update of the clause... help

Hello

again we here is... problems with the update statement, I hope that someone will take some time and try to help me solve this problem.

I have the following table:

[code]

create the table ozn_test

(

Identification number,

Number value,

date of entry_date

);

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.01.2002','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.10.2002','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.04.2003','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.05.2003','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.01.2005','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.01.2006','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.01.2007','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.01.2007','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('01.05.2008','dd.mm.yyyy'));

insert into ozn_test (id, value, entry_date) values (null, 1181, to_date('8.11.2013','dd.mm.yyyy'));

[/ code]

Now what I want to do is update the table ID field ozn_test so that it will contain next

resoult:

[code]

ID VALUE ENTRY_DATE

1 1181 01.01.2002

1 1181 01.10.2002

2 1181 01.04.2003

2 1181 01.05.2003

3 1181 01.01.2005

4 1181 01.01.2006

5 1181 01.01.2007

5 1181 01.01.2007

6 1181 01.05.2008

7 1181 08.11.2013

[/ code]

As you can see I need set the same number to each line that has the same VALUE in the same YEAR of ENTRY_DATE or

increment this number if there is a line with another year.

If its not clear, please let me know.

Thank you for your comments!

or if you really want to use update

setting a day ozn_test set id =

(

Select the id of

(

Select dense_rank() (order of development, to_char (entry_date, 'YYYY')) id, rowid rid

of ozn_test

) t

where

t.RID = ozn_test.rowid

)

  • How to replace "apply downloaded update now" with "Check for Updates" in the menu help when the update fails because the downloaded update files are missing but the "Ready to install update" window keeps appearing?

    Question

    I have another type of problem with Firefox

    Description

    Window "Ready to Install" Firefox "Software Update" appeared. The folder "C:\Program Files\Mozilla Firefox\updates\0" contained the files update.mar, update.status and update.version. Each of the 3 files have been deleted. The next time that Firefox has been started, no update occurred because update files were missing. In the Menu bar, clicking Help showed in the menu drop-down that "apply downloaded update now" was always on the list. By clicking on "Apply downloaded update now" open "Software Update" window "Ready to install update", so that Firefox still considers that the update files exist, but they do not. In the window "Software Update", by clicking on "Restart Firefox" restart of Firefox, but once again it there's no update, and remains "apply downloaded update now" on the Help menu. How can "Apply downloaded update now" be replaced by "Check for Updates" so the update files can be downloaded?

    Version of Firefox

    Operating system

    Windows XP

    You can manually reset the software update feature by closing Firefox and remove the file "updates" (which seems you have done) and the two files "active - update.xml" and "updates.xml" - these are in the installation (C:\Program Files\Mozilla Firefox) directory or in the profile folder (C:\Documents and Settings\nom_utilisateur\Application Data\Mozilla\Firefox\Profiles\something.default).

    If it does not, see our KB article How to resolve the failure of the update of Firefox update error message - the section of 'last resort' can be useful, or or read this article from MozillaZine KB, software update.

  • Insert/update of the XML help merge and to generate the sequence number

    Hello

    I'm working on Oracle 11 g.

    I have a doubt with loading XML.
    I get an xml and I need to insert or update data in a table. What I can accomplish by using the MERGE statement.
    But there is a column in A table, I need to fill with a sequence number, based on the data sent in the xml file.
    The XML does not send the data in this column.
    And I have to make sure that sequence is created according to the order in which the records are present in xml.
    For example the MERGER is insert five rows and update two lines and insert again 3 rows of xml in table A. The sequence number must be created in the same order for the column in the table.
    Also for every new XML, the sequence starts with 1 and ends with the number of records in the xml file. I can't create a sequence and use the seq.nextval.

    Please let me know, there is a way to achieve this.

    Thank you!

    Hello

    As a result of your previous thread: {: identifier of the thread = 2403469}

    You can use the clause for ORDINALITE in XMLTable to generate the necessary sequence:

    MERGE INTO target_table t
    USING (
      SELECT x.seq_num, x.pk_id, x.col1, x.col2, ...
      FROM XMLTable(
             '/root/record'
             passing my_xml_doc
             columns seq_num FOR ORDINALITY
                   , pk_id   number       path 'ID'
                   , col1    varchar2(30) path 'COL1'
                   , col2    varchar2(30) path 'COL2'
                   , ...
           ) x
    ) src
    ON ( t.pk_id = src.pk_id )
    WHEN MATCHED THEN UPDATE
     SET t.seq_num = src.seq_num
       , t.col1 = src.col1
       , t.col2 = src.col2
       , ...
    WHEN NOT MATCHED THEN INSERT

    In fact, to be a model for a PHP page. DWT.php. If rename the
    model in the site manager is not update that built pages
    model, then you can do it with the find and replace. Site backup
    pages first. Then do a site-wide find and replace it.

    Search for /Templates/TemplateName.dwt

    Replaced by /Templates/TemplateName.dwt.php

    After that, you may have to re-create the site cache.

  • Help with the clause of "default".

    Hi all

    I have a scenario where there is a table with 75 columns. out of the 75 columns, 30 are varchar and 30 are digital. The remaining columns are other types of data when creating the table, that I forgot to mention the default values to varchar and numeric columns.

    Now, approximately 20,000 records are inserted into the table where some records contain NULL varchar and numeric. Now, I want to replace the null with varchar values and digital default values respectively.

    I can change the columns by adding the clause by default now and update the lines of NULL for the default values accordingly. But this process could be very heavy.

    Is there a better way to do this. Please help me.

    Thanks in advance,
    Rambeau

    I want to know that is it possible to set the default values for all columns of type varchar, both using a single SQL statement. Then you can update all the values NULL with default values.

    You are looking for something like this?

    SQL> create table t (empno default 1, ename default 'x') as select cast(null as integer) empno, cast(null as varchar2(10)) ename  from emp where rownum <= 4

    Table created.
    
    SQL> select * from  t
    /
         EMPNO ENAME
    ---------- ----------
    
    4 rows selected.
    
    SQL> update t set empno = default, ename=default

    4 rows updated.
