i have a question, I want to display in a Datagrid in Flex some information of this Combobox: http://puu.sh/bU6ht/ee36ed7fd1.png
N/A = 0
B = 1
M = 2
NT = 3
FS = 4
ER = 5
SSE = 6
And is saved in the Database as int, but I want in the Datagrid display the information as String
http://puu.sh/bU6cR/3c112d85e3.png
I have a solution and is doing a Case in SQL, but i dont know if is the correct solution.
CASE insp._manguera
WHEN 0 THEN 'N/A'
WHEN 1 THEN 'B'
WHEN 2 THEN 'M'
WHEN 3 THEN 'NT'
WHEN 4 THEN 'FS'
WHEN 5 THEN 'ER'
WHEN 6 THEN 'SSE'
END as _manguera,
And do that for every field in the database
You could also have a table in which you could associate the values to letters and do a join on that table.
That way, you wouldn't need to repeat that code anywhere and you could always modify the table. Good for long time use and reuse.
tell me if you need an example :)

I am trying to filter the data according to several criteria, and based on these criteria, the record record number 7 (M08) should not appear because the "NewSiteID" column is not null and does not belong to the number 6, but the problem is that this record appears even though I used the conditions that appear in the query.
tbMachines.MachIsTransfered, tbMachines.NewSiteID
FROM tbMachines
WHERE BranchID = 6 AND MachIsTransfered = 0
OR BranchID = 6 AND MachIsBorrowed = 1
OR BranchID = 6 AND MachIsloaning = 1
AND NewSiteID = 6 OR NewSiteID = '' ```

You need to use parenthesis around your conditions. In this case it can also be simplified quite a bit. If I understand what you are trying to do it could be something like this.
WHERE BranchID = 6
AND
(
MachIsTransfered = 0
OR
MachIsBorrowed = 1
OR
MachIsloaning = 1
)
AND NewSiteID in (6, '')
once more I need some assistance. I have one table called Data and contains cars with color and type.
I have one table called "output" and I want the color number appearing per "CARid" (when type='new') and the total colors per ID.
I tried to do it with "case" but it seems impossible to do it in one sql code. Do I need a temp table and then join?
data
carID color type
1 red new
2 blue old
3 red new
2 green new
2 blue new
1 red old
4 empty empty
output
CarID NColor ColorTotal
1 1 2
2 2 3
3 1 1
4 0 0
Some basic aggregation and a case expression should return what I think you are after. But no idea where CarID 4 comes from, it isn't in your sample data.
select CarID
, NColor = sum(case when type = 'new' then 1 end)
, ColorTotal = count(*)
from Data
group by CarID
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 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.
