Level of knowledge of T-SQL?

Question

Transact SQL

They ask questions at interviews - at what level do you know T-SQL?
Well, I'm writing queries to the database .. what level is it? And what are they generally?

Answer 1

Database queries can be written in different ways. You can write data manipulation programs in T-SQL - in one program there can be a bunch of nested queries and work with cursors - the "data processing" level. Also T-SQL is able to work with events in tables - through triggers - the "automation" level.
So I divided my knowledge of T-SQL into 3 levels - 1. queries, 2. processing, 3. automation
