python含中文字符串插入mysql失败

在执行这段语句是出现了下面的错误，弄了一晚上没解决，哪位大神帮忙看下

con=MySQLdb.connect(host="127.0.0.1",port=3306,user="root",passwd="root",db="mysql")
cur=con.cursor()
for line in new_insert:
    rank,forum,title,author,follow,title_time=line
    print chardet.detect(rank)
    print chardet.detect(forum)
    print chardet.detect(title)
    print chardet.detect(author)
    print chardet.detect(follow)
    print chardet.detect(title_time)

    forum=forum.decode('ascii').encode('utf-8')
    author=author.decode('ascii').encode('utf-8')
    follow=follow.decode('ascii').encode('utf-8')
    title_time=title_time.decode('ascii').encode('utf-8')
    cur.execute("SET NAMES utf8")
    sql="INSERT INTO bbs VALUES(%s,%s,%s,%s,%s,%s)"%(rank,forum,title,author,follow,title_time)
    result=cur.execute(sql)
    if result!=1:
        print rank,forum,title,author,forum,"insert error"
        con.rollback()
        continue
    con.commit()
cur.close()
con.close()

请查看你数据库编码是否是utf-8,如果不是的话，需要设置下。

---

把这句SQL组装出来，一般能找到问题。还有其他可能是：
1，数据库编码忘记设置字符集，建表不加字符集默认就是拉丁。插入中文会报错。
2，SQL语句个别字段有单双引号或者有转义符。

---

需要设置数据库的默认编码，比如

 CREATE DATABASE `mydb` CHARACTER SET utf8 COLLATE utf8_general_ci;

---

你把你执行的sql打印出来，放在mysql数据库执行，看能否成功，先看一下是不是你sql语法的问题。
