no mistake but i didnt get what i want (with python module pymssql send information to the mssql)

[gdyren at gmail.com]

the code is below:
import pymssql
conn = pymssql.connect(host = "121.198.126.233",user = "xxxx",password
= "xxxx",database = "test")
print "connecting success"
cursor = conn.cursor()
cursor.execute("insert into bbs_test values(%s,%s,%s,%s,%s)",
("1","nju","9:13","ustc","test"))
cursor.close()
conn.close()
in the idle:
connecting success

then i get into the database :test and find that there is nothing in
the table bbs_test.
i don't  know why
