How to move data from one database to another one?

I 'd like to build up a new database, some of the data would come from an old database, then I have to make two connection objects to both databases, (two statement objects...) retrieving the data from the old one and inserting them to the new one.... sounds reasonable, huh? but it could not work this way... "........it would have caused the duplicated value , blah, blah..." even though I made two tables in two databases completely different, that errors are still there. seemed I cannot clone that table.
could you guys have any better ideas? and why couldn't I go this way?
the database: cloudscape3.01
two databases are all on my local PC (WinNT4.0)
thanks

If you are getting dupicate record errors, then look at your recordset objects and make sure they are both pointing at seperate databases, and check the one you are using to output and make sure it isn't just writing NULL, if it is then trace up the line: your input (read) recordset may be reading NULL too.

  • How to move data from a staging table to three entity tables #2

    Environment: SQL Server 2008 R2
    I have a few questions:
    How would I prevent duplicate records, when/ IF SSIS is executed many times?
    How would I know that all huge volume of data being loaded in the entity tables?
    In reference to "how to move data from a staging table to three entity tables ", since I am loading large volume of data, while using lookup transformation:
    which of the merge components is best suited.
    How to configure merge component correctly. (screen shot is preferred) 
    Please refer to the following link
    http://social.msdn.microsoft.com/Forums/en-US/5f2128c8-3ddd-4455-9076-05fa1902a62a/how-to-move-data-from-a-staging-table-to-three-entity-tables?forum=sqlintegrationservices

    You can use RowCount transformation in the path where you want to capture record details. Then inside rowcount transformation pass a integer variable to get count value inside
    the event handler can be configured as below
    Inside Execute SQL task add INSERT statement to add rowcount to your audit table
    Can you also show me how to Check against destination table using key columns inside a lookup task and insert only non
    matched records (No Match output)
    This is explained clearly in below link which Arthur posted
    http://www.sqlis.com/sqlis/post/Get-all-from-Table-A-that-isnt-in-Table-B.aspx
    For large data I would prefer doing this in T-SQL. So what you could do is dump data to staging table and then apply
    T-SQL MERGE between tables (or even a combination of INSERT/UPDATE statements)

  • HOW TO MOVE DATA FROM INT-TABLE TO DATABASE STRUCTURE?

    DEAR ALL!
    CAN ANY ONE GIVE ME SAMPLE CODE TO MOVE DATA FROM INT -TABLE TO DB-STRUCTURE PLEASE.
    I HAVE THE VALUES IN TABLE AND I NEED TO UPDATE STRUCTURE.
    REGARDS,
    VJ

    Hi,
       If you want to update a db STRUCTURE it is not possible because Structure doesnot hold any data.
    If you are trying to update a db table  then the update command should do the work.
    Eg : UPDATE VBPA3 FROM TABLE DA_XVBPA3U.
    Note :  The Internal table should be of same structure and should not have duplicate entries.

  • How to move data from one account to another?

    Sheesh, I think I've created a monster for myself.  I got a new macbook pro and migrated my data from Time Machine.  As I was doing everything I didn't realize that the set up for the computer was in a different account than the migrated data went to.  So I have my main account on the computer and another account with all my emails, itunes pics etc. 
    I think the other account is considered the main account on the computer so just to make sure I have all my privileges etc, I want to transfer all this data into the main account.  Does that make sense? 
    I started figuring all of this out as a problem when my second account (the one with all my old data) could not download podcasts.  I can do that with the main account. 
    Anyway, can anybody tell me a simple way to transfer all of this?  Should I just try to start all over?
    Thanks!

  • How to retrieve data from the Database after deleting rows from VO ?

    Hello,
    I am using Jdeveloper 11.1.2.1.0
    I have a master and a child .
    So according my use case when a value in the master vo changes the corresponding child has to be deleted.
    but when i change back to any other value i want to undo the delete operation and get back the values in the child.
    Is there any way to do it?
    Regards,
    Nigel.

    Hi all,
    I want to do a validation based on a SelectOneChoice List Value.
    Based on which value in the select one choice is being selected, thedata from the VO should be DELETED or NOT-DELETED.
    To do this I wrote a Managed Bean and the delete part is working fine if a particular value of the SelectOneChoice is selected.
    Since the rows are deleted from the VO, after I change the SelectOneChoice value to the previous one I cannot retrieve the rows.
    I thought of two ways:
    1. As the Deleting option in the SelectOneChoice is selected the rows should be deleted from the VO and when reverted back to not-Deleting option the Rollback of Transaction method written in the Managed Bean should take place.
    2. As the Deleting option is selected the data should be deleted from the VO and when reverted back to non-Deleting option, a query should be made from the Database.
    The first plan was dropped because it is not VO-specific. If there are more than 1 VO in the page then whatever changes are made in the page will be reverted back as soon ad Rollback of transaction is done.
    So the now i am left to go with the second plan.
    Is there any way to implement the second plan?
    If so...Will it compromise the performance of the application?
    Or else, Is there any other way to implement my Use-Case ???

