query displaying 2 tables without losing any records

I want to combine two tables into one query, displaying all the records from both tables.
All I get is a query displaying double records or a query filling the wrong fields.
Who can help me?
Please try to answer my question as simple as possible because I’m Dutch.....

You can use this Union Query:

SELECT Table1.SponsorID, Table1.Amount, '' as Material
FROM Table1

UNION

SELECT Table2.SponsorID, 0 as Amount, Table2.Material
FROM Table2

ORDER BY SponsorID;

How are the tables related??

km3Author Commented:
The tables are relates by "zoeknaam" ("searchname")
One table is a table with sponsors sponsoring money and the other a table with sponsors sponsoring materials. It’s also possible a sponsor sponsors money AND materials.
The query has to display all the records from both tables.

SELECT * FROM table1
JOIN table2 ON table1.common = table2.common

OR

SELECT * FROM table1,table2
WHERE table1.common1 = table2.common1
AND table1.common2 = table2.common2
      .                .
      .                .

Common1 and common2 are the common fields between the tables.

detiege,
correct me if I'm wrong but a regular join will not include null values. it only includes those records where a match is found.  km3 specified that all records are returned.

detiegeCommented:
Yes, excuse me !
Replace JOIN by FULL JOIN.

If a row from either table does not match the selection criteria, specifies the row be included in the results set and its output columns that correspond to the other table be set to NULL.

AzraSound,

When I try a FULL JOIN, I get a Sytaxis-error with the component FROM

AzraSoundCommented:
SELECT * FROM (Table1 FULL JOIN Table2 ON Table1.Sponsor = Table2.Sponsor)

try it with parenthesis

km3Author Commented:
It still doesn't work. When I replace FULL for INNER or LEFTor RIGHT etc., I don't get an error but I don't get the right records either.

AzraSoundCommented:
yes you need full...dont know why its not supported..try one of these then:

SELECT * FROM (Table1 LEFT OUTER JOIN Table2 ON Table1.Sponsor = Table2.Sponsor)


SELECT * FROM (Table1 RIGHT OUTER JOIN Table2 ON Table1.Sponsor = Table2.Sponsor)

Your statement may read:
SELECT * FROM Table1 FULL OUTER JOIN Table2 ON Table1.Sponsor = Table2.Sponsor

Why don't you use a UNION query like this:

SELECT F1, F2, F3 FROM Table1
UNION
SELECT F1, F2, F3 FROM Table2
ORDER BY F1

comment on your comment, emoreau:
1) use rather UNION ALL that simple UNION, because of performance and to avoid duplicate records are eliminated

2) the tables are related by a field, so i don't think this is what he is looking for

angelIII,

The question is: «I want to combine two tables into one query, displaying all the records from both tables.»

This sounds to me a UNION query not a JOIN query!

Guy Hengel [angelIII / a3]Billing EngineerCommented:
For me, he looks for a list of sponsors (every sponsor listed once, eventually including some details), with the columns [SumOfSponsoredMaterial], [CountOfSponsoredMaterial], [SumOfSponsoredMoney], [CountOfSponsoredMoney]

I think there is no need to "shout" at each other, lets tell km3 what he really wants

I tried to use UNION but that doesn’t work either.

There's Table1:

Tabel1ID         SponsorID    Amount
1          1              fl 500,00
2          1              fl 600,00
3          2              fl 100,00

And Table2:

Tabel2ID         SponsorID   Material
1         1             car
2         3             flowers

And my query has to be:

SponsorID    Amount     Material
1           fl 500,00      
1           fl 600,00      
1                  car
2           fl 100,00      
3                  flowers

comment on my comment:

In the query, there are three colomns: SponsorID, Amount and Material. In the colomn Amount you should not see the materials and vice versa (It doesn't show that well in my previous comment)

Do you accept this now it is working?

You can use this Union Query:

SELECT Table1.SponsorID, Table1.Amount, '' as Material
FROM Table1

UNION ALL

SELECT Table2.SponsorID, 0 as Amount, Table2.Material
FROM Table2

ORDER BY SponsorID;
