vCO Action used to call SQL DB

Hoping someone can help out.  I am trying to call a custom SQL query from an ASD form utilizing a vCO action.  I can make this happen through the use of a workflow, passing the SQL DB I have setup previously.  Is there a way to call that SQL DB from within the action, and perform the custom query? Any and all help would be greatly appreciated.

Custom query call below where databaseParameter = SQL DB.

var queryResult = databaseParameter.readCustomQuery(query);
