My saga of working with JSON documents and finding out the various errors continues. With JSON being one of the new data structures introduced inside SQL Server 2016, I have been exploring to how these are fundamentally different from using the FORXML constructs. The more I have been working and testing with this capability, the more similarities I am seeing in them. Coming from a generation of working with SQL Server for more than a decade, I try to explore and learn the new concepts keeping some reference. This helps in faster learning and can accelerate the way you work with the new concepts.

How to Attach MDF Data File Without LDF Log File – Interview Question of the Week #078
Just the other day I was busy during a performance tuning exercise I explained to the team of DBA that how much log file is critical and important for their performance. Once I was explaining the importance and role of the LDF file in the performance, one of the DBA from the team asked me question about what would they do if they somehow lose the LDF file or just have corrupted log file which they do not care now. Well, I though it was a very important question and I believe it can be a very good interview question as well. Let us learn about how to attach the MDF data file without LDF log file.

While trying to create a database on my lab server, I got below error related to System.DBNull:
