Okay, first off I will attempt to explain what I’m trying to do. I am trying to build a report that returns all assessments assigned to a client. Each assessment should have a corresponding event, and vice versa (unfortunately there is no token passed between the two so I have to determine the correct event based on dates). However, the event is sometimes missing, or the assessment is sometimes missing. I wish to capture all of these so that I can report where there are missing assessments or events and have them fixed. In it’s most simple form, this is what I would expect the report to look like. However, there are a few other conditions, such as returning a particular type of assessment and a particular type of event.
ID Assessment Event
1 A1 B1
2 A2
3 B3
I currently have 2 queries written that show me all assessments with their corresponding events (if present), and all events with their corresponding assessments (if present). They both seem to work well, but I would really like to join the two queries (ID would be common in both queries). I’ve tried doing this myself, but it never quite works, so I’m hoping if I post both of my working queries, someone may be able to assist!
This brings back assessments with their corresponding event (where present).

There are also some catches with a joined report – events and assessments can have different teams or workers, so I’d probably need to define seperate event team and event workers from the assessment team and event worker. I did think that this could be achieved by doing an outer join, or by joining the assessments and the events to a seperate table which returns all clients with an assessment or an event, but as mentioned, the results never seemed to quite add up to the seperate queries. I think it could be something to do with the row number = 1 condition, this is there to assist with returning a corresponding assessment to an event or vice versa, but I think when trying to join the two, this might be causing some of the problems? Anyway, thanks for your time – I will continue to tinker and see if I can find a solution, but any tips or suggestions would be much appreciated.
Why don’t you union your 2 queries? If applicable, use union all which is much performer that union.
