Use windows authentication out of the domain

You don't need to have your computer on the domain to use Windows Authentication.

Just use the runas command (tested on Windows 10 Home)

This is my SQL Server Management Studio shortcut:

"C:\Program Files (x86)\Microsoft SQL Server\140\Tools\Binn\ManagementStudio\Ssms.exe"



 Create a copy of the shortcut and change the target, adding the following to the beginning:

%windir%\System32\runas.exe /netonly /user:domain\username


 The full target in my shortcut looks like this:

%windir%\System32\runas.exe /netonly /user:domain\username "C:\Program Files (x86)\Microsoft SQL Server\140\Tools\Binn\ManagementStudio\Ssms.exe"


Notice that I also changed the Shortcut Name to Windows Authentication and the icon as well
 

When I double click the new shortcut, I'm asked for my domain user password


And once I'm authenticated, I can open a database using Windows Authentication.

NodeJS MSSQL connection error "EINVALIDSTATE"

It took me some time to find the reasons for the connection error below: Requests can only be made in the LoggedIn state, n…", code: "EINVALIDSTATE" I was trying to connect to MS Sql server using Node JS TEDIOUS package. The code from the Microsoft  is very simple and didn't return a more complete error message. This is the original code: ... var connection = new Connection(config);  connection.on( 'connect' , function ( err ) {  // If no error, then good to proceed.  console .log( "Connected" );  executeStatement(); }); ... Checking the internet a bit more, I found a way to get more insight into the error: ... var  connection =  new  Connection(config);  connection.on( 'connect' ,  function ( err )  {  if (err) return console.error(err);   console .log( "Connected" );  executeStatement(); }); ... That raised: ConnectionError {message: "Failed to connect to 10.0.0.100:1433 - c...

AWS Athena and S3 Partitioning

Athena is a great tool to query your data stored in S3 buckets. To have the best performance and properly organize the files I wanted to use partitioning. Although very common practice, I haven't found a nice and simple tutorial that would explain in detail how to properly store and configure the files in S3 so that I could take full advantage of the Athena partitioning features. After some testing, I managed to figure out how to set it up. This is what I did: Starting from a CSV file with a datetime column, I wanted to create an Athena table, partitioned by date. A basic google search led me to this  page , but It was lacking some more detailing. The biggest catch was to understand how the partitioning works. Based on a datetime column(processeddate), I had to split the date into the year, month and day components to create new derived columns, which in turn I'll use as the partition keys to my table Example of d...

SQL Server connection using windows authentication from a different domain

I had to connect to a SQL Server database from my laptop that is not on the same domain as the DB server. I'm using JTDS to connect to the DB, in this case using Talend. On the first few attempts I received this error: The login is from an untrusted domain and cannot be used with Windows authentication After playing with many different parameter combinations,  I finally managed to have a successful connection using the following connection string: jdbc:jtds:sqlserver://<SERVERIP>:<PORT>/<DATABASE>;instance=<INSTANCE>;useNTLMv2=true;domain=<DOMAIN>;user=<LOGIN>;password=<PASSWORD> This is the screenshot of the connection configuration on Talend: And the output of the 'Test connection':
