MS Access Query Query
February 20, 2012 8:46 AM   Subscribe

Complicated (or probably not complicated) MS Access question that I'm not sure how to google for.

So I have a table called Sequences which contains SeqNum (primary key), ID (a train service ID) and Node (a place the train goes through).

I have another table called Area Boundaries which has a smaller subset of nodes and an associated area.

I want to do a query which shows all the records from Sequences and then adds on the end if there is an associated area. Roughly 1 node in 30 has an associated area. If there isn't an associated area I just want a blank entry.

Right now I am getting a result which shows only the nodes with the asociated area and not the whole thing. I've tried messing about with "Is Null", "Is Not Null" and " " " ", but to no avail.

What you want is to play with the join properties (you can right click on the join in your query) to include ALL from Sequences. If you google join properties access you can find examples for your version.

Thanks! Such a simple solution. That has been annoying me for HOURS!

Problem is well and truly 100% perfectly solved.

SELECT Sequences.*, Areas.Area
FROM Sequences INNER JOIN Areas ON Sequences.Node = Areas.Node;

desjardins: he needs a left join, not an inner join

OP: for the love of God, rename "ID" to "TrainServiceID" everywhere

Thanks, thelonius, I have actually done that in most places, but your point is well made.
I'll go and make sure that's the case.
