    <p>Have you considered outputing the query as XML? I am not sure what RDBMS you are using, but a SQL-Server example would be:</p> <pre><code>CREATE TABLE #IncidentReport(id INT, startTime DATETIME, endTime DATETIME, leadAgent VARCHAR(20)) CREATE TABLE #IRCameras(incidentId INT, camId INT, camName VARCHAR(50), camLocation VARCHAR(50)) CREATE TABLE #IRNotes(incidentId INT, operatorName VARCHAR(50), operatorId INT, noteText VARCHAR(50)) CREATE TABLE #IRGroupsAssigned(incidentId INT, groupId INT, groupName VARCHAR(50)) CREATE TABLE #IRWidgetsUsed(incidentId INT, widgetId INT, widgetName VARCHAR(50), widgetUse VARCHAR(50)) INSERT #IncidentReport VALUES (1, GETDATE()-2, GETDATE()-1, 'Joe'), (2, GETDATE(), GETDATE()+1, 'Karen') INSERT #IRCameras VALUES (1, 1, 'Camera1', 'Office #123'), (1, 2, 'Camera2', 'Outer Space'), (2, 345, 'Camera3', 'Office #2323'), (2, 12, 'Jane''s Cam', 'Inner Space') INSERT #IRNotes VALUES (1, 'Sam', 1234, 'I said Hello to the Customer'), (1, 'Joe', 322, 'Good Job'), (2, 'Jeff', 32323, 'How is the case going') INSERT #IRGroupsAssigned VALUES (1, 222, 'Red Team'), (1, 223, 'Blue Team'), (1, 224, 'Yellow Team'), (2, 222, 'Red Team') INSERT #IRWidgetsUsed VALUES (1, 123, 'A widget', 'Tightened'), (1, 122, 'Another widget', 'Loosened'), (2, 223, 'Super widget', 'Unknown') SELECT ID, StartTime, EndTime, LeadAgent, ( SELECT CamID, CamName, CamLocation FROM #IRCameras c WHERE ir.ID = c.IncidentID FOR XML PATH('Cameras'), TYPE ), ( SELECT OperatorName, OperatorID, NoteText FROM #IRNotes n WHERE ir.ID = n.IncidentID FOR XML PATH('Notes'), TYPE ), ( SELECT GroupID, GroupName FROM #IRGroupsAssigned g WHERE ir.ID = g.IncidentID FOR XML PATH('GroupsAssigned'), TYPE ), ( SELECT WidgetID, WidgetName, WidgetUse FROM #IRWidgetsUsed w WHERE ir.ID = w.IncidentID FOR XML PATH('WidgetsUsed'), TYPE ) FROM #IncidentReport IR FOR XML PATH ('IncidentReport'), ROOT DROP TABLE #IncidentReport DROP TABLE #IRCameras DROP TABLE #IRNotes DROP TABLE #IRGroupsAssigned DROP TABLE #IRWidgetsUsed </code></pre> <p>Not sure if you can apply any of this logic to your situation but it has been 7 hours and nobody has posted any other ideas so thought I would throw this out there.</p>

    1. COThat is an interesting solution. I have to support SQLServer and Postgres in my app so I am hoping for something that is standard SQL rather than an extension. There is some XML support in postgres but the performance doesnt seem to be very good.

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
