Why are there no quizzes for SQL in Sololearn ?

Answer 1

Hi M Trawally
Let me disagree with Coder's Crux
I think that is just because no one has put an effort in developing the quizzes, as nowadays Data Base (db) creation and management (with SQL) has become a kind of secondary task, specially among developers, and there is always some kind of framework to facilitate the task.
However, proper DB modelling, creation and management is a important task.
One difficulty in creating quizzes for SQL is that they would be kind of lengthy, as good quizzes would involve questions related to manipulate data in DB ER tables.
Otherwise, it would be boring question like: What the command SELECT do? Or something alike.

Answer 2

I am guessins because there isn't really much of a challenge with sql. It isn't really a language that uses objects, it's just a set of rules in order to use it.
