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

How does Go language implement the addition, deletion, modification and query operations of the database? How does Go language implement the addition, deletion, modification and query operations of the database? Mar 27, 2024 pm 09:39 PM

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

How does Hibernate implement polymorphic mapping? How does Hibernate implement polymorphic mapping? Apr 17, 2024 pm 12:09 PM

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos Jul 18, 2024 am 05:48 AM

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

How to use database callback functions in Golang? How to use database callback functions in Golang? Jun 03, 2024 pm 02:20 PM

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.
