UNION Query Using For Comparing?
Oct 2, 2007
Hello again...
Is it possible to use a UNION query for comparison between to tables or queries?
If so, please advise how to
example:
one query consists of a selection of books, grouped by category for a student
the second query consists of all books, grouped by category for a student
The purpose of the new union query is to check if the student has all the applicable books in his booklist; if the student has forgotten to pick a book for his list, this new query will show the one(s) the student forgot.
Kind of cryptical this example, hope i could make it clear enough...

I'm having a problem with a UNION / UNION ALL query.It seems there is a application crash fault when running the query that MS are aware of and have issued a hot fix. Unfortunately it will take my IT dept some time to check and install the hot fix If they agree to do it at all.
Problem signature:
Problem Event Name: APPCRASH
Application Name: MSACCESS.EXE
Application Version: 12.0.6606.1000

I'm trying to write a report which initially I didnt think would be hard to do, but when it came time to write the underlying query I realized it was a bit above me.
I cant give away too much of the database structure here, due to legal issues, so sorry for being vauge. Hopefully I can give enough information that someone can get me started.
I have three tables that will be used in this query. One is called NAMES and has all of personal details of contacts. The only fields that are needed from this table are the primary key and citizenship field.
The other two tables are virtually the same, and they are the two being compared. One is REGISTRATION and the other APPLICATION. Essentially what I want here is to be able to compare the number of who applied to the number who actually registered.
Here are the pseudo-tables to give you a better picture:
NAMES
nID
FName
LName
DoB
Citizenship
REGISTERED
programCode
startDate
endDate
nID (foreign key)
APPLIED
programCode
startDate
endDate
nID (foreign key)
I've tried a few different approaches which worked in my head, but when it came time to run the query the results were different. Any suggestions on how I should tackle this?

I want to compare two queries as follows: Select all the records in query1 where the value in fieldA does NOT also appear in any record in fieldA of query2. Is there an easy way to do this using the query tools or will this require a vba function?

is it possible to compare values in 2 different rows? for example if the query returns this:
1 | $5.00
2 | $6.00
3 | $20.00
4 | $30.00
i want to find out the cost difference between 1 and 2 which will be $6-$5 and then 2 and 3 which will be $20-$6 and so on. how can i make this happen in SQL? any suggestions?

Okay I have a query that pulls from a table. It's pretty simple - nothing big.The query will be used to correct information in some sales tax data.I have 3 colums with sales tax info, and they should all be the same. I want to compare each column to show only those which don't match each other.NetTax, TotalTax, and TaxB are the fields.In the query, for the criteria of NetTax, I put in:<> [TotalTax]When I run the query, I get results, but they are all equal.EG:4.35 4.35 4.35I don't want them to show, and not sure if that's the right way to go about it or what.If I run without that criteria, I get 21,600 results.With that in the criteria, I get 304 results. So it is working somewhat...but for whatever reason some don't seem to be seen as being equal? I don't get it. Data type is number and they are formatted the same way.

Hi...
I will try to keep this succinct.
I have a query that totals a column in a sub-form. The query also gets a sum from the main form for the same record. Is it possible to have a message/colour change/warning if the total of the column in the sub-form exceeds the other number in the query? I would need this comparison to take place within this query, rather than creating a new one.
Thanks!

I have 4 tables (one for each quarters data) each with the same fields:
Fund
FundFamily
Value
I have a query for each table that sums the values for each FundFamily (if there are multiple funds with the same FundFamily, it only shows the sum for the Family).
I am wanting a query that will show all of the different FundFamily fields from each table, but only once (say there is a Value in one quarter, but not the next). How is the best way to go about this?
Does what I'm trying to do here make sense?

Hi
I have such situation:
i have tables [k] and [r] with street and city field.
I would like set on field[dubel] in the second table [r] in the rows where the street and the city are the same for the both tables.
There could be one to many relations. It means many fields in [k] could have the same as in [r]
I've tried with this query but it marks all the fields....
UPDATE r SET dubel=1 where EXISTS ( SELECT r.str, cit
FROM k, r
WHERE (([k].[str]=[r].[str]) AND ([k].[cit]=[r].[cit])));
when i'm using just select part, it gives me good results.....
Can Anyone help ME?
THANKS

Hello All,
I'm trying to run a UNION query that joins five queries through a MS WorkSpace into a DAO.recordset in VB. I'm pulling the data from a SQL Server Database through VB in Access. I'm attempting to open a recordset with a query passed to it as a string. The query is below. For some reason, I'm receiving a message: "MS Jet database engine cannot find the input table or query. Runtime Error 3078".
Here's what's puzzling. When I run a single query without any UNION statement, the code finds the table and runs fine without error, but anytime I join two or more queries with a UNION statement in the VB, it gives me the error.
I've executed the same UNION query in both Access Query Builder and SQL Server's Query Analyzer and they work fine in both environments. It's only when I call the query from a DAO.Recodset with VB that it causes this problem. The following is a sample of the UNION query joining two of the five queries. Does anyone have any idea what could be the problem? The following query executes in about 5 seconds so I don't think there's a "time-out" issue. I'm thinking that the UNION statement may be the culprit. Maybe there's another way to approach joining these separate queries? Any help would be most appreciated. Thanks.

