dbxquery will only every show up in either the Statistics tab or the Visualizations tab because they aren't actually events in Splunk, they're tables from a DB.
You can quite easily make the results a dashboard, it just depends on what you're wanting to do. If you just want the exact results in a table from your SQL statement, you can just save that as a dashboard table. as a rough idea:
|dbxquery connection="connection1" maxrows=0 shortnames=t query="select interesting_fields from table1"
now if you want to do some SPL on top of your SQL to do some aggregations, that's fine, also.
|dbxquery connection="connection1" maxrows=0 shortnames=t query="select interesting_fields from table1"|stats sum(field1) as sum by field2
you can keep that as a table or throw it into a visualization and save it as a dashboard panel. Sky is the limit, in a sense 🙂
If you have more details, that would be helpful so we can nail down a more precise syntax. Details around what type of visualization and/or current syntax/data examples.
