  Now, I have to update Delhi and Hyderabad Hyderabad with Delhi.

  How to do this?

  Hi Indi,

  (1) why do you want what it? Requirements of companies?

  (2) how much these values you want to reverse? Is it only "Delhi" and "Hyderabad", or there is a list, or other logic?

  Update your_table

  Set city = decode (lower (city), 'delhi', 'Hyderabad', 'hyderabad', 'Delhi')

  where lower (city) ('Delhi', 'hyderabad');

  Does that help?

• Matrix of distances: selection of values with the number of the column as a variable

  Hi all
  
  You wonder if SQL can do natively, let's go.
  
  I have a static table with the same amount of rows and columns, that changes forever; It represents the distances between locations (e.g. countries).
  It's basically a distance matrix (you can find a good example on Wikipedia ).
  
  My SQL statement must extract the distances of this matrix, based on the IDS of countries located in another table.
  Select a field is simple:
  
  SELECT * from cdistances where countryid =
  (select countryid from countries where upper (country) = upper (& getcountry));
  
  When I run the present, I get a line of all distances to all countries of the country I go when asked. But I would limit the outcome of a country of destination that I entered.
  
  Of course, a CASE statement would solve this nicely, but since we are talking more than 200 countries, which will become unmanageable.
  
  Another method that I approached is to use a variable as a column, as below:
  
  SELECT & getdestination of cdistances where countryid =
  (select countryid from countries where upper (country) = upper (& getcountry));
  
  It works well when I get directly the column identifier (manually from the keyboard) but I would like to automate even further.
  My names of columns in the matrix of distances are named as follows:
  countries1, countries2, countries3... country200 - where the number ID the real country, preceded by the constant string 'country '.
  So I tried to define a variable as a concat between 'country' and another variable:
  def getd2 = concat ("D2C", & testcountryid);
  Of course, it does not; the output of the script is:
  
  old: def getd2 = concat ('country', & testcountryid)
  New: def getd2 = concat ("country", 12)
  
  where I expected to be 'country12.
  
  I'm so little loss of thoughts. Maybe I'm pushing my train of thought in the wrong way, so I guess the general question would be: how to select a specific column of a table based on information outside the SQL statement dynamically?

  Hello

  I'm still confused.
  Is your table called chessking or testdistances, or you have 2 separate tables?

  I'm guessing that your single table is testdistances, and you want to pass a list of countryids, such as that of 3.1 to a query and get results as follows:

  `COUNTRYID  DISTANCE3  DISTANCE1
  ---------- ---------- ----------
           1         18         15
           3         13          1
  

  If so:

  DEFINE     country_list = "3,1"
  
  -- Preliminary Query, to set column_list
  COLUMN     column_list_col     NEW_VALUE column_list
  
  SELECT     'distance' || REPLACE ( '&country_list'
                             , ','
                       , ',distance'
                       )          AS column_list_col
  FROM    dual;
  
  -- Main Query
  SELECT     countryid
  ,     &column_list
  FROM     testdistances
  WHERE     countryid     IN (&country_list)
  ;
  

  Sorry, I'm out of time now. I'll explain more in a few hours.

• Add a table with the number of lines and columns JS

  Hello

  Simple question: what is the syntax for adding a table with a specified number of rows and columns? I don't get it. (I don't know how to add them later, but I want to do when I create the table). Here is the entry in the ESTK:

  Tables.Add (to: LocationOptions, reference: all, withProperties: Object): array

  Creates a new table.

  (optional): Data Type: LocationOptions, by default: LocationOptions.UNKNOWN
  The location of the new table to the object within the container object or reference. (Optional)

  Reference: Data Type: no
  The reference object. Note: Required when the value specifies before or after. Can accept: Table, XmlStory, XMLElement, TextFrame, text, character, Word, line, paragraph, TextColumn, PointInsertion, story, cell or TextStyleRange. (Optional)

  withProperties: Data Type: object
  Initial values for the properties of the new Table (optional)

  Thank you

  Ariel

  After much experimentation, I found this works:

  t = app.selection [0].tables.add (LocationOptions.AT_BEGINNING, undefined, {columnCount:2, headerRowCount:1, bodyRowCount:5, footerRowCount:3});})

• CRUD for tables with large number of columns

  Hello

  I work for a government agency in Colombia, and we do a poll with about 1200 variables. Our database model has few paintings, but they have a large number of columns. Our Oracle 11 g database is, and we do not use Oracle APEX. I've read about APEX and it seems to be useful to generate quick forms and reports. However, I would like to know if it is possible to generate CRUD for tables with many columns, and that would be the best way to do it.

  Thanks in advance.

  Carlos.

  With the help of 250 point on a single page is actually really bad for the user experience. I would probably be it cut into pieces and using several pages to guide the customer through it as a workflow.

  You could also add some pop-up windows which includes some elements of your table, just saved on other pages. But I probably don't like that.

• How to update the table with the number management

  Now, I wanted to update the table such that all ID columns are updated with running number.
  
  Each ID columns should get incremented so that, for Country_ID column corresponding to "India" If country_id is 1, that there must be one for all the lines with the name as "India". Likewise for "Australia".
  
