Python實戰之MySQL資料庫操作

1. 要想使python可以操作mysql資料庫，首先需要安裝mysql-python包，在centos上可以使用一下命令來安裝

$ sudo yum install mysql-python

import mysqldb

conn = mysqldb.connect (host = "172.17.23.121", user = "fkong", passwd = "fkong", db = "fkong")
cursor = conn.cursor ()
cursor.execute ("select version()")
row = cursor.fetchone ()
print "mysql server version:", row[0]
cursor.close ()
conn.close ()

import mysqldb

conn = mysqldb.connect (host = "172.17.23.121", user = "fkong", passwd = "fkong", db = "fkong")
cursor = conn.cursor ()
cursor.execute ("""
create table test
( id int,
col1 varchar(40),
col2 varchar(40),
col3 varchar(40)
) """)
cursor.execute ("""
insert into test (id, col1, col2, col3)
values
(1, 'a', 'b', 'c'),
(2, 'aa', 'bb', 'cc'),
(3, 'aaa', 'bbb', 'ccc')
""")
conn.commit()
cursor.close ()
conn.close ()

import mysqldb

conn = mysqldb.connect (host = "172.17.23.121", user = "fkong", passwd = "fkong", db = "fkong")
cursor = conn.cursor ()
cursor.execute ("select * from test")
rows = cursor.fetchall()
for row in rows:
print "%d, %s, %s, %s" % (row[0], row[1], row[2], row[3])
print "number of rows returned: %d" % cursor.rowcount
cursor.execute ("select * from test")
while (true):
row = cursor.fetchone()
if row == none:
break
print "%d, %s, %s, %s" % (row[0], row[1], row[2], row[3])
print "number of rows returned: %d" % cursor.rowcount
cursor.close ()
conn.close ()

MySQL實戰之鎖

來自極客時間，林曉斌 丁奇 的mysql實戰45講 全域性鎖就是對整個資料庫例項加鎖。mysql 提供了乙個加全域性讀鎖的方法，命令是flush tables with read lock ftwrl 當你需要讓整個庫處於唯讀狀態的時候，可以使用這個命令，之後其他執行緒的以下語句會被阻塞 應用場景 ...
