問題

I am trying to connect to an Microsoft Azure SQL server database.

This is how i am trying to connect:

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"))

I am getting an error while excuting this line. The error:

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

Can't figure why this is happening, Any idea?

I also recommend you install the ODBC Driver and then try to use pyodbc. I am assuming you are on an Ubuntu 15.04+ machine.

To install the ODBC Driver follow the following instructions:

sudo su

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

sh installodbc.sh

Once you do that, install pyodbc using pip and try the following script:

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()

Let me know how that goes.

Cheers,

Meet

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

Download Dependencies depends on your platform,

(for other OS Download your Dependencies)

This example for Ubuntu:

# 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

and then change,

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

DRIVER={ODBC Driver 17 for SQL Server}
