Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01There seems to be no way without a pipe, you seem to need to reparse the columns, e.g. the tutorial at: csvkit.readthedocs.io/en/latest/tutorial/2_examining_the_data.html#csvgrep-find-the-data-you-need does:
csvcut -c county,item_name,total_cost data.csv | csvgrep -c county -m LANCASTERThis is a weak point of grep, it can't handle large lines that don't fit fully into memory:

From Machine Learning to Autonomous Intelligence by Yann LeCun (2023)
Source. After a bunch of B.S., LeCun goes on to describe his AGI architecture. Nothing ground breaking, but not bad either.Minimal example: nodejs/sequelize/raw/recursive.js
More advanced SQL tree traversal examples: nodejs/sequelize/raw/tree.js
Often known simply as SQL Server, a terrible thing that makes it impossible to find portable SQL answers on Google! You just have to Google by specific SQL implementation unfortunately to find anything about the open source ones.