  In the case of State, she also has the same logic with numbers repeated until the very name of the State comes.
  
  For the city, it of course will hold separate ID only because the name of the city will not get duplicated.
  
  This update must be done in the normal way using simple SQL such as no PLSQL don't like looping, etc... is involved.
  
  Here are the contents of the table, and that's how the table should be updated,
  

  COUNTRY_ID     COUNTRY_CODE     COUNTRY_NAME     STATE_ID     STATE_CODE     STATE_NAME     CITY_ID     CITY_CODE     CITY_NAME

• Insert the problem using a SELECT table with an index by TRUNC function

  I came across this problem when you try to insert a select query, select returns the correct results, but when you try to insert the results into a table, the results are different. I found a work around by forcing a selection order, but surely this is a bug in Oracle as how the value of select statements may differ from the insert?
  
  Platform: Windows Server 2008 R2
  11.2.3 Oracle Enterprise Edition
  (I've not tried to reproduce this on other versions)
  
  Here are the scripts to create the two tables and the data source:

  CREATE TABLE source_data
  (
    ID                 NUMBER(2),
    COUNT_DATE       DATE
  );
  
  CREATE INDEX IN_SOURCE_DATA ON SOURCE_DATA (TRUNC(count_date, 'MM'));
  
  INSERT INTO source_data VALUES (1, TO_DATE('20120101', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120102', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120103', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120201', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120202', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120203', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120301', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120302', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120303', 'YYYYMMDD'));
  
  CREATE TABLE result_data
  (
    ID                 NUMBER(2),
    COUNT_DATE       DATE
  );

  Now, execute the select statement:

  SELECT id, TRUNC(count_date, 'MM')
  FROM source_data
  GROUP BY id, TRUNC(count_date, 'MM')

  You should get the following:

  1     2012/02/01
  1     2012/03/01
  1     2012/01/01

  Now insert in the table of results:

  INSERT INTO result_data
  SELECT id, TRUNC(count_date, 'MM')
  FROM source_data
  GROUP BY id, TRUNC(count_date, 'MM');

  Select the table, and you get:

  1     2012/03/01
  1     2012/03/01
  1     2012/03/01

  The most recent month is repeated for each line.
  
  Truncate your table and insert the following statement and results should now be correct:

  INSERT INTO result_data
  SELECT id, TRUNC(count_date, 'MM')
  FROM source_data
  GROUP BY id, TRUNC(count_date, 'MM')
  ORDER BY 1, 2;

  If someone has encountered this problem before, could you please let me know, I don't see what I make a mistake because the selection results are correct, they should not be different from what is being inserted.

  Most likely a bug in 11.2.0.3. I can reproduce on Red Hat Linux and AIX.

  You can perform a search on MOS to see if this is a known bug (very likely), if not then you have a pretty simple test box to open a SR with.

• How to move a table (with the UDT as a column) to a different schema

  I have a table that has a column of user-defined type. There is a requirement to an another schema of this table as well as the UDT. I tried to create the table as, the problem is that it uses the DFU of the original schema. Is there a way to do this?

  Ex:

  User 1:

  CREATE TYPE employee_t AS OBJECT

  (employee_id NUMBER

  , employee_name VARCHAR2 (30)

  Number of salary

  dept_id NUMBER);

  Department of CREATE TABLE

  (emp employee_t

  , Bishop varchar2 (40)

  number of dept_id

  (, dept_name varchar2 (30));

  In the example above, department table has a column called emp that is UDT.

  Now on User2, if I do the following

  Create service table in select * from user1.department. Table will be created as follows. In fact I want EMPLOYEE_T also to be moved to User2.

  Name                                      Null?    Type

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

  EMP                                                USER1. EMPLOYEE_T

  BISHOP VARCHAR2 (40)

  NUMBER OF DEPT_ID

  DEPT_NAME VARCHAR2 (30)

  You can use expdp and impdp - but you must include the type explicitly in your dump command, since it isn't included automatically: http://dbaharrison.blogspot.de/2013/05/expdp-of-just-table-and-type-dependents.html.

• Impossible to delete the partitions of a table with the number of rows is zero

  Hi all
  
  I want to delete all partitions on all the tables in a schema having the number of lines equal to zero.
  
  I use the queries below to get a solution.
  
  Select 'EDIT '. '' || 'TABLE ' | TABLE_NAME | 'DROP '. 'PARTITION | Nom_partition from dba_tab_partitions where TABLE_OWNER = "xyz";
  
  Select count (*) in the table table_name partition (nom_partition).
  
