Python + MySQL 效能增進

下面是一篇Python使用SSCursor做MySQL資料查詢的文章 其中使用SSCursor做大量資料查詢時,可以更有效能 有興趣的人,可以參考一下: http://fcamel-life.blogspot.com/2010/08/python-mysql.html 下面是可用的Code,可以參考: import MySQLdb from MySQLdb.cursors import SSCursor db = MySQLdb.connect(host="db_ip_address", user="db_user", passwd="db_password", db="db_name") sql = "SELECT * FROM some_table" cursor = db.cursor(cursorclass=SSCursor) #cursor = db.cursor() cursor.execute(sql) result = cursor.fetchall() try:   for record in result:     print record[0] finally:   cursor.close()   db.close()
