How to compare, current value in :block.text_item with the database value

Hi
Could you please tell me
How to compare the current value in :block.text_item with the corresponding database column value.
I am using forms 10g
There is block and there is an text Item in that block.
When I run the form and query the block (tabular), the :block.text_item shows me, whatever value there in the database.
Now I add some value in the :block.text_item to the existing value.
now
the :block.text_item contains old+ new added value
whereas
the database table contains 'old' value
Now on a button click , I want to find out what is the value that I have added
Could you please tell me, is it possible without writing a select query?

Hello,
Now on a button click , I want to find out what is the value that I have addedSo you mean always user will add value in the existing value. Because this way will fail in one case. Let say
Value in Database is = ABCD
User opened the form and he removed the D and write E and now value is ABCE and length is still same 4. So, there is no addition.
Anyway you can know the database value at runtime there is one property for item called DATABASE_VALUE. It gives the value which is in database while you are running the form before save. and you can use like this..
Trigger = WHEN-MOUSE-DOUBLE-CLICK on item level
DECLARE
vItemValue DATATYPE; -- Set the data type according to your desired field.
vValueAdded DATATYPE; -- Set the data type according to your desired field.
BEGIN
vItemValue:=GET_ITEM_PROPERTY('ITEM_NAME',DATABASE_VALUE); -- It will return you the database value in vItemValue variable.
IF LENGTH(vItemValue)>LENGTH(:FORM_ITEM_NAME) THEN -- It mean something change or added
vValueAdded:=SUBSTR(:FORM_ITEM_NAME,LENGTH(vItemValue)+1);
MESSAGE('Added value is : '||vValueAdded); -- It will show you the added value.
END IF;
-- now suppose you want to show the old and new value in message not the added one
-- Then no need of IF condition. You can just use message like this
-- And i would prefer to use like this way
MESSAGE('Old Value : '||vItemValue||' New Value - '||:FORM_ITEM_NAME);
MESSAGE('Old Value : '||vItemValue||' New Value - '||:FORM_ITEM_NAME);
END;Hope it is clear.

Compare current date with dat from db by JSTL

hi all
I use
<tr><c:forEach items="${allFound}" var="found" varStatus="myRow">
<td><c:out value="${found.submitDate}"/></td>
</tr>
</c:forEach>
to past some value out of db
how can I compare this submitDate with Current Date by JSTL
Thank you!

Whether or not you can compare it depends on what the type of "${found.submitDate} is coming from the Database.
I am going to presume it is a java.util.Date.
You can get the current date like this
<jsp:useBean id="now" class="java.util.Date"/>
You can then compare them using an EL expression:
{code}
<c:if test="${submitDate < now}">
We have not yet reached the submit date.
</c:if>{code}
EL uses the java compareTo methods, so both of your objects +must+ be of the same class in order for this comparision to work.
If you get back a String from the database, you would have to use <fmt:parseDate> to get a java date.
If you get back a java.sql.Date from the database, it would get trickier. The hack would be to go java.sql.Date -> String -> java.util.Date using <fmt:formatDate> and <fmt:parseDate>
Hope this helps,

How to compare current time with any particular time?

Hi All,
Problem:
I have a form which accept data from user but i want that user can enter data only before 4 in the evening after that no data will be accepted and user get any message. Now the problem is I want to compare the current time with 4 o clock or 16:00:00 but i dont know how to check whether the current time is greater or lesser than 4. Till now my code are like this: if(tt.equals("16:00:00")){}else{}
where tt is current time. but this is not the feasible solution for my second clause.
Any kind of help will greatly appreciate.
Thanks

One more thing:
I find timestamp class quite helpful in my case but i
dont know how to implement the before() method
of this class.
Any idea.* You wouldn't implement before(). You'd just use it. It's already implemented for you.
* before() doesn't just compare the hour of the day. It compare two date & time objects to see which one is greater--that is, it effectively looks at all the fields, not just HOUR.
* You don't need Timestamp if you're not dealing with a database.

Grand Total 12000 9000 90
Here we are using Column selector for Date column to change the report from Date to Week (or) Month (or) Quarter (or) Year.
My Questions
1. I want to compare Default Date report with Perious Date, Last month Date and Last Year Date.
2. If I select Month from Column Selector then I want to compare Month report with Last Month, Last year Month or Perious of Last year month.
3. If I select Year from Column Selector then I want to compare Year report with Last year, or Perious of Last year and so on.
Please help me, how can we achive the above task.
Thanks in Advance.

