How to compare 2 timestamp value (in terms of minutes)

Hi all.
I've got 2 timestamp value a,b. I would like to count the different (in terms of minutes).
I tried a.compareTo(b), but it's not work.
pls help.
Thanks
Regards,
Kin

I assume by "timestamp value" you mean Dates or longs.
Ever thought of basic maths?
date a - date b? Dates can be expressed in longs, as you might know.

How to compare the value of a specied attribute to a string

I am looking for an example of how to compare the value of an attribute to a string. (I think)
I have been trying to:
if (attrs.get("title")== "Vampire") -- you already know this did not work.
How can I check to see if the title="Vampire"?
The code below will get me the title of admin (which should be Vampire)

I guess, you are looking for searching for attributes of an user object.
Here is the sample code to list all the attributes of an 'user' objectclass.
Tell me if it helps or not.
import java.util.Hashtable;

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.

How to compare single value with multiple values

In my query I have something like this:
A.SOR_CD=B.SOR_CODE where A and B are 2 different tables. This condition is in the where clause. The column in table A has single values but some values in table B have multiple comma separated values (822, 869, 811, ..). I want to match this single
value on the left side with each of the comma separated values. Please let me know how will I be able to do it. The number of comma separated values on the right side may vary.

Hi MadRad123,
According to your description, you want to compare single value with multiple values in your query. Right?
In this scenario, the table B has comma separated values, however those comma separated values are concatenated into a string. So we can use charindex() function to return the index of the table A value. And use this index as condition in
your where clause. See the sample below:
CREATE TABLE #temp1(
ID nvarchar(50),
Name nvarchar(50))
INSERT INTO #temp1 VALUES
('1','A'),
('2','A'),
('3','A'),
('4','A'),
('5','A')
CREATE TABLE #temp2(
ID nvarchar(50),
Name nvarchar(50))
INSERT INTO #temp2 VALUES
('1','a,A'),
('2','A,B'),
('3','c'),
('4','A,C'),
('5','d')
select * from #temp1 a inner join #temp2 b on a.ID=b.ID
where CHARINDEX(a.Name,b.Name)>0
The result looks like below:
Reference:
CHARINDEX (Transact-SQL)
If you have any question, please feel free to ask.

How to compare the value of a cell before changing and after changing.

Hey there,
Now I want to implement a JTable. And the requirement is that users can edit a cell in the Table only once. I think there are two possible ways. One is that after user edited a cell, I will set this cell read only. Another way is to compare the vaule before and after the changing. If it is different, then write back the previous value.
But I did not know how to implement in Java. Can anybody help me?
Thanks alot!
Shelly

inevitably, you will have to save a before copy of
the data, what this many times amounts to is that you
will need to have 2 identical data structures before
you start or some type of locking mechanism for each
piece of data.Why is this inevitable? I don't see it as inevitable at all. In fact, it's quite simple to implement a TableModel that returns false when isEditable(int, int) is invoked for any cell that has already had setValueAt(Object, int, int) inovked on it, for example. Depending on the requirements and implementation a different methodology may be needed for determining when the edit has taken place, such as a custom editor that notifies the TableModel when stopCellEditing() is invoked. Heck, overriding editingStopped() in JTable to do it might even work.
So, create a TableModel that returns isEditabe(int, int) as true only if the cell hasn't been edited yet. The only problem to solve from there is how you know when it's been edited. I've already given you a few leads on that, it's not particularly hard but depending on your exact implementation it may require different solutions.

