Python SQL语句只输出列表的最后一行

下面是将数据从list appstore插入数据库ios.db中创建的Applestore表的代码

 import sqlite3
    connection = sqlite3.connect("ios.db")
    cursor = connection.cursor()
    for p in appstore[1:]: 
        format_str = """INSERT INTO Applestore (id, track_name, size_bytes, currency, price, rating_count_tot, rating_count_ver, user_rating, user_rating_ver, ver,  cont_rating, prime_genre, sup_devices_num, ipadSc_url, lang_num, vpp_lic) 
        VALUES ("{id}", "{track_name}", "{size_bytes}", "{currency}", "{price}", "{rating_count_tot}", "{rating_count_ver}", "{user_rating}", "{user_rating_ver}", "{ver}",  "{cont_rating}", "{prime_genre}", "{sup_devices_num}", "{ipadSc_url}", "{lang_num}", "{vpp_lic}");""" 
        sql_command = format_str.format(id = p[0],track_name = p[1],size_bytes = p[2],currency = p[3],price = p[4],rating_count_tot = p[5],rating_count_ver = p[6], user_rating = p[7], user_rating_ver = p[8], ver = p[9], cont_rating = p[10], prime_genre = p[11], sup_devices_num = p[12], ipadSc_url = p[13], lang_num = p[14], vpp_lic = p[15]) 

    cursor.execute(sql_command)


    connection.commit()

    connection.close()

这仅输出最后一行

import sqlite3
connection = sqlite3.connect("ios.db")
cursor = connection.cursor()
cursor.execute("""SELECT * FROM Applestore""")
print("fetchall:")
result = cursor.fetchall() 
for r in result:
    print(r)

添加上述建议后，代码如下所示：

import sqlite3
connection = sqlite3.connect("ios.db")
cursor = connection.cursor()
for p in appstore:
    format_str = """INSERT INTO Applestore (id, track_name, size_bytes, currency, price, rating_count_tot, rating_count_ver, user_rating, user_rating_ver, ver,  cont_rating, prime_genre, sup_devices_num, ipadSc_url, lang_num, vpp_lic) 
    VALUES (id, track_name, size_bytes, currency, price, rating_count_tot, rating_count_ver, user_rating, user_rating_ver, ver,  cont_rating, prime_genre, sup_devices_num, ipadSc_url, lang_num, vpp_lic);""" 
    #sql_command = format_str.format(id = p[0],track_name = p[1],size_bytes = p[2],currency = p[3],price = p[4],rating_count_tot = p[5],rating_count_ver = p[6], user_rating = p[7], user_rating_ver = p[8], ver = p[9], cont_rating = p[10], prime_genre = p[11], sup_devices_num = p[12], ipadSc_url = p[13], lang_num = p[14], vpp_lic = p[15]) 
    cursor.execute(format_str, (*p[1:16]))


connection.commit()
connetion.close()

错误：函数最多接受2个参数（给定17个）

每次在for循环中循环时都会覆盖SQL命令

您可以在for循环中放置

cursor.execute（sql\u命令）

，

---

在

sql\u命令=…

否的正下方，它打印出数据库中的所有结果；这里只有一个结果，因为appstore[1::::循环中的

p的
c.execute
不在
范围内，所以只执行最后一次插入。您不应该使用字符串格式构建SQL查询；这是一种SQL注入风险，会导致难以识别的错误queries@roganjosh同意，但这是另一个问题。7 sql\u命令=格式\u str.format（id=p[0]，track\u name=p[1]，size\u bytes=p[2]，currency=p[3]，price=p[4]，rating\u count\u tot=p[5]，rating\u count\u ver=p[6]，user\u rating=p[7]，user\u rating\u ver=p[8]，ver=p[9]，cont\u rating=p[10]，prime_genre=p[11]，sup_devices_num=p[12]，ipadSc_url=p[13]，lang_num=p[14]，vpp_lic=p[15]）--->8游标。执行（sql_命令）9 10操作错误：靠近“HOOK”：语法error@roganjosh这是我想办法完成工作的唯一方法。我还是个新手，所以就跟我说一点吧。当我把cursor.execute（sql_命令）放在for循环中时，它会给我上面的错误。如果您有其他方法，我们将非常感谢您的帮助。在过去的三天里，我一直在努力，但我感到很沮丧
