将变量从 CSV 插入 SQL 时出现编程错误

Question

我正在网络抓取数据并尝试将其放入我的 SQL 表中。即使我更改了我最初认为错误的内容，此错误仍然出现

ProgrammingError: 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 'type, bathrooms, bedrooms)VALUES('495000', '119 The Dargan Building, Heuston Sou' at line 1

最初是我的数据库表没有足够的字符来存储变量地址，它只设置为 50，但我现在将其更改为 250，但出现了同样的错误。这是现在运行的代码：

import mysql.connector
import csv
#creating csv file
with open ('daftdata.csv','w') as file:

    for row in all_var:
        writer.writerow(row)
    file.close      

mydb = mysql.connector.connect(host='localhost',
user='root',
passwd='123',
database='123')
#prepare cursor
cursor = mydb.cursor()
with open("daftdata.csv", "r") as infh:
    reader =csv.reader(infh)
#csv_data = csv.reader('daftdata.csv')
    for row in reader:
        print(row)
        cursor.execute("INSERT INTO dafttable(price, address, house type, bathrooms, bedrooms)VALUES(%s, %s, %s,%s,%s)",row)

#close the connection to the database.
mydb.commit()
cursor.close()

Answer 1

对于char 类型的列，值应该用引号括起来。查看 SQL，这应该适用于地址列，因此应该修改查询以在值周围加上单引号。

其中包含空格的列名也需要用反引号或引号括起来。这适用于house type 列。一些数据库引擎还支持用空格将列名括起来的方括号。

cursor.execute("INSERT INTO dafttable(price, address, `house type`, bathrooms, bedrooms)VALUES(%s, '%s', %s, %s, %s)",row)
