Query to calculate chg & precent change between current record & record b4

Greetings SQL Guru's
I know that Oracle has analitical functions that can produce the results I need.
I have a view that will return four rows. I need to find the change and precent change between
the current number and the number before it.
The following is a example:
Year     EndOfYearRSF      ProjectedRent      Change           %change
2006     70000             1179226         -                    -
2007     75000             491015     -688210               41%
2008     80000             1188947     697931               42%
2009     90000             198502     9554                  .6%
[pre]
The operation is being performed on the ProjectedRent Column. I'm currently using Oracle 9.2
Thanks in advance

may be somthing like this
1 WITH t AS (SELECT 2006     year,70000 EOFYear,     1179226 rent from dual
2               union all
3               SELECT 2007   year,75000 EOFYear, 491015 rent from dual
4               union all
5               SELECT 2008   year,80000 EOFYear, 1188947 rent from dual
6               union all
7               SELECT 2009   year,90000 EOFYear, 198502 rent from dual)
8   select year,EOFYear,rent,rent-lag(rent,1,null)over(order by year )Change
9* from t
10 /
     YEAR    EOFYEAR       RENT     CHANGE
     2006      70000    1179226
     2007      75000     491015    -688211
     2008      80000    1188947     697932
     2009      90000     198502    -990445

Database changes between data records of PSA

Hi all,
Does anybody know a way, how to flush or commit database change between processing each data record from PSA by transfer rules?
I have some routines in transfer rules (updating attributes of master data from datasource), where I need values from exactly previously processed data record. But SELECT from /BIC/Q... table gives me no changes of these values
Command of selection is written correctly, because it gives me new values in next run of DTP process.
And little explanation, what I'm trying to achieve:
In PSA I have account, date and value and I need count, how this value changed for a concrete day and store this value to time-dependent attribute of master data. All data records with the same key (duplicate record) overwrite the result of previously one, so only last one is stored in master data.
Shortly, I need something like aggregation ADDING of routine in transfer rule detail, but able to catch duplicate records.
Thank you for any idea.
Regards, Filip

Some note about investigation process.
I tried change my data flow and made the same transfer rules from data source to ODS, if it will behave in different way.
I have found data records correctly collected (agregated) in New data of ODS, but EMPTY in active data! So I think, the something similar happend in case of updating master data, and that's why I didn't saw any agregation.
There is no need to call-out database changes, but this problem is kind od anythink else
This shoud be for a new thread, but how can keyfigures become empty after activation?? I've searched forum and found only a case, when End routines are implemented and they skip update rules, whitch are initial. This is not my case.
Nice to hear from you any ideas. Thankx for reading.

How to calculate the Percent change in a dynamic

hi All,
I'm trying to get the percent increase/change of two dynamic
colums. In my report, the user has a checkbox where he can select two colums to calculate the percent growth.
My DataSet is PilarName, Calification(is a decimal value) and Period (this is a string). I created the Matrix this way:
PilarName [Period]
[PilarName] [Calification]
Which give me these values:
So, now I need to create another column to calculate the percentage change between these two colums. I tried this:
I added a Adjacent column group for Period column and I grouped by the calculated column "ColumnDiff". Add the following expression.
=(SUM(Fields!Calificacion.Value)- Previous(SUM(Fields!Calificacion.Value),"ColumnDiff"))/Previous(SUM(Fields!Calificacion.Value),"ColumnDiff")
After that I get:
I'm getting the sum of the two columns instead.
Any clue about what I'm doing wrong? Please help me, I've been looking for the answer but any solution works for me.
Luis Carlos

