Selection of several columns in the variable of a string

Hi all

Is there a trick how to select the values of all columns in a single variable of type varchar?

Consider that une_table has 5 columns of data type VARCHAR or NUMBER.

DECLARE

vvc_String VARCHAR2 (1000);

BEGIN

SELECT * INTO vvc_String une_table;

END;

/

Thanks for the tips.

Use dynamic SQL statements:

SQL > CREATE TABLE UNE_TABLE
2 AS
3. SELECT *.
4 OF DEPT
5 WHERE ROWNUM = 1
6.

Table created.

SQL > DECLARE
2 vvc_String VARCHAR2 (1000);
3 v_stmt varchar2 (10000);
4 BEGIN
v_stmt 5: = Q'[select "]';
6 for v_i to (select column_name from user_tab_columns where table_name = 'Une_table"of order of column_id) loop
7 v_stmt: = v_stmt | ' || ' || V_I.column_name;
8 end of loop;
9 v_stmt: = v_stmt | "to une_table";
10 run immediately v_stmt
11 in vvc_String;
12 dbms_output.put_line (vvc_String);
13 END;
14.

    When in the second query, I sorted out only for age, you saw it there two 26 years old Keita, there was first Agayev, then Taghiyev. But if I want to get the family names in descending order when there are two very old person, then I will add the second column in the order by clause

  • Why not the type of the variable is a string?

    Hi, I need your help. \(´o `)/

    When I'm "DropDownList.items", the type of the variable dose not become the 'string. '
    Why?

    ------------------------------------------------------------------------------------------ ----------------------------------------
    var ddList = new Array();
    ddList = ["adobe", "DSP", "Japan"]; any value string table

    / * Create window * /.

    var = DLG

    "dialogue {text:"Interface of Script", limits: [200,200,460,350],"+}.

    "panel0:Panel {limits: [10,10,240,140], text:", properties: {borderStyle: "engraved", su1PanelCoordinates:true}, '+}.

    "ddownlist1:DropDownList {limits: [10,20,100,45]}, ' +.

    "button1:Button {limits: [10,55,100,80], text: 'Ok'}, ' +.

    "button2:Button {limits: [110,55,200,80], text: 'Cancel'}}} ';


    var win = new window (dlg, "click on the ok button!");

    for (var i = 0; i < ddList.length; i ++) {}

    Win.panel0.ddownlist1.Add ("Item", ddList [i]);   Add items to doropdownlist.

    }

    Win.panel0.ddownlist1.selection = 0;

    / * When the "ok" button is clicked... * /.
    Win.panel0.button1.onclick = function() {}

    var ddownlistItems = win.panel0.ddownlist1.items;

    for (var i = 0; i < ddownlistItems.length; i ++) {}

    / * If when 'isNaN' command was returned to 'true', while the type of the variable is "string", if it was referred to 'false', so no 'chain '.  *****/

    Alert ("ddownlistItems [" i + "] plus" + IsNaN (ddownlistItems [i]));

    }

    }

    Win.Show ();

    ------------------------------------------------------------------------------------------ ----------------------------------------

    I tried this script, "alert" has been returned "ddownlistItems [0] = false '.

    but the setting of the components dropdownlist used table of "channels".

    Why not the type of the variable is a string?

    Thank you.

    Because you do not test the chain only the index.

    try...

    Alert (ddownlistItems [i] + "=" + isNaN (ddownlistItems [i] .text));

  • Several "columns" in the charts in SVG/FLASH?

    I need to create a pie with three elements... both are derived from a column in the database, while the latter is derived from another column. I've been playing with this for the last couple days.

    Because I know so little about this stuff, my last resort was to create hidden objects, with a SQL process to update the time "before the header" this work... but I can't understand how to obtain these three elements in my pie!

    Here are my three sql statements, that I need to enter a pie chart:

    Point 1: "Total needed.

