Both Have SQL = "Structured Query Language" in their names;

As Far as I know, T-SQL (Transact SQL) is the nickname for Microsoft's version of SQL, as opposed to PL SQL(Oracle's Procedural Language/Structured Query Language) for example.

bot have different adherences to the ANSI standards for SQL, and both have numerous proprietary extensions to the language as well

SQL is the original defined language and is maintained by ISO. Transact-SQL (T-SQL) is the name that Sybase gave to their version of the language and since SQL Server is based off Sybase's old product it has the same name.

That's the precise definition. But, unless you're writing a book or something, it's pretty safe to refer to SQL or T-SQL interchangeably. I'd get more picky about it if you were comparing Oracle to SQL Server or DB2 or MySQL or some other SQL-based data management system.

SQL: a language for talking to the database. It lets you select data, mutable and create database objects (like tables, views, etc.), change database settings.

T-SQL: (procedural) extensions for SQL used by SQL Server

What makes Microsoft's SQL Extensions (TSQL) Procedural, if I might ask?

The extensions to TSQL are not necessarily procedural. For example, the CONVERT function isn't procedural. And, for sure, TSQL isn't procedural by nature. Yes, things like While loops are procedural but just because you're using TSQL doesn't mean that you're writing procedural code.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.
