Linux python3 - 无法打开lib'SQL Server'

Question

我正在尝试连接到Microsoft Azure SQL Server数据库.

这是我试图连接的方式:

 conn = pyodbc.connect('DRIVER={SQL Server};SERVER=%s' % (self.config.get("Sql", "DataSource")),
                        user= self.config.get("Sql", "UserId"),
                        password=self.config.get("Sql", "Password"),
                        database=self.config.get("Sql", "Catalog"))

我在排除这一行时遇到错误.错误:

pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'SQL Server' : file not found (0) (SQLDriverConnect)")

想不通为什么会这样,有什么想法吗？

Answer 1

我还建议您安装ODBC驱动程序,然后尝试使用pyodbc.我假设你使用的是Ubuntu 15.04+机器.

要安装ODBC驱动程序,请遵循以下说明:

sudo su
wget https://gallery.technet.microsoft.com/ODBC-Driver-13-for-Ubuntu-b87369f0/file/154097/2/installodbc.sh
sh installodbc.sh

完成后,使用pip安装pyodbc并尝试以下脚本:

import pyodbc
server = 'tcp:myserver.database.windows.net'
database = 'mydb'
username = 'myusername'
password = 'mypassword'
cnxn = pyodbc.connect('DRIVER={ODBC Driver 13 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
    row = cursor.fetchone()

让我知道这是怎么回事.

干杯,
见面

Answer 2

替换DRIVER={SQL Server}为DRIVER={/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.0.so.1.1}

Answer 3

下载依赖项取决于您的平台，（对于其他操作系统下载您的依赖项）

这个 Ubuntu 示例：

# sudo su 
curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -

#Download appropriate package for the OS version
#Choose only ONE of the following, corresponding to your OS version

#Ubuntu 14.04
# curl https://packages.microsoft.com/config/ubuntu/14.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

#Ubuntu 16.04
curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

# #Ubuntu 18.04
# curl https://packages.microsoft.com/config/ubuntu/18.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

# #Ubuntu 18.10
# curl https://packages.microsoft.com/config/ubuntu/18.10/prod.list > /etc/apt/sources.list.d/mssql-release.list

# #Ubuntu 19.04
# curl https://packages.microsoft.com/config/ubuntu/19.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

exit
sudo apt-get update
sudo ACCEPT_EULA=Y apt-get install msodbcsql17
# optional: for bcp and sqlcmd
sudo ACCEPT_EULA=Y apt-get 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 apt-get install unixodbc-dev

然后改变，

DRIVER={/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.0.so.1.1} 

DRIVER={ODBC Driver 17 for SQL Server}
