Is your feature request related to a problem? Please describe..

It should be good enough to allow users to run multiple queries independently, for example:

Here we can see that we have 2 queries and when we try to execute the first one it fails because of a SQL syntax problem.
But if we delete the second query and execute the first one, it returns ok:

Is this a real problem or an upcoming feature? (maybe I'm stupid and you can execute more than one query)
