• How to use SQLite temporary tables?

  As read here: http://docs.blackberry.com/en/developers/deliverables/8682/BP_Optimizing_SQLite_database_performance...

  Use temporary tables. Do this only if you do not need data to be available following a reset of the BlackBerry device.

  Read here: http://www.sqlite.org/tempfiles.html

  Tables created using the syntax "CREATE THE TEMP TABLE" is visible only to the connection of database in which the "CREATE TEMP TABLE" statement is initially evaluated.

  The confusing part is that if I create an instance of database for temporary tables with a single statement of DatabaseFactory.open, I am only able to use this same instance of database throughout my entire application?

  So, using the same variable throughout the entire application?

  It also means that I can not close the database connection?

  Here is information on temporary tables of SQLite:

  http://www.SQLite.org/tempfiles.html#tempdb

  (1) you must call 'CREATE TABLE TEMP' every time when you open a database if you need this chart.

  (2) temporary table deleted as soon as you close the database. This means you need to keep the database connection open if you want to run previously inserted/updates of records into a temporary table.

  Thank you

• 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.

• Campus solution 9.0: engine Application parallel treatment of the Instances of the temporary Table

  People,

  
  Hello. I'm working on 9.0 Solution on a University Campus. I'm working on the module of Community Campus. I face a problem like below:

  
  Campus Community > personal information > add/update a person

  
  I can type in all the information for a person successfully and save it with success. But what research, it does not return anything to PS user
  This is because the security of access to demographic data is not granted to the user. So, I put security as below:

  
  Step 1:

  Set Up AWAR > Security > Secure Student Administration > permissions list > access to demographic data: I have select permission list HCPPALL and EOEI9200 for the PS user

  Step 2:

  Set Up SACRED > Security > Secure Student Administration > process > access to demographics: the process to initialize the authorization indicates to the user PS process program is the Application Engine. The process name is MSK_CFG. The process is not successful and returns an error as below:

  Table or view does not exist. Has no SQL statement: Truncate Table USER.PS_MSK_CFG_TAO4.

  
  The above error is that of the motor parallel processing Application on instances of the temporary table. There are 2 modes: online and batch. I run it in 2 modes as below:

  Online mode:

  Step 1: Navigator PeopleTools > Public Services > Administration > PeopleTools Options: I change 3 to 4 for the Instance of the Temp Table total and online.
  Step 2: Create a new control ID Temp1 and execute processes on Navigator SetUp > Security > Secure Student Administration > process > process of demographic data. The MSK_CFG process runs successfully, but the output file contains the message:

  ATTENTION: Application request engine is not active! Suspended treatment!

  
  So I run of steps 3, 4 and 5 in Batch mode as below:

  Step 3: Navigator PeopleTools > Application Engine > application Application Engine > engine Application request Page > add a new control ID Temp1.
  Step 4: Run the MSK_CFG with Temp1 process again and get the error:

  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO5.

  Step 5: I change 4 to 5 navigator PeopleTools > Public Services > Administration > page PeopleTools Option for the Instance of the Temp Table total and online.

  Re-run the MSK_CFG process and get the error:

  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO6.

  I have increase by 5-6 for the temporary Table instance and re-run the MSK_CFG process and get the same error with incremental number:
  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO7.

  I have increase by 6 to 7 and re-run the MSK_CFG process and get the same error:
  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO8.

  The maximum is 99, I continue to adding 1 to the Temp table instances and run the MSK_CFG process. But get the same error with differentials 1 as below:

  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO9.
  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO10.
  ... ...

  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO99
  Table or view does not exist: Truncate table USER.PS_MSK_CFG_TAO.

  My question is:

  Because the engine of the application is not active with a new control ID Temp1 in online mode, I add the new control ID Temp1 in the Application engine page request but get the error above.  How to solve the error above to begin the process of MSK_CFG?

  Thanks in advance.

  People,

  Hello. The problem is solved by myself.

  The thing is that we need to open the MSK_CFG_TAO of the temporary Table in the application designer and build. After construction, the table PS_MSK_CFG_TAO and PS_MSK_CFG_TAO1 come in the database.

  MSK_CFG process runs correctly now. Personal information of search returns data successfully. Thank you.

