I do not agree with the idea that importing generic SQL files is an appropriate way to construct DML interactions between R and an SQL engine. Sort of like responding to "what is the most effective way to beat my dog" would have implications I would not want to be associated with.

Otherwise you risk encountering Little Bobby Tables (https://www.explainxkcd.com/wiki/index.php/Little_Bobby_Tables). Since this requires custom R code anyway, I reject the whole premise of your question.
