Attribute value of previous row

Hi
I have a read only VO.
I need attribute value of previous row .
how can i get it ?
consider these 3 attributes and their values :
Id ** add ** sum
1 *** 10 *** 10 -- > (value of previous sum + new value of add)
2 *** 20 *** 10 + 20 = 30 -- > (value of previous sum + new value of add)
3 *** 30 *** 30 + 30 = 60 -- > (value of previous sum + new value of add)
now , i write a method in impl and call this method in page def by invoke action .
i used Row[] rows = this.getViewObject().getAllRowsInRange(); in my method.
but i am looking for better solution.

Hi,
If you wanted to do a running total like that, you could certainly use analytics to do that in the SQL statement itself (provided you're using an Oracle database). use SUM() over ()...

Sum of Values from previous rows in a dynamic table

Hello,
I have a dynamic table has multiple rows (added dynamically via a button). One column in the table is a Quantity column. Another is a Total column. We do not want to keep a running total, but only wish to display a total when the rest of the cells in that row are emty and the previous row(s) has/have values in the Quantity column. The Total is the sum on the Quatnities up to a blank row. Below is a sample. How do I get teh value of the Quantities in the previous rows?
Quantity
Total
5
8
12
25
7
27
34
22
22
Another option might be to put the Total in the last row with data as opposed to the row below the data.
Any ideas?
Regards,
Karl

SSRS Get value of previous row in a matrix (cannot use previous function because it's a matrix)

I have a SSRS report which uses a matrix for a crosstab effect.
Each row contains about 10 score values in 10 columns respectively. I need each row to check against the previous row, and i need each score value in each column to be compared to the corresponding column score value in the previous row.
If the current score is greater than the corresponding previous score (in the previous row), then i want to change the background of the cell.
if the current score is smaller than the previous, then it's a different color.
if they are equal, or it's the first row in the matrix table, then leave white.
I have found custom code functions to use in the SSRS expression fields, but every single one of them compares against the previous COLUMN value and not the previous ROW value which is what i need. the "Previous" function would be perfect if i
could use it in a matrix but i can't. (i keep getting error "The use of a Previous aggregate function in a tablix cell is not supported"). looking around it turns out that matrices are arrange in groups and not in rows which is why Previous can't
be used and the only way is with custom code.
Please help. if you have any custom code samples that achieve what i need, please share, or give me advice on how to achieve this.
Thank you

I figured it out. Maybe it can help someone else in the future:
Public Shared count as Integer = 0
Public Shared currentRow As Integer = 1
Public Shared MatrixStructures As New System.Collections.Generic.List(Of MatrixStructure)()
Public Shared Function GetCellColor(row as Integer, score as Integer)
If (row > currentRow) Then
count = 0
currentRow = row
End If
count = count + 1
Dim matrixStructure As New MatrixStructure()
matrixStructure.RowIndex = row
matrixStructure.ColumnIndex = count
matrixStructure.ScoreValue = score
MatrixStructures.Add(matrixStructure)
If score = 0 Then
Return "White"
End If
Dim val As MatrixStructure = MatrixStructures.Find(Function(s As MatrixStructure)
Return s.GetRowIndex() = row - 1 AndAlso s.GetColumnIndex() = count
End Function)
If (Not (val Is Nothing)) Then
If val.scoreValue = 0 Then
Return "White"
End If
If score >= val.scoreValue + 2 Then
Return "Green"
ElseIf score <= val.scoreValue - 2 Then
Return "Red"
End If
End If
Return "White"
End Function
Public Class MatrixStructure
Public rowIndex As Integer
Property GetRowIndex() As Integer
Get
Return rowIndex
End Get
Set(ByVal Value As Integer)
rowIndex = Value
End Set
End Property
Public columnIndex As Integer
Property GetColumnIndex() As Integer
Get
Return columnIndex
End Get
Set(ByVal Value As Integer)
columnIndex = Value
End Set
End Property
Public scoreValue As Integer
Property GetScoreValue () As Integer
Get
Return scoreValue
End Get
Set(ByVal Value As Integer)
scoreValue = Value
End Set
End Property
End Class
and to pass the current row number from the expression i use this
Ceiling(RowNumber(NOTHING) / 10)
i divide the row number by 10 because there are ten columns. if you don't know the number of columns, or it's a variable number, then return it from the stored procedure query in the first place. that's what I had to do

