本文实例讲述了pymssql数据库操作MSSQL2005的方法。分享给大家供大家参考。具体如下:
使用的MSSQL2005,通过pymssql来连接的。把可能用到的数据库操作方式都总结如下,如果要用的时候就备查啦。
#!/usr/bin/env python #coding=utf-8 from __future__ import with_statement from contextlib import closing import inspect import pymssql import uuid import datetime #查询操作 with closing(pymssql.connect(host='localhost',user='sa',password='pppp',database='blogs')) as conn : cur = conn.cursor() #SELECT 长连接查询操作(逐条方式获取数据) sql = "select * from pcontent" cur.execute(sql) for i in range(cur.rowcount): print cur.fetchone() #SELECT 短链接查询操作(一次查询将所有数据取出) sql = "select * from pcontent" cur.execute(sql) print cur.fetchall() #INSERT sql = "INSERT INTO pcontent(title)VAlUES(%s)" uuidstr = str(uuid.uuid1()) cur.execute(sql,(uuidstr,)) conn.commit() print cur._result #INSERT 获取IDENTITY(在插入一个值,希望获得主键的时候经常用到,很不优雅的方式) sql = "INSERT INTO pcontent(title)VAlUES(%s);SELECT @@IDENTITY" uuidstr = str(uuid.uuid1()) cur.execute(sql,(uuidstr,)) print "arraysite:",cur.arraysize print cur._result[1][2][0][0]#不知道具体的做法,目前暂时这样使用 conn.commit() #Update vl = '中国' sql = 'update pcontent set title = %s where id=1' cur.execute(sql,(vl,)) conn.commit() #参数化查询这个是为了避免SQL攻击的 sql = "select * from pcontent where id=%d" cur.execute(sql,(1,)) print cur.fetchall() # 调用存储过程SP_GetALLContent 无参数 sql = "Exec SP_GetALLContent" cur.execute(sql) print cur.fetchall() # 调用存储过程SP_GetContentByID 有参数的 sql = "Exec SP_GetContentByID %d" cur.execute(sql,(3,)) print cur.fetchall() #调用存储过程SP_AddContent 有output参数的(很不优雅的方式) sql = "DECLARE @ID INT;EXEC SP_AddContent 'ddddd',@ID OUTPUT;SELECT @ID" cur.execute(sql) print cur._result
希望本文所述对大家的Python程序设计有所帮助。

To maximize the efficiency of learning Python in a limited time, you can use Python's datetime, time, and schedule modules. 1. The datetime module is used to record and plan learning time. 2. The time module helps to set study and rest time. 3. The schedule module automatically arranges weekly learning tasks.

Python excels in gaming and GUI development. 1) Game development uses Pygame, providing drawing, audio and other functions, which are suitable for creating 2D games. 2) GUI development can choose Tkinter or PyQt. Tkinter is simple and easy to use, PyQt has rich functions and is suitable for professional development.

Python is suitable for data science, web development and automation tasks, while C is suitable for system programming, game development and embedded systems. Python is known for its simplicity and powerful ecosystem, while C is known for its high performance and underlying control capabilities.
