Converting 7.3.4 LONGs to 8.1.7 Varchar2(4000)

Hello all,
I have a table in 7.3.4 that has a long field because the data was just about 3500 characters long. Now we are upgrading to 8.1.7 and I want to change all the long fields to varchar2(4000) and insert the data. Can anyone tell me how to do this?
Thanks.

You can create column of CLOB datatype and use TO_LOB function to convert long into CLOB.
add a column with CLOB datatype then insert data from long to clob and then drop long column.
or create another table similar to original one but clob column instead of long column. insert data into new table then rename both tables accordingly.

Maybe this would work?
StringTokenizer st = new StringTokenizer(yourString, " ");
long l = 0;
while(st.hasMoreTokens()) {
l += Long.parseLong(st.nextToken()).longValue();

How to convert clob column to long

Hi,
Is there any way to convert clob column to long.
Here below is my scenario..
Instead of using substr function
CREATE OR REPLACE PROCEDURE proc AS
sql2 clob := '';
sqlstring1 LONG;
sqlstring2 LONG;
sqlstring3 LONG;
sqlstring4 LONG;
sqlstring5 LONG;
sqlstring6 LONG;
sqlstring7 LONG;
sqlstring8 LONG;
sqlstring9 LONG;
sqlstring10 LONG;
BEGIN
FOR sql1 IN (SELECT info FROM emp)
LOOP
sql2 := sql1.sql_string;
sqlString1 := dbms_lob.SUBSTR(sql2, 8000, 1);
sqlString2 := dbms_lob.SUBSTR(sql2, 8000, 8001);

sqlString7 || sqlString8 || sqlstring9 ||
sqlstring10;
END LOOP;
COMMIT;
END proc;
Any help really appreciated
Thanks

We cannot execute clob dynamically.That's what I said: execute immediate doesn't support CLOB!
But you can concatenate two long's:
SQL> DECLARE
   l_stmt1   LONG;
   l_stmt2   LONG;
BEGIN
   l_stmt1 := RPAD ('BEGIN ', 32500, ' ');
   l_stmt2 :=
       RPAD (' dbms_output.put_line(''Hello World'');', 32500, ' ')
       || 'END;';
   DBMS_OUTPUT.put_line ('Length of statement: '
                         || LENGTH (l_stmt1 || l_stmt2)
   EXECUTE IMMEDIATE (l_stmt1 || l_stmt2);
END;
Length of statement: 65004

Converting byte[] to short, long, etc.

I need to packetize the data with my own header embedded in the data. The header field is composed of data types: short, byte, and long. Since the header will be transported over the network using UDP socket, it will have to be converted to type byte[].
Is there a clean way to convert from byte[] to short, and long data types? Or do I have to concatenate bytes and type cast them? How do I even type cast byte[] to short? Thanks.

Have a look at the ByteBuffer class. You can wrap a byte
array in such a buffer and write other types (like ints or longs etc)
to the byte array through the buffer. Of course you can read those
values back again using the buffer.
kind regards,
Jos

How to convert string date to long (or Unix date)?

I'm having difficulty in converting a user supplied date in the format mm/dd/yyyy to a long format such as 1035462807000. Since it's being entered by the user I can't just use the current system date. Any suggestions? Thanks!

Hi man, tsith Gave a good beggining, why dont you try the next code
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.text.ParseException;
import java.util.Date;
public class DateToUnix{
    public static void main(String args[]){
        getDateAsLong();
    public static void getDateAsLong(){
        String sStartDate = "12/01/2002";
        Date theDate;
        DateFormat sdf= new SimpleDateFormat("MM/DD/yyyy" );
        try {
            theDate = sdf.parse( sStartDate );
        }catch(ParseException e ){
            theDate = new Date();
        System.out.println( "Converted Start Date:" + theDate.getTime());
}No mather how you get a Date object, the value you are looking for is a long, and you can get it from such object with the getTime() method.
Take a look at the Java API @ [http://java.sun.com/j2se/1.4.1/docs/api/java/util/Date.html#getTime()]

Converted YouTube videos no longer work

I have been converting some YouTube videos for my own offline use for some time to view on my iPod Touch. I use a little program called TubeSock.
Since 2.0 software was released for both iPod Touch and the iPhone 3G all of my converted videos no longer work. Apple changed something. I also have an e-mail into TubeSock to see if they have an update in the works.
Anyone else experience this problem and if so any solutions?