Hi there,
I'm trying to 'rank' x5 categories that overlap. To determine the ranking i'm utilising date & time (if the dates are equal). I've managed to do this comparing x2 of the categories but struggling with the logic for x3,x4 & x5 categories
I have the data in separate tables by category date & time and in one large table.
Hoping someone can assist as my head is starting to hurt.
Thanks

I need to identify pairs of records by their ID and date fields, then compare their number values to get a text result.
I have a query that has the following fields
AuthInstanceID, ConsumerID, AuthNumberID, AuthStart, AuthEnd, PSRUnits, BSTUnits.
Sample data is below (PSRChange and BSTChange are fields I want to self populate based on the comparison I'm trying to do)
AuthInstanceID....ConsumerID....AuthNumberID....Au thStart....AuthEnd....PSRUnits....BSTUnits - PSRChange -BSTChange
1374006036.........356679..........20255102....... ....4/22/13.......7/21/13....0.............416~~~~-Loss~~~~~-None
-432536491.........356679...........20255102....... ...1/21/13.......4/21/13....104..........416~~~~-Loss~~~~~-Loss
-124970517.........356679...........20147863....... ...10/23/12.....1/20/13....208..........520~~~~-None~~~~~-Null
504564357...........469432..........20254788...... ....4/22/13.......7/21/13....0.............520~~~~-None~~~~~-None
282523535...........469432..........20254788...... ....1/21/13.......4/21/13....0.............520~~~~-None~~~~~-Gain
356661326...........469432..........20254788...... ....11/20/12......1/20/13....0.............416~~~~-None~~~~~-Null
What I need to do is compare these records in the following fashion:
Identify pairs of records where ConsumerID is the same AND AuthStart dates are successive. Then compare PSRUnits of more recent record (by AuthStart) with the previous record (by AuthStart) and determine the change of PSRUnits between them. If change is positive, "Gain" in field PSRChange, "Loss" for a loss, "None" for no change, and "Null" if there is an error due to no previous record to compare with. Do the same with BSTUnits/BSTChange
I've tried adding the following fields, but this did not work
PrevEnd: (Select Max(AuthEnd) from tblAuthorizations Where AuthEnd < Auths.[AuthStart])
PrevBST: DLookUp("[BSTUnits]","tblAuthorizations","AuthEnd=" & [PrevEnd] And "ConsumerID=" & [ConsumerID])

I have created a report that provides me with employee expenses for temps per week. The types of expenses have been defined as Ad_hoc amounts.
An SQL union query I have used to combine fields
Adhoc_Code_1 - 3
Adhoc_description_1 - 3
Adhoc_Pay_Amount_1 - 3
(details of full sql query below)
I have tried to run for a particular week which should have 3 expense entries but only 2 have been picked up.
I think this is because both Adhoc_ Pay_Amount_2 and 3 have a value of 6 and the UNION operation will not return duplicate records. I have amended to UNION ALL but all entries are duplicated. Can anyone help?

OK, so I am UNIONing two tables using UNION ALL. It works fine. The resultant table has 192 records (63 + 129).
If a use just UNION or UNION DISTINCT I get 184 records. I'm pretty sure that is telling me that 8 records (192 - 184) exist in both tables.
How do I query to find out what those 8 records are?? I'm trying to use an INTERSECT in MS Access, but it doesn't want to work. Here is my original query:
select * from qryMOE_Active_All
UNION ALL select * from qryMOE_Closed_All;
Thanks,
Brian

I am a basic access user so please forgive my ignorance. I have created a union query of three tables. There is one field from the third table that I would like to have in the final table but this field does not exist in the first table. If I put "none" in the first SELECT line, then it queries correctly but the field name on the table is "Expr1006". If I put "Field 2" or [Field 2] in that same space of the first SELECT line, then it asks me for a parameter value and whatever I enter it fills in all the cells of that field with that value. I just don't know that language very well or even if you can add a new field into the first SELECT table. Thank you for any thoughts
Ex: SELECT [Field 1], [Field 2], "none", [Field 3]
FROm [Table 1]
UNION
SELECT [Field 1], "none", [Field 2], [Field 3]
FROM [Table 2]

Okay, people. I am getting married in a few days and my mind is on other things. Consequently, I can't get my head around this one.
I have two queries, Query1 and Query2. Both have a different number of fields but they have the field "IA Code" in common.
I want to create a new query containing all rows from Query1 and all rows from Query2. Where the [IA Code] matches, I'd like the information to be displayed in one row.
I think I need to use Union somewhere along the lines, but I can't work it out.
Any pointers/syntax greatly appreciated.

