Calculated fields in access query

Hi,
I made a report in .net (2008) and have as datasource a query from ms access. One of the fields is calculated in Access. In .net preview of data in the crystal report all of the data is showing. However when running the report this column is omitted. Even the heading of this column doesn't show.
Am I missing something here?
regards,
Henk

Hi,
I am using Oledb and as I pasted the sql in this post I did see the error. It was the grouping section in the query where the field missing was omitted.
Thanks for your reply which somehow did help.
regards,
Henk

Calculated field in a query

Hi,
To begin with I am just learning EJB and JAVA so please bear with me. I want to create a calculated field in a query from two fields in the table being queried, using SQL I would write the query like this:
SELECT ledgerdate, description, quantity, unitprice, [quantity*unitprice] FROM ledger
I have created a class called ViewLedger to contain my results, it has the following elements:
DATE ledgerdate,
STRING description,
INTEGER quantity,
BIGDECIMAL unitprice,
BIGDECIMAL amount
The query that I have been attempting that fails is:
SELECT NEW ViewLedger(l.ledgerdate, l.description, l.quantity, l.unitprice, l.quantity*l.unitprice) FROM Ledger l
The error says that there is an unexpected * in the query
The following do not work either:
SELECT NEW ViewLedger(l.ledgerdate, l.description, l.quantity, l.unitprice, (l.quantity*l.unitprice)) FROM Ledger l
The error says there is an unexpected ( in the query.
SELECT NEW ViewLedger(l.ledgerdate, l.description, l.quantity, l.unitprice, [l.quantity*l.unitprice]) FROM Ledger l
The error says there is an unexpected [ in the query.
Any help would be greatly appreciated.
Thanks.

I don't think JPQL allows functions (*) in the SELECT clause.
You can use a native SQL query as a workaround. If you are using EclipseLink or TopLink Essentials, you can also use a ReportQuery.

Inner Query relating to calculated field in main query

I have a query that has calculating fields in it.
What I am trying to do is Create another inner SELECT query similar to the one above but using the FP_Qty_Required calculated field in the main query?
Is this even possible?
Thanks in advance
Aaron

Sorry. I did that because it looked a mess when I pasted it in.
SELECT        P.ItemNumber, P.DeliveryWeek, D.StartDate AS WC_Date, S.SumOfSchedule_Qty, P.Planned_Production_Qty, P.Actual_Production_Qty, D.StartDate,
                         CASE WHEN S.SumofPartPallet < 0 THEN 'PART PALLET' ELSE '' END AS PartPallet, S.FirstOfIntouchRef, S.Pallet_Qty,
S.FirstOfTool_Number,
                         CAST(CASE WHEN S.SumOfSchedule_Qty > 0 THEN (S.SumOfSchedule_Qty - 1.0) / S.Pallet_Qty ELSE 0.00 END AS DECIMAL(18,
2)) AS DecNoOfPallets,
                         CEILING(CAST(CASE WHEN S.SumOfSchedule_Qty > 0 THEN (S.SumOfSchedule_Qty - 1.0) / S.Pallet_Qty ELSE 0.00 END
AS DECIMAL(18, 2))) AS QtyOfFullPallets,
                         CASE WHEN s.sumofpartpallet < 0 THEN s.sumofschedule_qty ELSE CEILING(CAST(CASE WHEN S.SumOfSchedule_Qty >
0 THEN (S.SumOfSchedule_Qty - 1.0)
                         / S.Pallet_Qty ELSE 0.00 END AS DECIMAL(18, 2))) * s.pallet_qty END AS FP_Qty_Required,
                             (SELECT        SUM(SumOfSchedule_Qty) AS Expr1
                               FROM            dbo.SumOfSchedDelivery
AS s2
                               WHERE        (ItemNumber = S.ItemNumber)
AND (DeliveryWeek <= S.DeliveryWeek)) AS Running_Sum,
FROM            dbo.Production AS P INNER JOIN
                         dbo.SumOfSchedDelivery AS S ON P.ItemNumber = S.ItemNumber AND P.DeliveryWeek = S.DeliveryWeek INNER JOIN
                         barcoding.dbo.DeliveryWeeks AS D ON P.DeliveryWeek = D.DeliveryWeek INNER JOIN
                         dbo.TotalRequiredByItem AS T ON S.ItemNumber = T.ItemNumber
The above works. What I want to do next is after the Running_Sum to add another sub query similar to this:
(SELECT        SUM(FP_Qty_Required) AS Expr2
                               FROM            ???
                               WHERE        (PD.ItemNumber = ItemNumber)
AND (PD.DeliveryWeek >= DeliveryWeek)) AS Running_FullPallet
FP_Qty_Required is a calculated field in the main query.