Hi Luis,
According to your description, you have a report with different dynamic columns. Now what you want is show your user percentage growth in your matrix report after your user select two of those columns (I think you may use parameter to achieve your “checkbox”
function). Is my understanding correct?
In Reporting Service, we can’t calculate dynamic columns with our build-in arrogation functions. So we need to add custom code into our report, and call those functions which defined in custom code in our expression. We have tested your scenario in our local
environment. Here are steps and screenshots for your reference.
Go to your Report Properties, add the custom code below into your report:
Dim Shared Num1 As Double
Dim shared Num2 As Double
Public Function GetCalification(Calification as Double,Type as String,Type2 as String)
If Type = Type2 Then
Num1=Calification
Else
Num2=Calification
End If
Return Calification
End Function
Public Function GetPec()
Return (Num2-Num1)/Num1
End function
Create a matrix. Put PilarName into Row field, put Period into Column field. In Data field, put the expression below into the textbox:
=Code.GetCalification(Fields!Calification.Value,Fields!Period.Value,Parameters!Period.Value(0))
In our sample report, we created a parameter (named Period) for selecting two columns. You can replace “Parameters!Period.Value(0)” with your own parameter.
Add an outside column at right (%Growth), put the expression below into the textbox:
=Code.GetPec()
Save and preview. The matrix and result looks like below:

Formula to calculate number of days between today's date & given date BEx

Hello,
I have a date available as an attribute of dimension characteristic. How do I get current date (sy-datum) to calculate the # of days (or difference) between query execution date and given date.
Is there a system field to get current or today's date .
I am thinking to have this as calculated KF in BEx.
Any suggestions or tips
Thanks

Hi,
Create a variable on the attribute(date attribute) of characterstic. Use this variable to create a formula variable , in which you fin out the difference between current date and varaible.
There is a good document on using the attributes in the calculation in service.sap.com/bi
In infoindex--> calculation with attributes.

Changes between MII 12.0.2 and 12.0.9 (patch 7)

Hi,
We've upgraded one of our non-production MII environments from MII 12.0.2 (build 88) to 12.0.9 (build 23), and some of our dashboard apps are not working correctly.
One issue that I've tracked down sounds similar to this post: [Re: java.io.EOFException]
But is different. We have a BLS that has a local property (called Hold_qty) that acts as an accumulator of a QUANTITY value that is returned in multiple rows from the associated SQL query.
Under 12.0.2, Hold_qty is defined with data type String. There is a repeater, with an assignment that assigns Local.Hold_qty the value of Local.Hold_qty + Order_table.Output(/Row/QUANTITY). This worked fine on 12.0.2, as the String would be converted to integer automatically (with value 0), then would accumulate the QUANTITY values.
Now in 12.0.9 it is no longer working and the Hold_qty value is NA after the repeater is done. It seems that MII is no longer converting the string type to integer before attempting the addition, thus the addition is attempted with Hold_qty having string NULL value, instead of integer Zero value. Because it is null, then MII calculates the result to NA. The MII manual does state that "Calculations that include null values return a value of NA".
My question, is why did the precedence of type conversion vs. property evaluation change between the versions? Is this change documented somewhere? I didn't have very good luck finding a list of changes in all of the versions between 12.0.2 and 12.0.9. Can someone point out where I can find such a list? I searched SAP notes and it seems that only some of the SPs between 2 and 9 have Notes but not all of them.
I changed the data type of Local.Hold_qty to Integer in the BLS and now it works correctly on 12.0.9, but I'm still curious as to why the change, as using Strings instead of integers and allowing the type conversion was a recommended approach in at least one post in the past: [Integer with Value of NA??]
Thank you and best regards!

Hi Jeremy,
Thank you very much for providing the list of notes - that is VERY helpful. I reviewed the list and did see a couple that seem to be related to the issue that we are seeing.
Specifically:
Note 1168706 which is included in SP04. But this fix seems to imply that what we were doing in SP02 should still work.
Note 1435052 which is SP09 patch 4, says:
"3- In a MII Transaction, if you have an XML Document with a field of type integer, and when you assign it to "nullnumber", it doesn't show up in the Data as "NA". But it displays a number eg. "-2147483648".
This isn't exactly what we are seeing, but seems very closely related, so perhaps the fix for this issue is what is causing our problem? Perhaps this fix introduced a new bug?
What is the proper means of reporting a potential bug? Should I wait for confirmation in this forum?
Thank you again so much for your help. As a final suggestion, since your list of MII releases and the associated SAP Note numbers is so useful, would it be possible for you to create a sticky thread that lists all releases (with associated SAP note numbers)? Or maybe this is overkill due to the way they are listed in the download section of Service Marketplace? If so, please disregard.
Best regards,

