Question

我正在尝试将数据插入到我的mysql数据库中，但是我总是得到以下错误：我想添加到我的insert语句中的参数有问题，我尝试了各种解决方案，在使用“ s”，“ s”的情况下，它已插入到我的数据库中。

有人知道什么是错的吗？

谢谢。

try:
    conn = mysql.connect()
    cursor = conn.cursor()
    insert_cmd = "INSERT INTO TBTAB VALUES(%s, %s, %s, %s, %s)"
    #insert_cmd = "INSERT INTO TBTAB VALUES('s', 's', 's', 's', 's')"
    # insert_cmd = "INSERT INTO TBTAB VALUES(?, ?, ?, ?, ?)"
    tpa= ("szilva", "barack", "meggye", "alma", "korte")
    #cursor.execute("INSERT INTO TBTAB (UserName, Email, TextBoxCont, NodeChosen, CurDate) VALUES ('Caal', 'TomErichsen', 'Svanger', '400esd6', 'Nqdwasorway');")
    cursor.execute(insert_cmd.format(tpa))
    conn.commit()
    return render_template('form.html')
except Exception as e:
    return str(e)

错误：

Answer 1

You should pass the query parameters as a tuple to cursor.execute() instead of interpolating them into the query, i.e.:

cursor.execute(insert_cmd, tpa)

%s in the query serves as a placeholder for a single parameter.
