It has far better handling of a CSV/TSV file on the command line directly and is compasable in shell pipelines.

SQL is a language for data in the form of tables in relational databases.
While it can do sorting or joining or some changes, it is meant for a different domain than these tools, which other constraints, other concerns, and other patterns of use...
You don't need to load anything to a db, for starters.
You also normally don't care for involving a DB in order to use in a shell script, or for quick shell exploration.
You also can't mix SQL and regular unix userland in a pipeline (well, with enough effort you can, but it's not something people do or need to do).
Yes, I know. It's not that there isn't several ways to do it, it's that it's not really a good fit for the command line, except in the "I want to reuse SQL that I already know".
The problem isn't in having a way to use SQL to query the data from the command line, it's that SQL is long winded and with syntax not really fit in a traditional shell pipeline.
Because SQL (Structured Query Language) is the language used to access/manipulate the data, not the name for that kind of data. There have been, and are, many databases, which essentially use tabular data, which are not SQL database.
That's the first question I have after reading the title. Haven't read the article.
Edited the first sentence. Originally it was "Why it is not called SQL if works on tabular data?".
My point, if one wants cat, sort, sed, join on tabular data, SOL is exactly that. Awk is too powerful, not sure about it.