Converting jlong to unsigned long

Hi Everyone,
I am calling a interface from a dll file which need a unsigned long or long as a parameter. In the C program side, how can I convert the jlong to unsigned long or long and then call the interface from the dll file? Also, how can I convert the long back to jlong and return back to Java side? Thank you.

IMac Intel 10.6.7 dont convert my blendfiles any longer

Hello
For years I have animate on Blender 2.4 - 2.5.7 64 bits and have converted plenty of blendfiles to videos at Vimeo and YouTube. But after Apple upgrade iMac from 10.6.6 to 10.6.7 64 bits there is no longer any possible way to get my blendfiles converted to videos.

Ignore all these suggestions from the post above. They won't help, may be harmful and slow down your computer even more. Do try a Safe Boot, SMC and PRAM Resets, remove any login items, and test from another account.
Remove all items in your:
/Library/Caches
/Library/LaunchAgents
/Library/LauncDaemons
~/Library/Caches [~ - Signifies your user level, the others were the main computer folders]
~/Library/LaunchAgents
I finally found the Activity Monitor. I selected All Processes and see the %CPU but I don't know what I am exactly looking for.

How to convert Works doc no longer having Works?

I have been sent a large Works document. No longer having Works, I am trying to figure out how to convert it into .rtf of some other form that is readable.

Since you've posted in the AppleWorks forum, by "Works" I assume you mean AppleWorks. There are a few options to get to the contents of that file.
The easiest & most reliable option other than using AppleWorks or Pages 4 or earlier would be to open the file with LibreOffice. It's a free, open source, Office clone that does a very good job of opening AppleWorks & ClarisWorks files. You can then save them as RTF or Word.
Second would be to open the file with TextEdit that comes with OS X. You will get a lot of "garbage" formatting text before & after the actual text. That formatting can be many pages long.
Third would be to look at the options available from Panergy Software. They do have demo software to try.

[Q-Pro] Converting video taking incredibly long?!

Hi,
I'm using quicktime pro to convert some MKVs with subtitles to AVIs. The input MKVs are about 140mb in size, and 24 minutes long. Quicktime gives me this information about the videos:
http://img12.imageshack.us/img12/5286/picture7ks0.png
I am converting them with these settings:
Video Settings: http://img22.imageshack.us/img22/9579/picture5uo2.png
Audio Settings: http://img19.imageshack.us/img19/6564/picture6nk5.png
Doing this takes about 3 - 4 HOURS per file! Why so high? Are there any alternative methods that will preserve the subtitles (Convert them to video)? At this rate, it would be quicker to capture the screen video with something like Snapz X and convert it from there...
My hardware is a 2.4ghz Early 08 Macbook Pro, so I doubt it's a hardware limitation.
Thanks,
Dave.

So. You're trying to take some "out of date" Matroska files into another silly format like AVI?
What a waste of time and your resources.
The Cinepak codec (AVI export codec) was written for 1993 machines and is so out of date that it has been ended by its creators (Microsoft). The audio codec is equally deprecated and shouldn't be use for modern machines.
If the files still "play" what is the need for the conversion? If you need a converted file why use such outdated codecs?
What is your goal?

Output_text converter in EA4 no longer working

I have been using the NumberFormat converters in EA3 for output_text with no problem. Now I am trying out EA4 and the standard converters have stopped working. So, I have build my own converter and registered it in faces-config.xml just like in cardemo. my jsp looks like:
<h:output_text id="monQuota" converter="swampCurrency" valueRef="TCompCalc.monQuota" >
</h:output_text>
the faces-config.xml section looks like:
     <converter>
     <description>Currecny Converter</description>
     <converter-id>swampCurrency</converter-id>
     <converter-class>swamp.webbeans.SwampCurrencyConverter</converter-class>
     </converter>
The class is not even being invoked and I double checked the spelling of everything many times over. I am at a loss here. Please help. Thanks.