Possibility of a calculated field in a query.....

Dear All,
I have a query which displays some fields. One such field is 'Personel Area'. It contains the values such as P00123...etc and some imes with values such as A0234......etc.
I need to create a calculate field 'Y/N'. To populate this field the logic will be "if Personnel Area = A*, then Y else N'. I am not allowed to create this field in the cube, which could have solved my problem.
I need to do this at the query designer level only.
Points will be assigned.
Thanks,
Srinivas

Hi Srinivas,
You may determine the value of your variable through an if - else in ZXRSRU01 include residing under function exit_SAPLRRS0_001 enhancement RSR00001 (do it thru CMOD).

Add calculated field (Query - SQ01)

Hi to all,
I would know how can i add a calculated field to a Query (SQ01) ?
Can you give me an example of abap code to insert in CODING section ?
thks

Hi,
My understanding about your question is you want to display the total for two standard fields in a table,
1) Personalize the table and make true for the property Total.
2) If you want to calculate both the column total,
Add a MessageStyledText via personalziation to the page, and extend the controller
and in the ProcessRequest
Get the handle of the AM and then ur attributes VO Attributes and traverse through the VO rows and get the total of both the columns
and set the value to the newly created MessageStyledText.
Let me you want any sample code for the second step.
Thanks.

;Thank you,

Hi,
So you know how to compute iptv for an individual row; the problem now is that you want to get a running total of iptv; is that it?
The problem there is that computing iptv requires an analytic function, and analytic functions can't be nested. To get the results of nesting f (g (x)), where f and g are analytic funtions, you have to compute g in a sub-query, and then use the results as the argument to f in a super-query.
Here's how to apply that to your situation:

You asked for NULLS in the may11_rep, may11_bld and may11_iptv columns. You can get those results if you need them; just explain the rules that govern whether to display the values and when to display NULL.
The way you posted the sample data and results, and the quantity of sample data were all excellent; it really helped me find a solution. Thanks.
It would have also helped it you had explained how iptv is computed. Basically, iptv = 1000 * rep / tbld, right?
It looks like most of this code:
,      DECODE(NVL ( SUM (may11_bld)
                  OVER (ORDER BY dis DESC)
                ,                 0),0,0,ROUND(NVL(may11_rep, 0)*1000/ NVL ( SUM (may11_bld)
                  OVER (ORDER BY dis DESC)
                ,                 0),2
                ))        AS may11_iptvwas a way of avoiding divide by 0 errors; it would have been helpful if you had explained that.

Inserting calculated fields in database queries

I have just changed from using StarOffice version 7 to version 8.
I am having difficulties in creating a calculated field in a query.
Would anyone have some ideas for me to follow?
Thanks - Dan

