I have been struggling with this for hours. I am trying to update all values that have the same 'SHORT#'. If the 'SHORT#' is in 017_PolWpart2 I want this to be the value that updates the corresponding 'SHORT#' in 017_WithdrawalsYTD_changelater. This update query is just displaying zeroes, but these values are in fact non-zero.
So say 017_WithdrawalsYTD_changelater looks like this:
SHORT# WithdrawalsYTD
1 0
2 0
3 0
4 0
5 0
and 017_PolWpart2 looks like this:
SHORT# Sum_MTD_AGG
3 50
5 12
I want this:
SHORT# WithdrawalsYTD
1 0
2 0
3 50
4 0
5 12
But I get this:
SHORT# WithdrawalsYTD
1 0
2 0
3 0
4 0
5 0
I have attached the SQL for the Query below.
Thanks!
UPDATE 017_WithdrawalsYTD_changelater
INNER JOIN 017b_PolWpart2 ON [017_WithdrawalsYTD_changelater].[SHORT#] =
[017b_PolWpart2].[SHORT#]
SET [017_WithdrawalsYTD_changelater].WithdrawalsYTD = [017b_PolWpart2].[Sum_MTD_AGG];
EDIT:
As I must aggregate on the fly, I have tried to do so. Still getting all kinds off errors. Note the table 17a_PolicyWithdrawalMatch is of the form:
SHORT# MTG_AGG WithdrawalPeriod PolDurY
1 3 1 1
1 5 1 0
2 2 1 1
2 22 1 1
So I aggregate:
SHORT# MTG_AGG
1 3
2 24
And put these aggregated values in 017_WithdrawalsYTD_changelater.
I tried to this like so:
SELECT [017a_PolicyWithdrawalMatch].[SHORT#], Sum([017a_PolicyWithdrawalMatch].MTD_AGG) AS Sum_MTD_AGG
WHERE ((([017a_PolicyWithdrawalMatch].WithdrawalPeriod)=[017a_PolicyWithdrawalMatch].[PolDurY]))
GROUP BY [017a_PolicyWithdrawalMatch].[SHORT#]
UPDATE 017_WithdrawalsYTD_changelater INNER JOIN 017a_PolicyWithdrawalMatch ON [017_WithdrawalsYTD_changelater].[SHORT#] = [017a_PolicyWithdrawalMatch].[SHORT#] SET 017_WithdrawalsYTD_changelater.WithdrawalsYTD =Sum_MTD_AGG;
I am getting no luck... I get told SELECT statement is using a reserved word... :(
Consider heeding #June7's comments to avoid the use of saving aggregate data in a table as it redundantly uses storage resources since such data can be easily queried in real time. Plus, such aggregate values immediately become historical figures since it is saved inside a static table.
In MS Access, update queries must be sourced from updateable objects of which aggregate queries are not, being read-only types. Hence, they cannot be used in UPDATE statements.
However, if you really, really, really need to store aggregate data, consider using domain functions such as DSUM inside the UPDATE. Below assumes SHORT# is a string column.
UPDATE [017_WithdrawalsYTD_changelater] c
SET c.WithdrawalsYTD = DSUM("MTD_AGG", "[017a_PolicyWithdrawalMatch]",
"[SHORT#] = '" & c.[SHORT#] & "' AND WithdrawalPeriod = [PolDurY]")
Nonetheless, the aggregate value can be queried and refreshed to current values as needed. Also, notice the use of table aliases to reduce length of long table names:
SELECT m.[SHORT#], SUM(m.MTD_AGG) AS Sum_MTD_AGG
FROM [017a_PolicyWithdrawalMatch] m
WHERE m.WithdrawalPeriod = m.[PolDurY]
GROUP BY m.[SHORT#]

I have a query, let's call it qry_01, that produces a set of data similar to this:
ID N CN Sum
1 4 0 0
2 3 3 3
5 4 4 7
8 3 3 10
The values shown in this query actually come from a chain of queries and from a bunch of different tables.
The corrected value CN is calculated within the query, and counts N if the ID is not 1, and 0 if it is 1.
The Sum is the value I want to calculate by progressively summing up the CN values.
I tried to use DSUM, but I came out with nothing.
Can anyone please help me?
You could use a correlated subquery in the following way:
select t.id, t.n, t.cn, (select sum(u.cn) from qry_01 u where u.id <= t.id) as [sum]
from qry_01 t
I've been tasked with coming up with a solution for a problem that was found this morning. I have a query that I need to do some math with. I have three pertinent columns.