Following code is working.
Try it.
<h:input_text id="ritsu" valueRef="waribikiBean.rate" converter="Number">
     <f:attribute name="numberStyle" value="percent"/>

Converting Date-Time to Long Date in a string that is stored in a formula

The following are 2 verions of formulas that I've tried in placing the long date on a report. I want the JUD_T_MEETING_NOTICE.MEETING_DATE to be displayed on the letter if Outcome_ID = 3.00 as April 29, 2009. The field's fomat in the table is 04/29/2009 and neither of the formula's below worked. I tried formatting the date as a separte formula, as shown in Formula #2 below, but the formatting defaults to the original DataType. Anyone have any ideas on how to format the date within the string in the formula?
FORMULA #1:
IF {JUD_T_MEETING_NOTICE.FK_OUTCOME_ID} = 3.00
THEN 'I received the enclosed report(s) for review. To resolve this matter, you must contact the office at ' & {@HallPhone} & ' to schedule a meeting to discuss the incident with me. This meeting must occur by ' & DATETIMETODATE({JUD_T_MEETING_NOTICE.MEETING_DATE}) & '. If you have a conflict with this deadline, please let me know as soon as possible to make alternative meeting arrangements.'
ELSE IF {JUD_T_MEETING_NOTICE.FK_OUTCOME_ID} = 9.00
THEN 'You missed your scheduled meeting.'
FORMULA #2:
IF {JUD_T_MEETING_NOTICE.FK_OUTCOME_ID} = 3.00
THEN 'I received the enclosed report(s) for review. To resolve this matter, you must contact the office at ' & {@HallPhone} & ' to schedule a meeting to discuss the incident with me. This meeting must occur by ' & ({@FormatMeetingDate}) & '. If you have a conflict with this deadline, please let me know as soon as possible to make alternative meeting arrangements.'
ELSE IF {JUD_T_MEETING_NOTICE.FK_OUTCOME_ID} = 9.00
THEN 'You missed your scheduled meeting.'

Assuming JUD_T_MEETING_NOTICE.MEETING_DATE is a date field, modify your formula to:
totext(({JUD_T_MEETING_NOTICE.MEETING_DATE}),"MMMM dd, yyyy")
If it is not a date field but a string, then
totext(cdate(JUD_T_MEETING_NOTICE.MEETING_DATE ),"MMMM dd, yyyy")

Dear Veerandra,
I have already checked in R/3 as you had mentioned. But as I said earlier, could not catch the correct record, since, did not had proper info. UMSA1 refers to Annual Sales, which are empty in R/3 and BW as well.
I have undertaken the following actions but all failed.
1. Replicated the data source, activated the transfer structure through a program and the load was run but the load failed with the same issue.

How to convert double to unsigned long integer for cRIO analog output?

All,
Having issues sending out my arbitrary waveform to my cRIO analog output. My values are doubles and by the time I send them out, they have been converted to U32 values and are all turning out as zeroes. This led me to assume two things: 1) That cRIO analog output can only output integers since the values need to be deployed in the memory first and 2) that I'm missing a step in the conversion process. My values range from 0-8, therefore I don't expect that the simple conversion tool in labview should make everything into zeroes.
Any help?

Since we are using the cRIO's FPGA interface, you really should be doing most of this inside of the FPGA. Use DMA FIFOs to pass your data between your RT and the FPGA (and visa versa).
On your FPGA, you can have a loop that just reads the analog inputs at whatever loop rate you want. You just send the data to the RT using a DMA.
Similarly, use a DMA to send your analog output values to the FPGA. The FPGA can have another loop that reads the DMA and writes the value to the analog output. This should be done in the FPGA since you can have the FPGA send out the values at a given (and deterministic) loop rate.