1. Order as a column name could be problematical as it might conflict with the SQL 'ORDER BY'. Wrapping it in square brackets should cater for this.
2. You are missing some spaces.
3. The use of the arithmetical + operator could be problematical with dates as the string expressions, which might be interpreted as arithmetical expressions. The + operator is used rather than the ampersand concatenation operator to suppress
Nulls, but that's not the case here.
4. As you are only returning columns from one table you do not need to qualify the column names with the table name.
5. Defining a range as on or later than the start date and before the day following the end date is more reliable as it allows for rows with date/time values on the last day of the range with a non-zero time of day element, something you cannot rule out
with complete confidence unless you have taken specific steps in the table definition to disallow such values.
So taking these points into account:
strSQL6 = _
        "SELECT [Order], [OperWorkCenter], [Created on], " & _
        "[Actfinish date]," [Actfinish date]-[Created on] AS Delta " & _
        "FROM [WOMP Work Orders] " & _
        "WHERE [Created on] >= #" & FStartDate$ & "# " & _
         "AND [Created on] < #" & FEndDate$ & "# + 1"
The FStartDate$ and FEndDate$ values must of course be in US short date format or an otherwise internationally unambiguous format such as the
ISO standard date format of YYYY-MM-DD.

What is a Calculated Field?

Hi,
I have an assignment which requires me to use a 'calculated field' in a query.
Despite searching and looking in the books I have, I find no reference to the term.
I'm guessing that it may mean something like:-
WHERE CUSTOMER.CustomerID > 3 * min_orders
The " 3 * " being a calculated field.
Is this it? Or does it mean something else?
Many thanks for any assistance.

This question has nothing to do with the Installation forum....
Post this to the appropriate forum (Forms , Discoverer forum ..to name some).
Greetings...

How to insert calculated field in SQ01

I would like to add a calculated field in a query but can´t find any documentation.
the specific problem is that I would like to add a basic mark up on some costs.
can anyone help
Keel

Unless you need some very complex calculations, this may be done in SQ01. The process is not very intuitive though.
1) In SQ01, open the query in the change mode. Go to the Field Selection screen (the 3rd one).
2) If you need to use an existing field in calculation, give that field a "short name" (if you don't see the Short Name column, go to the menu Edit -> Short Names -> Switch On).
3) Now create a new field. Go to the menu Edit -> Local Field -> Create. Give the field some name and descrption. Choose the properties that you need and enter the Calculation Formula using the short name from step 2 (e.g. COST * 1.10 to add 10% to the COST field).
You can also add conditions and use more than one existing field. I always use those local fields to display the invoice value, because NETWR is always a positive number, but it should be displayed as negative for cancellations and credits.

Linking to an Access Database (accdb) - calculated field in query

Using Crystal Report v 14 we have a problem linking to an Access 2010 database (accdb file format).
We created a query in the Access database with a calculated field that we want to use to link with Great Pllains database. We can see the query using the database expert and the OLEDB (ADO) data source. The problem is that the calculated field in the Access query does not show in the link manager.
What is the best wat to link an Access table that has a job number containing hyphens (111-222-333) with the other database that has the job number stored without hyphens (111222333)? Why does our query solution not work?

Hi,
I'm not sure if this can be handled at the Database query level, however this can surely be handled from the report level.
You would need to insert a subreport with Great Pllains as its datasource. The Main report's data source would be the access table.
Next, in the Main report you would need to create a formula to remove the hyphens from the string and convert it back to number. Use this formula:
tonumber(replace(,"-",""));
You can then palce this formula in the details section/group section (which ever is applicable) and then link the subreports's job number field with this formula field. A record selection formula is automatically added in the subreport when you do so.
Also, make sure the sub-report is place in the same section this formula field is placed in, otherwise you can get unexpected results.
Hope this helps!

Using a "Sum" Calculated Field on a "Count" query column?

Here's my query using the Query Report Builder:
SELECT Col1, COUNT(Col1) AS Count_Column
FROM Table
GROUP BY Col1
It generates a report that lists all the values of column
"Col1" and how many times each value was used in Col1
For instance, if Col1 contained the value 'A' 12 times, 'B' 6
times, and 'C' 19 times, the report would generate this:
A - 12
B - 6
C - 19
What i need as a column footer is the total count of all the
values, which in this case 12+6+19=37
I am using a calculated field, setting the data type to
Double, the calcuation to Sum, and the perform calculation on to
'query.Count_Column'. Reset Field When is set to None.
When I run the report, it doubles the last number in the
report's Count column (19) and displays 38 on the page. I tested
this with another column and it doubled the last number in the
report as well.
How can I get it to properly Sum my Count_Column?

