• What is the syntax to create segments?

  Hello

  segment can be created manually as table space? If Yes, what is the syntax to create the segment?

  Concerning

  The create table statement has a storage clause that is part of the clause of physical attributes.

  These clauses to define options for the creation of segment/measure. If you do not specify the storage clause, then the tablespace-level settings are used.

  Physical properties: https://docs.oracle.com/database/121/SQLRF/statements_7002.htm#i2126711

  )

  However, the create table statement lets you not create segments or extensions directly. New extensions are to be created initially (when the table is created) or later, when more space is needed for the table, usually after several insertions that filled the original measure.

  Also remember that SQL is a language of generation 4. But there is no need to go into details such as the management of use or storage. All that and managed by the RDBMS.

• create a global temporary table

  Hey there,
  
  I want to create a global temporary table, recovering data from another table inside a procedure.
  can you please help in this regard?
  
  Thank you.

  You said:

  1. create the TWG
  2. insert data from hand of TWG
  3 insert data of TWG to some other table_new according to table
  4 remove the main classification data

  Why do you need all TWG?

  Simply insert the data of table to the main table table_new
  delete the same data from the main table.

• SELECT the data inserted into a global temporary Table in a stored proc

  A stored procedure is run from Oracle SQL Developer to insert data into a global temporary table. A SQL (in Oracle SQL Developer) worksheet is open to run a SELECT query to retrieve the data from the temporary table overall which was populated in the stored procedure. No row is returned. I guess it's because the stored procedure and the SELECT statement executed in different sessions.
  
  Is it possible to run the stored procedure in Oracle SQL Developer and then execute a select statement on the temporary table overall which was filled in the stored procedure by using the same connection so that the data can be extracted?
  
  I use version 1.5.1 build HAND-5440 of Oracle SQL Developer.

  In a worksheet, do something like

  Start
  insert_proc;
  end;

  Select * from my_temp_table;

  Place the cursor on each statement in turn and Press f9 (where it all began... the end is a single statement.

• What is the syntax for displaying tree based on a correlated subquery

  I need to show an effective dated tree. The reference date for the tree will be selected by the user. To do this I use a subquery to correlated against the underlying table with the entry into force provided as a bind variable. The following statement returns I want:
  
  SELECT a.tree_id, a.tree_pid, a.tree_leaf_name
  OF cit_fin_organization one
  WHERE a.effective_date =
  * (SELECT MAX (a1.effective_date) *)
  Cit_fin_organization A1
  WHERE a1.tree_id = a.tree_id
  AND a1.effective_date < =: f164_point_of_view_date)
  
  
  Adding where clause at the APEX generated SQL for the tree:
  
  Select "TREE_ID" id,
  * "TREE_PID" pid, * "
  * 'TREE_LEAF_NAME name, *.
  *'f ? p = & APP_ID.:51: & SESSION. : NO::P51_TREE_ID :'|| "' Link TREE_ID" *
  null a1,
  null A2
  of ' #OWNER # '. " CIT_FIN_ORGANIZATION ".
  
  is simple, but I did not come with the syntax that will successfully pass the SQL with aliases to the parser. Without references alias the request with its correlated subquery does not return, of course, the correct results.
  
  Can someone show me the correct syntax or suggest another way to accomplish what I want to do?

  Hello

  I don't have the structure of the table that you have, but the following works on the EMP table:

  select a.empno id,
         a.mgr pid,
         a.ename || ' ' || TO_CHAR(HIREDATE,'DD/MM/YYYY') name,
         null link,
         null a1,
         null a2
  from EMP a
  where a.HIREDATE <= (SELECT MAX(b.HIREDATE)
  FROM EMP b WHERE a.empno = b.empno and b.HIREDATE <= TO_DATE(:P19_HIREDATE,'DD/MM/YYYY'))
  

  P19_HIREDATE is just a list of selection with all the HIREDATEs in the format DD/MM/YYYY. Of course, this isn't a thing of real but life shows you can use aliases and the elements of the page.

