Queries :: Access 2003 - Join Via Calculated Field
Apr 28, 2013
I'm stuck in Access 2003 - the group I am working with is unwilling to upgrade due to costs, and I've inherited this database (or I should say, a glorified spreadsheet), so unfortunately I am stuck with the tools that I have to use.
So I have Table A:MemberID (autonumber, Primary Key)
NameLast (Text)
NameFirst (Text)
TLBeginner (Yes/No) - Training level
TLIntermediate (Yes/No) - Training level
TLContinuing (Yes/No) - Training level
TLAdvanced (Yes/No) - Training level
I have created Query1 with the above table and added in a calculated field which essentially takes the training levels and converts it to a decimal number (basing it off a binary number of the 4-bits/Yes-no fields) with the calculated field below:
So the calculated field works great - Depending what training levels are selected or not selected, I get a range between 0 through 15.
Table B: I want a list of "friendly name" for the different training levels.
TLID (Number, No duplicates)
TLFriendlyText (Text)
So what I want to be able to do, is to have Query1, that will pull the training level text (TLFriendlyText) within the query based on the calculated field (TrLevelTxtID). The catch is, I can't seem to create a join between the two tables with the calculated field.
Ideally, I want the final query to pull, [NameFirst], [NameLast] from TableA and [TrLevelTxtID] (from TableB) based on the queries calculated field [TrLevelTxtID].
How best to achieve this with the Access 2003 limitations. Also, this query will only be used for reporting/mail merging so there are no update requirements or concerns.
I have a query that returns several calculated fields. One of them is simply derived by simple summation of the others. If this calculated field returns a negative number, I need it to show as a zero.
The only way I know how to do this is by an IIF statement :
Code: SELECT [fld1], [fld2], [fl3], ..... IIF(([fld1]-[fld2]-fld[3])<0,0,([fld1]-[fld2]-fld[3])) AS fld4 FROM...
(The above doesn't suggest that [fld1], [fld2] etc are calculated fields - I just wrote it like that for succintness - they calculate fine, there's no issue with them...)
Is there a more efficient way of doing this? I find IIF's a bit tardy, possibly because they evaluate for both True & False eventualities, regardless of the condition, and this query is going to run against a fairly large dataset so any performance lag is going to be exacerbated.
I have query , which has got 2 outer joins. The query is:
SELECT A.Project_ID, A.Title, A.comm1 AS Comments, A.Partner AS PM, A.Staff_Assigned AS TL, A.Contact_Name AS FL, A.MD, A.Status, A.Project_Type, ISNULL(B.Delivered_Date, B.Delivery_Date) AS Start_Date, ISNULL(C.Delivered_Date, C.Delivery_Date) AS End_Date FROM dbo.PROJECT A LEFT OUTER JOIN dbo.PROJDATE B ON A.Project_ID = B.Project_ID AND B.Date_Type = "Start Date" LEFT OUTER JOIN dbo.PROJDATE C ON A.Project_ID = C.Project_ID AND C.Date_Type = "End Date"
Can anybody help me out the error with this. I get an error : at dbo.PROJDATE B ON A.Project_ID = B.Project_ID AND B.Date_Type = "Start Date" .
Do I need to use any parantheris or change anthing.
I have a query which returns a calculated percent. I have ordered that in descending order, and now want to see the top 50. So (In Access 2010) I entered 50 into 'Return'. But it returns all of the records!
Is this because pct is a calculated field? How can I correct this? The SQL seems to be correct.
Code:
SELECT TOP 50 HeciFail1.POHECI, HeciFail1.POQTY, HeciFail1.FAILQTY, IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) AS PCT FROM HeciFail1 ORDER BY IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) DESC;
I have a query with a Date field for EndDate (the dates for end-of-week, Fridays in our case) and another field for Sales (number of sales, not dollars).I want to add 4 calculated fields that represent weeks and have the Sales appear in the correct column (field) for that date.So I will have columns for 10 July 15, 17 July 15, 24 July 15 and 31 July 15 and I want the Sales for each record to land in the correct date column, based on the EndDate column. (The 4 fields is just for the sake of the example, I will actually be having dozens of these calculated date fields).I tried to do it by setting up the 4 calculated fields like:
10Jul15: Sales and then adding Criteria like: EndDate = #10/07/2015# It doesnt work.