  Edited by: 887563 October 17, 2011 13:39

  If you trust your statistics, you can simply use the stat num_rows in dba_tab_partitions:

  select *
  from dba_tab_partitions
  where table_owner = 'MY_SCHEMA'
  and num_rows = 0;
  

  But I think what you try to get some code like this:

  declare
    v_rows number;
    v_statement varchar2(500);
  begin
    for c in (select *
              from dba_tab_partitions
              where table_owner = 'MY_SCHEMA') loop
      v_statement := 'select count(*) from '||c.table_name||
                     ' partition ('||c.partition_name||') where rownum=1';
      --dbms_output.put_line(v_statement);  --for debugging
      execute immediate(v_statement)
      into v_rows;
      --dbms_output.put_line(c.table_name||' '||c.partition_name||' '||v_rows);  --for debugging
      if v_rows = 0 then
        v_statement := 'ALTER TABLE '||c.TABLE_NAME||' DROP PARTITION ' || c.PARTITION_NAME;
        dbms_output.put_line(v_statement); --shows the drop statements
        --execute immediate(v_statement); --remove comment to execute
      end if;
    end loop;
  end;
  

• With the help of inplace column number of the column name in the SQL Select statement

  You can extract the names of the columns for user_tab_columns
  with

  SELECT Column_name

• create table as a table with nested column type

  On my Oracle DB (11.1), I have a table with a nested as a column type (and it is a partitioned table).
  Now I need to copy partitions in a second table, and I use swap partition for it (with a table that is not partitioned as a table in step).
  
  But there is a problem, because as the ordinary as sql ddl:

  create table table1_stage as select * from table1 where 1=2;

  does not work when there is a table nested within a column type.
  Is it possible easy to copy its structure (and to create the table that is not partitioned, so I suppose that no dbms_metadata package would help)?
  
  
  Kind regards...

• Not how to show a part of online data in a table in another table with even no column?

  I need to display the data from certain rows in a table in another table with the same numbers of columns and main table must be disabled. Could someone advice how to do this?    Data in the table are from the microprocessor and is intended the user can see and edit only some data.

  If someone can show me some advice, it will be a great help.

  Kind regards

  Annemariehoeven

  Disable a table: SetInputMode (panelHandle, controlID, 0);  ('1' to re - activate).

  Hide a table: SetCtrlAttribute (panelHandle, controlID, ATTR_VISIBLE, 0); ('1' to show it again).

  These commands are valid for each type of control.

  To extract values from the table, you can just use GetTableCellVal or GetTableCellRangeVals: If the range of cells has the same data type, you can use the second command which is faster; If the cells are different (for example digital and channels) you must solve each of them individually. The use of the Clipboard doesn't have this limitation.

• How update the relational table with XML data?

  I get XML messages that include a bunch of data items to be updated in a table. An arbitrary subset of rows is updated for each message received.
  
  The output of the following example is correct, but the use of the intermediate table that bothers me. The temporary table can be eliminated somehow? Or is the most reasonable way to loop just explicitly and parse the XML message and then update each row separately?
  
  I'm under 11.2.0.1.0.
  

  create table otn9test (
    id number not null primary key,
    data xmltype
  );
  
  insert into otn9test values (1, xmltype('<data>default for 1</data>'));
  insert into otn9test values (2, xmltype('<data>default for 2</data>'));
  insert into otn9test values (3, xmltype('<data>default for 3</data>'));
  
  create table otn9input (
    id number,
    data xmltype
  );
  
  column data format a30
  
  declare
    updata constant xmltype := xmltype('<root>
    <item>
      <id>1</id>
      <data>Id 1 updated.</data>
    </item>
    <item>
      <id>3</id>
      <data>Id 3 updated.</data>
    </item>
    <item>
      <id>4</id>
      <data>Id 4 updated.</data>
    </item>
  </root>');
  
  begin
    insert into otn9input
      select * from
      xmltable('/root/item' passing updata
            columns
            id number path 'id',
            data xmltype path 'data');
  
    update otn9test t set data = (
      select data from otn9input i
      where t.id = i.id
    ) where t.id in (select id from otn9input);
  
    commit;
  end;
  /
  
  select * from otn9input;
  
  /*
       ID DATA
  ---------- ------------------------------
        1 <data>Id 1 updated.</data>
        3 <data>Id 3 updated.</data>
        4 <data>Id 4 updated.</data>
  */
  
  select * from otn9test;
  
  /*
       ID DATA
  ---------- ------------------------------
        1 <data>Id 1 updated.</data>
        2 <data>default for 2</data>
        3 <data>Id 3 updated.</data>
  */
  
  drop table otn9input;
  drop table otn9test;

  The temporary table can be eliminated somehow?

  You can do it with the MERGER:

  merge into otn9test t
  using (
    select id, data
    from xmltable('/root/item' passing updata
          columns
            id   number  path 'id',
            data xmltype path 'data'
         )
  ) x
  on ( t.id = x.id )
  when matched then update
   set t.data = x.data
  ;
  

  However, if you are looking for performance on large data sets, I think that the best is to use an intermediate table of XMLType (binary storage) to maintain the XML instance.

  create table otn9input of xmltype
  xmltype store as securefile binary xml;
  
  insert into otn9input values(
  xmltype('
    
      1
      Id 1 updated.
    
    
      3
      Id 3 updated.
    
    
      4
      Id 4 updated.
    
  ')
  );
  
  merge into otn9test t
  using (
  select id, data
  from otn9input,
       xmltable('/root/item' passing object_value
            columns
              id number path 'id',
              data xmltype path 'data'
       )
  ) x
  on ( t.id = x.id )
  when matched then update
   set t.data = x.data
  ;
  

  A structured XMLIndex could also help.