    Nigel.

  • Move APEX Installation from one database to another one

    My task is to move an APEX installation to a new one.
    Exact: The customer wants to downgrade from Enterprise Edition to Standard Edition.
    Database version is 9.2.0.8 (both), APEX version is 2.2.1
    What I've done:
    - Full database export (from EE)
    - Delete EE-software, reboot server
    - Install. SE-software, reboot server, create db
    - Full database import
    around 40 db objects are invalid after recompile:-(
    2. try:
    - create db (SE)
    - Install. of APEX 2.2.1
    - Import of the schemas flows_020200, flows_files and the APEX user-schemas
    - recompile
    all db objects are valid, but the APEX applications belongs to a workspace "unknown" so no workspace have access to its applications:-(
    Has anybody an idea or a recipe for me?
    Many thanks

    Hi, Scott –
    Thanks for your post on this thread last Friday evening, May 2. I posted my message on Wednesday April 30, and after receiving no response after two days, we decided to go ahead with my planned migration on Friday afternoon. We completed it shortly after 5:00 PM (just six hours before you posted your response). Everything seemed to go well, but based on your expert opinion, we've decided to scrap the TARGETDB installation and redo the migration according to your recommendations.
    It seems that exporting each Apex application individually from the SOURCEDB and importing it individually to the TARGETDB would be a laborious and lengthy process, but if Oracle provides no faster and more convenient alternative, then I guess this is something we’ll have to do.
    However, this has sparked more questions….
    Like I said in my previous post, we’re relatively new to Apex. When I mentioned exporting/importing Apex workspaces, I was imprecise in my terminology. I know you can export Apex applications from the SOURCEDB Apex installation and import them into the TARGETDB Apex installation using the Web based Apex Admin tool. But can/should you do the same with workspaces? Or do you recreate corresponding empty Apex workspaces on the TARGETDB and then import the appropriate Apex applications into them?
    What would you suggest to be the best way to do this?
    Thanks again for your help!

  • How to load data from different database

    Hi,
    My problem is how to load Foxpro 2.6/clipper data into oracle 8 with all its structure and data with SQL loader or other utility if any.
    And also how can i integrate existing forpro system into Oracle. i.e client will work on Foxpro application and we will only take its output(data files) on daily basis and convert it into Oracle 8.
    Please find any solution.
    Regards
    null

    You can also try to make up an ODBC connection to Foxpro and convert the data from foxpro to oracle using the COPY command (see docs on PL/SQL & OCA). I remember that foxpro/clipper are running on MS-DOS, so I don't know if you can establish an ODBC connection to oracle which can be used from the foxpro/clipper application to use it as a frontend for an oracle database.

  • Move Data from Converted Database Objects Successfully Finish ?

    I am using SQL Developer 3.2.20.09 try to migrate KSMMS database from SQL Server 2008 to Oracle 11g R2. After the migration process is done, the Captured Database Objects model, and Converted Database Objects model have been created in the Migration Projects Navigator panel on the left side, and the corresponding sql scripts has been generated in the project output directory. I run the sql scripts, it created all the tables, views, index and stored procedures in the oracle database, everything seems working perfectly. However when I try to Move Data (by right clicking Converted Database Objects) and try to move all the data from SQL Server to Oracle database, the Data moving process run less then 1 minute, and show me the result as Data Move successfully. I have about 1 GB data in the SQL Server database, it seems nothing has been moved into Oracle DB. Here are the detail structures of MS SQL Server Database which I am trying to migrate to Oracle:
    The SQL Server Database name is KSMMS, under that database there are 9 users (azteca, cwweb, dbo, guest, plladmin, pw, pwadmin, tbills, wsdadmin). All my application objects (tables, views, indexes, procedures) are under azteca user, during the migration process, Converted Database Objects creates user azteca_KSMMS and dob_KSMMS, all my application objects have been created under azteca_KSMMS user schema. The generated .sql scripts actually can create all the objects under azteca_KSMMS schema, however when I try to Move Data, nothing has been moved into Oracle database. I opened an SR#3-6708733861 last Friday, it seems Oracle Support can't find what cause the problem during the Data Move process. Any help regarding my questions will be highly appreciated. Thanks.
    Kevin

    I changed Data Move Mode to Online and run the Data Move again. Same Results: Migration action have completed successfully. However no records have been moved into Oracle tables.
    I am running SQL Developer under Windows 8 Operation system. There is no Oracle client software available for Windows 8, does that cause any problems?
