Preql VS partiql-lang-kotlin

Hm, I just realized there are two similar projects with very similar names: this one, and

https://github.com/erezsh/Preql

First, let me introduce myself. My name is Erez. You may know some of the Python libraries I wrote in the past: Lark, Preql and Data-diff.

Example of language that implements this: https://github.com/erezsh/Preql

But what about PreQL?

It seems people here are really interested in alternatives to SQL. So perhaps you'd also like to have a look at https://github.com/erezsh/Preql

(Same name, same goal, different approach, and already working)

There's also lark, which is used by a plethora of projects (I haven't used it, but I heard about PreQL on a podcast where they talk for a bit about what it's like to develop a new language in lark)

Just want to mention preql exists as an option - https://github.com/erezsh/Preql

I share the author's point of view, which led me to start a new relational programming language that compiles to SQL. If that sounds interesting, you can find it here: https://github.com/erezsh/Preql

Ion is heavily used on the retail side of Amazon, but it's only recently started to appear in AWS products.

AWS is starting support PartiQL (https://partiql.org/) queries in some places and PartiQL uses Ion's type system internally.

Yep, that's exactly the vision here. One of the biggest sources of precedent and inspiration for us here is https://partiql.org/ which is picking up a fair bit of traction across AWS. Also see https://rockset.com/

QLDB allows you to create a ledger that acts similar to a schema or table space in a traditional database. Once you've created this ledger, you create a table through the SQL-like query language PartiQL that also enables you to interact with the data.

PartiQL[0] is an open source library that is a superset of SQL that I really like. It supports querying nested structures inside columns, so if a column contains some JSON data you can use the standard dot notation to query nested JSON data directly

PartiQL was introduced to AWS DynamoDB, with AWS making the announcement in 2020 making the life of developers easier, with the comfort of executing commands similar to SQL.

I haven't tried it, but I'm pretty sure the problem is that timestamp (and it's various capitalizations) is a keyword in PartiQL (https://github.com/partiql/partiql-lang-kotlin/blob/master/lang/src/org/partiql/lang/syntax/LexerConstants.kt#L221). To get it to be interpreted as an attribute name, you need to enclose TimeStamp in double quotes.
