Finding difference between 2 databases

Hi Folks,
I have the following problem:
I have 2 databases, database old, database new. Database new has modified/removed/added/inserted rows. Also columns in the db can also be modified. So what I have to do is to find the set of SQL statements which if I execute on database old, will make database old same as database new. Modification is only in data, not triggers etc.,
I have explained my manager that this is not very easy to implement. Even finding difference between 2 DB is not trivial. Do you guys have any suggestion for me? whether in terms of implementing it or even convincing my boss is fine :)
Are there any open source tools to do this? I am in big trouble now :(
Thanks,

Unless there is some other goal that you have not mentioned this is fairly easy.
Just delete all the tables from the old database using SQL delete tables and then create new tables and populate them with data from the new database.
Your SQL is basically just a serialization of the data in your new database.
Anything else that you could do, such as calculating the differences from the one database to the other, and then creating a minimal edit list that will make the least possible number of changes must be weighed against the time it will take to write the code to compute the differences, the time it will take to debug the code and convince yourself that it is doing the right thing, and the time it will take to actually run.

    a user is a schema and schema is a user. but when this applies to the user that he become a schema, only if he has got some objects. so we can say while creating the user which dosent contain any objects called simple user account but afterwords when he has got an objects then we can say its a schema as the above user has shown you through the exampleIt is just word-play. There is nothing in like a 'status' indicator to say "USER_A is just a user but USER_B has become a schema". Many people use the terms "user" and "schema" interchangeably, and some very good DBAs will insist this is correct. I don't disagree with them even though I usually try to make the distinction.
    In a typical application, all of the objects (tables, procedures, etc) that implement the app will be owned by a "application schema owner" - a user which exists for the sole purpose of owning the schema. Said user will have no privileges at all .. especially not CREATE SESSION. Except for possible maintenance activity no one ever actually connects as this user. User accounts are then given to actual humans who connect with their own accounts. The accounts have the necessary system and object privileges granted to them - via a role. One could also create a special account (let's call it APP_ADMIN) that is used for maintenance and batch operations within the application.

  • Find difference between date

    I need to know how i can find difference between date
    like Joining date: 01-jan-2009 Today 10-jan-2010 result will be "1 year 10 days"
    I need it in Oracle forms 6i. plz help me...

    Hi,
    In oracle forms you can use
    RESULT :=
    TRUNC ((:date2 - :date1 + 1) / 365)
    || ' year and '
    || MOD (:date2 - :date1 + 1, 365)
    || ' days';
    in sql you can use
    SELECT TRUNC ((:date2 - :date1 + 1) / 365)
    || ' year and '
    || MOD (:date2 - :date1 + 1, 365)
    || ' days'

  • Find Differences between two tables at column level

    Hi,
    I have 2 tables one live table and the other History table..
    If i have to find differences between live table and the latest version in the History table and also find which column got chaanged
    How would i do that for a table which has many columns and i need each column for which the value has changed for a id
    for ex:
      Table 1   (LIve)                           Table 2 (History)
    ID col1     col2    Version               ID       col1     col2    Version
     1   ABC     123     V1                     1       ABCD   123     v2
     2   NBS     1234   V1                     2        NBS     123     V2
    Result set should be 
    Result Set:
    ID col which changed
    1    col1
    2    col2   
    Because the values for that column had been changed
    Except gives me all the differences not just the column level ..

    This is fully covered in the documentation:

    About Packaged Applications
    There is little difference between packaged applications and database applications, other than that packaged applications are supplied by Oracle and database applications are created by you.

    HI
    An entire table can be included in a database view. In this case all the fields of the included table will become fields of the view (whereby you can explicitly exclude certain fields). If new fields are included in the table or existing fields are deleted, the view is automatically adjusted to this change.

  • What is the exact difference between Database Cloning and Database Refresh?

