Default Union Query Access 2007 SP2 MSO

I have a union query that keeps telling me that there is a data type
mismatch. When I first run the query everything is okay and it displays the
fields accordingly. Then using the record selector I tell it to go to the
last record. The query runs a little bit and then sends the error message
Data type mismatch in criteria expression. (Error 3464).

I have triple checked all the fields to make sure they are in the correct
order and have the correct data. I can run the query with any combination of
two queries and there is no problem. A check of the records reveals that each
query is compatible with the other. I have a Parts query with 44,905 records,
a Labor query with 49,956 records and a Sublets query with 11,239 records.
The only time I get the error is when I have three queries within the Union.
Parts and Sublet produce 561,144 records, Parts and Labor produce 94,861
records; Labor and Sublet produce 61,195 records all with no errors. My code
is listed below:

SELECT [WO Master Parts 03].BD, [WO Master Parts 03].Department, 1 AS
Segment, [WO Master Parts 03].WorkOrderUID, [WO Master Parts
03].WorkOrderNumber, [WO Master Parts 03].WOServiceUID, [WO Master Parts
03].Type, [WO Master Parts 03].NPD, [WO Master Parts 03].Total, [WO Master
Parts 03].Quantity, [WO Master Parts 03].StoreRoom, [WO Master Parts
03].PartNumber, Null AS StartDate, Null AS EndDate, Null AS HrTime
FROM [WO Master Parts 03]

UNION ALL SELECT [WO Master Labor 03].BD, [WO Master Labor 03].Department, 2
AS Segment, [WO Master Labor 03].WorkOrderUID, [WO Master Labor
03].WorkOrderNumber, [WO Master Labor 03].WOServiceUID, [WO Master Labor
03].Type, [WO Master Labor 03].NPD, [WO Master Labor 03].Total, Null AS
Quantity, Null AS StoreRoom, Null AS PartNumber, [WO Master Labor
03].StartDate, [WO Master Labor 03].EndDate, [WO Master Labor 03].HrTime
FROM [WO Master Labor 03]

UNION ALL SELECT [WO Master Sublet 03].BD, [WO Master Sublet 03].Department,
3 AS Segment, [WO Master Sublet 03].WorkOrderUID, [WO Master Sublet
03].WorkOrderNumber, [WO Master Sublet 03].WOServiceUID, [WO Master Sublet
03].Type, [WO Master Sublet 03].NPD, [WO Master Sublet 03].Total, Null AS
Quantity, Null AS StoreRoom, Null AS PartNumber, Null AS StartDate, Null AS
EndDate, Null AS HrTime
FROM [WO Master Sublet 03];

Can anyone assist me and tell me the error of my code?? Please

Default Union Query Access 2007 SP2 MSO

Are any of these field Memo datatypes? I've run into strange things with
corrupt memo fields before. If any are Memos, try removing those fields from
the SQL and see if the union query then works.

Actually that might be a good troubleshooting method for the rest of the
fields. Remove some of them and see what does or doesn't work.

Another thought would be to create a union query with just two of the
tables, which you say works, then create another union query based on this
plus the third table. You might try different combinations of this to see if
there is a problem with a particular table.

Jerry,

None of the fields are memo fields.

What I find strange is that any two combinations will run with no errors, it
is just when I add that third query is when it blows up?

I did try creating a union with two of the queries then writing a query
against the results of the union then tried to link the third query, same
results, would not work.

Is there a record limitation to a union query? I have another union query
that has three queries with no problem. This query I am attempting would be
over 100,000 records, do you think that might be a problem?

I am going to try and limit the size of the three query union to see if that
works.

Also on A2007, I just ran a simple union query on 3 tables that totaled
2,244,414 records with no problems. Going to the last record using the record
selector took a couple of minutes. These tables have 10 fields with various
data types.

SELECT * from cargo_tariff_backup
union all
SELECT * from cargo_tariff
union all
SELECT * from cargo_tariff2;

Maybe you should simplify the number of fields especially where you have to
insert the nulls and such.