    SELECT COUNT (PRODUCT)
    OF PRODUCT_DATA
    WHERE PRODUCT = 'NO '.
    AND PRODUCT_TYPE = 'HOME'

    Point 2: "update more than 10 years'

    SELECT COUNT (PRODUCT_DATE)
    OF PRODUCT_DATA
    WHERE PRODUCT_DATE < = TO_DATE (March 30, 1999 "," DD-MON-YYYY "")
    AND PRODUCT_TYPE = 'HOME'

    Point 3: "update < 10 years."

    SELECT COUNT (PRODUCT_DATE)
    OF PRODUCT_DATA
    WHERE PRODUCT_DATE > = TO_DATE (March 30, 1999 "," DD-MON-YYYY "")
    AND PRODUCT_TYPE = 'HOME'


    (Ideally I would replace the 30 March 1999 ' with TO_DATE (TRUNC (SYSDATE)-10 years, 'DD-MON-YYYY'), but have not thought too much about it yet!)

    Related to this... the above information has been imported from and Excel spreadsheet. The imported fine paintings... but there is a page with several graphics/tables which were all different formulas

    I have created a calculation to update three points... but could not figure out how to put them in the pie chart:

    P5_TOTAL_REQUIRED
    P5_TOTAL_OVER_10YRS
    P5_TOTAL_UNDER_10YRS


    Appreciate any help!

    KSL.

    Hello

    You can use UNION ALL to gather statements:

    SELECT NULL LINK, LABEL, VALUE FROM (
    SELECT 'Total Required' LABEL,
    COUNT(PRODUCT) VALUE
    FROM PRODUCT_DATA
    WHERE PRODUCT='NO' AND PRODUCT_TYPE = 'HOME'
    UNION ALL
    SELECT 'Update Over 10YRS' LABEL,
    COUNT(PRODUCT_DATE) VALUE
    FROM PRODUCT_DATA
    WHERE PRODUCT_DATE <= TO_DATE('30-MAR-1999', 'DD-MON-YYYY') AND PRODUCT_TYPE='HOME'
    UNION ALL
    SELECT 'Update < 10Yrs' LABEL,
    COUNT(PRODUCT_DATE) VALUE
    FROM PRODUCT_DATA
    WHERE PRODUCT_DATE >= TO_DATE('30-MAR-1999', 'DD-MON-YYYY') AND PRODUCT_TYPE='HOME'
    )
    

    To the date of issue, you can use:

    ADD_MONTHS(SYSDATE, -120)
    

    Who will deduct 10 years (120 months) from now

  • Mapping of several columns in the source in 1 target with the source Excel file

    Hello

    I use to load Excel files in HFM FDM 11.1.2.1.
    In Excel, I had 3 columns that need to be mapped in 1 column target using a few rules and mappings. Forest to source file should work in all cases.

    For example,.

    Source:
    A, B AND C
    1 company 1 xxx
    2 yyy Company2
    1 Company3 zzz

    mapping for B:
    Company 1 C1
    C3 Company3

    mapping for C:
    C2 Company2

    target after confirming:
    C1
    C2
    C3

    I take data from B or C according to data in A (1 or 2).


    I found several ways to do so, but they are not perfect:

    1 map columns B and C to the correct value (#C1, C2) and use scripting conditional on a column (for value correctly mapped either column B or C).
    The problem here is that I can not break through the low PIF when B and C are mapped to values other than [none]. Can this been bypassed?

    2 use DataPump import Scripts for concatenating the sources in one column only and use the tables mapping standart on 1 column.
    The problem is that DataPump import Scripts do not work with the source files Excel. Is this correct? I could find a word in the documentation...

    3. map columns B and C [None] script well but fat on the column, as:
    If (varValues (13) = '1' and varValues (39) = "Company1")) then
    Result = "C1".
    ElseIf...

    Which is horrible, and it would be very difficult to add new mappings in the script. But it works.

