How to format date faster than SimpleDateFormat

Hi All,
Can someone tell me way to format the date faster than SimpleDateFormat.
Thanks in advance.
Cheers!!
Puneet

At times when we declare formatter again and again,
the SimpleDateFormat's performance is less as
compared to the apache's FastDateFormat..1) Decaring it wouldn't be what makes it slow. Instantiating it would.
2) As already stated--simply don't instantiate that many of them. Create a few and reuse them.
3) So what if the other one is faster? Have you run into actual problems with SimpleDateFormat being a bottleneck? A Ferrari is faster than my car, but it makes no significant difference for how I use a car. I would not realize any meaningful speed improvement if I had a Ferrari.
4) If the other one is faster and it's that buggerall important, then use the faster one.
. So I was
trying to find out if Sun has something to solve my
problem.You can peruse the API docs as well as anybody else.
I am using the formatting in batch process
so data to process is huge.Have you found a bottleneck? Have you put a profiler on it? Have you determined that it's the parsing that's causing the problems and that creating is negligible?

Form Letter Report - How To Format Date and Number Hidden Fields

Hi
Is it possible to format date and number fields in a form letter report. This case were Paper Design shows fields as $<hire_date>. The examples in reference book only print character values which do not require formatting. I cannot determine how to achieve this. Cannot select fields from Paper Design view as per other report styles where can apply formatting. Do I have to perform formatting in the query to return date as string in format I wish for? This is not case for other report styles.
Thanks

you could add a field, set the source of the field to hire_date (assuming hire_date is a column in the data model), and put a format mask of whatever format you want. then set visible to No.
then instead of &<hire_date> you can instead type &<name of your new field>.

How to transfer data more than 255 char from excel sheet to internal table.

Hello Experts,
I have a requirement where i have a text field in the excel sheet of more than 255 char and need to be updated in the text element. To do that i need to transfer the excel sheet data to an internal table where one of the field is more than 255 char.
in the standard function module it works only upto 255 char. Can you help me if we have some other way to get more than 255 char in the internal table from excel sheet.
Thanks in Advance.
BR,
RaJ.

Using .xls, it is not possible transfer data more than 255 characters from excel sheet. However if the excel sheet is saved as Comma Delimited format or Tab Delimited format, then using GUI_DOWNLOAD function module data more than 255 characters can be transferred.
File name should be : .csv (Comma Delimited format) or .txt (Tab Delimited format)
File Type would still remain 'ASC' while calling function module GUI_DOWNLOAD
Also In the internal table declare the field type as String or LCHAR.
Eg:
TYPES: begin of ty_file,
        col_a TYPE string,
      end of ty_file.
DATA: i_file type standard table
               of ty_file
             with header line
CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
    FILENAME                      = 'C:\test.csv'
TABLES
    DATA_TAB                      = i_file

How to Format Date / Time

I found out how to retrieve date and time from the operating system, but how do i format it.
I need the short and sweet versions.
Example:
// Retrieving from the operating system.....
String system_date = new java.util.Date().toString();
Now I want to parse the date string... for instance retriving the current date in this format (DD-MON-YYYY)....
if u know another way to retrieve the date without parsing the string so I can just pull the year instead of everything....
Thank You In Advance

Try out this code:
//TO GET THE YEAR AS A NUMBER, USE DE java.util.Calendar class
Calendar rightNow = Calendar.getInstance();
System.out.println("My age is " + (rightNow.get(Calendar.YEAR) - 1971));
//TO FORMAT A DATE IN YOUR LOCALE USE, java.text.DateFormat
DateFormat df = DateFormat.getInstance();
System.out.println("The date right now is " + df.format(new Date()));
//TO FORMAT A DATE IN ANOTHER FORMAT AND LOCALE...
DateFormat df2 = DateFormat.getDateInstance(DateFormat.SHORT, Locale.CHINA);
System.out.println("The date right now in China is " + df2.format(new Date()));
I hope this soves your problem,

