Find All Differences Between 2 Tables

I have this 2 tables:

Table1: Table2:

ID Value ID Value
--------- ---------
1 2 2 1
2 1 3 4
4 3 4 4I

need to find all differences between the 2 Tables.

A mismatch can be:

- Table1.ID exists, Table2.ID does not exist
- Table2.ID exists, Table1.ID does not exist
- Table1.ID = Table2.ID and Table1.Value <> Table2.Value

So I want to be returned:

ID Value ID Value
--------------------
1 2 NULL NULL
4 3 4 4
NULL NULL 3 4

There must be something simpler than the solution I came up with which is:select * from Table1 a full outer join Table2 b on a.Id = b.Id

WHERE a.value <> b.value or (a.value IS NULL and b.value IS NOT NULL) or (a.value IS NOT NULL and b.value IS NULL)Martin