SQL Developer - Pulling column value from previous row

I am using Oracle SQL developer and trying to pull a value from a column from the previous row.
Currently this is an example from the code im using.
Select CD1.nbr_dw, CD1.SEQ_DW, CD1.CDL_NET_PAID, CD1.UNITS_ALLOW,CD1.ALLOW_AMT, CD1.UNIT_PRICE, CD1.BACKED_OUT,
case
When CD1.NET_PAID = 0 then 0
****NEW CODE*****
Else CD1.ALLOW_AMT / CD1.UNIT_PRICE
end as NEW_UNITS
From Table_A CD1
join (Select nbr_dw, DET_DW, SEQ_DW
From Table_B
) CD2
on CD1.nbr_dw = CD2.nbr_dw
I need to add another when statement that says when CD1.BACKED_OUT = 'Y' populated the NEW_UNITS field with the previous rows value of CD1.UNIT_PRICE. Note, the CD1.SEQ_DW can be used to determine the previous row. Any ideas?

Hi,
Welcome to the forum!
The analytic LAG function can return a value from the previous row:
LAG (cd1.unit_price) OVER ( -- PARTITION BY x          -- if needed
                               ORDER BY          cd1.seq_dw
                 )It's unclear if you need a PARTITION BY clause or not.
"PARTITION BY x" means that you want the value from the last row that has the same value of x as the current row.
If you omit the PARTITION BY clause, it means you want the last row regardless of what any other columns are.
Whenever you have a problem, it ehlps if you post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
Explain how you get those results from that data.
Always say what version of Oracle you're using.

Expanding table: Calculating difference to value from previous row

Hi there,
I am a complete newbie to LiveCycle Designer (ES2) and have created below document with an expanding table.
Shared Files - Acrobat.com
My aim is to make the form user friendly by adding a calculation in the field "Twist" which calculates the difference from the current row to the previous row.
I have no idea about Java Script, I am afraid, and also don't know if this is possible at all so it's probably a bad idea after all.
The reason for setting it up as an expanding table is so that the form can be used for all 32 instances the form would be used for (they would all require different amount of rows altogether).
The calculation would start in row 2 (Checklist.Table1), take the twist value entered in row 2 and calculate the difference to the twist value entered in row 1.
Then in row 3, it would calculate the difference between twist value in row 3 to row 2 etc.
So subtract value of field in rown with value in rown-1 or something in this direction.
Is there anyone at all who could help me with this at all?
I'd be very grateful for any advice you could give me.
Thanks a lot!
Mathilda

Not sure what happened with the formatting there, try this;
if (Row1.index > 0 && !Row1.resolveNode("NumericField4[0]").isNull)
    var prevTwist = Table1.resolveNode("Row1[" + (Row1.index - 1) + "].NumericField4[0]").rawValue
    var result = Math.abs(3000 / (Row1.resolveNode("NumericField4[0]").rawValue - prevTwist));
   this.rawValue = result;
else
    this.rawValue = "";

Alert based on a value of previous row

Hello there
On a db level there are analytical functions 'LOG' which allows to compare the previous value, but my task is to create the alerter which sends e-mail if next value is greater than current one.
I know that there is a functions previous() etc, but how to implement this, maybe smb can elighten me on this.
Example:
ID      DATE           TRANSACTION COUNT
1     01.01.2014         1120
2     02.01.2014         1099
3     03.01.2014         1700 --> Alert is triggered
SO, for the last value alert has to be triggered and sent to E-mail. On DB level i see no problems implementing this, but how to implement this in Crystal?

One option is to create or get a Crystal User Function Library (UFLs) that provides emailing functionality.
At least one of the 3rd-party UFLs listed here provide such functionality.

Popup need attributes value based on row selected in table

When a row is selected in a table, how can we pass multiple attributes to a pop-up corresponding to that particular row?
Suppose, there is a link in every row of table corresponding to that particular row and when ever a user click to that particular link , a popup should be displayed. Requirement is I want to pass multiple attributes to that pop-up based on the selected row. How is it possible, any suggestions please? Like I want to pass a person location id , person country id, person id and person manager id?
Thanks in Advance...

Hi,
Welcome to OTN. Always mention your JDev version and technologies used (read through this announcement : https://forums.oracle.com/forums/ann.jspa?annID=56)
If your table and popup is on the same jspx page, you can drop the same datacontrol as table (or read-only table) and again drop the same as form (editable / read-only based on your requirement) inside the popup as well.

