I already blogged about connecting to Oracle and Redshift from KDB.
Here I will cover SQL Server.
Step 0: Install Java (preferably 8) if you have not installed. java -version should give you the version
Step 1:
Follow instruction http://code.kx.com/wiki/Babel and Install Babel.
You can download Babel from wget https://github.com/CharlesSkelton/babel/raw/master/dist/babel.zip
and unzip it.
Step 2:

I assume you already have Java 8 installed. Download the corresponding SQL Server JDBC driver.
https://www.microsoft.com/en-us/download/details.aspx?id=11774
Download sqljdbc_6.0.8112.200_enu.tar.gz
Unzip and untar the file
$ gzip -d sqljdbc_6.0.7507.100_enu.tar.gz
$ tar -xf sqljdbc_6.0.7507.100_enu.tar
You can optionally create a soft link for your corresponding SQL JDBC under babel/lib. This will come in handy while starting Babel.
Note: Choose the right driver while creating the soft link: sqljdbc_6.0/enu/jre8/sqljdbc42.jar is the right one Java 8
Step 3: Start Babel
java -Xmx1024m -cp "babel.jar:sqljdbc42.jar" de.skelton.babel.Babel 6868 com.microsoft.sqlserver.jdbc.SQLServerDriver
You might have to substitute the actual path of babel.jar & sqljdbc42.jar (For Java 8)
You will see message something like this

Step 4: Start Q and connect to SQL Server
$ q
