Hi everbody!

In SQL Server i do this:
1) export some tables from database1
2) create a new database 'database2'
3) i import the exported tables in database2
4) i run a query like:

select * from database1.dbo.table
except
select * from database2.dbo.table

(this to check if there are some things that don't match, this is a fictive example, i do know that when i follow these steps, there will be no differences between the 2 tables)

Now my question is, how do i do that in oracle?
Do i need to create a new database or can i do the same thing with a different SCHEMA or what?

The same way but using Oracle tools (exp/imp) and SQL syntax.

Basically, it is the same job, just change MS SQL Server terminology to Oracle's one. In another words, it isn't a "database" but a "schema".

1. export some tables from schema1
2. create a new USER (using the CREATE USER command)
3. import exported tables into a new user's schema
4. grant privileges (SELECT might be enough) in order to be able to view data stored in another user's schema
5. write your queries and compare records

how can i import the exported tables into a new user's schema in OEM? When i do it through the import from export files option,
the source schema in the re-map table is empty

I wouldn't know. I prefer command line Export and Import utilities.

I may not be reading this question correctly, but if you just want to compare the DATA between two tables, then you can use the set operators such as MINUS.

And if you just want to copy the data of a table you can do things like create table newtable as select * from oldtable.
