I want to insert the integers 188 and 90 in my MySQL database, but the following code doesn't work:
我想在MySQL数据库中插入188和90这两个整数,但是下面的代码不行:
import MySQLdb
conn = MySQLdb.connect(host= "localhost",
user="root",
passwd="newpassword",
db="engy1")
x = conn.cursor()
x.execute("SELECT * FROM anooog1")
x.execute (" INSERT INTO anooog1 VALUES ('%s','%s') ", (188,90))
row = x.fetchall()
Why doesn't it work?
为什么它不工作?

#Server Connection to MySQL:

conn = MySQLdb.connect(host= "localhost",
user="root",
passwd="newpassword",
db="engy1")
x = conn.cursor()
try:
x.execute("""INSERT INTO anooog1 VALUES (%s,%s)""",(188,90))
conn.commit()
except:
conn.rollback()
conn.close()

You can turn off this feature to get a quicker startup with -A
