Question

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

这就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)")

无法理解为什么会发生这种情况，不知道吗？

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，请按照以下说明操作：

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

一旦你这样做，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。

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

下载依赖项取决于您的平台，（对于其他操作系统Download your Dependencies）

此示例适用于Ubuntu：

1objij(i=0,j=0) = 0
1objij(i=0,j=1) = 1

然后更改

# 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
