How to remove a line empty in a table

How to remove a line empty in a table?
This is how to remove only a line including all columns as null values...
Please help me

Sounds strange, but you can use COALESCE to achieve this.

ME_XE?create table all_nullz (col1 number, col2 number, col3 number);

Table created.

Elapsed: 00:00:00.20ME_XE?ME_XE?insert into all_nullz values (1,2,3);

1 row created.

Elapsed: 00:00:00.12ME_XE?insert into all_nullz values (null, null, null);

1 row created.

Elapsed: 00:00:00.06ME_XE?ME_XE?delete from all_nullz where coalesce(col1,col2,col3) is null;

1 row deleted.

Elapsed: 00:00:00.26ME_XE?

    Amar,

    I'm a bit confused with your logic here...

    But if you try to delete the row by clicking the button Delete you can set the immediate property to true, this function of deletion will take place without performing any validation of the entity...

  • How to remove a line empty after an anchor of the table?

    We use FrameMaker 12 on Windows 7 (64-bit) platform.

    I'm working my way down to a chapter in the content of the training. I'm at halfway in the chapter, and - as fate would have - I need start a table at the top of a page.

    When I insert a table (with a caption/title at the top), FM creates an anchor at the top of the page. The space to the right of the anchor is a blank line.  In fact, I want the table to start at the top of the page without the white line to the right of the anchor.

    That's what I tried, with results:

    I put the cursor after the anchor and press DELETE.

    Result: The text * under * the table is set up above the table.

    I put the cursor after the last piece of text on the previous page and press DELETE.

    Result: The paragraph on the previous page Stoops to the next page on the top of the table, leaving a large empty space on the previous page.

    I change the start option (Table Designer) at the top of the column (or the top of the Page).

    Result: FM leaves the anchor where she was, move the table until the next page and leaves a completely blank page where the table used to be.

    Is it possible to just go up the table so that it is on the same line as the anchor?

    (And as a design tool problem, is there ALWAYS a reason why a content developer wants a complete line of vacuum over a table?)

    Thank you in advance,


    Tim

    Assuming that your para anchor has a spacing of X:

    • In the Paragraph Designer set it for tea by anchor, base: space: below the FMP: -x
    • In the table designer for the table, set the base: space: above: -x

    >... it NEVER is a reason why a content developer wants a complete line of vacuum over a table?

    A series of tables not run-together, sure. But the hack of negative space above there are quite often do suggests a design control.

    Basically you don't have. PDF is not a file format of spreadsheet or word processing (see ISO 32000 for a description of this PDF "is").

    Content objects are "painted" on page PDF "canvas" - kinda sorta a paint-by-numbers thing.

  • How to remove the box empty?

    Hello! How are you all? Can someone tell me how to remove the empty area in a picture? For example I circle. If I save it in jpeg/png format and then will display a white space that is infact empty area if the background is set to transparent. I can choose this circle with the magic wand tool and by doing the opposite, I can select area located in front of it. is anyway to remove this empty transparent space so that any image size is the single circle?

    JPG doesn't support transparency, so when a zone is empty it fills the background color.

    PNG save transparency but then you must make sure that you are save in this format.

    Using the magic wand to target and remove the unwanted area works perfectly, but you still need once, be sure to save it as a PNG image.

  • How to remove a line in the database

    Hello

    I want to remove a line in the database... I used the (drag and drop the data control), delete operation when I push the button in the page it removes just in the session not on the database,

    This means that when I reload the session or I check line in the database, that I always find...

    I use jdeveloper 12.1.3.0.0 and business components.

    You must press the validate after the delete operation (from data controls drag / move validation operation).

    If you want to run Remove and validate the operation in a single action, in your page, you can add the button and in the action of the button write this code:

      public String DeleteAction()
      {
        OperationBinding operationBinding = BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding("Delete");
        operationBinding.execute();
    
        operationBinding = BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding("Commit");
        operationBinding.execute();
    
        return null;
      }
    

    Make sure that the "Delete" operation point to the desired pageDef VO. and don't forget that "Commit" operation existence in pageDef.

  • How to remove children lines with removal of multi line?

    Hello!

    I have a DSM process that removes the selected lines of the report, but it gives an error if the line have a child row in another table, so I have to go to this report and remove these first.

    Just add somewhere in the DSM process something then it removes children lines too, or I have to create new process for this?

    Hi EgaSega,

    DELETE will work if there is no foreign key constraints that refer to the line to remove.

    If you don't have foreign key constraints, you can change them to 'ON DELETE CASCADE '. This way, if you DELETE a row in a parent table, all child rows will be auotmatically DELETED, too.

    There are also "ON DELETE SET NULL', which allows you to DELETE the parent rows with children. When you DELETE a parent, child rows are not automatically DELETED, but the columns that pointed to the DELETED parent are automatically changed to null.

    Check out this old thread of discussion forum SQL and PL/SQL for more details:Delete record based on the ID of the main table

    Hope this helps you,

    Kind regards

    Pls advise.

    Thank you

    I guess that the condition is a column. Check if the condition works.
    Remove the space before the end if.
    If this condition does not work, check if the field is referenced correctly.