SELECT lQ.[QUANTITY], lQ.[FORM_FACTOR_ID], oQ.[INDIVIDUAL_PACKAGING]
FROM [dbo].[AOF_ORDER_LINE_QUEUE] as lQ
LEFT JOIN [dbo].[AOF_ORDER_QUEUE] AS oQ
ON lQ.[SALES_ORDER_NUMBER] = oQ.[SALES_ORDER_NUMBER]
I can see myself doing this in a loop easily in languages I know best. It doesn't seem that looping is a good thing to do in SQL based on some preliminary research so I am reaching out for suggestions.
I need to output a total value which is a conditional sum of lQ.[QUANTITY]. The condition is if oQ.[FORM_FACTOR_ID] is equal to 1 then the output for that particular row is equal to the value of lQ.[QUANTITY]. If oQ.[FORM_FACTOR_ID] is equal to 2 then if oQ.[INDIVIDUAL_PACKAGING] is true, then the output of that particular row in the query is equal to lQ.[QUANTITY]. If the value is false, then the output of that particular row in the query is divided by 2. The final output needs to be a single integer.
QUANTITY FORM_FACTOR_ID INDIVIDUAL_PACKAGING
4 2 1
5 1 1
I would need a query that outputs the value 7 for the above table.
QUANTITY FORM_FACTOR_ID INDIVIDUAL_PACKAGING
4 2 0
5 2 0
That same query needs to output 5 for the above table.
What would be the best way to go about doing this?
If I understand the question correctly, you just want conditional aggregation -- a CASE as an argument to SUM().
If I follow the logic, it would look like:
SELECT SUM(CASE WHEN oq.FORM_FACTOR_ID = 1 THEN lQ.QUANTITY
WHEN oQ.FORM_FACTOR_ID = 2 AND oQ.INDIVIDUAL_PACKAGING = 1 THEN lQ.QUANTITY
WHEN oQ.FORM_FACTOR_ID = 2 AND oQ.INDIVIDUAL_PACKAGING = 0 THEN lQ.QUANTITY / 2
END)
FROM [dbo].[AOF_ORDER_LINE_QUEUE] lQ LEFT JOIN
[dbo].[AOF_ORDER_QUEUE] oQ
ON lQ.[SALES_ORDER_NUMBER] = oQ.[SALES_ORDER_NUMBER];
I have 2 tables I am combining and that works but I think I designed the second table wrong as I have a column for each item of what really is a multiple choice question. The query is this:
select Count(n.ID) as MemCount, u.Pay1Click, u.PayMailCC, u.PayMailCheck, u.PayPhoneACH, u.PayPhoneCC, u.PayWuFoo
from name as n inner join
UD_Demo_ORG as u on n.ID = u.ID
where n.MEMBER_TYPE like 'ORG_%' and n.CATEGORY not like '%_2' and
(u.Pay1Click = '1' or u.PayMailCC = '1' or u.PayMailCheck = '1' or u.PayPhoneACH = '1' or u.PayPhoneCC = '1' or u.PayWuFoo = '1')
group by u.Pay1Click, u.PayMailCC, u.PayMailCheck, u.PayPhoneACH, u.PayPhoneCC, u.PayWuFoo
The results come up like this:
Count Pay1Click PayMailCC PayMailCheck PayPhoneACH PayPhoneCC PayWuFoo
8 0 0 0 0 0 1
25 0 0 0 0 1 0
8 0 0 0 1 0 0
99 0 0 1 0 0 0
11 0 1 0 0 0 0
So the question is, how can I get this to 2 columns, Count and then the headers of the next 6 headers so the results look like this:
Count PaymentType
8 PayWuFoo
25 PayPhoneCC
8 PayPhoneACH
99 PayMailCheck
11 PayMailCC
Thanks.
Try this one
Select Count,
CASE WHEN Pay1Click=1 THEN 'Pay1Click'
PayMailCC=1 THEN ' PayMailCC'
PayMailCheck=1 THEN 'PayMailCheck'
PayPhoneACH=1 THEN 'PayPhoneACH'
PayPhoneCC=1 THEN 'PayPhoneCC'
PayWuFoo=1 THEN 'PayWuFoo'
END as PaymentType
FROM ......