How to delete data older than three years from DSO

Hi all,
We needs to keep historical data in the DSO only for three years. One way of doing this is by selective deletion we can delete data older than three years but we want to make it authomated. Is it possible to add a process or ABAP program to delete data older than three years.
If it is p[ossible by ABAP code then can you please give me sample code.
Many Thanks in advance.
Harman

Some time for in case of huge volume of data selective deletion is not works, Try for "prunning" option.
It's work as follows
1)     Create DSO which is same replica of your Source DSO.
2)     Create two transformation
     a) from Source DSO to Copy DSO
     b) Another is from Copy DSO to Source DSO
3)     Transprort Last 3 years records to Copy of Source DSO using DTP Filter range for time.
4)     Once data loading from Source DSO to Copy DSO get completed delete all data from Source DSO.
5)     Now load data from Copy DSO to Source DSO.
6)     After complete loading delete entire data from Source DSO.
I use prunning process to one of my client and it's work perfectly.

How to format Data in subject line of an Email

I have an email submit button on my LiveCycle form and the client wants data from the form in the subject line of the email. I have the button set up and the patterns set up on the fields but the data in the subject line doesn't display the way it does in the fields. this is what I have.
var oDoc = event.target;
var nSubject = Page1.Top.txtEmpID.rawValue + " " + Page1.Top.dteTo.rawValue;
oDoc.mailDoc({
cTo: "[email protected]",
cSubject: nSubject,
cMsg: Page1.Top.txtLastName.rawValue + " " + "Performance Agreement"
The Employee ID is 7 digits including leading zeros (0123456) and the date is formatted MM-DD-YYYY. When it goes to the subject line it doesn't show the leading zeros (123456) and the date is formatted YYYY-MM-DD.
Any help is appreciated, Thanks.

To get the formatted date striong use formattedValue instead of the rawValue in your scriptings.

How to recieve data longer than 256?

Anyone knows the typical way to handle a large block of data (more tahn 256 which is the MAX of LC)? If you can provide me a sample code, I will do appreciate!
Neat

If you are referring to data larger than 256, the same will need to occur on the host side. You will send an apdu requesting a block of data beginning at an offset. You can pass that offset value in the P1/P2/P3(LC). The applet will send n amount of data beginning at that offset. The LE is the length of the response data the card sent back not an offset.

How to format date/time in display hints?

To those of you who know it:
One of the attributes in a VO is of Date type. To display of the date in the format of "10/25/2009 11:45 PM", I only managed to display "10/25/2009 11:45" with only the clue of the few examples provided in display hints when doing the formatting (the format mask I use is MM/dd/yyyy hh:mm). I would appreciate it if someone could advise how to display the AM/PM part of the format mask. Or better yet, point me to a source of reference for such formattnig.
Thanks!
Newman

Newman,
As suggested by Puthanampatti, you have to use 'a' in the date pattern to display AM/PM.
You can find date and time patterns in [SimpleDateFormat API doc|http://java.sun.com/j2se/1.4.2/docs/api/java/text/SimpleDateFormat.html] which describes more about the letters to be used for each pattern which you can also use with attribute display hints in VO.

How to format data for a custom group

Hi all
I have a pivot table with Actual and Budget as columns and some accounts in the rows. Since I'm using the account hierarchical column, I created custom groups for the accounts using the Selection steps pane. For example, I created a new group called Profit to combine 3 different Profit accounts and display one Profit line.
Now I want to format the data for the Profit group. I right-click on the Profit group, choose to edit the group and click on the Format button on the bottom left corner. I add some formatting, e.g. borders. When I now view the pivot table, borders have been applied to the label of the group - so the word Profit is now bordered. However, the values in the Actual and Budget columns do not have a border. Don't know what I'm missing, but I want both the group label and the values to be formatted the same way.
How can I apply formatting to the data/values for the custom group?

