Question

我想定义一个函数（名为“ kayitEkle”），该函数将函数的参数插入数据库中的表（名为“ biTablo”）：

import sqlite3

connect = sqlite3.connect("obs.db")
cursor = connect.cursor()

def tabloOlustur():
    cursor.execute("CREATE TABLE IF NOT EXISTS biTablo(ad TEXT, soyad TEXT, numara TEXT, puan REAL)")
    connect.commit()


tabloOlustur()

def kayitEkle(ad, soyad, numara, puan):
    cursor.execute("INSERT INTO biTablo(ad, soyad, numara, puan) VALUES(? ? ? ?)",(ad,soyad,numara,puan))
    connect.commit()

kayitEkle('ahmet', 'yılmaz', '08067', 50)

但我收到此消息：

Traceback (most recent call last):
 File "C:/Users/pc/PycharmProjects/ikinciBahar/ogrenmeDatabase.py", line 234, in <module>
   kayitEkle('ahmet', 'yılmaz', '08067', 50)
 File "C:/Users/pc/PycharmProjects/ikinciBahar/ogrenmeDatabase.py", line 231, in kayitEkle
   cursor.execute("INSERT INTO biTablo(ad, soyad, numara, puan) VALUES(? ? ? ?)",(ad,soyad,numara,puan))
sqlite3.OperationalError: near "?": syntax error

怎么了？我该怎么办？

Answer 1

在您的cursor.execute中使用VALUES(%s, %s, %s, %s)

Answer 2

您需要正确组成字符串。假设广告，soyad，numara是字符串，而puan是数字：

cursor.execute（INSERT INTO biTablo VALUES（\“％s \”，\“％s \”，\“％s \”，％f）;“％（ad，soyad，numara，puan））< / p>

Answer 3

您可能应该使用python .format并将其行更改为

   cursor.execute("INSERT INTO biTablo(ad, soyad, numara, puan) VALUES(? ? ? ?)",(ad,soyad,numara,puan))

到

   cursor.execute("INSERT INTO biTablo(ad, soyad, numara, puan) VALUES({},{},{},{})".format(ad,soyad,numara,puan))

Answer 4

如果我没记错，这应该可以工作：

cursor.execute("INSERT INTO biTablo(ad, soyad, numara, puan) VALUES(%s, %s, %s, %s)", (ad,soyad,numara,puan))

在Python中，如何定义将函数参数插入数据库表的函数？