I think indeed you made a mistake in the structure of the second table. Instead of creating a row for each multiple choice question, i would suggest transforming all those columns to a 'answer' column, so you would have the actual name of the alternative as the record in that column.
But for this, you have to change the structure of your tables, and change the way the table is populated. you should get the name of the alternative checked and put it into your table.
More on this, you could care for repetitive data in your table, so writing over and over again the same string could make your table grow larger.
if there are other things implied to the answer, other informations in the UD_Demo_ORG table, then you can normalize the table, creating a payment_dimension table or something like this, give your alternatives an ID such as
ID PaymentType OtherInfo(description, etc)...
1 PayWuFoo ...
2 PayPhoneCC ...
3 PayPhoneACH ...
4 PayMailCheck ...
5 PayMailCC ...
This is called a dimension table, and then in your records, you would have the ID of the payment type, and not the information you don't need.
So instead of a big result set, maybe you could simplify by much your query and have just
Count PaymentId
8 1
25 2
8 3
99 4
11 5
as a result set. it would make the query faster too, and if you need other information, you can then join the table and get it.
BUT if the only field you would have is the name, perhaps you could use the paymentType as the "id" in this case... just consider it. It is scalable if you separate to a dimension table.

Hi I'm working on a project and for time constraint reasons I need to keep working in Access which may be the root of all my problems but maybe there's hope.
I have a database that includes a table ANSWERS filled with input for users "wants" there are multiple columns which each correspond to an answer to a different question asking if they, Don't Care, Want, or Need something.
EG: Answers:
Bacon | Ham | Sausage
________________________________
1 0 0 2
2 2 1 0
3 0 2 0
4 1 1 1
(0 = Don't Care, 1 = Want, 2 = Need)
I want to compare a row from table Answers to the Available table.
EG: Available:
Bacon | Ham | Sausage
________________________________
1 0 1 0
2 0 0 0
3 1 1 1
4 1 1 0
(0 = Unavailable, 1 = Available)
So I would want to compare row 1 from Answers to Available so because row 1 includes sausage=2 then I would want to receive row 3 from Available because sausage=1.
I'd be happy receiving the entire row, or the row ID and a "1" for the rows being a match.
Ultimately I'd need to do this for all each of the rows in Answers.
Any ideas are appreciated, I was thinking using Intersect might work but since that doesn't work in access. I've also considered joining the tables, I could also change data variables or formats if necessary.
Thanks very much
Edit: Don't Care was previously Don't Want. Changed for clarity.
Give this a try:
SELECT tblAnswers.UserID, IIf([tblAnswers].[bacon]>0 And [tblMenus].[Bacon]<>0,[MenuID],Null) AS BaconMenu, IIf([tblAnswers].[Ham]>0 And [tblMenus].[Ham]<>0,[MenuID],Null) AS HamMenu, IIf([tblAnswers].[Sausage]>0 And [tblMenus].[Sausage]<>0,[MenuID],Null) AS SausageMenu
FROM tblAnswers, tblMenus
WHERE (((IIf([tblAnswers].[bacon]>0 And [tblMenus].[Bacon]<>0,[MenuID],Null)) Is Not Null)) OR (((IIf([tblAnswers].[Ham]>0 And [tblMenus].[Ham]<>0,[MenuID],Null)) Is Not Null)) OR (((IIf([tblAnswers].[Sausage]>0 And [tblMenus].[Sausage]<>0,[MenuID],Null)) Is Not Null));
Just paste that into a SQL view make Query window (After changing the table and column names to match yours) You will obviously need to tweak it as reality needs, but it does what you asked for with the data provided.
How can I select every thrid row from the table?
if a table has
1
2
3
4
5
6
7
8
9
records
it should pick up 3, 6,9 record. regards less what their data is.
Modulo is what you want...
Assuming contiguous values:
SELECT *
FROM Mytable
WHERE [TheColumn] Mod 3 = 0
And with gaps
SELECT *
FROM Mytable
WHERE DCount("TheColumn", "table", "TheColumn <= " & [TheColumn]) Mod 3 = 0
Edit: To exclude every 3rd record, ...Mod 3 <> 0
If its SQL you could use the row_number and over commands. see this, then where rownumvar % 3 =0 but not sure if that works in access.
Or you could put the table into a recordset and iterate through checking the index for % 3=0 if your using any kind of code.
How about a Count() on a field that has unique members. (id?) then % 3 on that.
