I got some network problems and due to that SQL Nav I lost connection.
I made reconnect and I still didn’t had connection and after a while I got connection and made a new reconnect
The script editor got the << sign in the end of each line and if I used run it said “No text selected” and I needed to select the query to run.
In the DB Explorer I got only a “Node” (see screenshot)
No reconnection was able to fix that…I had to start a new session (inside the same SQLNav)
