Agreed. There is always a limit when it comes to going low level. Yes it probably is an overkill to understand how a db parses an actual SQL but helpful to understand how an ORM converts to a SQL query. This is again contextual. If you are writing your own database, then may be you do want to understand the parsing. But for web dev, may be not.
- aaronem 13y ago> Yes it probably is an overkill to understand how a db parses an actual SQL Yes, I've thought that, too, but it turns out that, beyond a certain relatively low level of complexity, that's a great way to produce SQL queries which take a half hour to complete. > but helpful to understand how an ORM converts to a SQL query. Certainly, because there's a degree of complexity beyond which your ORM's going to start getting pathological and you're going to have to fall back on querying the database directly, which see point one.
