For various reasons (not all of them sane), one of my clients wants to implement a data access layer using a REST API that provides a single route which takes a SQL statement as its only parameter and returns the result of that statement as an array of hashes in JSON. (For now, please ignore the problems of performance and all the other issues that arise around replacing a stateful binary protocol with a stateless textual one.) For the purposes of this question, let's assume that all queries are SELECT statements, each query is its own transaction, and the entire result is returned in one response (all responses are small-ish and cursors are implemented completely on the client-side).
Ideally, my client would like to provide SQLAlchemy as an interface for its developers and enable SQLAlchemy to use a module that would take the place of pymysql or psycopg2. Vs, say, everyone reimplementing that work using requests. So, my question: Is there an existing Python database module that either does this or does something very close to it that I can crib from? -- Thanks, Rob Kinyon
