Ordinary table from the temporary table vs

Hello
What is the difference between a temporary table and a regular ODI table.

I created a temporary table mapping. Works very well. Now, I added the column in the mapping. To make it work, I have to drop the temporary table that created starting from my previous run or add the column in the temporary table. So I was wondering what is the difference between temp and a regular table in terms of maintenance.

How can I make adding new dynamic columns.

-app

Just to add to what others have said.

(Temporary interface or yellow Interface) to create (Temp Table or Table Stagging)
-------------------------------------------------------- ----------------------------------------------------------------

This method is used to create a temporary Table or Stagging table so that you can export your data before the load in the main target.
Also its always good practice to create them in the scheme of work (where $ tables are created), except if you required in your database schema.
This interface are marked by yellow color
Also these Interface can be dragged directly into all other Interfaces.

The main reason why they are not removed or delete which is then we cannot call in the following Interface to load the target.

tables of $
------------

Here's the ODI tables it creates before loading the data into the target as ODI works with ELT concept where his charges into a temporary table (C$, I$, $ J etc.). ODI after loading data in these tables $ can do the necessary transformation and finally load into the target table.
Once the loaded data to compeltely there ' won't be any use of these tables so they let down, even if you have not deleted by havingthe option
Delete temporary objects - not in LKM and IKM. Generally used for debugging, but once you have finished debugging, make sure that you return Yes, ODI else will not remove these tables of $.

How can I make adding new dynamic columns.

Although I see no reason to drop the temporary table or tables intermediaries. Its good to drop in the database and run your IKM, but again please find a way to do it using revenge for your reference.

Step 1 - create a copy of your IKM

Step 2 - Add another command called Drop Target Table and use the following code

 Drop table  <%=snpRef.getTable("L", "TARG_NAME", "A")%> 

Move it before you create the target Table.

Step 3. Added an option - Drop Table target, so that you can specify whether to drop or not. Go on command and option and instead of always run, check the Drop target only Table option.

That way if you do not want to delete the target table, it used to other specify Yes.

I hope this helps.

  • How to retrieve messages from the temporary file of windows in the form of text messages

    Hello

    We have used Thunderbird on Windows 7 for almost a year. And we have been very happy with it and had no problems.

    Today, somehow it has taken during the last six weeks of the messages in our Inbox and moved them in the mailbox of Archives in a folder called '2015 '. I don't know how or why it does this.

    More important still, when I opened this file and attempted to transfer the messages to my Inbox, messages simply disappeared. I finally found them under the Windows Temp file.

    I tried to recover these messages in our Inbox, but all attempts have failed. All messages now have a text file extension. My guess is that the file type is not correct now.

    How can I get these messages restored in my Inbox?

    Thank you

    GMS

    After looking for the message objects based on my outgoing messages during the period, I finally found the missing incoming messages. They were in the Inbox of my Eudora import. I must have put there by mistake instead of the Inbox for my main account. Me dummy.

    While I am relieved to have found them, I still don't know how the Archive was created in the first place. But I don't want to give credit to some creative stepping of a cat. More probably, they hit the right keys to make it happen. I suppose a programmer of Thunderbird could know how it happened.

    Thanks to all who tried to help.

  • Away from the temporary folder content

    What seems to be two different Temp folders; We type in folder in the search bar of the menu then clicking on the icon, then another using a shortcut created for C:\user\me\AppData\Local\Temp

    The content is drastically different depending on how I get there.  The paths are the same.

    What is the meaning of this?

    Thank you.

    Open a prompt, type command:

    echo folder

    Press ENTER, and then copy the results here.

    Right click on the shortcut created and see the properties and copy the path to paste the results here.

    This will verify that the paths are the same.

  • Is a database table that is required for the temporary interfaces with the data flat file source?

    People, this is the situation I ODI 11.1.1.7

    1. I have an interface temporary (yellow), called MJ_TEMP_INT, which uses data from TWO sets of data from the source in a temporary target (TEMP_TARG). Wrestling is a shot of a data set from a table while the other set of data extracted from a flat file.  A union is made on data sets.
    2. I then create another interface, called MJ_INT, which uses the MJ_TEMP_INT as the source and the target is a real database. table called "REAL_TARGET".