I have 2 tables with employee details in it. There is no natural link between the 2. I wish to write a query that will sum up the total pay for both tables.
I've had a look through the forum and it seems that a Union query is probably best.
I haven't worked with Unions before, so I did 2 sub queries to total the pay in both table and then union the 2 queries. I did this because there are some date parameters that I query each table by so I do this in the sub queries.
This works but I get 2 outputs in the result, the total pay from each table. I wanted to have just one output, which is the sum of all pay.
Can anyone help please.
SQL:
SELECT QrySub_TotalPay1.TotalPay 'sub query that sums up table 1
FROM QrySub_TotalPay1
UNION SELECT QrySub_TotalPay2.TotalPay 'sub query that sums up table 2
FROM QrySub_TotalPay2;
TIA.

I have 2 tables and I m trying to get sum of qty for each product
I tried union qurey following way but doesn't work.
Product_Master table has primary key set up on productcode. I need to pick up OpeningBal along with ProductName and ProductCode from this table.
T_PurInvFoot table contains multiple records of the similar ProductCode. I want to make sum of these PurQty data and add it with OpeningBal data from Product_master table and present it in one line.
The avalable quanities are in 2 diff. tables are here.
Product_Master.OpeningBal=5
(1 Record)
T_PurInvFoot.PurQty =4
T_PurInvFoot.PurQty =6
(2 Records)
So total it should be 15 when it produce records. But it show only 10 records from below query.
SELECT Product_Master.ProductCode, Product_Master.ProductName,Sum(Product_Master.Open ingBal) as Stock
From Product_Master INNER JOIN T_PurInvFoot ON T_PurInvFoot.ProductCode=Product_Master.ProductCod e
Group By Product_Master.ProductCode,Product_Master.ProductN ame
UNION Select T_PurInvFoot.ProductCode, T_PurInvFoot.ProductName, sum(T_PurInvFoot.PurQty) as Stock
From T_PurInvFoot INNER JOIN Product_Master ON T_PurInvFoot.ProductCode=Product_Master.ProductCod e
Group By T_PurInvFoot.ProductCode,T_PurInvFoot.ProductName
ORDER BY Product_Master.ProductCode;
Can somebody advice me how to do it.
I need to add 3rd table here in future to get sum of the qty of the similar ProductCode so how to the query would be?
One more thing, can we do it in VBA and set the RecordSource to a form or report ?
With kind regards,

I have two tables with data and I want to join the data together for a report.
Example:
SELECT tbl1.a tbl1.b tbl1.c tbl1.d
FROM tbl1
UNION SELECT tbl2.a tbl2.b tbl2.c
FROM tbl2;
Currently I can't join them b/c the column counts aren't the same.
If table1 has more columns than table2 can I join them by indicating some kind of phantom column 'd' for table2 to be joined to column 'd' of table1?

Will you help me built a union query ? I have 2 queries, qryinput and qryoutput.Out of these query i have a third query called qryDiff substracting these
queries. However qryDiff does not show all the goods sold, only those goods that are substracted.Therefore i want to build an union query but somehow i cannot do it. Will you help ?
My first query, qryinput is :
SELECT [order details].ProductID, Sum([order details].Quantity) AS Sum1, orders.orderid
FROM (orders INNER JOIN [order details] ON orders.orderid = [order details].OrderID) INNER JOIN products ON [order details].ProductID = products.Productid
GROUP BY [order details].ProductID, orders.orderid;
My second query, qryoutput is :
SELECT [order details].ProductID, orders.orderid, [order details].Quantity AS Sum2
FROM ((orders INNER JOIN [order details] ON orders.orderid = [order details].OrderID) INNER JOIN Customers ON orders.customerid = Customers.Customerid) INNER JOIN products ON [order details].ProductID = products.Productid;
My thirs query, qryDiff is :
SELECT qryProducts.ProductID, Sum(qryInput.Sum1) AS imported, Sum(qryOutput.Sum2) AS exported
FROM (qryProducts LEFT JOIN qryInput ON qryProducts.ProductID = qryInput.ProductID) LEFT JOIN qryOutput ON qryProducts.ProductID = qryOutput.ProductID
GROUP BY qryProducts.ProductID;
Now i want to convert the query qryDiff into an union query, but i cannot do it.I somehow managed to build a simple query showing all the products:
SELECT ProductID
FROM qryInput
UNION SELECT ProductID
FROM qryOutput;
This query shows the productsid indeed, but i cannot add the other items form the qryinput and qryoutput as the sum etc.
I also i cannot convert my query qryDiff into an uinion query, with fields for the imported and the exported sums and also for the product names.
Where is my error and now could i achieve my aim? My aim is that in the query qryDiff to show all the products, and not only the products sold.
I will be very grateful for any comments
