pymssql数据库操作MSSQL2005实例分析
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。

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

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.

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

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.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

Through the Go standard library database/sql package, you can connect to remote databases such as MySQL, PostgreSQL or SQLite: create a connection string containing database connection information. Use the sql.Open() function to open a database connection. Perform database operations such as SQL queries and insert operations. Use defer to close the database connection to release resources.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