Getting previous value from previous row

Hi,
My desired output should be
ID     Book_date     Credit     Previous_Credit
123IT1     12/8/2008     100800     72500
from this table:
ID     Book date     Credit
123IT1     12/8/2008     100800
123IT1     12/18/2007     72500
123IT1     11/14/2006     150720
I tried to use the lead function but I'm having problem when I included the date range condtion:
This is my query:
select id, book_date, credit, lead(credit) over (order by rownum) as previous_credit
from t
where book_date between '01-December-2008' and '31-December-2008'
Result
ID     Book_date     Credit     Previous_Credit
123IT1     12/8/2008     100800
The previous_credit column is always blank. I think because of the date range..?
Any idea how to get the right result? pls. help

Your expected output indicates that you may require a LAG

123IT1 08-DEC-08     100800           72500If you always require a Previous Credit then you may want to modify this:
(partition by id order by Book_Date)to this:
(order by id, Book_Date)

Dont show fields with same value as previous row.

? Tsql query to add a sumTotal column from value in current row + value in previous row

--using Sql Server 2008 (Developer)
create table #tmp1(rowID int Identity(1,1), val1 int)
insert into #tmp1(val1)
select 5 union all
select 8 union all
select 12 union all
select 13 union all
select 22 union all
select -7 union all
select 25 union all
select 19 union all
select 32 union all
select -17
What Tsql could produce a result set as follows based on the data from #tmp1?
rowID val1    sumTotal
1          5          5
2          8          13

Analytical function need to work based on previous rows result.

My data are sorted based on sartdatetime column.but i need the sum(value) based on below condition.
Condition :
i need to check with current row with previous rows
if they are same then i need to sum the value with previous row.
else i need to start the summation.
My data like below:
Rownum     Code     Sartdatetime     Value
1     4619     12/9/2012 11:00      219
2     5344     12/9/2012 14:39      27
3     4619     12/9/2012 15:11     20
4     4619     12/9/2012 19:33     14
5     4619     12/9/2012 20:53      16
6     6851     12/9/2012 21:21      1
7     4619     12/9/2012 21:22     35
8     5623     12/10/2012 1:59     4
9     5623     12/10/2012 2:03 3
10     5623     12/10/2012 2:06 5
11     4619     12/10/2012 2:17 1
12     5623     12/10/2012 2:18     5
13     5623     12/10/2012 2:25      2
14     5623     12/10/2012 2:27 2
15     4619     12/10/2012 2:29      30
Eg:
Take the first row. For that no previous rows. So we directly added the value like below.
Rownum     Code     Sartdatetime     Value sum(val)
1     4619     12/9/2012 11:00      219 219
take the seconds row, we can check the code value (5344)with first row value (4619). the values are different . So our summation like.
2     5344     12/9/2012 14:39      27 27
for third row , we can check the code value (4619)with second row value (5344). the values are different . So our summation like.
3     4619     12/9/2012 15:11     20 20
for fourth row we can check the code value (4619)with second row value (4619). the values are same. So our summation like.
4     4619     12/9/2012 19:33     14 34 - The sum of previous row result.
5 th row also same value so
5     4619     12/9/2012 20:53      16 50T he sum of previous row result.
then the same value come again in 7 th row so here we need to start the summation like below.
7     4619     12/9/2012 21:22     35 35.
i want the result like below.
Rownum     Code     Sartdate time     Value Expected result
1     4619     12/9/2012 11:00      219 219
2     5344     12/9/2012 14:39      27 27
3     4619     12/9/2012 15:11     20 20
4     4619     12/9/2012 19:33     14 34

Hi,
Welcome to the forum!
Here's one way to do what you want:
WITH     got_grp_id     AS
     SELECT code, starttime, value
     ,     ROW_NUMBER () OVER ( ORDER BY      starttime )     AS r_num
     ,     ROW_NUMBER () OVER ( ORDER BY      starttime )
           - ROW_NUMBER () OVER ( PARTITION BY code
                                     ORDER BY         starttime
                       )                    AS grp_id
     FROM    table_x
SELECT       r_num
,       code
,       starttime
,       value
,       SUM (value) OVER ( PARTITION BY code, grp_id
                                ORDER BY         starttime
                  )         AS sum_value
FROM      got_grp_id
ORDER BY starttime

ExecuteWithParams - putting attribute values in PageFlowScope?

I've a task flow that includes an ExecuteWithParams method call activity. Things are set up so it will always return no more than 1 row.
What i need to do is put some of the attribute values in the row returned by the ExecuteWithParams in PageFlowScope params, as these values will be used later in the task flow.
is there a way to have an ExecuteWithParams activity set such params based on the returned row? or is there some other way?
I'm using 11g.
Thanks for your help.