    4. logical accounts. I can't use it I need to drill down.

    Could you recommend me some better way to do this simple task to work?

    It's a bit that I coded something like that in VBA, so you will need to do a bit of cleanup; However, it should get you well in a way that might work...

    Why not add a formula in the excel file, once it is downloaded? (I guess the excel file that is being loaded is not something that you could develop a formula to start?)

    on error resume next 'make sure all commands are executed.  If something happens in code and file is open, we don't want to leave it open...
    
    Set objExcel = CreateObject("Excel.Application")
    Set objWorkbook = objExcel.Workbooks.Open("")
    Set objworkSheet = objWorkbook.Sheets("")      'OR you could use ordinal
    
    objExcel.Application.DisplayAlerts = False
    objExcel.Application.Visible = false
    
    for x = 1 to 100   'I'm just doing a loop for the sake of doing a loop.  You might want to loop through rows and for each row that has a
          'value in col A, make the formula and then break out of loop so you don't add a metric ton of unnecessary formulas
        objworksheet.Cells(x, "C").Formula = "=A" & x & " + B" & x      'i.e. =A1+B1
    next 
    
    'Save the changes
    objWorkbook.Save 
    
    'Close the workbook
    objWorkbook.Close
    
    'Quit application  (important)
    objworksheet = nothing
    objworkbook = nothing
    objExcel.Application.Quit
    objexcel = nothing
    

    NOTE: Microsoft DOES NOT officially support office (i.e. what we do above and what of FDM backstage I guess) seems to work very well, but in most cases, etc.. Be careful about cleaning to ensure that all memory is released and that the instance of excel stops.

  • question [10g] Simple on the selection of a column in the same record as the value min

    I have the sample data to illustrate my question:
    CREATE TABLE     t_1
    (     c_a     VARCHAR2(1)
    ,     c_b     NUMBER(2)
    ,     c_c     DATE
    );
    
    INSERT INTO     t_1
    VALUES('A',1,SYSDATE);
    INSERT INTO     t_1
    VALUES('A',2,SYSDATE+1);
    INSERT INTO     t_1
    VALUES('A',3,SYSDATE+2);
    INSERT INTO     t_1
    VALUES('A',4,SYSDATE+3);
    INSERT INTO     t_1
    VALUES('B',3,SYSDATE+6);
    INSERT INTO     t_1
    VALUES('B',4,SYSDATE+7);
    INSERT INTO     t_1
    VALUES('B',5,SYSDATE+8);
    I have the following query, which lets me select the ikram value that corresponds to the minimum value of c_b grouped by are. In other words, my goal is: for each value in are, I want the ikram value that corresponds to the minimum value of c_b.
    SELECT     t1.c_a
    ,     t1.c_c
    FROM     t_1 t1
    ,     (
         SELECT      c_a
         ,      MIN(c_b)     AS min_c_b
         FROM      t_1
         GROUP BY c_a
         ) t2
    WHERE     t1.c_a     = t2.c_a
    AND     t1.c_b     = t2.min_c_b
    ;
    This query works, but I wonder if there is a better way to do it. Something without a subquery? I can't get to what anyone else... It's just a bit tedious with my real data, as there are probably 10 columns of data instead of 3 has. (1 single minimum value but still).

    Use the KEEP FIRST / LAST function, grouping, that is to say:

    with t_1 as (select 'A' c_a, 1 c_b, sysdate c_c from dual union all
                 select 'A' c_a, 2 c_b, sysdate + 1 c_c from dual union all
                 select 'A' c_a, 3 c_b, sysdate + 2 c_c from dual union all
                 select 'A' c_a, 4 c_b, sysdate + 3 c_c from dual union all
                 select 'B' c_a, 3 c_b, sysdate + 6 c_c from dual union all
                 select 'B' c_a, 4 c_b, sysdate + 7 c_c from dual union all
                 select 'B' c_a, 5 c_b, sysdate + 8 c_c from dual)
    -- end of mimicking your t_1 table, see SQL below:
    select c_a, min(c_c) keep (dense_rank first order by c_b) c_c
    from   t_1
    group by c_a;
    
    C_A C_C
    --- -------------------
    A   21/07/2011 16:41:46
    B   27/07/2011 16:41:46
    

    NB. the min (ç_ç) is to choose what the lowest value of the ikram should there be more than one row returned for the first c_b. You can max (ç_ç) instead, according to your needs. (If are, c_b is unique, you can use either.)

