I'm seeing SSN masked on PROD and it is not masked on DEV with same exact code. I looked up the stored procedures it is calling and it is simple select statement. I inquired DB admin and he said they are not doing any masking, since they are using SQL server 2012 he is pretty sure it is not happening on sql server side(sql server 2016 and up year can do masking on DB).
I need suggestions what else I can debug or is it possible to do masking on SQL server 2012?