Hello,
First you have to define the new measures for last month, last year and so on. You can refer to this link:
http://www.rittmanmead.com/2007/04/obi-ee-time-dimensions-and-time-series-calculations/
After that, what you can do is instead of using a "Column Selector" you should use "View Selector". You can create different views, one for month, other for Year and include them into a "View Selector".
After that you can add it in "Compound Layout".

SSRS Variance expression problem. Create a Variance expression. Compare current month with same month from previous year.

Hello,
I am using VS2010 shell. I have a matrix report where I have a row group by Year. Then I have a column group by Month.
When I run the report, I get 2013 data on top of 2014 data. Now I need to create a variance by year for each month.
So in the example below, I need to create an expression that will pull the variance for Oct 01... subtracting 2013 from 2014 for the months. So I need to Subtract 8,222 - 4290. I have no clue.
Here is what my rdl looks like.
Thank you for your help.

Hi Adrian,
If I understand correctly, you want to calculate the difference order between 2013 and 2014 for every month. And there are only two years in the FISCAL_YEAR field.
If in this scenario, we can simply use the following expression to achieve your requirement:
=first(Fields!ORDER.Value)-last(Fields!ORDER.Value)
The following screenshot is for your reference:
If there are any misunderstanding, please elaborate the issue for further investigation.

Compare month sales with previous year same month sales

hi all.
we need to compare given month of this year with same month of last year. we need to compare sales quantity and value.
the query is on 0RT_C40 multiprovider. We have tried all options using 0Calmon, calday, fiscal year... but whenever we specify offset, we are not getting data. there is valid data for previous year.
plz let us know what else to do? check with 0RT_C40.
thanks in advance.
regards: gaurave

Gaurave,
Are you selecting the time period in a selection in columns or rows, or are you selecting the time period in the Filter or Free Characteristic area.
When you make the initial selection of say Period 11.2007 in the Free Characteristic area, and then within a selection but on an offset to derive 11.2006, the fact that you have made your selection of 11.2007 in the Free Char area will restrict the entire query results to this time period.
Both your picks on time should be in selections in the Columns or the Rows.

FULL JOIN Sales2014 t2
On t2.Company = t1.Company
2.
SELECT Company,
MAX(CASE WHEN YearVal = 2015 THEN Sales ELSE 0 END) AS CurrentYearSales,
MAX(CASE WHEN YearVal = 2014 THEN Sales ELSE 0 END) AS PriorYearSales
FROM
SELECT Company,Sales2015 AS Sales,2015 AS YearVal

Compare the current value with the previous value in the same column

Hi all,
I have to include a statement in a query which allows to compare the current value of column A with the previous value of column A (same column). from there, I need to add a condition in order to have the expected result.
Let's take an example to illustrate what I want to achieve:
I have the following columns in table called 'Charges':
Ship_id batch_nr Order_nr Price
SID1111 9997 MD5551 50
SID1111 9998 MD5552 50
SID1111 9999 MD5553 50
SID2222 8887 MD6661 80
SID2222 8887 MD6662 80
SID2222 8887 MD6662 80
SID3333 6666 MD7771 90
I want to check if the ship_id of row 2,3 (and more if available) is equal to the ship_id of row 1.
If it is the case, then value 'together with the first batch_nr' in row 2 and 3 under Price column. If not, then keep the original value of Price column
PLease see below the expected result:
Ship_id batch_nr Order_nr Price
SID1111 9997 MD5551 50
SID1111 9998 MD5552 together with 9997
SID1111 9999 MD5553 together with 9997
SID2222 8887 MD6661 80
SID2222 8887 MD6662 together with 8887
SID2222 8887 MD6663 together with 8887
SID3333 6666 MD7771 90
Thanks in advance for your help, it is really urgent.