I am trying to execute the query below with multiple left joins because of the data I am trying to get back. The weird thing is sometimes it work and then sometimes it gives me a join expression error. It seems that access strangely removes brackets around the ON clauses. However even when I put those brackets back in this query it isn't working. why this query isn't running or why the brackets disappear in Access 2010.
SELECT Patients.[First Name] & " " & Patients.[Surname] AS Fullname , [Clinic Patient].[MYMOP ID] , NZ(MYMOPs.[MYMOP Date], [Clinic Patient].[First Appointment]) AS [MYMOP1 Date] , MYMOPs.Completed AS [MYMOP1 Completed]
occassionally i will run queries that have run before, the hourglass will turn on, then turn off, and access does nothing visible, but tack manager says its running 90% cpu. . .
any ideas on what is happening or i am doing wrong?
This is not the normal calculated fields in query's. What I want is different, I want it to be like
IFF(ShowID="A",[TotalSales],0)
Thing I have is, I want to know all the Total sales in on row that has Show A in it and then Total sales for Show B. Problem is, I have over 130 shows. How would do that?
I have a several fields, calculated, that break apart a string of text at every open and closed parentheses. They work like they are supposed to with no errors. However, I want to use the result of this particular field in a combo box to populate another combo box with the other half of the string that will be split. The problem, I think, is that since the field is calculated, it will not allow me to select it in the combo box, saying that the field can't be edited.
So, I added the same field names to the table that the query was built on, however when I run the query, it says that there is a syntax error with a comma in the code. If I take out the table in the query, (not using the SQL side, just the query builder), it works again with no problem.The text I am breaking apart looks like this: 1.234(a)(1)(A)(2)(b)(i)(-a-)
I need this field to break the text up at the (1) mark, so the code I am using looks like this:
Code: PrinSubChap1: IIf([Sub2] Is Null,[PrincipleNumber],Left([PrincipleNumber],InStr(InStr(1,[PrincipleNumber],"(")+3,[PrincipleNumber],")")-0))
The other fields I have do the exact same thing, written the same way, with adjustments made to the position (+3,0).I have stared at this for awhile and can't figure out why it is giving me an error and research on the web doesn't appear to cover my question.
This is the error message: Syntax error (comma) in query expression '[mytable].[IIf([Sub2] Is Null,[PrincipleNumber],Left([PrincipleNumber],InStr(InStr(1,[PrincipleNumber],"(")+3,[PrincipleNumber],")")-0))]
I Have some calculated fields in a query and want to update it in the table .So,is there anyway to store these fields.Otherwise can i store this Query data every month in database so that when i re-run the query the previous month data will not be affected.
I have been working on an access 2003 database for four weeks now and have been asked to create a field in a table that allows a user to select mutliple entries from a list. This information in this field of a table needs to be able to be queried and reported on in written and graphical reports.
I have tried and hit a brick wall any help with setting this up would be most appreciated.
I am currently using INNER JOIN and GROUP BY to narrow down the RowSource of a combo box based on the value selected in the active combo box where the code is located "onClick".
The value being selected is a StoreID, This ID is matched against the AssetRegister to find all group names, The GroupID and GroupName are then retrieved from the AssetGroup table, then finally the list is grouped on the Group ID and Group Name.
I have tested this query in SQL Server Management Studio and it works without any issues, however when I use it as an inline query to adjust the row source of the combo box it returns no values.