• Create a temporary table using EXECUTE IMMEDIATE

  Hello

  I need to create a report more complex which must have three different queries. I use a determined IF clause that the query that uses the report, according to the parameters.

  I want to write the output to a csv file, so I created a PROCEDURE.

  The first package of the procedure has the three SQL and the IF clause in order to determine the query that the report uses and stores the query code in a variable (v_sql), which is passed to the PROCEDURE that needs to write to the output of the report.

  I tried to create a table with data from the request in order to make a LOOP and exit, something like this:

  WRITE_FILE (errBUFF of the PROCEDURE	OUT VARCHAR2,
  	retCODE	OUT VARCHAR2,
  	v_sql	IN VARCHAR2)

  IS

  Contor

  NUMBER;

  BEGIN

  	EXECUTE IMMEDIATE v_sql;
  	SLIDE G
  	IS
  	Select * from XXROR_REG_MF_TBL;
  	--
  	-initialization
  	--
  	retCode: = 0;
  	errBUFF: = NULL;
  	Contor: = 0;

  	--
  	-cursor
  	--

  	FOR X IN G
  	LOOP
  	APPS. FND_FILE.
  	PUT_LINE)
  	APPS. FND_FILE. OUTPUT,
  	....)

  I should mention that v_sql is something like:

  CREATE GLOBAL TEMPORARY TABLE ACEs (SELECT * of the double);

  I can't really do that, so I was wondering if you have any suggestions

  Thank you

  Claudiu

  Hello

  I don't think you need a table at all. You can set the cursor based on the SQL passed as parameter

• CANCEL reading and overall-TWG temporary table

  Hello Expert!

  Based on an analysis made by my colleagues... He mentions on a compound of SQL to extract data only to leave a TWG and overturn readings! (Current_obj # ash captured as a event 0 and wait - db_file_sequential_read)

  The thought difficult to obtain a cancellation reason reading when extracting data from TWG!.

  On cancellation, cancellation would be needed!

  But as TWG specific Session, at any time in my session would read the latest copy for all operations. This reading must come from a buffer or disc (Temp).

  Why a reading of cancellation will be required?

  Can you please help me understand a scenario where cancel read for TWG is valid or unrealistic?

  Or conceptually missed something?

  Based on an analysis made by my colleagues... He mentions on a compound of SQL to extract data only to leave a TWG and overturn readings! (Current_obj # ash captured as a event 0 and wait - db_file_sequential_read)

  The thought difficult to obtain a cancellation reason reading when extracting data from TWG!.

  TWG activity generates CANCEL as a result of DML for any table. Which CANCEL then also causes RESTORE to be generated.

  On cancellation, cancellation would be needed!

  OK - but this isn't the only case of use.

  But as TWG specific Session, at any time in my session would read the latest copy for all operations. This reading must come from a buffer or disc (Temp).

  And that is where you get off the track. These statements are NOT correct.

  A session can open several sliders on these data TWG and these several cursors can represent a different "coherent reading" as far as data is concerned.

  Tom Kyte explains better in this AskTom blog.

  https://asktom.Oracle.com/pls/Apex/f?p=100:11:0:P11_QUESTION_ID:4135403700346803387

  and we said...

  Yes, temporary tables generate UNDO - and therefore to generate REDO to CANCEL it.

  Do it again for the cancellation must be created because Cancel is treated the same, the undo tablespace seems to be corrupted on an event of failure/media instance recovery if the cancellation has disappeared.

  The cancellation must be filed in support of the coherence of reading. For example, if you:

  (a) charge a TWG of temporary table with data

  (b) open cursor_1 SELECT * from TWG

  (c) update the data of TWG

  (d) open cursor_2 SELECT * from TWG

  (e) delete most of the data of TWG

  (f) open cursor_3 SELECT * from TWG

  Each of these sliders should see a different result set - we have not recovered from them, has just opened their. cursor_1 must push the blocks changed to point in time (b). This requires CANCELLATION. Thus, the cancellation must be generated - and undo is always protected by the roll forward.

  Changed blocks to the TWG, as for ANY table could be physically written to disk until the transaction is completed. It is not always room in the cache buffers for ALL data that has changed.

  And, as Tom above, each of the sliders really sees the data at a point different 'read-consistent. If some of these extractions of cursor will require reading the UNDO data for "compatible" data for this particular slider.

