python MySQLdb在尝试插入到表中时得到无效语法

我一直在犯这个错误

知道为什么吗

提前谢谢你的帮助

更新#2，我删除了“类别名称”上的双单引号，但现在甚至

  File "testdb.py", line 51
    """, (''gas-stations'', business_nameg, business_address1g, business_cityg, business_stateg, business_zipcodeg, phone_number1g, website1g, website2g))
              ^
SyntaxError: invalid syntax

还是有这个错误

import MySQLdb  

conn =  MySQLdb.connect(host="localhost",port=22008,user="cholestoff",passwd="whoami",db="mydatabase")  
cursor = conn.cursor()  

## Find mysql version  
cursor.execute ("SELECT VERSION()")  
row = cursor.fetchone()  
print "server version:", row[0]  

website1g = "http://www.triman.com"  
business_nameg = "Triman Sales Inc"  
business_address1g = "510 E Airline Way"  
business_cityg = "Gardena"  
business_stateg = "CA"  
business_zipcodeg = "90248"  
phone_number1g = "(310) 323-5410"  
phone_number2g = ""

    INSERT INTO yellowpages(categories_name, business_name)

再次感谢您的帮助

我想您的问题在于：

server version: 5.1.33-community  
Traceback (most recent call last):  
  File "testdb.py", line 23, in <module>  
    """, ('gas-stations', business_nameg))  
  File "C:\Python26\lib\site-packages\MySQLdb\cursors.py", line 173, in execute  
    self.errorhandler(self, exc, value)  
  File "C:\Python26\lib\site-packages\MySQLdb\connections.py", line 36, in   defaulterrorhandler  
    raise errorclass, errorvalue  
_mysql_exceptions.ProgrammingError: (1064, "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 'gas-stations'',''Triman Sales Inc'')' at line 2")

这会导致语法错误。您可能希望使用一组引号：

''gas-stations''

如果要将值

“gas-stations”

插入包含引号的数据库，则可以转义引号或用双引号而不是单引号将字符串括起来：

'gas-stations'

---

“向上箭头”指向错误位置的原因是因为您的线条太长，以至于缠绕在控制台上。请缩短线条，或拓宽控制台窗口以查看错误的真正位置。

您不能使用双单引号（即

“加油站”

）-只使用单引号（

'gas-stations'

）或实际的双引号（

'gas-stations'

）。

对于第二个问题，您需要丢失VALUES子句中的所有单引号字符…看起来应该像

值（%s，%s）

而不是

值（'%s'，'%s'）

一般规则非常简单：对于每个参数，都有一个位置标记（对于mySQLdb，这是

%s

）在SQL语句中，在参数元组中提供一个Python表达式。然后向后倾斜，让接口软件为您做正确的事情。这包括正确引用字符串。不要自己尝试这样做。特别是，字符串表达式应该正是您希望稍后检索的内容

示例：加油站的

business\u name

是作为Python字符串常量的“O'Reilly's Pump'n'Go”。这将在构造的SQL中作为

…值（…，'O'Reilly's Pump'n'Go'，…

结束，而您不必考虑它。

我也遇到了这样的错误，我通过将值下的“%s”替换为%s来解决它

"'gas-stations'"

    VALUES(%s,%s)