Here is the SQL query:
Code: SELECT AssetGroup.ID, AssetGroup.GroupName FROM AssetGroup INNER JOIN (SELECT AssetRegister.AssetGroup, AssetRegister.Store FROM AssetRegister WHERE AssetRegister.Store=7) AS ar ON (ar.AssetGroup = AssetGroup.ID) INNER JOIN Store ON Store.ID = ar.Store GROUP BY AssetGroup.ID, AssetGroup.GroupName ORDER BY AssetGroup.GroupName
And here is the inline query applied to the RowSource:
Code: AssetGroup.RowSource = "SELECT AssetGroup.ID, AssetGroup.GroupName FROM AssetGroup INNER JOIN " _ & "(SELECT AssetRegister.AssetGroup, AssetRegister.Store FROM AssetRegister WHERE AssetRegister.Store=" & StoreID & ") AS ar ON (ar.AssetGroup = AssetGroup.ID) " _ & "INNER JOIN Store ON Store.ID = ar.Store GROUP BY AssetGroup.ID, AssetGroup.GroupName ORDER BY AssetGroup.GroupName" AssetGroup.Requery
I am having a problem with calculating a date field in a query. Prior to this posting I've done some research and made several changes to my query. This only resulted in fixing one problem but then creating another problem. Original problem was I had 2 fields, arrived (23:36) and stemi (0:07). I use the following calculation AT_ST: DateDiff("n",[arrived],[stemi]) which resulted in -1409. So my research showed me I had a problem with the date whenever the time went past midnight and trying to calculate a zero hour number. I changed my calculation to
AT_ST: IIf([stemi]>=#11:59:00 PM#,(DateDiff("n",[arrived],[stemi])),(DateDiff("n",[arrived],[stemi]+1440) Mod 1440))
This works fine and gives me the result of 31 minutes which is what I want, however the problems comes in when I change to this calculation any where there was a negative time now has a 1400+ plus value. Such as arrived (7:37) and 1st_eck (7:18) = 1426 where as before it would report -14 (yes, negatives are acceptable for my reporting because sometimes a call to the hospital is placed before the patient arrives so we want to report on the negative splits). I've tried using a nested IIF to calculate for stemi time being less than arrived time, this didn't work when I tried to use it on the calculated query field. I was wondering if I could write something to check the value of the calculated field if it is greater than 1440 and if yes - subtract 1440 from it. So in the example above 1426-1440 = -14. Is it possible to do this within the query or do I need to do it using VBA
So I have the following query field which calculates another field.
How do I Filter the records in this calculated field to only return TRUE, as if I put "TRUE" in the Criteria for this field (or anything at all) then a parameter message box pops up asking for [Balance].
I want to calculate a field that is Sales*6+Salary, then in that same query I want to select ONLY the greatest Salary per employee. So for example
SELECT EmpId, MonthDate, Sales, Salary, [Sales]*6+[Salary] AS SalTot FROM EmpTable S1 WHERE SalTot = (SELECT MAX(SalTot) FROM EmpTable S2 WHERE S1.EmpId = S2.EmpId);
Can I not select a value that has been calculated this query?
I'm adding to a database that someone else set up. I went to the Design View page and clicked on one of the buttons at the bottom to add a text box etc etc. It all looks fine, but the field doesn't seem to be active - if I add some text into it for one page of the databse, the same text appears on every page of the databse. I notice that my "new field" is not listed in the fields list. How do I add it? I keep looking through "The Missing Manual" but without spending 3 days reading the whole thing (which I don't have time for) and learning much much more than I need to know just to get to the part that I need to know, it isn't helping me much.
Please can anyone enlighten me? My email is stu_paranormal@yahoo.co.uk
I'm using Access 2003 connecting through ODBC. I'm trying to set up an automated query to grab today's data. normally it's pretty easy, all you'd have to do is enter date() in the criteria in an access query. Unfortunately, the date in my database (i can't change this) is in an odd format.
example: april 1st, 2013 = 1130401
Every single date always has that preceding "1" in front of it, then the year, then the month, and finally the day.
I want to always specify the current date whenever the query is run (without having to type it in)
I can't get this to work! I am re-using a database to create new reporting. It was a technician utilization database that I am reworking to show weekend days worked. I changed the date format to Long Date to show the day, then started a query. The query is looking for *Saturday* but pulls nothing in the date field that I just changed to Long Date. What am I missing?
MS Office 2003..I have 7 queries that I use to export data to one excel workbook. Inside the workbook are 7 worksheets, one for each query. I have it working but I dont know how to save the exports steps like I did in AC2010.
I export the data by right clicking on each query and select export , then I browse to the workbook and because each query is named differently , it names the worksheet. I have to run these 7 queries each month , so I would like to save the steps and then build a macro that would run all seven steps at the push of a button.
I have saved the steps on a PC running MS office 2010 and the macro works great. The problem is this resides on a PC that cant be upgraded and I need to make it work on Access 2003 .