Thanks for the response. I tried that, but only a null object results as the return value.
To study what is going on, i defined the pageFlowScope params an object, and then debugged.
Here's the method call activity definition:
<method-call id="ExecuteWithParams">
      <method>#{bindings.ExecuteWithParams.execute}</method>
      <return-value id="__142">#{pageFlowScope.p_ExistingDetailsAttrVals}</return-value>
      <outcome id="__20">
        <fixed-outcome>ExecuteWithParams</fixed-outcome>
      </outcome>
    </method-call>Here's the task flow param definition:
<input-parameter-definition id="__91">
      <name id="__90">p_ExistingDetailsAttrVals</name>
      <value>#{pageFlowScope.p_ExistingDetailsAttrVals}</value>
      <class>java.lang.Object</class>
    </input-parameter-definition>I debugged in a method in a PageFlowScope bean, but this merely returns a null object:
Object o = AdfFacesContext.getCurrentInstance().getPageFlowScope().get("p_ExistingDetailsAttrVals}");I know that the ExecuteWithParams query results are for one row, so this is not due to the query params not resulting in any query results.
So, is there something I'm doing wrong?
Sorry if this seems like a dumb question, but I could not find any significant documentation on ExecuteWithParams - for example, does ExecuteWithParams return anything, or is it merely executing a query a la RowSet.ExecuteQuery(). If it does return, what is the data type? etc.

CreateInsert entering previous values in new rows

hi i have a situation where when i click my createInsert button it make a duplicate values of previous enterd values to new row,for example if i enter values in a row of a table, and if i click createinsert again it take the previous entered values to new row and when i go click save it only save the last entered values,am using a bean and the values am entering using a adftable my createinsert is below am in jdeveloper 11.1.1.6.0,how can i make the new row come with empty values
Edited by: adf0994 on 2012/12/06 4:22 PM

what do you mean i must have the value properties pointing to the attribute in the binding layer,am using a bean
you mean my value should be like this #{bindings.name.inputValue},i don't what that because when i iterator my table am not able to insert value to database,check my post java.lang.RuntimeException: Iterator 'BeanIterator' not found

Error in changing row attribute value

Hi,
I am using JDeveloper 11.1.1.4 and developing a project using ADF-BC.
In my application,I am displaying an adf table from DataControl->view object.
The view object is based on an entity object which has composite primary key [Ex: Name and Rank]
I have an requirement to swap selected row and its previous row's rank values on click of a button.
I have written following code to achieve this.
public void swapRows(ActionEvent actionEvent) {
ViewObject rscMapVo = getRscMapViewObj();
Row currRow = rscMapVo.getCurrentRow(); //------------->Current Row
int currRowIndex = rscMapVo.getRangeIndexOf(currRow);
Row prevRow = getRscMapVoIter().getRowSetIterator().getRowAtRangeIndex(currRowIndex - 1); // ------------> Previous Row
Long currRowRank = ((Number)currRow.getAttribute("Rank")).longValue();
Long prevRowRank = ((Number)prevRow.getAttribute("Rank")).longValue();
//Actual Swapping
prevRow.setAttribute("Rank", new Number(currRowRank));
currRow.setAttribute("Rank", new Number(prevRowRank));
adfFacesContext.addPartialTarget(tblRSCMap);
}//End of method
This is giving me the exception
1)Rank     Too many objects match the primary key oracle.jbo.Key[Group_1 7 ]. [Name is Group_1 and Rank is 7]
2)Rank     Too many objects match the primary key oracle.jbo.Key[Group_1 8 ] .[Name is Group_1 and Rank is 8]
If instead of actual rank values I update it to some random number it updates properly. i.e for example prevRow.setAttribute("Rank", new Number(900)); and currRow.setAttribute("Rank", new Number(800));
The exception occurs when I change one row value with a value that is already present in other row there by giving unique constraint problem.
How to overcome this problem??
Is there any other way of implemeting this solution.
I want the changed attribute values to commit to DB only after final commit but not immediately.
Please advice/suggest.
Thanks,
Praveen

Hi RajGopal,
Even in the model layer it gives the same error.
steps done
1.Create an attribute in entity and set its value
2.Override the method doDML in EntityImpl
protected void doDML(int operation, TransactionEvent e) {
try{
if(this.getTestRank() != null){
this.setRank(this.getTestRank());
}else{
System.out.println("Test rank null");
super.doDML(operation, e);
}catch(Exception excep){
System.out.println("Eceptin in update");
excep.printStackTrace();
Exception
oracle.jbo.TooManyObjectsException: JBO-25013: Too many objects match the primary key oracle.jbo.Key[Group_1 28 ].
