"SQL is itself an abstraction over the "language" of query execution plans."
This is completely wrong. SQL is a declarative language, it tells database what to do, not how to do it (aka query plan).
- umanwizard 10y agoYes, hence it's an abstraction. I didn't say SQL is a way of writing query execution plans but it seems some people are interpreting my post that way.
- hackinthebochs 10y agoI'm not sure what you guys think an abstraction is, but a declarative language on top is just another kind of abstraction.
