• The value of xml type column in oracle database 11 g 2

  I have a table containing columns XMLtype as 'XML_TABLE (ID NUMBER, donnees_xml XMlTYPE).

  Then I insert a value such as

  INSERT INTO xml_table (1, XMLtype('<current>
        <city id="2643743" name="London">
          <coord lon="-0.13" lat="51.51"/>
          <country>GB</country>
          <sun rise="2015-03-04T06:38:20" set="2015-03-04T17:46:01"/>
        </city>
        <temperature value="280.71" min="280.15" max="281.15" unit="kelvin"/>
        <humidity value="77" unit="%"/>
        <pressure value="1029" unit="hPa"/>
      </current>'));
  

  
  

  Now, I want to ask about this table. I can easily choose 'country' with the following query

  select t.xml_data.extract('/current/city/country/text()').getStringVal() "XML Data"
  from xml_table t;
  

  But I can't select the value of the temperature by this query. Now how to select the value of the temperature of the table?

  EXTRACT, EXTRACTVALUE etc are deprecated in 11.2.

  Use instead the XQuery functions.

  If you need to retrieve several values, XMLTABLE will be good:

  SQL> alter session set nls_numeric_characters = ".,";
  
  Session altered.
  
  SQL>
  SQL> select x.*
    2  from xml_table t

    6         columns country     varchar2(10) path 'city/country'
    7               , temperature number       path 'temperature/@value'

• Web Forms: Deleting line based on the value of a specific column

  Hello
  
  I have an online form in which I want to apply delete missing on the ranks, but only on the value of the first column. So, if the first column is #missing I want the deleted row, even if the columns are given in it.
  
  Is it possible to do this?
  
  I'm on ver 11.1.2.2 Hyperion Planning
  
  Shehzad
  
  Published by: shehzad k on January 24, 2013 11:51

  Unfortunately, no. There is no way to add the delete line based SOLELY on the existence of a value in the first column. It would be nice to see some of the more advanced features "conditional delete", we en flies over to the planning of the entry forms.

  You can do the "clumsy" things with data validations where you gray - out ranks in view of the existence of a value in a particular cell, however while this might SUGGEST that the user should not enter data in a particular line, it would not PREVENT to do so.

  We have seen many improvements in form lately with the introduction of data validations. I hope the momentum continues.

• What SYS tables (not seen) contains the value NULL spec /not/ column definition?

  What SYS (or tables) store the value of a spec /not/ NULL columns? (It doesn't seem to be COL$)
  
  NOTE: This is NOT a trick question - although it seems to be.
  
  Test configuration:

  BANNER
  Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
  PL/SQL Release 11.2.0.1.0 - Production
  CORE     11.2.0.1.0     Production
  TNS for Linux: Version 11.2.0.1.0 - Production
  NLSRTL Version 11.2.0.1.0 - Production

  Test configuration:
  1. a table is created by SCOTT in the SCOTT schema with a NULLABLE column.
  
  2. a primary key constraint is added using only the NULLABLE column
  
  3. Requests for information on USER_TAB_COLS, ALL_TAB_COLS, DBA_TAB_COLS and SYS. COL$ see NOT NULL for the column NULLABLE
  as necessary for a primary key constraint. Views derive their data from the column of $ NULL the sys. Table of $ COL
  using

  'DECODE (SIGN (c.null$), -1, 'D', 0, 'Y', 'N'),

  and the table of $ COL shows a numerical value of '0' before you add the primary key and a value of "1" later.
  
  4. a query on the DDL metadata table shows the specification for column NULLABLE of origin involved.
  
  Question - where this original specification NULLABLE is stored?
  
  This question is based on a question asked by another user in this thread
  Columns becoming nullable after a fall of primary key?
  
