Getting previous value in a cursor

Hi,
Im trying to get the previous row value in PL/SQL.below is a pesudo code of what im trying to achieve , im basically trying to compare the current value of order_id against the immediate previous row value of the order_id . ny ideas nyone?
DECLARE
            CURSOR x
                          SELECT * FROM TABLE X ORDER BY CUST_ID, SHIP_DATE, ORDER_ID,ITEM_ID FOR UPDATE
FOR row IN x
BEGIN
IF(PREVIOUS_VALUE_ORDER_ID = x.ORDER_ID)
THEN..........
[/CODE]

Hi,
Here are three different ideas:
(1) Copy the current row into a local RECORD variable inside the loop.
(2) Do a self-join in the query, so that the cursor itself has the previous and current rows. (If necessary, use the analytic ROW_NUMBER function to number the rows so you can do the self-join correctly.)
(3) Use the analytic LAG function to copy the necesssary columns from the previous row in the query.

TSQL Get Previous values for each group by

Dear Friends,
I have a problem with my TSQL statment.
I need to get previous value for each day and specific unit. Everything goes fine if I have always 2 unit in each day. But if same day has just one unit or less, I cannot have the previous value in the current record.
The Output is this one:
SK_DAY SK_UNIT
VALUE VALUE_PREVIUS_DAY
20131112 2
30.00 NULL
20131112 3
34.00 NULL
20131113 2
40.00 30.00
20131113 3
45.00 34.00
20131114 2
50.00 40.00
I dont have the second record for 2013-11-14, because in this date I just have value for unit 2.
The final output should include the record:
20131114 3
0 45.00
The Statment I have is:
SELECT MAIN.SK_DAY, MAIN.SK_UNIT, SUM(MAIN.VALUE) AS VALUE
SELECT SUM(VND1.VALUE) AS VALUE
FROM FCT_TEST VND1
WHERE CONVERT(DATE,CONVERT(VARCHAR(10),VND1.SK_DAY))>=DATEADD(dd,-1,CONVERT(DATE,CONVERT(VARCHAR(10),MAIN.SK_DAY)))
AND CONVERT(DATE,CONVERT(VARCHAR(10),VND1.SK_DAY))<CONVERT(DATE,CONVERT(VARCHAR(10),MAIN.SK_DAY))
AND VND1.SK_UNIT=MAIN.SK_UNIT
) AS VALUE_PREVIUS_DAY
FROM FCT_TEST MAIN
GROUP BY SK_DAY, MAIN.SK_UNIT
SQL CREATE SCRIPT:
CREATE TABLE [dbo].[FCT_TEST](
[SK_DAY] [int] NOT NULL,
[SK_UNIT] [int] NOT NULL,
[VALUE] [decimal](18, 2) NULL,
CONSTRAINT [PK_FCT_TEST] PRIMARY KEY CLUSTERED

[SK_UNIT] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

Thank you!!!

Thank you Kalman,
But my problem is not with date! Fortunately I have dates for all days.
The problem is for dimension tables like UNITS that I dont have values for all days, and when I try to get the previous value for previous day and each unit I dont have records.

Not getting previous value of List in itemUpdated event receiver

I have scenario that if i update any item in a listA(in sitecollection1) it should update in another listB(sitecollection2)..
I am using beforeproperties it is throwing null value..
but i need that previous value of listA which i have updated just now in "itemupdated" event receiver
here is my code
public override void ItemUpdated(SPItemEventProperties properties)
base.ItemUpdated(properties);
using (SPWeb web = new SPSite("http://natex2:1990/sites/ess/facilities/spaces").OpenWeb())
web.AllowUnsafeUpdates = true;
SPList list = web.Lists.TryGetList("LocationDetails");
//string querry = properties.ListItem["Title"].ToString();
string querry = properties.BeforeProperties["Title"].ToString();
SPQuery qury = new SPQuery();
qury.Query = "<Where><Eq>" +
"<FieldRef Name='Title' />" +
"<Value Type='Text'>" + querry + "</Value>" +
"</Eq>" +
"</Where>";
SPListItemCollection coll = list.GetItems(qury);
foreach (SPListItem item in coll)
string data = properties.AfterProperties["Title"].ToString();
item["Title"] = data;
list.Update();
web.AllowUnsafeUpdates = false;
please anybody help me i need urgent help

Are you working with a list or a library? In a list, you will need to handle the synchronous (ItemUpdating) event instead of the asynchronous (ItemUpdated) event in order to access the original value...but there's a catch!
As per the table in
this post, the BeforeProperties hashtable is not populated for list items. You can, however, access the original value using
properties.ListItem (the line you have commented out above) in the
ItemUpdating event.
Confusing, I know...but hopefully that helps!