• What is the syntax for onMouseOver?

  I have an instance of the object called thumbnail1 with the following code...
  
  This ["thumbnail1"] .onPress = Function () {/ / code here works perfectly ;}}
  This ["thumbnail1"] .onMouseOver = this ["thumbnail1"] .displayHoverState ();
  
  When the user hovers over my object, I want my object to call the displayHoverState() function. Why it doesn't work?
  
  I think that the 'onMouseOver' syntax is incorrect. Since it is not highlighting the appropriate in the Panel code color.
  

  onRollOver is the right method. and displayHoverState() must be a function defined on the chronology of this.thumbnail1.

• What is the reason for creating the directory database in oracle instead of oracle could use;

  Hi all

  I want to know why oracle gave the concept of directory as a database object while a file on the operating system can be accessed directly by this last full qualified name. as we use the directory object in outer table and expdp etc.

  In addition to the above-mentioned security issues, there is the question of the independence of the OS.  By having the ability to refer to an alias that is not specific to the operating system, the application code doesn't have to worry about the physical (and so, os-dependent) mapping of a file.  Makes the code portable, which is one of the great features of Oracle vs everybody.

• What is the syntax to name a webapp/category classification using named parameters when the category is a subcategory?

  {module_webapps id = "" # "filter = 'class' itemid = 'Category name' model = 'collection1' collection =" ' "}

  Works very well...

  {module_webapps id = "" # "filter = 'class' itemid ="Name of the Sub category"collection model = 'collection1' =" ' "}

  
  

  Can't seem to get the subcategory to work, this will only work on the top level categories?

  
  

  That something is overlooked or I just need to know the right syntax?
  

  {module_webapps id = "webappnameorid" filter = 'class' itemid =' 'name of the Parent category /Sub category name "collection = 'collection1'" model = ""}

• Edit and a global temporary table

  Hi all
  
  Can someone tell me why when I create a TWG and insert the data as the followijng, I get insert 14 ranks msg. But when I do a select statement of the sqlwork shop, sometimes I get the data sometimes that I don't have. my understanding is that these data are supposed to stay during my session logon then got cleaned up when I left the session.
  I develop a screen in the apex and will use this temporary table for the user to perform editing work. Once Island edition done then I save the data in a static table. Is this possible? So far my every attempt to update that the temporary table always results in 0 rows updated in the temporary table and reversed to 0 lines. Can you help me?

  APEX does NOT support the use of TWG... Use rather a collection to manipulate your temporary data... : http://www.dba-oracle.com/t_easy_html_db_collection.htm

• Global temporary table Vs Table permanently to manipulate the transaction data

  Hi all
  
  Version of database - 10.2.0.4
  
  We need handle transactions, data in a table and put in an intermediate table (ie): to replicate the data in the tables of a schema of staging of the tables in the schema. Get info on transactions and handling.
  Can you please indicate which one of the below is the best option.
  
  Option 1:
  Create a global temporary table, each running process.
  
  Option 2:
  Create a table permanently and delete lines at the beginning of the process.
  
  Job expects every 5 minutes
  
  Thank you and best regards,
  Rakesh

  If data are transient and must be written to the disk (I'm not sure I follow your explanation for why written data on the disk are necessary - you have to touch table large transaction each time to fill the intermediate table) using a global temporary table. At least, you'll reduce the cost of writing the data to disk by generating less recovery.

  But ideally, you would not write the data on the drive at all and would be able to do it in SQL.

• Global temporary table in PL/SQL with XML

  Hello

  I have the impression that it is something strange or maybe I'm missing something basic.

  Step 1: Create a global Temp table that should not be specific transaction.

  create a global temporary table Temp01

  (

  NUMBER OF TICKET_ID

  , Varchar2 (10) of the REGION

  NUMBER OF THE YEAR

  , CO_ID VARCHAR2 (10)

  ) ON COMMIT DELETE ROWS.

  Step 2:

  My XML that goes as a parameter to a new function.

