  • Remove all duplicate photos

    How can I remove all duplicate of all my albums on revel?

    Revel won't allow download of exact replica in a library, so you will not exact duplicates even if they have different file names. If you have files that are similar but are different resolutions, so they aren't really duplicates and they are allowed.

    If you have the same file in the library added to albums mulltiple, which is allowed, but they must be removed manually.

  • Duplicate the action view removes all labels of rows and columns

    Hi all

    I have a pivot table dynamic, graphic only (line-stacked bar) view in OBIEE analysis that I'm trying to reproduce 4 times.

    The problem is that any display duplicate has all labels removed. I can still see the chart, but at the bottom, below the chart, where each year and month you should see, there is nothing. Therefore, you can not say months who's who for example.

    Also, during a flight over a bar in the chart, I see a local saying "year: month: value1: Value2:" where I expect to see (for example) ' year: 2014 months: February value1: 205 Velue2: 38%"." ' "."

    This problem occurs for any display, be it a bar graph, a pie, a bar line, etc.. It does not matter.

    So my clients see the pretty graphics that don't tell them anything. All they see is beautiful colors.

    Legends are suffering from the same issue, they see the lines and bars in legends, but they don't tell them that those who are.

    Is there a way to change the XML file and apply the analysis to show entries? It is very difficult to do everything again from scratch because this means creating and reformatting of dozens of views, it is painful, painful and takes days, literally.

    Nevermind, I manually edited the XMLs.

  • A script to remove all rows in the table that contains a specific text

    Hello

    I tried some old scripts but cannot move to the right solution.

    I need a script that deletes all the rows in a table that contains a specific unique word text, something like "xxx".
    Someone has an idea?

    Thank you

    Hello

    To remove a line using row.remove () method.

    Iterate if table.rows and delete the matching condition.

    If we talk about condition, be more specific - what do you mean "a line contains a text:

    ==> 1st cell contains,

    ==> any cell contains.

    Content of the line whole is an array of his cells.contents, so your text from line 1 is:

    rows [0].contents.join ("") ==> string

  • Erase all the data of the table row

    Is there a small script to make all fields in the same row (whiteboard) null? I want to erase all the data when this row is deleted.

    Hello

    This JavaScript function will reset all the fields in the line taken in;

    function clear (row)

    {

    var resetList = [];

    fields var = row.resolveNodes ("#field [*]");

  • Table Row duplicates button click, but carries with it data

    What I mean is, I have a form with a table on page 1. I created the floating fields on page two where the data entered in the the flow in text fields, which works very well. I added a button for the user to add rows to the table and the table row repeat.

    However, when I type the data into the table and click on the button to add another line, it duplicates the line containing the data that I typed in. Of course, this isn't what I want to say are you seeking. I've never had this problem before. It's because of the floating fields. What I am doing wrong?

    Hello

    You can use two tables (one on the entry page) and the other on the page of the letter that are related. See an example here: http://assure.ly/eTOXaH.

    Note that the script in the event of output from the fields in the table.

    Hope that helps,

  • Remove all lines and insert them into Oracle can make performance worse?

    I m working in a project that I need to make a batch update regularly (every 4 months) of excel files. These files have doesn´t excellent key in their ranks.

    The development of a code that deletes all lines and inserts the entire base again is easier than one who checks in all the ranks of its primary key and if necessary update. (sometimes may be a key to 5 columns).

    My question is: if I delete all the rows in the tables of the insert it again, it will cause tablespace fragmentation and in a future loss of performance?

    Is there a way to avoid this?

    Thanks in advance

  • How to identify the last instance of a dynamic table row

    Hi all

    I'm trying to figure out how to create an action for my form in Livecycle Designer ES2, which will affect the last instance of a dynamic table row. I have a table with a repeatable row where the user will enter information about a part purchased and I have buttons that allow the user to add and remove the lines. I need to create a line extra addition button which will add a new instance of the repeatable table line (this is not a problem) and disable and change the background color of the first cell in the row added. The problem I have is how to have an action that affects the last instance of a line.

