Plain old SQL92 is not turing complete. It's just a DSL for working with structured data. Via https://stackoverflow.com/questions/900055/is-sql-or-even-tsql-turing-complete/7580013#7580013 https://stackoverflow.com/questions/900055/is-sql-or-even-ts... SQL could work here but I think GraphQL is better for client apps anyway because it's based on very easily serialized graph structures instead of a string of english words that must be parsed. The client and the server can both work with it much more easily. I think if you wanted to, you could map SQL onto GraphQL. Someone might have already done that. The opposite is also very likely already done (GraphQL mapped to SQL).