Hi,
You need to check note 208366.1 which explains why totals can be blank. Without knowing the detail of you decode function it is hard to say what needs to be changed. Try putting a sum in front of the decode e.g.
sum(decode(period, 'Jan period', value, 0))
Hope that helps,

Calculated Field is Disable while using PowerPivot to access multiple sheet column in a single pivot,

Hi,
I am trying to add a calculated field in my power pivot table to show the percentage on the basis of 2 columns, please let me know why this is not appearing and how can i fix it.
Any other way if i can add a calculated field in the pivot table will be very helpful.
Thanks
Aman

Thanks KR for the response,
Yes I loaded multiple tables in the data model and using PoewrPivot ,
i have a rating column, in that i have 0,1,2,3,4,5 rating numbers and we call it "Total expected occurrence",
a single person can get same rating multiple times, if a person is getting >=4 rating no. we call it "Occurrence >= 4". now i have to find out the total
count of "Occurrence >=4" for a particular person from "Total expected occurrence" column,
once will get the net "Occurrence >=4" for everyone, it should divide
"Occurrence >=4"/ "Total expected occurrence" to take out the percentage of rating 4 for a particular person
Best Wishes,

Answers - would like to use calculated field's name, not expression

Hi Everyone,
I'am trying to make several calculated fields in a single query in Answers. Each field references the previous one, and the expression of the first one is already 5 rows long.
Now I reference it in the second calculated field by using "Edit Formula" -> "Column" -> 'Colum name'.
My problem is, that it puts the expression of the previous field, not it's name. I have to use it for almost 10 times in this single expression, so -although it works fine- it is totally unreadable, and very hard to debug for example.
And after all, I should use this field again, in several next calculated fields.
Does anyobody have an idea, how to make calculated fields having only the name of referenced other fields in it?
The repo is set for ad hoc reporting also, so using session variables which need to be set in Administrator Tool, is not an option.
Thanks for help in advance.

Hi Venkat,
thanks for the response. It would work, no doubt, in this special case, the problem is, that users use the repo for ad-hoc reporting aswell (and they don't have access to repo administration of course), so one can count on it, that there would be a new request of this kind every day to change the repo with customized user variables. I would like to avoid this of course.
Having the name of a referenced field in a new expression would be a simple solution. Is it possible, that it can't be done?

SAP HANA calculation field

Hello,
I have a query on the new calculated field in SAP HANA. What is the usage of this field, what are the pre-requisites and potential case when it is recommended to use such fields? Do we need to have a calculative view to use the calcluated field or can it be used directly in ABAP code?
Kindly let me know. We are in the process of code optimization for HANA.
Best Regards,
Mohit

Hey Mohit,
can you please give a bit more details, e.g. documentation about what you refer to as "the new calculated field in SAP HANA".
Concerning the details of usage within HANA, i.e. whether you need a calculation view etc. you might have a look at the SAP Help (Introduction - SAP HANA SQL and System Views Reference - SAP Library)) or maybe directly in the HANA SQL reference (http://help.sap.de/hana/SAP_HANA_SQL_Script_Reference_en.pdf).
From my answer I think you can directly guess, that there's no way in directly accessing the calculated field from ABAP - except of course if you access it using native SQL (ADBC or EXEC SQL).
For code optimization in SAP HANA (from an ABAP developers perspective), you might want to have a look at our Open SAP course (ABAP Development for SAP HANA - Dr. Jasmin Gruschke and Jens Weiler) or in the documentation given in our "Get Started" Section of ABAP for SAP HANA namely ABAP for SAP HANA Reference Scenario and ABAP for SAP HANA Reference Scenario - AS ABAP 7.4 Support Packages.
In case you need more HANA (less ABAP) related information for your question, you might additionally contact the HANA experts on SAP HANA Developer Center.
Cheers,
Jasmin
