How to move a column within a table?

Hi All!
Is it possible in Oracle 9i to move a column within a table? For instance, I have a table
ID1 ID2 ID3 SRC_ID1 SRC_ID2 SRC_ID3
and I want to add one more column ID4. So, I can do it like this:
ALTER TABLE MY_TABLE
ADD ID4 NUMBER(18);
In this case, the column will be added to end of the table but I want to move the column on the position after ID3. So, my question is, is it possible to move a column within a table? And if yes, how I can do it?.
Any help will be appreciate.
With best regards,
Andrej Litowka.

Hi,
Actually speaking it makes no difference where a column is placed in the table. The select clause is the one that decides on how to display the data. But still if you want to store it next to a particular column then there are 2 options...
1. Rename <tname> to <tname_1>;
Create view <tname> as select <cols> from <tname_1>;
The above option is useful in case of selects. In case of DMLs it will have to do a little more work by going and firing the same on the actual underlying table.
2. Rename <tname> to <tname_1>;
Create table <tname> (<new col order with the new col>);
Insert into <tname> (select <col order> from <tname_1>);
This option seems to be better than the first one.
Hope this helps you.
Regards,
DJ

How to Delete a Column in Internal Table

Hi All,
Does any one know ,How to Delete a Column in Internal Table?

Hi,
For deleting the column in the internal table, you have to eliminate the field which you want to delete.
loop at itab into wa.
move corresponding wa to wa1.
append wa1 to itab1.
clear wa1.
clear wa.
endloop.
wa1 is the workarea without the field which you want to delete.
itab1 is the internal table which consists of the deleted column.

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)

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)

Are you connecting to these tables from Essbase with a load rule / ODBC? Using Studio? Using Integration Services? Any Drill-Through reporting set up?
