Is there a language that does both what SQL does and general purpose programming?

I want to implement some game logic with a lot of relations between objects similar to those of relational databases or graph databases.

I know no language that would both allow me to do :

• Strong, safe relationnal mapping with non nullable links, cascade deletion, ect.
• Implement game logic
• Write pure functions
• Networking
• If possible, a decent data access performance. (Like in-memory SQLlite is acceptable)

I want to avoid using 2 languages and map the data between both using some quite complex ORM. Instead I would like a language that is capable of all of these.

Obsiouly, there is SQL. But I do not know any implementation of SQL that :

• Is capable of networking other than replying to SQL requests
• Have the many features of a language like F# ? SQL is capable of functional programming but what about F# features like pipes, partial applications, pattern matching, strong typing over primitive types ?

I will accept partial alternative solutions.

Note that I do not need actual persistance storage, only objects relation like relationnal databases, or even graph databases do.
