> Editor support of real languages is much better than SQL.
So text editors suck at supporting SQL... How is that SQL’s fault?!? Go complain to the text editor authors.
> Package managers enable code re-use.
Yup. Build one for SQL, then you can re-use SQL code. Just like someone had to build one for every other language. What does this prove about SQL being inferior to other languages? A: Nothing at all.
My point is that I think it is inferior for general application/business logic programs. For queries that filter large datasets to small result sets, SQL is probably better as it has the built in indexes and query planner (plus ACID).
I am pointing out that the current environment (better text editors and package managers) favours general languages, so they are a better current choice (to use in combination with SQL) over just writing everything, including application logic, in SQL.