Need the query to calculate the time taken to excute it.

hi all,
i need the query to calculate the time taken to excute it.
for ex:
select * from emp;
how much time it will take to give o/p
Thanks in advance
satya

Just to add to what was said - the execution can each time be DIFFERENT as the factors that governs performance are NOT CONSTANT.
If Oracle has no idea how long the query is going to take before executing it, then how can you and your code know?
Oracle's CBO estimates the cost (expense) of the query. This is an indication of how expensive a query is - and the more expensive the query, the more resources need to be used, the longer the query will take. The less expensive the query, the fewer resources it need, the faster it will take.
And that is it. How fast or how slow? Oracle does not know. How much faster a query with a cost of 10,000 versus a query with a cost of 1? Oracle does not know.
Why? Because the platform is not constant. Just what data is at this exact moment in the db buffer cache? Just how much CPU capacity is available for the new few seconds? Just what will the sustained throughput be of the I/O subsystem and channels for the next minute? Just how many memory pages need to be swapped between cache and memory? Etc. etc.
All these factors change every single second. So forget about attempting to accurately calculate up-front the time it will take for a query. IT IS NOT POSSIBLE.

Query to add a column in between existing cols of a table?

HI All,
I have two questions.
1. Query to add a column in between existing cols of a table? (not at the end. This is view of an order of output fields in a report)
2. How do I swap the contents of two columns in a table. Suppose in a table tab there are 2 cols , col1,col2 populated with some data.
I need a query(probably) to swap the col1 and col2 values . NOT AS A RESULT SET, BUT IT NEEDS TO GET CHANGED IN THE TABLE.
Please help !

> 1. Query to add a column in between existing cols of

Not really sensible ito DBMS - it does not care how you want to view the data. The sequence and formats of columns are what you/the application need to specify in the SQL's projection clause.
Also keep in mind to achieve this, the DBMS will need to rewrite the entire table to fit this new column in-between existing columns. This is not the best of ideas.
The projection of rows is dealt with SQL statements - not with the physical storage implementation.

Key figure comparision between current year and previous year

Hello collegues,
I have created a WEB Intelligence report with key figure ROI (return on investment which is calculated out of three other key figures (capital, revenue and costs). I would now like to calculate the percentage period (year) differences between key figure ROI - between current year (month) and previous year (month).
Do I have to add coding within a key figure formula within WEBI Rich Tech client or within universe builder.
The key figures were extracted from SAP BW and added to a universe which is basis for WEBI rich tech client report.
thanks and regards,
Christian

Hi Stratos,
so I see - i have to use the variable Editor and then define a measure and add coding in the formula field. Do you have an e-mail address ín order to send you the report and explain in more detail what I would like to see - here it is not possible to upload a report...
thanks and regards,
Christian

Moving to current record after execute query

Hi all,
I have a form where i can list all db jobs which can be start or stop.
for more details, form is having columns like jobs, current db status, action(start/stop drop down)
The user will view list of jobs in the screen and he straightly goes to a record and start (submit) the job using drop down for that record.
once they start/stop the job, execute query will fire to show the current status of the job.
Now going to my requirement,after execute query, I want to go to the record (job) which user has started the job .
Currently the cursor will go to first record.
Is there any oracle 10g AS property where i can get current record , put it in parameter and go to that record after execute query?
Is there any other way?
Regards,
Leonard

Hello,
If you are sure the record after query will keep the same position, you can before, store the current record in a number variable with Get_Block_Property( CURRENT_RECORD) built-in, then after query use the Go_Record() with stored number variable in parameter.
If you think that after re-query the record number can change, you have to loop through your records, then stop navidation while you find the corresponding key.

