Simple, fast SQL queries for flat files

Question

Does anyone know of any tools to provide simple, fast queries of flat files using a SQL-like declarative query language? I\'d rather not pay the overhead of loading the file in

Answer 1

We'll I have a lightweight ORM for sqlite that would simplify this task without requiring any configuration files, etc.

If you can using PowerShell has a lot of powerful capabilities for parsing and querying text files (example here). Otherwise using .NET/Mono you can cut that up in and use LINQ in no time.