Yeah tried that already, it formats the entire column whereas I need just the values for the Profit row to be formatted. Seems it is a limitation only when using custom groups?

Appreciate your response.

The following will help you to extract the date and perform an arithmetic function on a date:
olddate=$(head -1 myfile | cut -c 24-29)
newdate=$(date -d "20${olddate} + 2 days" "+%y%m%d")You may have to implement some logic if the year is before this century, e.g 1999. For the rest I suggest you look into awk or sed to perform a string replacement based on character position.

How to pass data more than raw limit..

Hi,
How can i send msg payload which has more
data than 32k. I dont want to use OCI. I am
trying to send a BIG XML through AQ.
Thanks
Dhiraj.
Note in docs below it says:::
For PL/SQL, Java and precompilers the limit is 32K; for the OCI the limit is 4G.
From DOCS
RAW" ---
To store payload of type RAW, AQ creates a queue table with a LOB column as the payload repository. The theoretical maximum size of the message payload is the maximum amount of data that can be stored in a LOB column. However, the maximum size of the payload is determined by which programmatic environment you use to access AQ. For PL/SQL, Java and precompilers the limit is 32K; for the OCI the limit is 4G. Because the PL/SQL enqueue and dequeue interfaces accept RAW buffers as the payload parameters you will be limited to 32K bytes. In OCI, the maximum size of your RAW data will be limited to the maximum amount of contiguous memory (as an OCIRaw is simply an array of bytes) that the OCI Object Cache can allocate. Typically, this will be at least 32K bytes and much larger in many cases.
Because LOB columns are used for storing RAW payload, the AQ administrator can choose the LOB tablespace and configure the LOB storage by constructing a LOB storage string in the storage_clause parameter during queue table creation time.

Dhiraj,
Its a PL SQL limitation that more than 32K cannot be passed as raw.
You can use OCI Interface to achieve that. If you specifically dont want to use OCI, you can create an ADT with a lob in it and use PL/SQL to pass in raw data with size > 32K.

How to format dates in SQLExec query

I am trying to archive Lookout data to an Oracle database using SQLExec. I started with existing SQLExec code that put data into Access. Following is that code:
"Insert into wind_temp (Rdate,Wind,Temp) values ("&text(now(Timer3),"0.00000000")&",
"&text(\\SCADA1\Server\Drivers\Corral\ROCSouth.Wind,"0.000")&",
"&text(\\SCADA1\Server\Drivers\Corral\ROCSouth.Temp,"0.000")&")", 8, no);
The Rdate column in wind_temp table is date type. If I change the type to varchar2 (string) this works, so my ODBC connection is good. The problem is that for date fields Oracle needs a string in DD-MON-YYYY (i.e. 01-JAN-2002) format or string data converted to a date (i.e. to_date('01-JAN-2002 12:00:00','DD-MON-YYYY HH24:MIS')). Is there a way
using the now() or other function to build a "to_date" string like above to pass to Oracle?

Here you go:
text(now(),"dd/mm/yyyy hh:mm:ss")
This will give you slashes and not dashes and a number for the month and not the abbreviated name.
Here is the expansion that does what you need:
left(text(now(),"dd/mm/yyyy hh:mm:ss"),2)&"-"&if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="01","JAN",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="02","FEB",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="03","MAR",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="04","APR",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="05","MAY",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="06","JUN",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="07","JUL",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="08","AUG",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="09","SEP",if(m
id(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="10","OCT",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="11","NOV",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="12","DEC","ERROR"))))))))))))&"-"&mid(text(now(),"dd/mm/yyyy hh:mm:ss"),7,15)
The date I got from this was:
11-APR-2002 11:54:35
I would recommend using multiple expression objects to simplify reading the code. I included it here, all in one expression, so you could copy and paste it for testing.
I tested it on Lookout 5.0. It works.
Study the text() function and the general text manipulation functions. You can do just about anything with a little creativity.