Best practise to detect changes between two tables

Hi,
I try to write a query, that shows me the differences between a table in my DWH and the table in the source system. It should show me new, deleted and updated rows.
My approach is to do a full outer join based on the key and then check if any of the columns changed (source.A!=DWH.A or Source.B!=DWH.B, etc.) to get the updated rows.
My problem is now that my table has millions of rows und more than 100 columns (number, nvarchar, etc.). So the query takes hours.
Is there any best practise solution to optimize that query, by rewriting it, setting indexes or using hash code? I played around with hash code, but it wasn't really faster.
(BTW: CDC, etc are not allowed)
Thanks for any ideas!

Color changes between library/develop and web module

Hi there,
when changing between modules library/develop and web the color of the pictures changes. That means, pictures become darker and the red/orange colors become more intensive. Back to the library, everything is o.k. Webgaleries also change, but not normal exports.
Until yesterday everything worked wonderful, but then I updated from 3.0 to 3.3 and now there´s no more WISYWYG for the webgaleries!
Somedbody out ther who can help?
Thank´s, Tom

First up, Develop is the most current preview. Library previews depend on the preview settings and if they've been zoomed into recently. Web exports sRGB Jpegs and I believe the webcache files that are generated for preview are also. If you're using a Flash Gallery, then there is no colour management happening.
Is your monitor calibrated?

Query to calculate time

hi all,
i have 2 udf field of type 'Time', StartTime and EndTime in order to catch the info of some process time.
again 2 fields of date in order to catch the range of days for the process goes.
like the following
Startdate | Enddate | Starttime | Endtime
15/04/09--| 16/04/09| 9:30- | ---14:00
Now i need a query to calculate the time differences in hrs. like the process runs thro 4 n half hrs a day and totally as per the table value the total run process time is 9 hrs.
How to bring out in query any one plz help...
Thank you so much,

Hi Yatsea, sorry tis time too its not reteiving correct answer, the values i gave over here is jus for example. but in real there may be many different values. So will be useful in case of providing the query taking in the field names plz.
i hav a work around working on . will write here, plz guide me to correct the query to get me correct answer.
in order to find the specific hrs between start and end time for 2 days,
1. can find first total days within start and end date (EndDate-StartDate) + 1 = 2
2. 2nd find the hrs between start and end time (EndTime-StartTime) = 4.30 hrs
3. after tht should multply the 2 values 2 * 4.30 = 8.60 which should round as 9 hrs
Select (datediff(day,enddate,startdate)+1) * (endtime-starttime)
will it help..? its not giving correct answer. may gone wrong wit time format. but this concept will give correct anawer i hope...
PLz...help me getting solution.

Part A:
I've done some restating of the question, and distributed the calculations among several fields, not all of which need to be included on the visible layout. Other than formatting the Date fields and moving the 'Completed Date' field and its label, I've left this in the default "Layout 1" produced by AppleWorks.
Field List:
Priority: Popup menu with six items: 00, J, D, 1, 2, 3 Defaults to 00
TL (time limit in months): Calculation: CHOOSE('Priority',0,1,3,4,6,12)
Received: Date. Option: Automatically insert today's date (ie. Date Record created) (may be edited)
Target Date: Calculation:
DATE(YEAR('Received')+INT(MONTH('Received')+'TL')/12,MOD(MONTH('Received')+'TL', 12),DAY('Received'))
Remaining (Days): Calculation: INT('Target Date'+1-NOW()) (see revision below)
Completed: Checkbox. Set default value to Unchecked.
Completed Date: Date: Entered manually
OnTarget: Calculation: IF('Completed',IF('Completed Date'<'Target Date',"On Target","Over"),IF(INT(NOW())>'Target Date',"Over","On Target"))
The On Target field shows the current status of the case while still open, and the state on the closing date when it was closed.
Having done that, I was unhappy with the Remaining field continuing to calculate an ever larger negative number after the case had been closed. Hence this revision below:
Remaining: Calculation: IF('Completed','Target Date'-'Completed Date',INT('Target Date'+1-NOW()))
Shows the number of days remaining while the case is open, the days remaining at completion if the case has been marked Completed and the completion date entered.
Rsults (and some further formatting of the Layout) below.
Part B:
You will need Subsummary parts when sorted on Completed and on On Target. Fields can appear on a Layout only once, so each subsummary part will need a separate Summary type field for each field to be summarized.

Barry