    Hi,
    Can anybody tel me the exact difference between Database Cloning and Database Refresh?
    I Have some conflicts in these topics.
    Thanks
    Rajesh

    Refresh is what it says, "refresh" . You have a main site which would always have the data being inserted into it. There would be another site which would remain some where else . This site needs to be refreshed with the primary site. So you need to do export from the primary, push it to the secondary site and done!

  • Difference between Database, instance and schema

    Hi
    I don't know the clear difference between database, instance and schema.. In the broad sense, everything seems to be the same. If anyone can differentiate between them with some example, that will be of great help.
    Thank you.

    Hi,
    In Oracle, people often do use "database" and "instance" interchangeably, or together as one term: "database instance".
    A "schema" is quite different. A schema is a collection of objects (such as tables, indexes or procedures). Every object belongs to exactly one schema, and every schema is a part of exactly one database. (Names may not be unique, however. For example, your database may have one schema named SCOTT, and another schema named USER1. Each of those schemas may have a table named EMP. The EMP table in the SCOTT schema, or SCOTT.EMP, is not the same as the EMP table in the USER1 schema, or USER1.EMP. A different database, my database for example, may also have schemas called SCOTT and USER1, which are completely independent of the SCOTT and USER1 in your database.)

  • Difference between Database Mirroring and Cloning?

    Hi,
    Can anybody tell me the exact difference between Database Mirrorring and cloning?
    Is database mirroring and multiplexing same?
    Thanks
    Rajesh

    cannot be kept current automatically with the source database It is possible using manually scripted code to automatically update a cloned database to in effect build your own mirrowing process. This is basically a description of home grown Data Guard and is how many sites maintained a ready to use backup prior to Oracle introducing Data Guard.
    The best way to create a clone database today is probably to use the rman duplicate command.
    The clone could be the base for use with a mirrowing process you are setting up or used for other purposes such as providing a consistent frozen snapshot of production for special reporting. It could become the unit test or system test environment or perhaps be used for diaster recovery purposes.
    A clone is a one-time event. Mirrowing is an ongoing process.

  • Difference between Database view and Table

    Hi there,
    Can anyone tell me the difference between Database view and Table.
    Will the Database view query be more faster than a database table?

    Tables and database views can be defined in the ABAP Dictionary.
    These objects are created in the underlying database with this definition. Changes in the definition of a table or database view are also automatically made in the database.
    Data from several tables can be combined in a meaningful way using a view (join).
    You can also hide information that is of no interest to you (projection) or only display
    those data records that satisfy certain conditions (selection).
    Database views implement an inner join. You only get those records which have an
    entry in all the tables included in the view.
    in views db modifications are not possible
    views only contain data at run time
    when they consult the database
    in case of views the join definitions are already sstored in the database itself
    whereas join as open sql is a query to oracle  database as similar select statements
    Views are optimized by SAP and stored in the repository while Joins
    are in reports that needs to be compiled at every execution
    Reward if helps

  • Difference between database design and schema design

    Hi i have visited so many database websites and i found so many people saying we can design a data base for you. Is schema designing and database designing is the same. so many palces i find people saying we have to design data base first in order to create a physical databse. so i am little bit confused. are they same? and also what is the difference between data model and schema?

    > the definition i found for logical data model, physical data model and the definition you
    gave for logical database design, physical database design are the same.
    Not correct. The physical design is the implemetation of the logical design. These two designs are at different levels. Also, the logical design will be the same. irrespective of the RDBMS product use.
    What is incorrect is a designer/architect designing a logical design specifically for Oracle.. or specifically for SQL-Server. A logical design has nothing to do with the RDBMS product (or h/w platforms. app servers, web severs and operating systems used).
    So the logical design will always be the same - it is RDBMS independent.
    The physical design is fully dependent on the RDBMS product used. The same logical design will be implemented as different physical designs for Oracle and for SQL-Server.

    You won't see a difference between these two functions with just a string or other simple data types.  Where you'll see a difference is with clusters and more complex data types that come from the database.  The variants returned by databases can be slightly different than the standard variant.  That is where the Database Variant To Data is needed.  Otherwise, if you are just reading string information, either function will work fine.
