How to remove the last line of Utl_file

Hi I have a requirement to write the output to a file. But everything I try the last line is coming as white. I can't understand why UTL_file last blank line as null. Is aby wat to fix this problem?

/

Declare

Lfilehandler Utl_File.File_Type;

Lfilepath varchar2 (100);

Varchar2 (100) Lfilename: = "TESTFATCAFILEGEN.txt";

Lhead VARCHAR2 (2000);

Begin

Dbms_output.put_line (' started read directories ");

SELECT Filepath

IN Lfilepath

OF Interfacefileformathdrtbl

WHERE Interfaceid = "FATCAPREXTFEED";

Dbms_output.put_line ('found directory');

Lhead: = ' this is a test generated file to test if the generation of the file that is happening or not. "

Lfilehandler: = Utl_File.Fopen (Lfilepath, Lfilename, 'W');

Utl_File.PUTF (Lfilehandler, Lhead |) '\n');

Utl_File.fclose (Lfilehandler);

Dbms_output.put_line ('generation of the file is complete");

exception

While others then

Dbms_output.put_line ('down in the generation of file');

Dbms_output.put_line ("sqlerr" |) SQLERRM);

End;

/

UTL_FILE adds always new line at the end of the file if you use text mode. You must use the byte mode:

Declare

Lfilehandler Utl_File.File_Type;

Lfilepath varchar2 (100);

Varchar2 (100) Lfilename: = "TESTFATCAFILEGEN.txt";

Lhead VARCHAR2 (2000);

Begin

Dbms_output.put_line (' started read directories ");

SELECT Filepath

IN Lfilepath

OF Interfacefileformathdrtbl

WHERE Interfaceid = "FATCAPREXTFEED";

Dbms_output.put_line ('found directory');

Lhead: = ' this is a test generated file to test if the generation of the file that is happening or not. "

Lfilehandler: = Utl_File.Fopen (Lfilepath, Lfilename, 'WB');

Utl_File.Put_RAW (Lfilehandler, UTL_RAW. CAST_TO_RAW (Lhead));

Utl_File.fclose (Lfilehandler);

Dbms_output.put_line ('generation of the file is complete");

exception

While others then

Dbms_output.put_line ('down in the generation of file');

Dbms_output.put_line ("sqlerr" |) SQLERRM);

End;

/

  • How to remove the black line with a canvas stacked at run time?

    Hi all
    I developed a canvas stacked in a table of content, when I run the form takes the apeared canvas stacked with a black line.
    How to remove this line, or how to remove this line at run time?
    I tried to do by putting (no line) in the Toolbox of the line color tool after selecting black line one and after selecting the stacked another painting once, but this has not solved the problem!

    I need something else:
    I put the canvas stacked to the block of data in detail and did not appear since I run the query in the database block
    How to make appear stacked directly canvas before you run the query in the master data block?

    What is your version of forms? I don't know what black line you're talking about.

    Regarding the display of the canvas, first make sure it isn't about who has the focus and she rides (located under the canvas completely or partially) your canvas stacked, this will cause to the canvas to hide in order to display the item that has the focus. And you can also try using SHOW_VIEW ('your_stacked_canvas'); in your form, this will show the stacked canvas.

  • How to remove the default line break when you export in XML format?

    Hello

    I'm using FDK 11 to convert a FrameMaker to XML file. Basic example as in the "guide structured Import/Export API Programmer" works very well. But all my files frame long paragraphs which, then the conversion is a line break after a length that appear to be the default. Hereby, the length of the XML and the readability becomes tedious. Here is the snapshot of the transformation and the piece of code used. Please let me know if there is a function that allows to eliminate this default behavior.

    #include "futils.h".

    extern VoidT Structured_ApiEmergency ((VoidT)) FARGS;

    extern VoidT Structured_ApiInitialize ((init IntT)) FARGS;

    extern VoidT Structured_ApiCommand ((command IntT)) FARGS;

    extern VoidT Structured_ApiNotify FARGS ((IntT notification,

    Hi Vincent,.

    You use a structured application? If so, you might try reading/writing as a rule:

    writer

    {

    line break is 1000 characters;

    }

    .. .or whatever length you deem appropriate.