  < TICKET >

  < TICKET_ID > 38498051 < / TICKET_ID >

  the USA < REGION > < / REGION >

  < YEAR > 2014 < / YEAR >

  XYZ123 < CO_ID > < / CO_ID >

  < / TICKET >

  Step 3: Create a Stand Alone function:

  -drop function aagarwal.wr_creation;

  create or replace FUNCTION XML_FUNC

  (

  ret_msg out varchar2,.

  p_xmlval IN varchar2

  )

  RETURN varchar2

  is

  l_xmlval varchar2 (4000): = p_xmlval;

  V_CO_ID VARCHAR2 (10);

  V_CODE VARCHAR2 (10);

  BEGIN

  BEGIN

  INSERT INTO Temp01

  (

  TICKET_ID,

  REGION,

  BLEACHED,

  CO_ID

  )

  SELECT

  EXTRACTVALUE (XmlType (p_xmlval), "/ TICKET/TICKET_ID ') ID,.

  EXTRACTVALUE (XmlType (p_xmlval), "/ TICKET/REGION") REGION.

  EXTRACTVALUE (XmlType (p_xmlval), "/ TICKET per YEAR"),.

  EXTRACTVALUE (XmlType (p_xmlval), "/ TICKET/CO_ID ') CO_ID

  FROM DUAL;

  ret_msg: = 'SUCCESS';

  -SELECT CO_ID IN V_CO_ID of aagarwal. TEMP_STAGE_WR;

  -return ret_msg;

  EXCEPTION

  WHILE OTHERS THEN

  ret_msg: = sqlerrm;

  Return ret_msg;

  END;

  BEGIN

  SELECT CO_ID INTO V_CO_ID FROM Temp01;

  / * MERGE IN the site is

  With the HELP of aagarwal. TEMP01 T

  WE (T.co_id = se.code AND se.type_nm = ' TYPE' and se.src_nm = T.region)

  WHEN NOT MATCHED THEN

  INSERT (ID, SRCNM, CODE, TYPENM)

  VALUES (SHARED_SEQ. NEXTVAL, T.region, T.co_id, 'TYPE');

  -commit; */

  return ret_msg | "ACE" | v_co_id;

  END;

  END;

  /

  Fact - created function.

  NOTE: MERGE statement is blocked and if the function was created in sweetness.

  Step 4: Call the function

  declare

  l_out varchar2 (50);

  l_outr varchar2 (50);

  p_xml XMLTYPE.

  Start

  l_outr: = XML_FUNC (l_out, ' < TICKET >)

  < TICKET_ID > 38498051 < / TICKET_ID >

  the USA < REGION > < / REGION >

  < YEAR > 2014 < / YEAR >

  XYZ123 < CO_ID > < / CO_ID >

  (< / TICKET > ');

  dbms_output.put_line (l_outr);

  end;

  /

  
  

  Step 5: Check the value being inserted into the temporary Table:

  
  Select * from temp01;

  
  

  So far so good.

  THE PROBLEM:

  Now I want to tweek the XML_FUNC function above by uncommenting MERGE statement, which brings me to an error that is not differentiable:

  I.e. PL/SQL: ORA-00942: table or view does not exist in line on MERGE pointing to Temp01 statement.

  NOTE: I tested this Merge statement explicitly (as long as the execution of Stand Alone and also by calling via anonymous block PLSQL) and its absolutely perfect work. And SITE table exist.

  PS: I would be grateful, if there is a better way to write this code? I'm not a regular PLSQL developer and so badly can write the code of practice.

  Kind regards

  AAG.

  Using 11.2.0.3:

  Owner of all these three objects is DBA.

  Are you sure?

  After the release of:

  Select object_name, object_type

  of object

  where object_name in ('TEMP01', 'SITE', 'XML_FUNC');

  You must grant the explicit right to select on the table for the owner of the function if the owners are different.

  This works as expected for me (user DEV has all 3 items):

  No, the default is ON COMMIT DELETE ROWS.  I don't know why; ON COMMIT PRESERVE ROWS seems to be much more widely used.
