Delphi 10.2 / FireDAC / SQL Server

Recommended Posts

Having problems connecting to a SQL server. It used to work fine, but after changes by the database host, I am now having issues. I want to rule out anything I am doing. One major change is that they are now using encryption (which they should have used before). I have the OLE DB Driver for SQL server installed (the most recent version, I believe). The log is shown below:

Firstly, I highly recommend using the new MSSQLODBC Driver 17, or the SQLNCLI 11 diver over the default one.



What generation is the SQL Server?  2008? 2012? 2016? 2017? 2019?


What did you do to set up the SSL support on the client side?

This article outlines the steps needed.

Thanks for the links, Lars. I'll have a read. I do not control the server and I am only pulling a small amount of data, so I don't have a great deal of information. I'll look at what you have posted and find out what I can then post back here with either more info, or how it was solved.

Your client connection needs to set up SSL correctly to be able to connect to an SSL enabled SQL Server.

The driver installation is done on the client-side.
