• How to insert into a GLOBAL TEMPORARY TABLE and get the data from it?

  The requrement is
  Split the string ENTRY point on the base and store it in a Collection. And the values of the collection will be stored in a global temporary table. Then, I'm updating some other table based on the data from the temporary table.
  
  There is in fact no error message. But there is no data in the temporary table and also no change in the update statement
  
  First of all, I'm creatiing a global temporary table only once outside the procedure.

  Update first_tbl set PIN is "XXX" where first_col in (select data_element from TWG);.
  commit;
  
  END test_proc;

  Remove the two execute immediate line. They are wrong.

  And then use the table in your code that you created at the beginning. The name is GLT.
  And delete the first commit. This validation would empty the temporary table of GLT.

  You get an error? Or it does not work as expected?

  Also, show how you call the procedure.

• How can I write the trigger for the global temporary Table

  Hi Grus,
  How can I write the trigger for the global temporary Table.
  
  I created the TWG with trigger using the script below.
  
  
  CREATE A GLOBAL_TEMP GLOBAL TEMPORARY TABLE
  (
  EMP_C_NAME VARCHAR2 (20 BYTE)
  )
  ON COMMIT PRESERVE ROWS;
  
  
  CREATE OR REPLACE TRIGGER TRI_GLOBAL_TEMP
  BEFORE DELETE, UPDATE OR INSERT
  ON GLOBAL_TEMP
  REFERRING AGAIN AS NINE OLD AND OLD
  FOR EACH LINE
  BEGIN
  INSERT INTO VALUES EMPNAME (: OLD.) EMP_C_NAME);
  END;
  /
  
  
  trigger was created successfully, but her would not insert EMPNAME Table...
  
  Please guide if mistaken or not? If not wanting to give a correct syntax with example
  
  
  Thanks in advance,
  Arun M M

  BEGIN
  INSERT INTO EMPNAME VALUES (:OLD.EMP_C_NAME);
  END;
  

  you are referencing old value in insert stmt.
  
  BEGIN
  INSERT INTO EMPNAME VALUES (:new.EMP_C_NAME);

  then run your app, it works very well...

  CREATE GLOBAL TEMPORARY TABLE GLOBAL_TEMP

  CREATE OR REPLACE TRIGGER TRI_GLOBAL_TEMP

  INSERT INTO EMPNAME VALUES (:new.EMP_C_NAME);
  dbms_output.put_line(:OLD.EMP_C_NAME);

  create table EMPNAME as select * from GLOBAL_TEMP where 1=2
  
  insert into GLOBAL_TEMP values('fgfdgd');

• Global temporary Table problem in ADF

  Hello
  
  I have an application where I need to use a TWG (on the ranks of commit preserve) DB and try to insert data to TWG of screw ADF.
  But the table does not store data even after the Commit command. [Even I tried with permament DB table, and it worked.]
  
  Could someone help me find the problem with inserting data TWG.
  
  
  Kind regards
  Manju

  It is not a good idea to use a global temporary Table in an ADF application. The problem is that all web applications are really stateless. ADF maintains the State of a session data backup or reload it when necessary. Regarding the database, ADF can disconnect a session from the database at any time and connect to another session. This means that you do not necessarily have a continuous database session, then the lines you wrote to a TWG may well gone with the following query. There are ways to tell ADF not to do, but they have a considerable performance drop.

  Therefore, rethinking how you will save temporary information for the duration of a user session. You can do it in an object view ADF BC (VO) - interviewed by VO data carried session - if ADF needs to share a user session to load the data of another user (this is called "passivation") it will save these data. Then when ADF 'active' session, he'll find the saved data and reload it. Or you can use a permanent table with your name or session id - a little more complicated, but possible.

  If you want to tell us a little bit your use case - you need your application to do so, we may have other alternatives.

• 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?
  
  CREATE A GLOBAL TEMPORARY TABLE 'EMP_SESSION '.
  (SELECT "EMPNO" NUMBER NOT NULL,)
  'ENAME' VARCHAR2 (10),
  VARCHAR2 (9) "JOB."
  NUMBER OF "MGR."
  "HIREDATE" DATE,
  NUMBER OF "SAL."
  NUMBER OF THE "COMM"
  NUMBER OF "DEPTNO".
  ) ON COMMIT PRESERVE ROWS

  insert into emp_session (EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO)
  Select * from EMP

  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

• What is the best (global temporary Table or tables of Type Object)

  Dear all,
  
  I'll try to refine some code and find that we have a large loop that goes to loop over 100000 times and for each record, it in turn for validation of controls in individual tables.
  
  I intend to implement all of the functionality of controls using join conditions. I.e. to empty all the data into a global temporary table or tables oracle object type and apply the conditions of verification using join operations, so that I can avoid the unnecessary check for each record.
  
  If I want to implement this, I want to know what is best. A global temporary table or the Oracle Tables nested.
  
  Appreciate your response.
  
  Thank you
  MK.

  If you mean a global temporary table vs a variable from PL/SQL grouping, then 100 + lines is a lot to store in session memory a GTT would be so a more scalable solution. It will give you more options to manipulate the data using SQL.

