This article is part of a series that includes SQLite, Postgresql, Firebird, Oracle RDBMS, HSQLDB, MariaDB, MongoDB, and Excel. The goal is to set up a self-standing environment for testing an ODBC extension for gawk presented here to be completed. Refer to SQLite for installing the required ODBC Driver Manager.
The test system is a debian v11 (bullseye).
As root, follow the documentation here to get and install sqlserver express for Linux. Here are the needed steps:
# wget -qO- https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add - # add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/ubuntu/20.04/mssql-server-2019.list)" # apt-get install -y mssql-server # /opt/mssql/bin/mssql-conf setup
A systemd service was set up and launched:
# systemctl status mssql-server --no-pager
● mssql-server.service - Microsoft SQL Server Database Engine
Loaded: loaded (/lib/systemd/system/mssql-server.service; enabled; vendor preset: enabled)

Get and install the ODBC drivers for sqlserver:
# apt install tdsodbc # apt install curl # curl https://packages.microsoft.com/config/ubuntu/20.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.list # apt-get update # apt-get install mssql-tools unixodbc-dev
Check that the device has been added system-wide:
# odbcinst -q -d ... [ODBC Driver 17 for SQL Server] # odbcinst -q -d -n "ODBC Driver 17 for SQL Server" [ODBC Driver 17 for SQL Server] Description=Microsoft ODBC Driver 17 for SQL Server Driver=/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.8.so.1.1
As debian, create the sampledb database using the native administration tool sqlcmd:
$ sqlcmd -S localhost -U SA -P admin2021! CREATE DATABASE sampledb go 1> SELECT Name from sys.Databases; 2> go Name ----------- master tempdb model msdb sampledb (5 rows affected)
Populate the sampledb database; statements for table creation for slqserver are available here and the ones to populate the tables here.
Click and save the files to create_tables_mssql.sql respectively populate_tables_mssql.sql.
Execute the above SQL scripts still using the default command-line administration tool, sqlcmd:
$ sqlcmd -S localhost -U SA -P admin2021! -i create_tables_mssql.sql $ sqlcmd -S localhost -U SA -P admin2021! -i populate_tables_mssql.sql
Let’s check the data:
cat - <<eot | sqlcmd -S localhost -U SA -P admin2021!
USE sampleDB
SELECT
c.country_name,
c.country_id,
l.country_id,
l.street_address,
l.city
FROM
countries c
LEFT JOIN locations l ON l.country_id = c.country_id
WHERE
c.country_id IN ('US', 'UK', 'CN');
eot
Changed database context to 'sampledb'.

Configure an ODBC DSN by editing the user’s DSN file:
$ vi ~/.odbc.ini ... [mymssqlserverdb] Driver = ODBC Driver 17 for SQL Server Server = localhost #Port = 1433 User = SA Password = admin2021! Database = sampledb Language = us_english NeedODBCTypesOnly = 1
Check the DSN:
$ odbcinst -q -s ... [mymssqlserverdb] $ odbcinst -q -s -n mymssqlserverdb [mymssqlserverdb] Driver=/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.8.so.1.1 Server=localhost Port= Database=sampledb User=SA Password=admin2021! Language=us_english NeedODBCTypesOnly=1
Try a connection to the mssql db via ODBC using the ODBC Driver Manager test tool, isql:
$ isql -v mymssqlserverdb SA admin2021!

Output:

Test the DSN with the python module pyodbc:
$ python3
import pyodbc
cnxn = pyodbc.connect(DSN='mymssqlserverdb;UID=SA;PWD=admin2021!')
cursor = cnxn.cursor()
cursor.execute("""SELECT
c.country_name,
c.country_id,
l.country_id,
l.street_address,
l.city
FROM
countries c
LEFT JOIN locations l ON l.country_id = c.country_id
WHERE
c.country_id IN ('US', 'UK', 'CN')""")
row = cursor.fetchone()
while row:
print (row)
row = cursor.fetchone()
Output:
('China', 'CN', None, None, None)
