Q:

Is Microsoft SQL Server 2016 fully ANSI SQL-92 compliant?

I am trying to find a compliance confirmation for MS SQL 2016 - if it is fully compliant with ANSI SQL-92 starndard. 
I found this article on Microsoft Docs which states it is not, but it refers to ODBC driver and Microsoft Jet engine - not sure if this is exactly the same thing, shouldn't it also relate to T-SQL?

A:

I don't believe that any version of any database platform on earth is fully compliant with any version of the standard. This is probably why you're not finding any claims of 100% compliance...
You can find some promising starting points over on Stack Overflow in the following Q & A: Database Engines and ANSI SQL Compliance
Many references linked from there are not maintained because database platforms are evolving all the time and this would be many full-time jobs to stay on top of it all. Basically:

no database platform is 100% compliant, but several come close
platforms have proprietary additions on top of the standard, so your definition of "fully compliant" may vary from someone else's
