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.

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':
