Graphical MS-SQL Clients for a Ubuntu Desktop

I use DBeaver. There is a Debian package (.deb) available at their website. It is similar to MySQL Workbench.

To install: download the .deb file from the download page, change to the directory you put the DBWeaver deb in and run sudo dpkg -i dbeaver-*.deb.

Sqlectron is an open-source, cross-platform SQL client with a clean, simple GUI that supports Microsoft SQL Server (along with PostgreSQL, MySQL, Cassandra, and SQLite).

The simplest way to install dbeaver in Ubuntu:

sudo add-apt-repository ppa:serge-rider/dbeaver-ce
sudo apt-get update
sudo apt-get install dbeaver-ce

Run the dbeaver:

dbeaver-ce

After to install it, you can create a shortcut in desktop area using the option Create Laucher and typing the "dbeaver-ce" in command field.
