刚开始学python时，大家都习惯用pymssql去读写SQLSERVER。但是实际使用过程中，pymssql的读写性能以及可靠性的确不如pyodbc来的好。
正如微软官方推荐使用pyodbc库，作为学习以及生产环境使用。参考链接 https://docs.microsoft.com/en-us/sql/connect/python/python-driver-for-sql-server?view=sql-server-2017
第一步、为pyodbc Python开发配置开发环境。
1、在Windows上安装Microsoft ODBC SQL Server驱动程序
window根据需要 安装
Download Microsoft ODBC Driver 17 for SQL Server (x64) Download Microsoft ODBC Driver 17 for SQL Server (x86)
linux以centos为例
sudo su #Download appropriate package for the OS version #Choose only ONE of the following, corresponding to your OS version #RedHat Enterprise Server 6 curl https://packages.microsoft.com/config/rhel/6/prod.repo > /etc/yum.repos.d/mssql-release.repo #RedHat Enterprise Server 7 curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/mssql-release.repo #RedHat Enterprise Server 8 and Oracle Linux 8 curl https://packages.microsoft.com/config/rhel/8/prod.repo > /etc/yum.repos.d/mssql-release.repo exit sudo yum remove unixODBC-utf16 unixODBC-utf16-devel #to avoid conflicts sudo ACCEPT_EULA=Y yum install msodbcsql17 # optional: for bcp and sqlcmd sudo ACCEPT_EULA=Y yum install mssql-tools echo ‘export PATH="$PATH:/opt/mssql-tools/bin"‘ >> ~/.bash_profile echo ‘export PATH="$PATH:/opt/mssql-tools/bin"‘ >> ~/.bashrc source ~/.bashrc # optional: for unixODBC development headers sudo yum install unixODBC-devel
完成odbc驱动的安装后，依赖环境就已经完成了
2、安装pyodbc
这个只要pip安装下就好了。
pip install pyodbc
3、如何使用pyodbc进行t-sql操作
1）简单查询
import pyodbc # Some other example server values are # server = ‘localhost\sqlexpress‘ # 实列名称 # server = ‘myserver,port‘ # 如果实例是有特殊端口号的，默认1433 server = ‘tcp:myserver.database.windows.net‘ database = ‘mydb‘ username = ‘myusername‘ password = ‘mypassword‘ cnxn = pyodbc.connect(‘DRIVER={ODBC Driver 17 for SQL Server};SERVER=‘+server+‘;DATABASE=‘+database+‘;UID=‘+username+‘;PWD=‘+ password) cursor = cnxn.cursor() cursor.execute("SELECT @@version;") row = cursor.fetchone() while row: print(row[0]) row = cursor.fetchone()
2）执行操作
cursor.execute(""" INSERT INTO SalesLT.Product (Name, ProductNumber, StandardCost, ListPrice, SellStartDate) VALUES (?,?,?,?,?)""", ‘SQL Server Express New 20‘, ‘SQLEXPRESS New 20‘, 0, 0, CURRENT_TIMESTAMP) cnxn.commit() row = cursor.fetchone() while row: print(‘Inserted Product key is ‘ + str(row[0])) row = cursor.fetchone()
3）如何使用window验证
cnxn = pyodbc.connect(‘DRIVER={ODBC Driver 17 for SQL Server};SERVER=‘+server+‘;DATABASE=‘+database+‘;Trusted_Connection=yes)