  I created the following specially for that matter test case

  -- scott ensures table does not exist
  DROP TABLE tbl_test CASCADE CONSTRAINTS;
  
  -- scott creates a table
  CREATE TABLE tbl_test ( col_1 NUMBER,
  col_2 NUMBER NOT NULL);
  
  -- scott queries to check the the column nullable status
  SELECT table_name, column_name, nullable 
  FROM user_tab_cols
  WHERE table_name = 'TBL_TEST';
  
  -- TABLE_NAME | COLUMN_NAME | NULLABLE
  -- TBL_TEST   | COL_1       | Y 
  -- TBL_TEST   | COL_2       | N 
  
  -- Scott addes a primary key constraint using only the nullable column
  ALTER TABLE tbl_test ADD CONSTRAINT tbl_test_pk PRIMARY KEY(col_1);
  
  -- scott queries to check the the column nullable status
  SELECT table_name, column_name, nullable 
  FROM user_tab_cols
  WHERE table_name = 'TBL_TEST';
  
  TABLE_NAME,COLUMN_NAME,NULLABLE
  TBL_TEST,COL_1,N
  TBL_TEST,COL_2,N
  
  -- scott queries to get the table DDL
  select dbms_metadata.get_ddl('TABLE', 'TBL_TEST', 'SCOTT') FROM DUAL;
  
  DBMS_METADATA.GET_DDL('TABLE','TBL_TEST','SCOTT')
  
    CREATE TABLE "SCOTT"."TBL_TEST" 
     (     "COL_1" NUMBER,                   <------ where is this NULLABLE spec stored? 
       "COL_2" NUMBER NOT NULL ENABLE, 
        CONSTRAINT "TBL_TEST_PK" PRIMARY KEY ("COL_1")
    USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS NOCOMPRESS LOGGING
    TABLESPACE "USERS"  ENABLE
     ) SEGMENT CREATION DEFERRED 
    PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
    TABLESPACE "USERS" 

  The DOF shows that Oracle keeps the original spec NULLABLE for the column and uses it to generate the DDL orginal, even if there is a primary key on the table and the system views (and COL$) show the column non NULLABLE.
  
  So where is the original information NULLABLE actually stored?

  rp0428 wrote:
  What SYS (or tables) store the value of a spec /not/ NULL columns? (It doesn't seem to be COL$)

  I think that it becomes a bit messy depending on order of activity:

  You can see Col. .null$ is set to a non-zero when the desrcibe command displays the column as not null, but it can happen for two reasons:
  (a) user sets the column as not null - in which case you get a line in cdef$ with type # = 7
  (b) the user adds a primary key to table - in which case you get a line in cdef$ with type # = 2

  If you declare null AND add a primary key, you get two lines - that's why it is possible for Oracle to determine if he should remove the flag not null when you remove the primary key and also allows dbms_metadata show the create statement of table without a NOT NULL even when describe it the watch with a NOT NULL - dbms_metadata can respond to the presence of the type # = 2 and absence of the type # = 7.

  By the way: by a strange coincidence, it seems to me answering the previous post, three days before it was asked: http://jonathanlewis.wordpress.com/2012/04/19/drop-constraint/#comment-46140 (on the doubts, this isn't - it answers a different question on the removal of constraints).

• Need help with Javascript to get the value of standard report column

  Hi all
  
  Apex 3.1 version
  
  I have a query SQL (editable report) region where I need to do validations using a process of OnDemand and javascript. For this posting, I need to use the serial number and id of this same report line item. The function is called when the serial number is changed. I can get the serial number easily because it is a text field, however, the item id is a standard report column (which actually a text field or hidden gives me a checksum error, long story). How can I get the value of the standard report column to set the value of an element of the Application to use in my process of application as well as the serial number? Here is my code below.
  

