Excel/CSV data to Oracle Tables and compare data

7 New Member
I have two excel files(say XL1, XL2) with same structure.
1) Part of XL1 data may exist in XL2 with few column values changed(modifie d field values)
2) Few records of XL1 may be delted in XL2(deleted)
3) New records may be added in XL2(newly added)

I need to load two excel into two different tables in the same (Oracle) database and compare the same and need to give output as
a)Modified records(Primary _Key_Field_Valu e, XL1 value(old value), XL2 value(New value)
b)New(Inserted) records which are present in XL@ but not in XL1
c)Old(Deleted) records which are present in XL! but not in XL2.

Here is oracle's documentation on the pivot and unpivot syntax: http://www.oracle-base.com/articles/...tors-11gr1.php.

You will want to use the examples in there to unpivot your two tables. That's the first step.

We are running SQL Server 2000 SP3. We have linked servers in use that we use to access Oracle tables. Recently the claim has been made that you can access Oracle tables from within SQL Server without using a Linked Server. I searched Books Online using keywords: linked, remote, and Oracle and did not find anything. A search of the newsgroup archives found only entries related to using Linked Servers.
