A plugin to Notepad++ to parse different types of CSV files and display them in a table. The data is stored in a in-memory SQLite database (or MSSQL if configured), so you can write SQL queries against the data.
It tries to auto-detect separators, headers and column types. If it fails it asks you for it.
CsvQuery has a built-in SQLite engine. This is quite old, 3.7.7.1, so new features like windowing functions doesn't work. There is no plans on updating this (unless someone else makes a new C# port of SQLite).
However, CsvQuery can also use SQL Server as backend. Then all features in SQL Server can be used right from CsvQuery.
To use SQL Server you must first install SQL Server locally. Any version should work (there are free ones).
Make sure "Integrated security" is checked during install of SQL Server (it is by default).
Then go into CsvQuery settings (Plugins -> CsvQuery -> Settings)
- Set "StorageProvider" to "MSSQL"
- Set "Database" to "CsvQueryDB"
Now click "Read File" again, and it will use SQL Server syntax in CsvQuery.
Another option is to use an external SQLite tool with a more modern SQLite engine.
To do this, change the CsvQuery setting "Database" to a filename instead of ":memory:".
The next time you click "Read file" this file will be created as a standard SQLite file, and can be queried with the external tool.

- Support for more types of CSV files (more test cases, basically)
- Optimizations
CSV Query detects the separator by calculating the variance in occurrence of characters on each line, then chose the one that seems best, preferring one of comma, semicolon, pipe or tab. It's certainly not perfect, but it handles all the files I regularly work with, which is why I wrote the plugin in the first place.
If the first line is "significantly different" from the rest it assumes the first line is a header and use it for the column names in the database.
