Hi,
A couple of guys on the SQL Server forum solved this one yesterday but
they used a FULL OUTER JOIN, which, little known to me is missing from
Accesss and therefore the JET engine. Can anyone suggest an Access
friendly version? I'd like to be able to see other fields from both
UNIONed tables. For instance :
Positions table:
Book SecurityNumber Description
A 001 Fred
B 002 Jim
B 003 Tom
D 005 Peg
E 006 Sally
Trades Table:
Book SecurityNumber Value
A 001 1000
A 001 3000
C 004 4000
E 006 8000
Output Should look like:
Book SecurityNumber Description Value
A 001 Fred 1000
B 002 Jim
B 003 Tom
C 004 4000
D 005 Peg
E 006 Sally 8000
The linking fields are Book and SecurityNumber via a:
SELECT SecurityNumber, Book FROM Trades UNION
SELECT SecurityNumber, Book from Positions;
Is this possible? Really I'd like to be able to generate a union
query that includes * from both tables and has nulls where a record is
missing from the other table.
Thanks in advance for any help given.

Here's my guess:
=============== =============== ============
SELECT p.Book, p.SecurityNumbe r, p.Description, t.Value
FROM Positions as p
LEFT JOIN Trades as t
ON (t.Book = p.Book) And (t.SecurityNumb er = p.SecurityNumbe r)
UNION ALL
SELECT t.Book, t.SecurityNumbe r, p.Description, t.Value
FROM Positions as p
RIGHT JOIN Trades as t
ON (t.Book = p.Book) And (t.SecurityNumb er = p.SecurityNumbe r)
WHERE p.Book Is Null
=============== =============== ============
The 1st Select gets all the records in Positions, whether they match
in Trades or not, and the 2nd Select gets all the records in Trades
that are not in Positons.

Thank you so much Tom, it works perfectly. Now to add another 300
JOINs to it ;)
Thanks again,
Andy.

I am using Access 2K as a front end to a MYSQL database.
I am trying to run a Union query on the MYSQL database. The query is (much
simplified)
SELECT as ID from faxdata UNION
SELECT as ID from letdata UNION
SELECT as ID FROM MEMODATA;
I get an ODBC error. The same query runs when the backend files are MDB
files and it runs with MYSQL if I only combine 2 tables.

How do you bind the output columns from a UNION query when the fields from

This one is difficult to explain, so I will cut it down to the basics.
I have a major table 'tblA' which has an autonum field 'ID-A' as primary key
(of no significance to users). 'tblA' contains many fields including
picture and memo fields. The main user-selectable field is 'NameA'.
There is also a crossreference table (let's call it 'tblB') which provides a
secondary method of accessing records in 'tblA'. The main fields in 'tblB'...

I have 2 separate queries, which effectively are the same except they
draw data from separate tables. Both tables are (design-wise)
identical, only the data is different. for each query, there are 2
tables with a standard LEFT JOIN. One field of the query is calculated,
looking for a NULL in one table, and then using a field from the second
table in that case. One query looks like this:

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
