Populate a table reading the data from a TXT file

how can I populate a table reading the data from a TXT file?
thanks

Hey Kevin!
Using FORMS.TEXT_IO to bulk load data from a file strikes me as re-inventing the wheel. It is just about justifiable in a self-service environment, but I regard the EXTERNAL TABLE is a better solution for that situation as well.
The same applies to UTL_FILE. I think the ability to read text with UTL_FILE is primarily intended for read file-based configuration or file manipulation/processing rather than data loading.
Re-writing a text file into SQL statements is too much like hard work (even with an editor that supports macro definition and regular expressions) for no real benefit. You lose all the bulk load peformance you would get from SQL*Loader. But for QAD I'd probably let you off with it.
You missed out one obvious alternative: using Java to turn the contents of an XML file into a CLOB and inserting it into a table which is read by a PL/SQL procedure that parses the XML records and insert the retrieved data into a table.
Stay lucky, APC

What is the 'quickest' way to read char data from a txt file

Hello,
What is the 'quickest' way to read character data from a txt file stored on the phone to be displayed into the screen?

To be even a bit more constructive...
Since J2me does not have a BufferedInputStream, it will help to implement it yourself. It's much faster since you read large blocks at ones in stread of seperate chars.
something line this lets you read lines very fast:
while ( bytesread < filesize ) {
         length = configfile.read( buff, 0, buff.length );
         // append buffer to temp String
         if ( length < buff.length ) {
            byte[] buf = new byte[length];
            System.arraycopy( buff, 0, buf, 0, length );
            tmp.append( new String( buf ) );
         } else {
            tmp.append( new String( buff ) );
         // look in tmp string for \r\n
         idx1 = tmp.toString().indexOf( "\r\n" );
         while ( idx1 >= 0 ) {
            //if found, split into line and rest of tmp
            line = tmp.toString().substring( 0, idx1 );
         /// ... do with it whatever you want ... ////
            tmp = new StringBuffer( tmp.toString().substring( idx1 + 2 ) );
            idx1 = tmp.toString().indexOf( "\r\n" );
         bytesread += length;
      }

Updating Table using the data from a flat file

Hi,
I have a table called emp;
Name,
empno,
accountno,
amount.
This table is filled with values of name and empno.
The columns accountno and amount are empty.
I have a flat file created in some folder.
Contents of the flat file can be like this:
mani | 23 | 123 | 1000
spr | 22 | 342 | 2133
asjf | 54 | 432 | 2345
I need to access the file in the specified location, read all the records one after the other in the flat file and update the table "emp" with the values in the flat file.
Row after row all the records in the file should be updated to the table.
I found out some way to do this - its sqlloader - But it loads the data from a file to the table - i dont need that - i need to update the table.
Let me know how this can be solved ?????????
Thanks in advance.......

Just to clarify Andrew's point, you can use external tables as the source table for an UPDATE statement. You cannot use them as a target for an UPDATE statement (i.e. you can't update the text file from an Oracle table).

How to read the data from an excel file into MYSQL by java language

Hi all,
I have some data in excel spread sheet and I want to put the data into MYSQL data base. I created the tables in MYSQL> How can I write a program in JAVA that puts the value from excel sheet to mysql??
I would appreciate your help
regards

By typing code at the keyboard... but presumably you meant to ask what code you should type.
To get data out of Excel there are a few alternatives. The Google keywords I would use to find them are "java excel". I use Apache POI but there are other possibilities, I believe. As for getting the data into MySQL once you have extracted it from Excel, you would use JDBC. But you already knew that, didn't you? You did find the JDBC forum.
In general it's better to ask a specific question on a forum. If you don't have a clue (which is the way we all start out) then just telling people that isn't going to be helpful. The best you're going to get is links to tutorials, which you could perfectly well have found for yourself by simple web searches.

Is there any way to read the data from an excel file w/o using a loop structure?

I am retrieving a large amount of data (multiple sheets) from an excel file and would like to extract the entire range without retrieving individual cell values(too slow). I can write an range all at once but cannot read it.

If you are able to write a block of data, then you should be able to read a block. The four requirements that you want to verify are:
1. The Range specified must match the exact size and location of the data block you want to read
2. The returned data is in a 2D array of Variants (either strings or numbers)
3. Use Variant to Data to convert to 2D DBL or 2D Strings
4. Check for the correct orientation for your application (use transpose if it is not)

How to update a table AUTOMATICALY with data from a .txt file??

HI ,
I want to upload data which is in a notepad file and Create a table. This notepad file stores a string of datas. Here, the data comes in to the .txt file every second.
(The data is actually stored into the notepad file when a program is executed in Processing.js software)
Is it possible to do the following using APEX ? ?
1. This table has to be updated automatically once in 2 minutes (I want this completely automatic, no human intervention -- no update buttons)
2. A report is to be created in a apex application with this table, it should reflect the updates in the table every 2 minutes.
Is it possible?? give your ideas.. I want to do this soon for my engineering project :) Any help from you is appreciated. :)

And how do you expect your database server to access a local file in your machine ?
Is the file accessible from outside your machine say inside a webserver folder so that some DB process can poll on the file ?
Or, is your DB server in the same machine where you have the text file ?
You will have to figure out the file acess part before automating user interaction or even auto-refreshing.

TO Read the data from the I/P payload of the proxy

I want to know is there any function module or report available to read the data from the
payload of the proxy. As we can see the data in the input payload for the prticular
message in sxmb_moni tcode.Is there any table where this data will be stored.
And also I have to update one Ztable with XML Message ID,Sender Interface Namespace,
Sender Interface Name as and when this proxy is triggered. For this I will have to implement the
class for the interface in the sproxy tcode and in this implementation i will update this
ztable but my problem is how will i get this values there.
In debugging I found one report rsxmb_display_msg_vers_new is submitted in sxmb_moni to show ll these details but
looking specially foe the paylod data.
Your help is highly appreciated.
Thanks.

Hello PawanG ,
It is very simple to find out all DB tables involved in the rsxmb_display_msg_vers_new . Steps below:
1. run tcode SE30
2. click "program" radio box, input RSXMB_DISPLAY_MSG_VERS_NEW as program name, click "Execute" button.
3. input an valid message uuid in the "Message GUID" field and execute.
4. go back to SE30,click "Evaluate" tab
5. click "DB tables".
Then all DB table name and description are listed there. I am sure you can find what you need. Good luck!
Best Regards,
Jerry

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.