This is my query:
select id, book_date, credit, lead(credit) over (order by rownum) as previous_credit

where book_date between '01-December-2008' and '31-December-2008'

How to find previous and next value of a cursor?

Im trying to do an update to a table.
I have a set of rows fetched in a cursor. Now i loop through the cursor and update a field in the table.
for certain condition alone i need to fetch the previous value in the cursor and update the table with that.
can anyone let me know if i can fetch the previous and next value of a cursor for this DML operation?
Thanks in advance.

You can do it via PL/SQL routine.

How can I get the value of the previous item

Hi,
I have a block with some records in it.
I want to capture the value of the previous item of the cursor position
for eg I have emp_no, and emp_name
If I click emp_name it goes to different block ang brings up emp info. for that particular employee. but to get that I need emp_no
I'm taking emp_name by giving
emp_name := system.cursor_value
how can I capture emp_no value
Thanks in advance

Hello,
try this:
name := :blk.emp_name ;

How to get a value from the previous element (XSLT/XPATH gurus ahoy!)

Hi All,
I am building an RTF template for a "letter of reference"-report. Sometimes there are several rows in the data, that need to be printed as one. This is due to consecutive temporary contracts, which will be printed out as one period of service.
Here's a simplified data example to illustrate the problem.
<ROW>
<START_DATE>01-01-1980</START_DATE>
<END_DATE>01-01-1988</END_DATE>
</ROW>
<ROW>
<START_DATE>01-01-1988</START_DATE>
<END_DATE>01-01-1990</END_DATE>
</ROW>
<ROW>
<START_DATE>01-01-2000</START_DATE>
<END_DATE>01-01-2005</END_DATE>
</ROW>
With the data above, I should print two lines:
01-01-1980 - 01-01-1990
01-01-2000 - 01-01-2005
I need to compare START_DATE of an element (except for the first one) with the END_DATE of the previous element, to find out whether to print the END_DATE for that element or not. How can I get that value from the previous element?
Thanks & Regards, Matilda

use this to get the following End_date
<?following-sibling::../END_DATE?>
Try this
<?for-each:/ROOT/ROW?>
==================
Current StartDate <?START_DATE?>
Current End Date <?END_DATE?>
Next Start Date <?following-sibling::ROW/END_DATE?>
Previous End Date <?preceding-sibling::ROW[1]/END_DATE?>
================
<?end for-each?>
o/p
==================
Current StartDate 01-01-1980
Current End Date 01-01-1988
Next Start Date 01-01-1990
Previous End Date
================
==================
Current StartDate 01-01-1988

How to get a summ of all previous values

Hello ALL,
Could you please give an advice on how to find the sums of all previous values in 1 select without using dynamic sql. Cross join is not a variant because of a huge response time.
OR may be there are any other ideas on how to find first rows with total sum equals to some general value? My idea is to find a sum of all preceding values and the first of such sums that would be equal to the general value or greater it is a necessary result.
For example we have goods receipts:
MATERIAL | BATCH | QTY
material1 batch1 1
material1 batch2 2
material1 batch3 3
material1 batch4 4
material1 batch5 5
material1 batch6 6
and general qty is 7 - it's our current stock. So I should take material from [batch1 to batch4] to get necessary QTY >=7 (1+2+3+4=10>7) So our current stock consists of batch1,batch2,batch3 and remains of batch4.
Thanks in advance!

UDF: how to get a value in the previous record when lopping over records?

