python - mysql.connector.errors.ProgrammingError : Error in SQL Syntax

Question

我正在使用 Python MySQL 连接器通过更新行来将数据添加到表中。用户输入序列号，然后添加包含序列号的行。我不断收到 SQL 语法错误，但无法弄清楚它是什么。

  query = ("UPDATE `items` SET salesInfo = %s, shippingDate = %s, warrantyExpiration = %s, item = %s, WHERE serialNum = %s")
        cursor.execute(query, (info, shipDate, warranty, name, sn, ))
        conn.commit()

错误:

mysql.connector.errors.ProgrammingError: 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE serialNum = '1B0000021A974726'' at line 1

“1B0000021A974726”是用户输入的序列号，它已经存在于表中。

Answer 1

WHERE 语句之前没有 ,