    How big are your real matrices? How do you measure the speed? How fast is now and how fast should it be?

    In all cases, you can do it with a single loop, for example as an attachment.

    I guess there is the clause does not. You check against dtc_rule_item, I guess that is dtc_rule_item_lock.

  • Any way to export several columns in the links Panel?

    This was posted on the InDesign forum, suggested that there could be a script that could achieve this?

    Work on a manual with hundreds of illustrations. Each chapter has up to 100.  Need to get more than one column of data (file name and # it appears on the page) exported from the links Panel (in a sorted order) so they can be recessed into a spreadsheet. I use TextWrangler which will clear out all the names of files in a folder, but it sorts alphabetically and I really want them sort by Page numbers where they appear.

    This script creates a CSV file on the desktop that you can import into Excel. The name of the file is the same as the name of the indesign document active.

    var scriptName = "Generate list of links";
    if (app.documents.length == 0) ErrorExit("No documents are open. Please open a document and try again.");
    
    var page, allGraphics, graphic;
    var text = "File name;Page\r";
    var doc = app.activeDocument;
    
    for (var i = 0; i < doc.pages.length; i++) {
         page = doc.pages[i];
         allGraphics = page.allGraphics;
         for (var k = 0; k < allGraphics.length; k++) {
              graphic = allGraphics[k];
              if (graphic.itemLink != null) {
                   text += graphic.itemLink.name + ";" + page.name +"\r";
              }
         }
    }
    
    WriteToFile(text);
    
    //-------------------------------------- FUNCTIONS ---------------------------------------------
    function WriteToFile(text) {

  • Bindings.Select does not work with the primitive properties like string etc?

    My code works when I use a < String > ObjectProperty, this however does not work when I use a string instead.

    Don't know if this Bindings.select behavior is a bug or expected.

    The NBS are:

    The impression is:

    ObjectProperty < String >--> < String > ObjectProperty: abc

    String-> string: null

    String-> < String > ObjectProperty: null

    I expect all cases to print 'abc' good

    EDIT: Sorry for the horrible formatting. Can't seem to understand how to properly insert empty lines.

    Read the fine print in http://docs.oracle.com/javafx/2/api/javafx/beans/binding/Bindings.html#select(javafx.beans.value.ObservableValue, java.lang.String...)

    All classes and properties used in an affair of selection must be public.

    If you do your commentProperty, getProperty (and setProperty, although I suppose it doesn't matter) methods in public class has, it works as expected.

  • Select several CSS classes simultaneously (was: how to select multiple css rules at the same time?)

    Hello!

    I have Dreamweaver 8

    I tried to select several css rules at the same time create a css stylesheet, but I don't know how to do it!

    This man do in this video at 03:00

    http://www.YouTube.com/watch?v=ZbQ3GTFC-O0

    Thank you!

    DW8 does not support the selection of several classes in the properties panel.  I'm sure that this feature appeared in the exit of the CS6.  Unless you upgrade to CC or CS6, you must do this manually in your code.

  • Is it possible to select only one column of a table for the redaction?

    Hi, converted a Word doc with a table in PDF format.  You will need to write a single column of the table.

    Is it possible to select only one column for the redaction?  When we select and drag downwards, it selects the other columns in the following lines.

    With the help of Acrobat X Pro.  Any help is appreciated.

    Hold down the CTRL key and drag a selection.
