An interpreted relational query language that compiles to SQL
Project description
Preql (pronounced: Prequel) is an interpreted relational query language.
It is designed for use by data engineers, analyists and data scientists.
-
Preql compiles to SQL at runtime. It has the performance and abilities of SQL, and much more.
-
Programmer-friendly syntax and semantics, with gradual type-checking, inspired by Typescript and Python
-
Interface through Python, HTTP or a terminal environment with autocompletion
-
Escape hatch to SQL, for all those databse-specific features we didn't think to include
-
Support for Postgres, MySQL and Sqlite. (more planned!)
(Preql is currently at the alpha stage, and isn't ready for production use yet)
Get started
Simply install via pip:
pip install -U preql
Then just run the interpeter:
