It would be nice to see adminer page the results of a SQL command query. For example I submit a query that returns 100,000 rows I could have it return 100 rows per page (for 1000 pages).
I would like SQL query to run exactly what you type. Adminer doesn't parse the query so there is no way to not transfer the data from MySQL. It is possible to hide them in PHP or JS but it would waste resources.