]That looks like the query you were using before you started this thread.
Modify it, using the analytic fucntions FIRST_VALUE and LAG, like I showed you.
I see that you did simplify the problem quite a bit, and it's good that you did that.
It doesn't matter that your real problem involves joins or GROUP BY. Analytic functions are calculated on the results after all joins and GROUPS BYs are done. Just substitute your real expressions for the simplified ones.
For example, in your simplified problem, there was a column called order_nr, but I see now that's it's really called o.ordnum. Where the solution I posted earlier says "ORDER BY order_nr", you should say "ORDER BY o.ordnum".
Here's a less obvious example: in your simplifed problem, there was a column called price, but I see now that it's really SUM (tc1.chrg_amt + tc2.chrg_amt + tc3.chrg_amt). Where the solution I posted earlier says "TO_CHAR (price)", you should say "TO_CHAR (SUM (tc1.chrg_amt + tc2.chrg_amt + tc3.chrg_amt))". (You can't use an alias, like "Total Price", in the same SELECT clasue where it is defined.)
I removed some columns from the select as they are not relevant for the wanted action like 'adress details or other references'.
Now here is the result:
Shipment ID     Order Number     WMS Batch     Freight      Fuel Price Order Total Price
SID0132408     MDK-000014-05602649     04641401     110     10 120
SID0132408     MDK-000014-05602651     04641402     110     10 120
SID0132408     MDK-000014-05602652     04641363     110     10 120
as you can see, the 3 orders have the same shipment ID.
The expected result should be shown under column 'Total Price' as follows:
Shipment ID     Order Number     WMS Batch     Freight      Fuel Price Order Total Price
SID0132408     MDK-000014-05602649     04641401     110     10 120
SID0132408     MDK-000014-05602651     04641402     110     10 tog with 04641401
SID0132408     MDK-000014-05602652     04641363     110     10 tog with 04641401Okay, so those are the correct results that I asked for, plus the incorrect results you're getting now. Thanks; extra information doesn't hurt.
But where is the raw data that you're starting with?
It looks like you tried to format the code (but not the results) by typing this 1 character:
before the formatted section and this different character
after the formatted section. To post formatted text on this site, type these 6 characters
before the formatted section, and the exact same 6 characters again after the formatted section.

Comparing the current value with the previous one in Powershell

Hi,
New to scripting and i was wondering how can I compare the current value with the previous value?
I am having trouble with the loop structure, and I am not sure I am on the right track...
I am trying to compare the record to next record in the same csv file after import-csv... My code runs fine, but is not giving the right result.
$FilePath = Get-FileName -initialDirectory "C:\"
#Testing for null
If($FilePath)
$Data = Import-csv -Path $FilePath | Sort-Object BUYER, {[int] $_.PO_NBR}, {[int] $_.LINE_NBR}
Foreach($fData in $Data)
$i = $fData
Foreach($i in $fData)
if($fData.Buyer -eq $i.Buyer)
#save all the same buyer name to a new variable
Write-Host "Same as previous"
Else
Write-Host "Variable is null"
Remove-Item function:\Get-FileName

Thank you. The Foreach loop is now working properly.
Can I ask what is the purpose of "-ea 0" in the import-csv? I can't seem to find "-ea" as a parameter for import-csv in help.
-ea is short for -ErrorAction.

Compare few columns current value with previous version within a table

I have a table that stores version information. Everytime there is a change in one field, a new version is created. I need to get the last value and the current value (after the update). There might be around 12 columns that I need to check for any updates.
How may I achieve this?
Any help greatly appreciated.
Thx!

Perhaps you're looking for something like
SELECT col1, col2, col3, ... colN
FROM (
    SELECT col1, col2, col3, ... , colN, RANK() OVER (ORDER BY update_date DESC) rnk
      FROM your_table
WHERE rnk <= 2It would be very helpful in general, if you could provide DDL
SCOTT @ jcave102 Local> create table a (
2 version number,
3 create_time timestamp,
4 col1 number,
5 col2 number,
6 col3 number
7 );
Table created.

1 select version, col1, col2, col3
2 from( select version, col1, col2, col3, rank() over (order by create_time desc) rnk
3          from a )

How can I structure the statement to get (the most recent - order by date ) result for Comp?

Satheesh Variath, I just had to make some corrections from your script to get the correct answer:
CREATE
VIEW vw_Comp
AS
SELECT
TOP 1 t.IDNO,t.name,t.[Date],t.Price1,t.Price2,
CASE
WHEN t.Price2
> LAG(Price2,1)
OVER (PARTITION
BY name
ORDER BY IDNO)
THEN 1
WHEN t.Price2
< LAG(Price2,1)
OVER (PARTITION
BY name
ORDER BY IDNo)
THEN -1
ELSE 0
END
AS Comp
FROM
@T t
ORDER
BY DATE
DESC
The adjustments: the selection of the most recent comparison (Top 1) and the use of the function LAG (instead of LEAD) to get the previous value of the column.

Compare current value with previous value
