我有一个MySQL数据库和一个包含模式的表
tweet_id BIGINT
tweet_metadata LONGBLOB
我试图在我的数据库中插入一行，如下所示：
import MySQLdb as mysql
host = 'localhost'
user = 'root'
passwd = '************'
db = 'twitter'
insert_tweet_query = ''' INSERT INTO tweets(tweet_id, tweet_metadata) VALUES(%s, %s)'''
''' Creates a MySQL connection and returns the cursor '''
def create_connection():
connection = mysql.connect(host, user, passwd, db,use_unicode=True)
connection.set_character_set('utf8')
cursor = connection.cursor()
cursor.execute('SET NAMES utf8;')
cursor.execute('SET CHARACTER SET utf8;')
cursor.execute('SET character_set_connection=utf8;')
return connection, cursor
''' Close the connection '''
def close_connection(cursor, connection):
cursor.close()
connection.commit()
connection.close()
connection, cursor = create_connection()
tweet = dict({u'contributors': None, u'truncated': False, u'text': u'RT @HMV_Anime: \u7530\u6751\u3086\u304b\u308a\u59eb\u30d9\u30b9\u30c8\u30a2\u30eb\u30d0\u30e0\u300cEverlasting

cursor.execute(insert_tweet_query, (tweet['id_str'], tweet))
close_connection(cursor, connection)
然而，尽管设置了适当的'UTF-8'编码，我得到如下例外
_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 \': \'NULL\', u\'truncated\': \'0\', u\'text\': "\'RT @HMV_Anime: \\xe7\\x94\\xb0\\xe6\\x9d\\x91\\\' at line 1')
我做错了什么？
答案 0 :(得分：1)
您可以尝试 repr ：
cursor.execute(insert_tweet_query, (tweet['id_str'], repr(tweet)))
