Comparing two numbers with different formats

Dear Java developers
I am trying to compare two numbers but they have different formats. long x = 8981261369, Object obj = "8,981,261,369".
I am trying to see if this two values are equal which is the case in the example above except one has a thousand separator but not sure how to do that.
How can I lose the thousand separator and just compare them as two long values.
Your input will be much appreciated
Thanks

I need a generic way of doing this. Because sometimes the Object does not have a thousand separator. Can i use some kind of NumberFormat to do this.You'll need to know what formats the string (not the number--as already mentioned, numbers don't have formats) can have, and then try them one by one.
Of course, there can be some ambiguity. Does "123,456" represent one hundred twenty three thousand four hundred fifty six, or is that comma a decimal separator, and it represents one hundred twenty three and four hundred fifty six thousandths?
The point is, you have to have a clear definition of what formats are allowed and how to determine which one it is. There's no magic way for Java to do that for you.

Compare two dates in different format.

Hi
I want to compare two dates....one of which is in the timeStamp format ("yyyy-MM-dd HH:mm:ss")
and the other is in java.util.Date i.e Tue Oct 11 10:22:47 GMT+05:30 2005
Do I have to tokenise and then compare them.Is there any better approach?
I want to find out which is greater/smaller one.
Pls help.
Regards,
Sandip.

I would convert both to Date and compare them. To convert String to Date check java.text.SimpleDateFormat and its parse(...) method.

Compare two dateTime with different timezone

HI, All,
I found a strange thing when compare two dateTime in BPEL;
In my BPEL process, client passed a date time to the process , and the process compare the date time with current data time.
1.client pass cutoffDate to process
2. in a switch activity, I compare cutoffDate with current date. code:
bpws:getVariableData('cutoffDate')<=xpath20:add-dayTimeDuration-to-dateTime()
but seems this compare ignored the timezone information.
For example:
cutoffDate=2010-03-05T06:17:38.838+00:00
currentDate=2010-03-05T14:10:38.838+08:00 this time =2010-03-05T06:10:38.838+00:00
but cutoffDate<currentDate == true... seems it ignored the timezone info..
This is a bug or I used a wrong compare function?
Thanks.

Hi Colin,
Please go through below link, there is topic about calculating difference between dates. Hope you find solution.

Trying to compare date columns with differing formats...

I have an app that created a series of tables via ODBC using ANSI standard datatypes. For most, this isn't a problem, but one in particular is driving me crazy: TIMESTAMP. In Oracle, it shows up as a TIMESTAMP(6). I don't want to mess with the app's tables, so every time there is an insert to their tables, I have a trigger which creates records in corresponding tables I build using standard Oracle datatypes (DATE).
I have one function that gets called by several of the triggers that retrieves me a specific row to update, and it uses the value from this TIMESTAMP field in the WHERE clause like this (the value is passed into the function as a parmeter):
SELECT TIMECARD_ID INTO tc_id FROM TS_TIMECARD_MAIN
WHERE EMP_ID = e_id AND VEHICLE_ID = v_id
AND IN_TIME <= logout AND OUT_TIME IS NULL; <----
I seem to have a formatting issue, because unless the "logout" date is a full day later than IN_TIME, it doesn't pull the record (my code does a check to verify there is only one record matching the criteria but I haven't posted it all here for simplicity). I need it to be able to select the correct record with a one second difference.
I have NLS_TIMESTAMP_FORMAT set to 'YYYY-MM-DD HH24.MI.SS.FF' and NLS_DATE_FORMAT set to 'YYYY-MM-DD HH24:MI:SS'. The relevant describes are included below. Can anyone suggest how to format my query (I expect to use the TO_DATE and TO_CHAR to compensate, but haven't found the right set) so that it resolves properly? Date math is a pain, but it is critical to my purposes.
Vendor's table
FIELD3_DATETIME TIMESTAMP(6)
My table
TIMECARD_ID NOT NULL NUMBER(10)
EMP_ID NOT NULL NUMBER(10)
IN_TIME DATE
OUT_TIME DATE
VEHICLE_ID NUMBER(10)
Also, some sample default output from each table - not sure why formatting is wierd on my table.
Vendor's table
UNIQKEY STATUS FORM_ID VEHICLE_NUMBER CREATED_DATETIME
11515780978071234994451 0 21423 24005 28-JUN-06 05.10.14.000000 PM
CHECK_DVIR NEW_DVIR SERVICEABLE DETAILS
1 1 1 everything ok
INSPECTION_TIME ODOMETER LATITUDE LONGITUDE
28-JUN-06 05.12.12.000000 PM 119885.1 44.7889490425587 -95.2167677879333
My table
TIMECARD_ID EMP_ID IN_TIME OUT_TIME VEHICLE_ID
5 20044 28-JUN-06 24005

That sounds a bit complicated. If you post your query I'm sure there will be a simpler approach, perhaps something like
where date_timestamp between cast(sysdate -30 as timestamp) and systimestampor if you prefer
where date_timestamp between systimestamp - interval '30' day and systimestampas discussed on Re: convert timestamp to date.