Have you tried a compact and repair?

Jerry,

I think I found the problem: I removed the two fields StartDate and EndDate,
the query ran with no problems. Is the fact that Date is part of the field
name and date is a reserved word causing the problem?

In the morning I am going to rewrite the last queries and alias these two
fields and then try it again.

It's not a reserved word problem. It would need to be a plain old Date
without brackets around it for that to happen. However your Type field could
be a problem!

http://support.microsoft.com/kb/286335/

You should double check that those fields are a Date/time data types.

Maybe insert a bogus date like #1/1/1950# instead of Null for those tables
without those fields. See if the mixture of nulls and actual dates is the
problem.

Default Union Query Access 2007 SP2 MSO

Jerry,

I inserted #1/1/1800# in the Labor and Sublet query (these were nulled out)
of the StartDate and EndDate fields and the query ran with no problems. I
then removed the bogus date in the Sublet query (last query) and the query
ran with no problems. I then reinserted the bogus date in the Sublet query
and removed from the Parts query (first query) and the query crashed. It
seems that the parts query was the problem but yet when coupled with just the
Labor query it ran with no errors??

I know that it works, but have trouble as to why when any combination of two
queries worked without crashing, but by adding that third query it would
fail. The logic does not compute with me (I am very anal and have to
understand why things work or do not work versus just accepting that it works
this way, versus not). I was even going to convert the date to a serial
number and see if it would run, but will not waste any more time on this
issue. I can null out the bogus values once I get the union through the
process.

Thank you for all of your assistance in this matter.

Maybe insert a bogus date like #1/1/1950# instead of Null for those tables
without those fields. See if the mixture of nulls and actual dates is the
problem.

Jerry,

I think I found the problem: I removed the two fields StartDate and EndDate,
the query ran with no problems. Is the fact that Date is part of the field
name and date is a reserved word causing the problem?

In the morning I am going to rewrite the last queries and alias these two
fields and then try it again.

Maybe you should simplify the number of fields especially where you have to
insert the nulls and such.

Have you tried a compact and repair?

Jerry,

None of the fields are memo fields.

What I find strange is that any two combinations will run with no errors, it
is just when I add that third query is when it blows up?

I did try creating a union with two of the queries then writing a query
against the results of the union then tried to link the third query, same
results, would not work.

Is there a record limitation to a union query? I have another union query
that has three queries with no problem. This query I am attempting would be
over 100,000 records, do you think that might be a problem?

I am going to try and limit the size of the three query union to see if that
works.

Are any of these field Memo datatypes? I've run into strange things with
corrupt memo fields before. If any are Memos, try removing those fields from
the SQL and see if the union query then works.

Actually that might be a good troubleshooting method for the rest of the
fields. Remove some of them and see what does or doesn't work.

Another thought would be to create a union query with just two of the
tables, which you say works, then create another union query based on this
plus the third table. You might try different combinations of this to see if
there is a problem with a particular table.

I have triple checked all the fields to make sure they are in the correct

The only time I get the error is when I have three queries within the Union.
Parts and Sublet produce 561,144 records, Parts and Labor produce 94,861

Can anyone assist me and tell me the error of my code?? Please

Default Union Query Access 2007 SP2 MSO

Jerry,

Did some more checking found the following: the OBDC link for the Labor
query has both date fields as a General Date. However when I checked the SQL
table where these fields are located I found that the table data type is
datetime and that nulls were not permitted for the StartDate field. Could
this initial setting in the SQL table eventually cause the problem? This was
after a View in SQL and at least three layers of queries before the union
query. Logic tells me that if the no null setting in the table was going to
be a problem that it would manifest itself the first time a null was inserted
into this field. Another note, I had to remove both date fields before the
union query would work, so this tells me too that this may not be the problem.

It's not a reserved word problem. It would need to be a plain old Date
without brackets around it for that to happen. However your Type field could
be a problem!