How to compare 3 values in array

Hi all
This is my first post so please be tolerant
I need to find "bad values" in array, it will be easier to explain it using example so:
I have array like this: 0 0 0 0 0 0 0 0 5 0 0 0 0 <- so "5" is the bad value, my method is to check two of nearby values so x(i-1) = 0, x(i)=5 x(i+1)=0, and if checked value is more than 25% bigger or smaller it should be replaced by average of neighborhood.
next example: 0 1 2 3 4 9 6 7 8 <- bad value is 9, and result of my filter should be (4+6)/2 = 5
I've done it using formula node (not 20% and not average, but the point is the same) and it's working but now I want to do it without C and I had lots of problems with memory cause the size of array is 10000.
I attached vi and signal thah you can check that it's working fine
Thanks
Mike

Shouldn't e.g. the value 4 be outside too, because the average of 3 and 9 (=5.5) is more that 25% different to 4?
Here is a quick draft comparing three versions (LabVIEW 8.2):
Your formula node version
the same algorithm in G
Something along the lines you are proposing here.
As you can see, the new idea is not quite satisfactory. It needs more thought. Still, these drafts should give you some ideas how to do it. Modify as needed.
Also your data is similar to a square wave and has these large step functions where the value changes dramatically. These should probably be ignored. Maybe you should look at the first derivative and replace parts where a large positive slope is immediately followed by a negative slope of similar size, for example.
You should also look at absolute steps instead of percentages. If you use percentages and the value is zero, everything is outside, because even 5000% of zero is still zero, right?

How to compare the values of 2 select queires in two diff DB's

Hi,
I need help in building the logic to achieve this :
A program is needed to get reference data from ABC database in ORACLE and update our reference tables with any changes in DEF database in SYBASE.
Pls give me an example where i can compare the select queires from different databases one exsiting in oracle and one in sybase .
Any help will appreciated.
Thanks

PLS HELP.
I have no idea on how to do
2) Using your specific requirements, determine how to know if there is a "new row" or a "missing row" or a row , which has a different description
Say Table A in oracle looks like this
Sno Description
1 Out Of Order
2 Shipped
3 Back Order
Say Table B in Sybase looks like this
Type Text
1 Out/Order
2 Shipped
4 Not manufactured
I have to see to that the rows present in Table A in oracle , should be same as rows in Table B in sybase
If not , we have to update , insert and delete the row which is not present in Table A in oracle in Table B in sybase.
In the table example i gave , In the first row of Table B in Sybase , the Text is different from that of Description in Table A for that Sno "1"
So we should update the description.
Row 4 has Sno "4" which is not their in table A , so delete that row from table A.
And In table A , Sno "3" row exists , so we should insert that record in table B.
I know how to query the tables , and get the rows into Result Set ..after that how can i compare and take the steps to update , insert and delete?

How to compare date values in XQuery

begin
select sysdate into x_date from dual;
select xmlquery( '<A>
{ [b]for $a in ora:view("TableA")
let $id = $a/ROW/ID/text()
where $a/ROW/TRANS_DATE >= x_date
return ..
</A>' returning content}
into temp from dual;
end;
This gives me invalid variable name. I hard code the date and it works fine. I tried xs:date also. Please help.

You could use the XQuery function fn:current-dateTime iso trying to use a parameter.
If you want to use an parameter with XQuery, they need to be nodes (not just atomic values) and have to passed using the passing clause.
See the oracle doc for details and examples.

How to compare pixel values of two different grayscale images...

I have two different grayscale images both of much different sizes. One is 46x20 pixels and the other is 2592x1944 pixels. I'm having trouble finding a way to "scan" the smaller image through the larger one so that comparisons between the pixel values can be made. Basically I'm trying to see if anything matches the smaller image in the big image semi-closely. I can access the pixel values of each image but I can't figure out an algorithm to perform the scan. Any help at all would be very much appreciated! Thanks.

Hi
recipe:
1.
Find all the values for all the pixels in the small image. Some might be similar. Put all those values that are useful into a List called comparisonList.
2.
For each scanline in the large image
For each pixel in the scanline
is this pixel the same value as a pixel in the comparisonList?
if so do something
is the scanline finished?
if not next pixel
loop to next scanline
where scanline is a horizontal line in the big picture.
my 2c
hope helps
