Can I create tables in my sql in sololearn?

Question

What is the best app for learning and practicing sql?

Answer 1

No, You can't.
Because there is no db here.

You can learn it here or go to SqlZoo.
For practice you can try with your local db mysql / postgre / sqlserver.

in each DBMS have unique sql function.
For light version of DBMS you can use mysql/postgre which usually used for web dev.
For more complex version you can use something like sqlserver which give alot of features like reporting.