    Two questions:

    1. When I run my second interface (MJ_INT), I get a message "ORA-00942: table or view does not exist" because it is looking for a real TEMP_TARG db table. Why I have to have one? because I am pulling a flat file?
    2. On my second interface (MJ_INT) when I look at the interface of my source MJ_TEMP_INT (yellow) property sheet, the box 'Use the temporary interface as a Derived table' is DISABLED.  Why? Is also because my temporary interface is pulling from a flat file?

    I am attaching a file that shows a screenshot of my studio ODI.

    Furthermore, IF my temporary source interface has only a single set of data by pulling from a database. Table to table in a temporary target, called MJ_TEMP2_TARG, and then when I use this temporary interface as a source to the other another real db. target table (REAL2_TARGET), THEN everything works.  ODI requires me to have a real database. Table MJ_TEMP2_TARG and the checkbox for "interface temporary use as a Derived table" is NOT DISABLED and my REAL2_TARGET table gets filled.

    Thank you in advance.

    Mr. Jamal.

    You quite rightly assume the reasons that you have questions is because you try to attach a file. A file I always have to be materialized in the transit zone, as a temporary table and then have the data loaded in it.

  • The temporary and tables using SQL tuning tools

    The application that I support uses temporary tables for the majority of queries... Looking at the SQL tuning advisor and more of other oracle tuning tools, they seem well managing temporary tables.

    It's what Happens (from what I can tell).

    (1) oracle identifies a SQL statement (or the ADMINISTRATOR only), to be tuned.
    (2) the original execution statistics are saved for comparison
    (3) oracle tries to find a new plan (but at this point, the temporary table is empty).
    (4) it tries to execute the new plan (once again the temporary table is empty).
    (5) it comparies the execution time of the new plan against the original plan

    The comparison, of course, is not a reasonable comparison.

    Does anyone have experience with this problem? My first thought is for 'premium' of the temporary table, then run the Advisor of tuning in the same session (hoping that it will use the values in the temporary table).

    Other than that, rereading of the database seems to be the best way to adjust sql plan changes using baselines.

  • Table temporary global vs create and drop an ordinary table in pl/sql proc

    Hello!

    I currently have these statements in a pl/sql procedure:

    As you can see I am falling and re-creating a table. The table is used as an intermediate storage for a larger SQL following further in my procedure (not shown in this post).

    My question is:
    Y at - it an advantage or a drawback in using global temporary tables (gtt) instead of the create and drop an ordinary table? The table contains about 7000 records and is not needed more once the procedure is complete. The procedure runs once per day, every day of the year

    We are running Oracle 9iR2.

    And finally, please do not look to find errors in SQL statements above. They are slightly darkened and still developing. The basic question is if TWG's benefit to the common way to do it.


    Thank you in advance for your help!

    user7066552, the use of temporary tables may be a necessity in SQL Server and mySQL, but with Oracle and its authors do not block readers reading model consistency using temporary tables as part of the treatment is generally unnecessary.

    A valid use for a table of work could be where you create an operating table that is used to generate reports that are run on demand and several different users need access to the same data. However, you create the work only one table and truncate it prior to restocking rather than drop and it dynamically create. When only the current process will use the data a TWG is the way to go if you must have a table that is "temporary".

  • 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.

  • 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.

  • Generic procedure to load the data from the source to the table target

    Hi all

    I want to create a generic procedure to load data of X number of the source table to X number of the target table.

    such as:

    Source1-> Target1

    Source2-> Target2

    -> Target3 Source3

    Each target table has the same structure as the source table.

    The indexes are same as well. Constraint are not predefined in the source or target tables.there is no involved in loading the data from the business logic.

    It would simply add.

    This procedure will be scheduled during off hours and probably only once in a month.

    I created a procedure that does this, and not like:

    (1) make a contribution to the procedure as Source and target table.

    (2) find the index in the target table.

    (3) get the metadata of the target table indexes and pick up.

    (4) delete the index above.

    (5) load the data from the source to the target (Append).

    (6) Re-create the indexes on the target table by using the collection of meta data.

    (7) delete the records in the source table.