  Note that a 'table of type object', or 'table object type' can mean a table of database (no PL/SQL) for example "CREATE TABLE MyTable mytype". However, I don't think you mean that.

• global temporary table in oracle

  HI all,
  I want to know more about TWG in oracle, why we use it, cant why we use table bunch (we can truncate and we can use) as TWG, please help me

  The data in a temporary table are private to the session that created and can be specific to the session or operations. If the data are deleted at the end of the transaction, the table must be defined as follows:

  CREATE TEMPORARY table GLOBAL My_Temp_Table (NUMBER of Column1, Column2 NUMBER) ON COMMIT DELETE ROWS.

  If on the other hand that data should be kept until the session ends, it should be defined as follows:

  CREATE TEMPORARY TABLE global my_temp_table (NUMBER of Column1, Column2) ON COMMIT PRESERVE ROWS;

  Various characteristics
  1. If the TRUNCATE statement is issued against a temporary table, only the specific session data trucated. There is no impact on the data of the other sessions.
  2. the data in temporary tables is automatically delete at the end of the session of the database, even if it ends abnormally.
  3 indexes can be created on temporary tables. Content in the index and the scope of the index are the same as the database session.
  4. the views can be created against temporary tables and combinations of temporary and permanent tables.
  5 Tempoarary tables can have triggers associated with them.
  6. export and import utilities can be used to transfer table definitions, but without data lines are treated.
  7. There are a number of tables linked to temporary restrictions, but here are the specific version.

• Are global temporary tables, a standard feature of Oracle?

  I apologize for introducing me to this community with what must seem like a very stupid question...

  I am a software developer, working on a product that uses Oracle as its database, specifically Oracle 11 g Enterprise Edition. Recently, I solved a problem of performance by converting an ordinary table into a global temporary table. Before my boss allows me to put this change in the product, it wants to be sure that global temporary tables are a standard part of Oracle, not something that the customer must install separately or pay extra for. (This is the first time that we never used them in our product, so I think that most of the team are not familiar with them).

  I know that Oracle has had global temporary tables since the last millennium, so if ever, they have been a feature of the premium, they are unlikely to be now, but the boss wants me to get independent confirmation of this.

  Thank you.

  Steve Pemberton

  Here you can see "feature availability by Edition":

  http://docs.Oracle.com/CD/E11882_01/license.112/e47877/editions.htm#DBLIC116

  TWG tables is not even mentioned, which means that they do not belong to the functional components are paid separately.

  One caveat - if you have an application that uses connection pooling, it is recommended to use ON COMMIT DELETE ROWS, not ON COMMIT PRESERVE ROWS

  (or always use explicitly "DELETE gtt_table" at the beginning), because otherwise a user of the application can display the data TWG who has previously made a second user of the application.

• find global temporary tables

  Hi all

  How to find global temporary tables in all_tables, is this possible?

  What:

  
  select * from all_tables where temporary = 'Y';
  

• What to fill in 'field of the temporary table' for global temporary tables?

  Hello

  I use the Data Modeler 4.0.1.836 and everything that I put in the box 'the scope of the table temp' for a global temporary table doesn't seem to affect the DDL script about the ON COMMIT PRESERVE/DELETE the LINES option. The script poster ON COMMIT PRESERVE ROWS always anything.

  Yet, some of my temporary tables must be created as ON COMMIT DELETE ROWS.

  Using the Data Modeler wrote about it:

  Scope of the temporary Table:

  For a class as a temporary table, you can specify a scope, such as the Dimension or the Session.

  Not sure what 'Dimension' has to do with the scope here, but it makes no difference.

  I tried to put 'Session', 'Dimension', 'Operation', but no luck. So what is the text for the script generate ON COMMIT DELETE ROWS?

  Thank you

  Hello

  The temporary Scope of Table property (on page Types of Classification of the table properties dialog box) is purely documentary.

  To set ON COMMIT DELETE ROWS you must expand the browser for the relational model and find the node for the relevant Oracle physical model.  If you develop it you will find an entry there for your Table. Double-click on that to get the physical model properties dialog box for your table, and you will find a "Temporary" facility that has options (Preserve Rows), YES (Delete Rows) YES or no.

• Global temporary tables

  Hi, db 10g,

  I created a global temporary table with this statement:

  create a table temporary global items (item_id);

  and tried to insert inside of Toad, and I got the message

  1 row inserted,

  but when I asked it, I got

  no selected line?

  I tried the script several times, and the result is the same?

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

• 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

  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

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

  This query actually belongs to SQL and PL/SQL Forum. Please take care and post in the correct forum.

  In any case...
  CREATE TABLE TEMPORARY global is a DDL command. Once created TWGS will exist until he FELL. Try to create a TWG with the same name will fail. just like any table, view, etc. See http://docs.oracle.com/cd/B28359_01/server.111/b28310/tables003.htm#i1006400

  a: you can create a TWG once and use/re-use it anywhere in your code.
  (b) as it is a DDL you can not use in the DECLARE section. You can use BEGIN and EXCEPTION.

  See you soon,.
