如何将数据插入MySQL数据库？

Question

我想在我的MySQL数据库中插入整数188和90，但以下代码不起作用：

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()

为什么不起作用？

Answer 1

#Server Connection to MySQL:

import MySQLdb
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()

编辑 为我工作：

>>> import MySQLdb
>>> #connect to db
... db = MySQLdb.connect("localhost","root","password","testdb" )
>>> 
>>> #setup cursor
... cursor = db.cursor()
>>> 
>>> #create anooog1 table
... cursor.execute("DROP TABLE IF EXISTS anooog1")
__main__:2: Warning: Unknown table 'anooog1'
0L
>>> 
>>> sql = """CREATE TABLE anooog1 (
...          COL1 INT,  
...          COL2 INT )"""
>>> cursor.execute(sql)
0L
>>> 
>>> #insert to table
... try:
...     cursor.execute("""INSERT INTO anooog1 VALUES (%s,%s)""",(188,90))
...     db.commit()
... except:     
...     db.rollback()
... 
1L
>>> #show table
... cursor.execute("""SELECT * FROM anooog1;""")
1L
>>> print cursor.fetchall()
((188L, 90L),)
>>> 
>>> db.close()

在MySQL表;

mysql> use testdb;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> SELECT * FROM anooog1;
+------+------+
| COL1 | COL2 |
+------+------+
|  188 |   90 |
+------+------+
1 row in set (0.00 sec)
