Question

I have an Access DB with multiple related tables (i.e. Ta and Tb where records of Tb relate to records of Ta). I am trying to create a report where all the available data are listed in rows. However it does only depict data having records in both (Ta and Tb) I mean if I have a record in Ta which has no record related in Tb this is not depicted in the report. I wish it was instead depicted with empty or default values.

Any help is very appreciated.

As already stated by Matt in his comment, you have to join the tables via LEFT JOIN:

SELECT Ta.SomeColumn, Tb.SomeColumn
FROM Ta
LEFT JOIN Tb ON Ta.SomeColumn = Tb.SomeColumn

This shows rows in Ta that have no counterpart in Tb.
If it’s the other way round (rows in Tb that have no counterpart in Ta) you have to use RIGHT JOIN instead.