  The point in time' is established when a cursor is open - no data has yet been read yet.

  See the section 'Multiversion Concurrency Control' of the doc

  https://docs.Oracle.com/CD/B28359_01/server.111/b28318/consist.htm#i17881

  Multiversion Concurrency Control

  Database Oracle automatically provides the reading consistency to a query so that all the data that sees the request comes from a single point in time (at the level of instruction read consistency). Oracle database can also provide read consistency to all queries in a transaction (consistency of reading at the level of transactions).

  Oracle database uses information stored in its rollback segments to provide these consistent views. Rollback segments contain old data values that have been changed by validated or recently committed transactions. Figure 13-1 shows how the Oracle database provides consistent reading using rollback segments data at the level of instruction.

  That reference above 'consistent read to a query' also applies when cursors are opened.

• 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.

• Create temporary table in the procedure

  I have a procedure which can be called at any time by multiple users. So I cann't use table in there, because on each call, the table is truncated and inserted. How can I create a temporary table in the procedure?

  Temporary tables in Oracle are different from other RDBMS like SQL Server.

  In Oracle, you create a global temporary table ONCE as part of the design of your database.

  create a global temporary table MyTableName (... columns...) on commit preserve rows;

  You can then use this table in your code as you would any other table.

  The difference is that any data that you insert in this table are only available/visible so that the code runs in the session, and if delete you / truncate the table it only removes the data for this session.  In this way, several sessions we can table without interfering with each other.

  (Note: instead of "preserve" you can change this to "delete" If you want that deleted data automatically when a commit is issued in your session, otherwise the data will be automatically deleted at the end of the session)

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

• Inserting into a temporary table

  Hi all

  I use this code to insert into a temporary table

  INSERT INTO VISIT_TEST

  (NO, VISIT_ID)

  VALUES

  (1,: ALL_ADMITTED_PATIENT.) VISIT_ID);  -guess: ALL_ADMITTED_PATIENT. VISIT_ID is another number.

  COMMIT;

  It inserts nothing,

  but when I try to insert all the values of pl/sql with the same way

  INSERT INTO VISIT_TEST (NO., VISIT_ID) VALUES (2, 4);

  It inserts with success.

  the code for creating the table of tempo is

  CREATE A VISIT_TEST GLOBAL TEMPORARY TABLE (NO NUMBER, NUMBER VISIT_ID) COMMIT PRESERVE ROWS

  Why does not insert on it data?

  PS: the whole issue is that I run a report from a form, and the query of the report is based on the temporary table.

  what I want to know is, when I run the report from inside my form, is considered a new session, and this is why the report cannot see the data in the table of tempo or am I wrong?

  Thank you

  > when I run the report of my form, which constitutes a new session, and this is why the report cannot see the data in the table of tempo, or am I wrong?

  You're not bad. Forms and reports use separate database sessions. Reports can not see TWG data entered via Forms module.

• 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.

  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

  -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_outr varchar2 (50);

  p_xml XMLTYPE.

  Start

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

  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.

• Why create indexes use non-temporary tables?

  Looking into creating this index R-Tree, I noticed that all the staging tables are created as permanent instead of temporary tables.

  Why create a land index do this?

  Create the staging tables as temporary tables should reduce significant global creation time - what I'm missing here?

  Bryan

  Temporary tables are session-private. In other words, the different parallel slaves

  sessions may not see the same temporary tables.

• Clarification of temporary Table

  I have a small question, I think that must be answered easily, but I couldn't find anything it clarify for me online.

  I have a statement:

  CREATE GLOBAL TEMPORARY TABLE MATR_RPT
  ()PERCENTAGE varchar2()40),
  NUMBER of NUM_OF_CONTRACTS,
  NUMBER OF NUM_OF_CONTRACTS_C
  )
  on commit preserve rows

  BUT if I used "on commit preserve rows" who wouldn t be the same using a standard non-temporary table if it maintains the lines? Or I have forgotten here?

  Thank you!

  on validation keeps the lines:

  On the temporary table will remain once the transaction is complete. These recordings will live as long as the session that inserted is connected to them. After that this session left (dc), records have disappeared.

  on commit delete rows:

  On the temporary table will be gone when the transaction is closed without worrying if the session remains online or disconnect after.

  Concerning
