What is the function on the 50G will return all variables used in algebraic exoression list?

Example entry:

(x + y) ^ z / x

output:

{x y z}

Hello Chris_Chen,

the command "LNAME" does what you want, but you get the result as a vector, not a list.

For example: ' Q ^ 2 - SIN (XT)'-> [Q XT]

But this can be easily converted into a list: < < OBJ-> OBJ-> MENU-> LIST > >

  • Function to retrieve all the days of the previous month.

    Hello

    Yes, it's a monthly report, I received the task at hand.

    So, all I need is every day of the previous month (even if there is no data for that day)

    I was instructed to use the following code, but it does not return a value any:
    DECLARE
       CURSOR CUR_LAST_DAY IS
          SELECT TO_CHAR (LAST_DAY (ADD_MONTHS (SYSDATE, -1) ), 'DD')
            FROM DUAL;
     
       VVA_LAST_DAY   VARCHAR2 (2);
       --
       VNU_JOUR       NUMBER       := 0;
    BEGIN
       OPEN CUR_LAST_DAY;
     
       FETCH CUR_LAST_DAY
        INTO VVA_LAST_DAY;
     
       CLOSE CUR_LAST_DAY;
     
       WHILE VNU_JOUR <= TO_NUMBER (VVA_LAST_DAY) - 1
       LOOP
          VNU_JOUR := VNU_JOUR + 1;
       END LOOP;
    END;
    --CLOSE CUR_LAST_DAY
    --DEALLOCATE CUR_LAST_DAY
    -----
    On the other end, I developed this code:
    SELECT TO_CHAR(SYSDATE,'dd')
    FROM DUAL
    WHERE TO_CHAR(SYSDATE,'dd') >= to_char(to_date(to_char(ADD_MONTHS(SYSDATE, -1),'yyyy-mm')||'-01'),'yyyy-mm-dd')
    AND TO_CHAR(SYSDATE,'dd') < to_char(LAST_DAY(to_date(to_date(to_char(ADD_MONTHS(SYSDATE, -1),'yyyy-mm')||'-01'),'yyyy-mm-dd')));
    Which returns a null value. :(

    Concerning

    Hello
    You want to retrieve whole days of the month last query... So here's...

    SELECT
    TO_DATE(LEVEL||'-'||TO_CHAR(ADD_MONTHS(SYSDATE,-1),'MON-YY'),'DD-MON-YY') COMP_DATE,
    TO_CHAR(TO_DATE(LEVEL||'-'||TO_CHAR(ADD_MONTHS(SYSDATE,-1),'MON-YY'),'DD-MON-YY'),'DD') ONLY_DD,
    TO_CHAR(TO_DATE(LEVEL||'-'||TO_CHAR(ADD_MONTHS(SYSDATE,-1),'MON-YY'),'DD-MON-YY'),'MM') ONLY_MM,
    TO_CHAR(TO_DATE(LEVEL||'-'||TO_CHAR(ADD_MONTHS(SYSDATE,-1),'MON-YY'),'DD-MON-YY'),'YY') ONLY_YY
    FROM DUAL
    CONNECT BY LEVEL <= TO_NUMBER(TO_CHAR(LAST_DAY(ADD_MONTHS(SYSDATE,-1)),'DD'))
    

    I'm not at the machine database so not tested.

    But one thing do not forget that this forum only for reports, it is a separate SQL and pl/sql instance.

  • How to filter data according to internal application and in case if returns nothing outside the query must return all the lines

    create table ab (a number, b varchar2 (20));

    Insert into ab

    Select rownum, rownum. "" sample "

    of the double

    connect by level < = 10

    create table bc (a number, b varchar2 (20));

    Insert into BC.

    Select rownum + 1, rownum + 1 | "" sample "

    of the double

    connect by level < = 10

    Select * AB

    where b in (select b BC where b = "2sample")

    This query will return me 1 row, but there are cases where the value of the parameter b is null

    and that it should return all rows in the table

    as

    Select * AB

    where b in (select b BC where b = "2sample")

    which return specific values, but I want to change in a way when the inner query returns nothing then outer query should return all the lines and works as

    Select * AB;

    Is it possible to put in a single query

    Hello

    You seem to ask for different things.  You want all the lines AB when

    1. The parameter ("2sample' in the example) is NULL, or when
    2. There is no corresponding row in the 2 tables (which could happen even if the parameter is not NULL)

    ?

    Assuming you want the option 2, here's one way:

    WITH got_rnk AS

    (

    SELECT ab.*

    DENSE_RANK () (ORDER IN CASE

    WHEN b (IN)

    SELECT b

    BC.

    WHERE b = "2sample" - parameter

    )

    THEN "A".

    OF ANOTHER 'B '.

    END

    ) AS rnk

    AB

    )

    SELECT a, b

    OF got_rnk

    WHERE rnk = 1

    ;

    This does not assume b is unique in each table.

    What burning CDs in Windows Media music system prepares all the files listed.  When the system starts writing the files on the disc it gets through about 4 songs and then goes to finalize the disc and ejects the disc.  The disk does not appear to have anything on it.  Can I do anything locally to solve the problem?

    My system is XP.

    I burned the disc a lot in the past

    There has been no major changes to the system

    The files I am to burn to the disc are previously ripped files on the disk hard, some of them were burned on another drive before.

    I tried to slow down the burn speed, but that did not work.

