Normally when I see a language that was created to fix problems somebody had with another language, then the two languages tend to be syntactically similar. I don't see any syntactic similarity.

Secondly I don't believe that GraphQl is meant to map to the relational algebra, which is the genesis of SQL.

GraphQL's benefit seems to be that you should be able to get all the data you need and nothing more with one query, and get it back in the form you want it. In the earlier comment that started this thread the commenter said something like that's what SQL gives you, but from my experience if you want to get back complicated data (3 joins, many properties with same names) your SQL statement is going to be a lot more difficult to write and organize than your GraphQL query. Writing the queries is generally really straightforward and it is quite quickly clear how to structure a query to get what you want, and indeed if it is even possible to structure the query. Ease of declaring what you want is a valid reason for having a new language.

Structuring a query in SQL or most query languages are generally more difficult than in GraphQL - in my experience. This of course does not mean there are not places where it can get complicated - just generally not at query construction time.

I can't really say if having a new infrastructure is a weak reason for creating a new language, I guess that depends on the infrastructure that one needs. Languages are generally really powerful tools for doing things, so if you want to do difficult things with higher productivity than previously you might feel encouraged to create a new language as part of your endeavors.

I really like your reasoning, thanks.

While I agree that GQL queries are simpler to write, it is also true that they are much less powerful.

I personally don't believe that it is a valid reason for creating a new language and all this infrastructure, but for some kind of project I can see the attractiveness.
