Dbvis query

Dbvisulaizer offers a command line functionality to execute SQL pre-configured databases (With GUI).
The remote database can be accessed from the command line without the need to authenticate.
Attention, backslash quotes and your (stacked or not) queries should end with ;
The module abuses this functionality to query the remote database and store the result.