Hello
I have this challenge:
Source message:
<row>
<ID>111</ID>
<Score>200</Score>
<Date>2010-01-01</Date>
</row>
<row>
<ID>111</ID>
<Score>230</Score>
<Date>2010-01-02</Date>
</row>
<row>
<ID>112</ID>
<Score>230</Score>
<Date>2010-01-03</Date>
</row>
etc...
Now the case is, that IF the value of ID of the current record (row) is equal to the value of the ID of the previous record AND the Score value of the current record is bigger than the Score value of the previous record THEN a record in the target message must be created with these values:
Target Message:
<row>
<ID_target> value of source ID </ID_target>
<Score_yesterday> Score value of previous record (day) </Score_yesterday>
<Score_current_date> Score value of current record </Score_current_date>
<Date_current> Date of current record </Date_current>
</row>
I am thinking of using GlobalContainer to store the previous values but am note sure how to maintain these previous values. In addition, I am thinking about using a UDF on the target row record, which will just create the row, if conditions are met (result.addValue("");) and then just make a simple mapping of the ID_target, Score_current_date and Date_current fields and make an other UDF for the Score_yesterday field where I get the Score for the previous record using the GlobalContainer value, that I stored in the other UDF.
BUT:
Should I use "All values of context" or "All values of Queues" in the UDF used on the row record and how do I make sure, that the Score_yesterday global container value is maintained correctly? I am planning of setting it in the UDF used on the Target row record but will it then be in sync with the consuming UDF of the Score_yesterday field?
Java code to go into the UDF would be very much appreciated

Hyperion Finance Reports - Get previous Column value using cell function

Hi Guys,
In Hyperion Financial Reports, i am trying to get the value of the previous column.
I have tried hard coding the reference of the previous column by putting Col[B] as a cell formula.
But i need to achieve it using dynamic formula for example
Cell(Current Row, Current Column -1)
The above explanation is syntactically incorrect, i am looking out for the correct syntax which helps me get the value of the previous column.
Thanks in advance.

What are you trying to achieve? Maybe there are different ways to look at it.
There is no function (that i'm aware of) which performs a previous column display. Why you do think that [B] when you are in C is not working?
Have you looked at the example given in Current/Cur Keyword
Regards

How to get the previous value of a field before saving the record

Hi All,
I have a requirement like, listing out the modified field values with their previous value and new value using integration events or any method.
For Ex: If i modify the customer name from "Jack" to "Amith" in the record.
Then i have a requirement to display the message like : CustomerName has changed from "Jack" to "Amith"
Please post your help notes on this.It's Urgent.
Thanks & Regards
Amith

Hello Amith,
How does a user perform the modification? Do you already have access to the existing value when the user makes the update? How are you identifying the record to be updated within CRMOD and what method are you using to perform the update?
Thanks,
Sean

How to use Ajax Get Multiple Values in Tabular form?

Hi All-

2. Create two application items - TEMPORARY_APPLICATION_ITEM2, T_ROWNUM2
3. Put the following in the Page Header:
<script language="JavaScript" type="text/javascript">
function f_set_multi_items_tabular2(pValue, pRow){
    var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=Set_Multi_Items_Tabular2',0);
if(pValue){
get.add('TEMPORARY_APPLICATION_ITEM2',pValue)
get.add('T_ROWNUM2',pRow)
}else{
get.add('TEMPORARY_APPLICATION_ITEM2','null')
    gReturn = get.get('XML');
    if(gReturn){
        var l_Count = gReturn.getElementsByTagName("item").length;
        for(var i = 0;i<l_Count;i++){
            var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
            var l_ID = l_Opt_Xml.getAttribute('id');
            var l_El = html_GetElement(l_ID);
            if(l_Opt_Xml.firstChild){
                var l_Value = l_Opt_Xml.firstChild.nodeValue;
            }else{
                var l_Value = '';
            if(l_El){
                if(l_El.tagName == 'INPUT'){
                    l_El.value = l_Value;
                }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
                    l_El.parentNode.innerHTML = l_Value;
                    l_El.parentNode.id = l_ID;
                }else{
                    l_El.innerHTML = l_Value;
    get = null;
</script>
Add the follwing to the end of the above JavaScript:
<script language="JavaScript" type="text/javascript">
function setLOV(filter, list2)
var s = filter.id;
var item = s.substring(3,8);
var field2 = list2 + item;
f_set_multi_items_tabular2(filter, field2);
4. Tabular form query:
select
"BOOK_ID",
"BOOK",
"SUBJECT",
"PRICE",
"AUTHOR",
"QTY",
"BOOK_ID" BOOK_ID_DISPLAY
from "#OWNER#"."MY_BOOK_STORE"
5. In Book_ID_DISPLAY column attribute:
Add the following code to element attributes: onchange="javascript:f_set_multi_items_tabular2(this.value,'#ROWNUM#');"
Changed to -> onchange="javascript:setLOV(this,'f03');"
Now, T_ROWNUM2 returns value as f03_0001. But, TEMPORARY_APPLICATION_ITEM2 returns as [object HTMLSelectElement]...
Please help me to see how I can populate the data with this tabular form format. Thanks a lot in advanced!!!

