Join Properties - Show all records

G

Guest

I've got a query that is linking 2 tables. However, I'm having problems with
the join properties in linking these tables.



Basically from what I can understand, there are 3 options:

1. Where join field from both tables are equal

2. All records from table 1 and only those from table 2 where they match

3. All records from table 2 and only those from table 1 where they match



How do I go about having all records from both tables showing?



The tables are as follows:

Table 1

Field 1: Department

Field 2: Actual Numbers

Field 3: Actual Income



Table 2:

Field 1: Department

Field 2: Budget Numbers

Field 3: Budget Income



Both tables come from different data sources, otherwise I would just have
one table

There are some Departments (Field 1) in table 1 that aren't in table 2 and
vice versa.

Basically I want my report to have the following columns:



Department---Actual Numbers---Budget Numbers---Actual Income---Budget Income.



For all Departments (Field 1) from both tables.

Any ideas would be very much appreciated

You can use a union query

SELECT A.*, B.* FROM TABLE1 A INNER JOIN TABLE2 B ON (A.FIELD1 = B.FIELD2)
UNION ALL
SELECT A.*, B.* FROM TABLE1 A LEFT JOIN TABLE2 B ON (A.FIELD1 = B.FIELD2)
WHERE B.FIELD2 IS NULL
UNION ALL
SELECT A.*, B.* FROM TABLE1 A RIGHT JOIN TABLE2 B ON (A.FIELD1 = B.FIELD2)
WHERE A.FIELD1 IS NULL

The Jet database engine doesn't support full outer joins, so you have to
combine a left join with a right join via a union query. The result will
not be updatable, but if you just want it for a report that should be fine.
Try something like this:

SELECT
[Table 1].Department,
[Actual Numbers],
[Budget Numbers],
[Actual Income],
[Budget Income]
FROM [Table 1] LEFT JOIN [Table 2]
ON [Table 1.Department] = [Table 2.Department]
UNION ALL
SELECT
[Table 2].Department,
[Actual Numbers],
[Budget Numbers],
[Actual Income],
[Budget Income]
FROM [Table 1] RIGHT JOIN [Table 2]
ON [Table 1.Department] = [Table 2.Department]
WHERE [Table 1].Department Is Null

Thanks Dirk,

This has got me the furthest so far. However, i'm getting duplicate values
in the budget. i think i may need to put a max expression against the budget
figures.

is it just a case of putting

Max[Budget Numbers],

Thanks in advance