    If anyone knows how to do this in Javascript, I would appreciate some advice/help.

    Hello

    I think that it is beyond providing an action. You will have a need to write JavaScript directly.  When you call the addInstance method it returns the new line, if you can do something like;

    var line = Table1._Row1.addInstance ();

    line. TextField1.border.fill.color.value = "255,0,0";

    line. TextField1.access = 'protected ';

    To find the last line and do the same thing, you can do something like;

    var line = Table1.resolveNode ("Row1 [" + (Table1._Row1.count - 1) + "" "]" ");

    line. TextField1.border.fill.color.value = "255,0,0";

    line. TextField1.access = 'protected ';

  • Add a table row

    I have a standard html table and ice div and want my client to be able to add the table lines to enter new reported issues. When in edit mode, we can change the content in the existing lines, but don't seem to be able to add a new line. Suggestions?

    Morris

    Hello, Morris,.

    You can define the rows in the table repeat regions, which will make your table a recurring element of the group. This allows users to replicate the rows in the table and add new ones.

    It seems that the first thing you want to do is to remove the DIV wrapping the table in Dreamweaver. Then, place your cursor in a table cell (theitems from the line) and go to insert > InContext Editing > create editable region. Do this for each cell in the row that you want to be editable. After specifying the editable cells in your row of the table, select the table row)your table element) and go to insert > InContext Editing > create repeating region. This will allow publishers to duplicate the rows in the table and change the cells in the row you specify as editable.

    Take a look at the next section of Dreamweaver Help for more information about the repeated regions: html http://help.adobe.com/en_US/Dreamweaver/10.0_Using/WS228F034D-1255-463f-BE80-D075F0BACF11.

    And please let me know if you need help with this.

  • find all duplicates

    Hello guys,.

    I want to know how to find all duplicate of a set of data records, in my application a duplicate is a combination of two columns, I do not want to group them, I want to know all the records duplicates


    example of

    CREATE TABLE EMPLOYER
    (
    ID NUMBER (12).
    SSN VARCHAR2 (BYTE 9),
    WGE NUMBER (10,2).
    ERR_flg VARCHAR2 (1 BYTE)
    )

    INSERT INTO EMPLOYER(ID,SSN,WGE) VALUES (1,222222222,2532)
    INSERT INTO EMPLOYER(ID,SSN,WGE) VALUES (2,111111111,2352)
    INSERT INTO EMPLOYER(ID,SSN,WGE) VALUES (3,555555555,232)
    INSERT INTO EMPLOYER(ID,SSN,WGE) VALUES (4,555555555,232)

    3RD AND 4TH RECORDS ARE DUPLICATED... I WANT TO SHOW THEM IN MY QUERY AND UPDATE THE ERR_FLG TO 1


    Thank you

    Hello

    Here's a way to get the results of a query without grouping:

    WITH     got_cnt        AS
    (
         SELECT     id, ssn, wge
         ,     COUNT (*) OVER ( PARTITION BY  ssn
                                  ,            wge
                          ) AS cnt
         FROM    employer
    )
    SELECT     id, ssn, wge
    FROM     got_cnt
    WHERE     cnt     > 1
    ;
    

    Almost all of the functions of aggregation (such as COUNT) have analytical equivalents, which can produce the same results without collapsing the data in one row per group.
    The PARTITION BY an analytical function of clause is the clause GROUP BY of an aggregate query.

    However, the update, what is wrong with grouping?
    You can use something like the query above as a subquery in an UPDATE statement, but you will get the same results more simply with GROUP BY:

    UPDATE  employer
    SET     err_flg     = '1'
    WHERE     (ssn, wge)     IN (
                        SELECT    ssn, wge
                        FROM      employer
                             GROUP BY  ssn, wge
                             HAVING    COUNT (*)     > 1
                               )
    ;