  • Remove the last Chr (13) & Chr (10) of a string

    Hello, all.

    I am trying to get confirmation of the files to download on Amazon for its program "Charge when ship".  I have the file create as it should with one minor exception.

    I'm creating a variable, giving him the information header column and that finishing by Chr (13) & Chr (10); I'm a loop in a query to add information, each iteration bugs Chr (13) & Chr (10) at the end of it; I'm taking this variable and writing data to a file using CFFILE.

    But I think that the last Chr (13) & Chr (10) is that servers Amazon think there is a line of information that it really is, and it's one mistake.

    Can someone tell me how to remove the last Chr (13) & Chr (10) of the variable before writing this file?

    Thank you

    ^_^

    Trim() the variable or modify the code, so it does not generate an extra newline.

    Because your content has a header, place the new line at the beginning of each iteration of the query characters.

    #chr (13) ##chr (10) # #ColumnA # ColumnB #... etc...

  • How to remove the numbers on blank lines without fully justify above the text?

    Hello everyone.

    I have a problem with my numbering.  I would like to delete the line numbers where there is no text.  But when I back off the line of text without deleting the number, then shift + return to add a paragraph break 'justifies all lines'.  He said that it's always "justify the last line aligned to the left", but is not, and I can't change it back. I tried to manually change the justification, but it is so hard to do with all the paragraphs, and it looks like not equal. I have attached a few screenshots to illustrate my problem.

    Anyone know how I can remove the numbers of the lines without text without manually clicking the line line, ranging from 'bullets and numbers' and clicking on 'none' for each line?

    Or if I can't do that, do you know how I can stop the above paragraph that justify completely once I deleted the number of rollback?


    Thank you very much in advance, I really appreciate all the help you can give.  It's great that forums like this are there to help.


    justification issue.jpg

    Above is the screenshot where you can see that there are a number (25) on the empty text line.
    This is when I removed by backspacing of the line and then shift + return to add a new line, but her line above is fully justified, and not justified with the last line aligned to the left.

    justification issue2.jpg

    Thanks for your help!  Natasha, a user of InDesign beginner.

    Return shift is a forced line break, so you now a last blank line, and is the one who remains aligned. ID does exactly what it's supposed to.

    Instead of trying to use blank lines to separate paragraphs you should use space after or front of the space.

  • [ADF, JDev 12.1.3] To run a query on the fly is always necessary to define a VO? How to get the Id of the last line inserted in a VO...

    Hallo,

    Sometimes, in the code for my application, I need to run smaller queries to retrieve data from the database.

    I wonder if for these queries, it is necessary to define a View object or if I can avoid this for example creation and execution of a VO on the fly.

    In this case I would not define a VO, given that queries will be never used to display data, but only for the internal logic.

    A use case, I want to solve it next.

    I would like to create a function to be used after validation for last inserted record by a user in a TableVO.

    For example

    Select the Id of the Table where UserId =? and Type =?

    The query should be run in a managed bean...

    public String okButton_action() {}

    OperationBinding operationBinding is BindingsUtils.getBindings () .getOperationBinding ("Commit");.

    Object result = operationBinding.execute ();

    If (! operationBinding.getErrors () .isEmpty ()) {}

    Error handling

    return;

    }

    Here, I need to:

    1. run the query to get the Id of the last inserted record

    2 call the setCurrentRowWithKey on the TableVO to update the display

    and get the Id (identity/auto-increment) than the database

    assigned to the field

    return "return";

    }

    If I can create a function that creates / runs the VO on the fly and return the value ID... It is best to create it in a class of public services or in the implementation class TableVO?

    I need to get the Id of the last line inserted since the ADF is not able to manage MS SQL Server identity fields (it seems that REFRESH AFTER INSERT cannot be used with non - Oracle DB).

    Any notice will be welocome.

    Thank you

    Federico

    The query should be run in a managed bean...

    Much better to execute the query in the template project.

    Example query: http://amit-adf-work.blogspot.com/2013/09/how-to-execute-sql-using-adf-application.html

    If I can create a function that creates / runs the VO on the fly and return the value ID... It is best to create it in a class of public services or in the implementation class TableVO?

    If you have the function that accepts the SQL as a parameter, then this should go to class util.
