MessageRoz, not all queries are updateable. Here are some general rules:
A query based on a single table is updateable if:
The query contains no aggregate functions or refers to a query that contains an aggregate function.
The query's Unique Values property is set to No.
The query doesn't include a GROUP BY clause.
A multi-table query with a one to one relationship is updateable provided all of the above conditions are true.
A multi-table query with a one to many relationship is updateable on both sides as long as you don't violate referential integrity rules, and provided the above conditions are true. Try adding the foreign key value to the query -- did I read where you'd tried that? If that's the case, check referential integrity -- if it's enabled, also enable the cascade updates between the two tables.
Keep in mind that the following aren't updateable, regardless: Crosstab, pass-through, and UNION (that's why I asked for the clarification about the word combine), multi-table queries based on three or more tabls in a many to one to many relationship, Totals view.
Hope something there helps.

No blank record, all fields locked.
It wouldn't surprise me if this is just a 'feature'.

Well, when you say "combine" -- I think of append or UNION. Relationships "join" records -- nothing wrong with the way you siad it -- I just thought I'd check to make sure. So here's the next question -- how do you know it's not updateable? Are you getting an error message? Is there a blank (new) record at the bottom of the query in Datasheet View?

Standard left outer join on staff ID - is there another way?!

How are you combining your tables?
Susan H.
What I'm finding (and I can't believe I never hit this before) is that although the SQL tables can be updated through the Access FE, and the local tables can be updated, combine them and wallop, not updateable. Even if all the key fields are included in the query.
