 (42S22): Unknown column 'd' in 'field list'`

正在尝试插入下表:

produto = """
     CREATE TABLE produto (
     prod_nu int(11) NOT NULL AUTO_INCREMENT,
     nome varchar(30) NOT NULL,
     data_lcm date NOT NULL,
     preco int(11) NOT NULL,
     PRIMARY KEY (prod_nu)
     ) ENGINE=InnoDB
     """

以下是发生错误的过程。我相信它不接受任何格式的约会。我尝试了很多变化,但没有一个变化:

def inserir (cursor, db):
    # excess code removed                
    vb = input('Digite a data de Lançamento do Produto (Ano/mês/dia).')
    now = time.strftime('vb')
    …
    add_produto = ("""INSERT INTO produto(nome,
                      data_lcm, preco)
                      VALUES (%s, %s, %s)""" % (va,vb,vc))

    cursor.execute(add_produto)
            …

1 个答案:

答案 0 :(得分:1)

有两个问题,第一个问题是你永远不会创建一个date对象。根据你的指示(Ano /mês/ dia),这就像是

input_date = datetime.strptime(input_string, '%Y/%m/%d')

第二个问题是

now = time.strftime('vb')

now设置为'vb',因为它没有strftime指令。如果您正在寻找标准时间格式,date.isoformat()很难出错

now = input_date.isoformat()