Compare 2 numbers with different precision

Hi all,
Using DB 10.2.0.5, I've encountered a strange behaviour today while trying to compare ORA_ROWSCN with a previous SCN sored in a column.
SELECT
h.id HID,
h.ora_rowscn HSCN,
o.id OID,
o.scn OSCN,
h.ora_rowscn-o.scn DIFF
FROM
har@REMOTE h LEFT JOIN other o ON (h.id=o.id)
WHERE
h.ORA_ROWSCN > o.scn
ORDER BY 5 desc ;
       HID       HSCN        OID       OSCN       DIFF
...{snip}...
      4213 5093868663       4213 5092916724     951939
1157 rowsWhile casting o.scn to a number gives me another resultset (this one is correct):
SELECT
h.id HID,
h.ora_rowscn HSCN,
o.id OID,
o.scn OSCN,
h.ora_rowscn-o.scn DIFF
FROM
har@REMOTE h LEFT JOIN other o ON (h.id=o.id)
WHERE
h.ORA_ROWSCN > to_number(o.scn)
ORDER BY 5 desc ;
       HID       HSCN        OID       OSCN       DIFF
...{snip}...
     70949 5093865558      70949 5093847070      18488
2114 rowsI got the same result if I use NVL(o.scn,0) rather than TO_NUMBER(o.scn).
I can't find out why this happens. Obviously, the ">" condition doesn't match when the difference is too small.
AFAIK, ora_rowscn is a NUMBER while my "scn" column is a NUMBER(12) (which should be sufficient to store my DB or remote DB's SCN).
Does anyone has an explanation?
Thanks!

Thank you, I've marked both of your message Helpful.
@Solomon, maybe you are right, I'll get a try with Materialized Views.
About my comparison problem, I think I haven't targeted the right spot. Maybe it is an index+ora_rowscn problem. Here is my execution plan:

   h.ORA_ROWSCN > o.scn

HT204053 I have two iphones with different numbers that I use my apple ID for purchases, etc. How do I get my second iphone setup on icloud? I would like to use the features of icloud for both of my iphones. Thank you

I have two iphones with different phone numbers that I use. I have one of them set up on icloud now, but do not know how to set up my second device on icloud. Both of my iphones use my same Apple ID for purchases, etc. Is there a simple way to add a device to my icloud account? Thank you in advance for any help someone may be able to give me.

To move one of the phones to a different iCloud account (if that's what you want to do), go to Settings>iCloud and turn all synced data to Off. When prompted, choose to keep the data on your iPhone. After everything is off, scroll to the bottom and tap Delete Account. This will delete the account from the phone but not from iCloud so the other phone will not be effected. Then set up a new iCloud account with a different Apple ID and turn iCloud syncing in Settings>iCloud back to On. When prompted, choose Merge. This will upload the data to the new iCloud account.
You will then have to go to icloud.com and sign into each iCloud account separately and delete any unwanted data that you don't want on the phone syncing with each account.

Numbers point to a cell with different formatting to create conditional format

Hi all, not sure if this has been brought up but my search efforts haven't found anything. I know conditional formatting is not supported in IOS numbers but I saw a buddy do a little trick a while ago and I've been trying to replicate it. On his iPad, he created a numbers spreadsheet that had a logic function (=if). And if that function was true it pointed to another cell with different formatting. The result was, the cell would become the same format as the cell it was pointing too. This created the effect of a conditional format in a sense. I can get this to work with limited effect, only if the cell is a "text" cell and not a formula. As well the background colour doesn't get picked up, only the format of the cell text itself. I'm trying to get in touch with him for help but in the mean time does anyone have any experience in this kind of method?
Cheers

As an example:
If A > B, then A-B, otherwise make it equal this other cell (D1 for example)
{=if(a1>b1,a1-b1,d1)}
And in that d1 cell I would make another formula that also does the same subtraction (a1-b1) however knowing it will be a negative number this time, I paint the cell bright red and hopefully the original cell will then look the same since it is now equal to this one.
Unfortunately it looks like this wont work. The closest thing to doing this trick I have found is pointing to a cell formatted as text, such as a blank cell. Then the original cell takes on the formatting characteristics of the text cell. The problem is the text cell is useless since it can't do any sort of math. I can't even set the cell to simply equal another one and format it as text only. So far it looks like the only conditional type of trickery I can do is make the numbers disappear by pointing to a blank text cell.
I hope that helps describe it a little better.

I have 2? How do I sync selected photos from my IPad to my IMac w/o losing all photos on my IPad which will be replaced with the photos on my IMac.You see I have two IMacs with different sets of photos. Also want to convert all Apple works docs to pages docs on my IMac. Is there and app available to do the former. many thanks. b

The iPad and related software is designed to sync with only one computer. I suggest transferring the photos from one of your iMacs to the other so that all photos are on one Mac. Same for all other files you want to sync over.
To get those AppleWorks files to the iPad you'll have to determine if Pages will open them. If it will then use the file sharing feature of iTunes to copy them to Pages on your pad.
If Pages will not open the AppleWorks files directly you'll have to save them in some format that Pages will read. These include but may not be limited to Pages and Word formats.

How can I setup an .indd with two columns with different threads so that I can export to epub?

Hi all. Sorry, english is not my native language. I´ve made an .indd: each page has two columns with different threads (is a bilingual text). When I export this .indd to .epub only appears one column from a thread following the next thread. What can i do to fix this? My indesign is CS6
Thank you

There are fixed format EPUB files as can be used for children's books, etc. where there are a lot of illustrations. However, those are very work-intensive to produce. I've never worked on one.
Anne-Marie Concepcion did a Lynda.com video on producing one.
Rorohiko produces a product called ePubCrawler which can help in produced fixed format EPUB files:

In Excel I need to two text boxes asking us to browse the files and compare the files PDF & CSV format.
Please suggest me if we have solution for this.

Hi
I'm afraid the Excel Application does not support this function currently, I am suggesting you to take advantage of a third party component to achieve this goal.
Thanks for your understanding.

Can I use iCloud to sync two devices with different apple ID's

What do you mean by "apple ID"? There's an ID you can use at the iTunes store to buy songs, apps, etc. there's an ID you can use for your iCloud account - the two can be different or the same. So which service are you referring to when you talk about an apple ID?