  <script>
  
  function f_ValidateSerial(pThis)
  {
      
    // The row in the table
  
    var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
  
      //alert('Row is '+vRow);
  
  
    // Display the serial number
      //alert('The Serial Number is '+html_GetElement('f21_'+vRow).value);
  
    
   var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=ValidateSerial',0);
   get.add('F101_SERIAL_NUMBER',html_GetElement('f21_'+vRow).value);
   get.add('F101_INVENTORY_ITEM_ID',+html_GetElement(?????+vRow).value);   // Here's where I need to get the item id to set application item!!
   
   gReturn = get.get();
   
  if (gReturn)
      { 
        alert(gReturn);
      }
   
    if(gReturn)
      { 
        html_GetElement('f21_'+vRow).value = '';
      }
             
  }
  </script>

  Hello

  Ok

  Item ID is standard report column.
  If you enter this Expression HTML column

  #ITEM_ID#
  

  I guess that the substitution of column item Id is #ITEM_ID #.

  Now, you have hidden input form that is not submitted.
  Then in JavaScript

  get.add('F101_INVENTORY_ITEM_ID',+html_GetElement('item_id_'+Number(vRow)).value);

• find the value relative to another column

  Find the value column B in the column 'sparent. Let me explain the few cases:
  Suppose that we receive the 1000 kg of quantity for Jack, Jack then transferred this 1000 kg to Robin and Robin transferred once again this amount to Parkins and so on. A column named Type records the entry type, either it's a receipt or transfer operation. His entry would be recorded in my table like:
  
  QTY_ A_ B_ Type_
  Reception of 1000 Jack
  1000 jack Robin transfer
  Transfer of 1000 Robin Parkins
  
  So, with this information, you find the parent of Parkins, Jack, receipt of Type?

• ALTER Table of the default Oracle and the length of name of column Type

  Hi all
  
  I want to increase the length of the table names and the names of the columns in Oracle.
  
  By default, it is set like this:
  
  SQL > dba_tab_columns desc;
  
  TABLE_NAME NOT NULL VARCHAR2 (30)
  COLUMN_NAME NOT NULL VARCHAR2 (30)
  ...
  
  Is it possible to change the VARCHAR2 (30) to VARCHAR2 (100)?
  
  Published by: sukrandere on 12:21 10.Mar.2010

  Table names and column are all two identifiers
  According to the documentation, the maximum length of an identifier is 30 characters.
  It is hard coded in the database software and you can't change it.
  Or do you need to change.

  Comments: comments

  That's exactly what I get every time and I can't find a solution, I tried reading online resources and through the books I have, but I can not find the reason why, anyone who has ever met this before or have a link they could post.

  Note for this is when I click on the reply button, it will let respond me to the correct e-mail which was presented in the form, but the email field looks like I typed it above.

• concatenation error - when I use the value of the column of text in which the condition.

  Hello
  
  I'm creating Materialized view using a few columns from two tables and by obligation, I need to prepare a select statement with a where condition in another column. (new heading)
  
  I tried like below...
  
  create a materialized view HAND
  force refresh on demand
  as
  Select
  a.table_name,
  a.column_name,
  b.trial_name,
  ' Select * from ' | '. a.table_name |' where ' | a.column_name | ' = '|| b.trial_name | « ; » "QUERY".
  Of
  exp_csv_tB has,
  b exp_csv_tr;
  
  
  the value of name a.table is: monitoring_table
  a.column_name value is: study
  b.trial_name = fty777
  
  
  
  Materialized view created with an extra column, but it is not added "(codes) to the value of the text in which the condition.
  
  output I got is:
  
  Select * from monitoring_table where study = fty777;
  
  but
  
  I need output like
  
  Select * from monitoring_table where to study = "fty777";
  
  value of fty777 must be in the codes like "fty777". I read a few articles, but did not get this example.
  
  Help, please.

  You need to escape your quotes (double upward on quote)

  create materialized view MAIN
  refresh force on demand
  as
  select
  a.table_name,
  a.column_name,
  b.trial_name,
  'select * from '||a.table_name||' where '||a.column_name|| ' = '''|| b.trial_name||''';' "QUERY"
  from
  exp_csv_tB a,
  exp_csv_tr b;
