Create Go apps using SQL Server on SLES
In this section, you will get SQL Server 2017 on your SLES machine and then you will install the necessary dependencies to run GoLang.
Step 1.1 Install SQL Server
Note: To ensure optimal performance of SQL Server, your machine should have at least 4 GB of memory.
Register the Microsoft Linux repository and add they keys.
sudo zypper addrepo -fc https://packages.microsoft.com/config/sles/12/mssql-server-2017.repo sudo zypper --gpg-auto-import-keys refresh
Install SQL Server.
sudo zypper update sudo zypper install mssql-server
Setup your SQL Server.
sudo /opt/mssql/bin/mssql-conf setup

You now have SQL Server running locally on your SLES machine! Check out the next section to continue installing prerequisites.
Step 1.2 Install GoLang
If you already have GoLang installed on your machine, skip this step. To install GoLang, follow these commands:
Run the following commands:
curl -O https://storage.googleapis.com/golang/go1.8.linux-amd64.tar.gz tar xvf go1.8.linux-amd64.tar.gz sudo chown -R root:root ./go sudo mv go /usr/local
Using your favorite text editor, add these two lines to the ~/.profile file.
export GOPATH=$HOME/work export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
Step 1.3 Install the ODBC Driver and SQL Command Line Utility for SQL Server
SQLCMD is a command line tool that enables you to connect to SQL Server and run queries.
The repository URL below is for both Suse 12 and 15.
sudo zypper ar https://packages.microsoft.com/config/sles/12/prod.repo sudo zypper update sudo ACCEPT_EULA=Y zypper install msodbcsql17 mssql-tools echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc source ~/.bashrc sudo zypper install unixODBC-devel
After installing SQLCMD, you can connect to SQL Server using the following command:
sqlcmd -S localhost -U sa -P yourpassword 1> # You're connected! Type your T-SQL statements here. Use the keyword 'GO' to execute each batch of statements.
This how to run a basic inline query. The results will be printed to the STDOUT.
sqlcmd -S localhost -U sa -P yourpassword -Q "SELECT @@VERSION"