    CD burning problem

    Hello

    • You receive an error message when burning CDs?
    • What were the changes made before the issue started?
    To resolve this problem, do one or more of the following and then try again:

    a. Verify that the CD burner is properly connected.

    b. clean the disc and verify that it is not damaged.

    c. try a different brand of blank discs.

    d. If another program is currently burning files on the CD, wait until the burning process is completed.

    e. Quit other programs that may be using the CD burner.

    f. restart Windows Media Player.

    g. restart your computer.

    h. use the Windows error-checking tool to find system errors of files with bad sectors on your hard drive. For more information about the error-checking tool, see Windows Help and Support.

    1. the first thing to do is to make sure that the computer is completely virus/malware-free. Googling around this error produced quite a few links where the posters were or had been infected with Spyware Protect 2009 rogue.

    Once the scanning is complete (do not skip the preparatory stages no more), if the problem persists:

    2. double-click on my computer, right-click the icon for your hard drive, click left to get its properties. If you see options to set Quota management make sure that they are disabled.

    3. in the case - BUT ONLY AFTER YOU ARE sure THAT THE MACHINE IS MALWARE/VIRUS-FREE - copy the lines between asterisks (not including the asterisks) below and paste it into Notepad. Save as undopolicy.reg somewhere, you will find. And then double-click the .reg file, that you have just made to melt in your registry. I hope that this will take care of the issue.

  • Function to move all the dates for the previous Monday

    Here's what I have:

    create or replace
    FUNCTION ToPreviousMonday
    (DATE_FIELD IN date)
    Date of RETURN
    AS
    BEGIN
    IF TO_DATE (DATE_FIELD, 'DAY') = 'SUN' THEN (DATE_FIELD)-6;
    Of ANOTHER trunc (DATE_FIELD, 'd.') + 1;
    END IF;
    END ToPreviousMonday;

    Don't compile.

    Basically, what I want to accomplish is in a SELECT statement, say something like (SELECT ToPreviousMonday (MyDateField) FROM MaTable) and cause the data back as the date of the previous Monday. NLS_TERRITORY is and will be for all the sessions going to Sunday as the day of the week 1.

    Pointers?

    Use:

    TRUNC (DATE_FIELD, 'IW')

    IW means ISO week which starts always on Monday regardless of NLS.

  • return all the possible model of a string

    Hi all

    I would like to return all possible models from a given string, for example when a string is "ABC", I should get

    ABC
    ADJUSTED COST BASE
    TRAY
    BCA
    CAB
    CBA

    as well as

    AAA
    BBB
    CCC
    ABB
    VAC
    BAA
    BCC
    CAA
    CBB


    I could write this:

    Select permut
    from (select replace (SYS_CONNECT_BY_PATH (e, ',') ',') permut)
    of (SUBSTR ('ABC', level 1) select e)
    of the double
    connect by level < = length ('ABC'))
    connect e nocycle! e = prior)
    where length (permut) = 3


    but the output is just:

    ABC
    ADJUSTED COST BASE
    TRAY
    BCA
    CAB
    CBA


    any ideas? for ora10g or 11g sql/plsql

    Thank you

    This is similar to the solution of Frank, but somewhat simpler:

    with indata as (
      select 'ABC' txt from dual
    ), chrs AS (
      select substr(txt,level,1) chr
      FROM indata
      CONNECT BY level <= LENGTH(txt)
    )
    select replace(sys_connect_by_path(chr, '/'), '/', '') permut from chrs
    where connect_by_isleaf = 1
    connect by level <= (select length(txt) from indata);
    

    [Edit: I guess the main difference is that I don't see the need to SEPARATE.]

    If you don't have the appeal of the form in a procedure in a library?

    One way would be to update your code with JDAPI to substitute call_form instruction in all pl/sql in modules (and I'd do it for a procedure of Central Library).

  • {module_faqresults} returns all the FAQS on the opening page (includes screenshots)

    Hello, I am going through a book about Business Catalyst and it was written before this new version, so things are not as clear. The book does not show what is currently happening with module FAQ Business Catalyst.

    When I include the FAQ Module Business Catalyst search engine, it adds the {module_faqresults} automatically and when you view the page in a browser instead of wait for a search term be added to the input box and searched, the default page to all the frequently asked questions in the database.

    So if you search for a term he will return only the elements of the search term. How can you get to not display all of the FAQS as soon as the page opens and wait until someone actually searching for something and then return these results?

    I've included several pictures to explain what I mean.

  • Returns all the duplicate values in object lookup (PHP, drop-down list)

    Hi, I have a PHP page I designed as a search page. I have a number of drop-down lists that get their dynamic values from the fields in a MySQL database.

    At present, if there are any entries that have duplicate values in a certain area, they are all listed, in the order of the index database. For example:

    City:

    Derby

    Stoke

    Stafford

    Stoke

    Derby

    Derby

    Stoke

    etc...

    Now, I want to do is be able to show all results for a given city. In the find what drop-down list box, I would than each of the cities to appear only once rather than every time it is registered. included in this, I would like the page of results to then display ALL results that match this search criteria.

    Thus, in the example above, "Derby" appears only once, but when the user has selected 'Derby', it would return all three results in the results page.

    My results page is built on a dynamic form, so I am confident that the results page would make it according to the needs. However, how can I get the drop-down list box to ask him?

    > 'SELECT DISTINCT table1.champ1, table1.champ2, table1.champ3 FROM Table1 ";

    Duplicate rows to remove the DISTINCT keyword strength SQL. In other words, that it will only return the unique combinations of fields in your selection list. If you examine your results set, you will see that each line is separate, although there may be duplicates in a particular area. Because you want to populate a drop-down list, you must include a field in your select list only, otherwise you get of the dupes.