Updated code in Red..

Lets start with looking at what the javascript code is doing.
function f_set_multi_items_tabular(pValue, pRow){
/*This will initiate the url for the demand process to run*/
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
                          'APPLICATION_PROCESS=Set_Multi_Items_Tabular',0);
if(pValue){
    /*If there is an value than submit item name with value*/
    get.add('TEMPORARY_APPLICATION_ITEM',pValue)
    get.add('T_ROWNUM',pRow)
}else{
    /*Else set the item TEMPORARY_APPLICATION_ITEM to null*/
    get.add('TEMPORARY_APPLICATION_ITEM','null')
/*Submit the url and te returned document is of type XML*/
gReturn = get.get('XML');
if(gReturn){
    /*There is something returned*/
    var l_Count = gReturn.getElementsByTagName("item").length;
    /*For all elements of the tag item*/
    for(var i = 0;i<l_Count;i++){
      /*Get the item out of the XML*/
      var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
      /*Get the id of the item*/
      var l_ID = l_Opt_Xml.getAttribute('id');
      /*Get the element in the original page with the same id as
      **the item we have in the XML produced by the ondemand process
      var l_El = html_GetElement(l_ID);
      /*Now get the value of the item form the XML*/
      if(l_Opt_Xml.firstChild){
        var l_Value = l_Opt_Xml.firstChild.nodeValue;
      }else{
        /*There is no value*/
        var l_Value = '';
      if(l_El){
        /*There is an element with the same id as the item we are processing*/
        if(l_El.tagName == 'INPUT'){
          /*The element is an input item just set the value*/
          l_El.value = l_Value;
        }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
          /*If it is a span elment and has the class grabber
          **Then set the innerHTML of the parent to the value
          **and the id of the parent to the id
          l_El.parentNode.innerHTML = l_Value;
          l_El.parentNode.id = l_ID;
        }else{
          /*Else set the value as innerHTML*/
          l_El.innerHTML = l_Value;
get = null;
Now where it went wrong in your initial post
The XML that was returned by your XML process would be something like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_1">CSS Mastery</item>
<item id="f03_1">22</item>
<item id="f04_1">Andy Budd</item>
<item id="f05_1">1</item>
</body>
When you don't use apex_item to create your tabular form a item in the table will look like
<input id="f02_0001" type="text" value="CSS Mastery" maxlength="2000" size="16" name="f05" autocomplete="off">
Notice the id's f02_1 and f02_0001 don't match.
So to make it work the XML would have to look like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_0001">CSS Mastery</item>
<item id="f03_0001">22</item>
<item id="f04_0001">Andy Budd</item>
<item id="f05_0001">1</item>
</body>
To do that simply use lpad in the ondemand process like
HTP.prn ('<item id="f02_' || lpad(:t_rownum,4,'0') || '">' || v_subject || '</item>');
HTP.prn ('<item id="f03_' || lpad(:t_rownum,4,'0') || '">' || v_price || '</item>');
HTP.prn ('<item id="f04_' || lpad(:t_rownum,4,'0') || '">' || v_author || '</item>');
HTP.prn ('<item id="f05_' || lpad(:t_rownum,4,'0') || '">' || v_qty || '</item>');
Keep in mind that the above is based on your original post and #ROWNUM# not being lpadded with zero's.
