INCLUDE ROWID VALUE IN THE TABLE

I created a table as
Create table table1 (col1   varchar2(10),
                           col2    number(5),
                          table1_rowid     rowid),
primary key is col1

I Want when I insert new row then the column table1_rowid must contains value of rowid of the same row. then how I can do that, what action and steps I have to do, I know that I have to create a trigger after insert of each row, but what is the plsql procedure I have to do.   Please can you provide me with cleared solution?

Tanks in advance

Don't bother - the row already has ROWID to do that, why try to duplicate it?  In any case, it wouldn't be trivial to do because until the row has been inserted it doesn't have a ROWID.  And to avoid the mutating table error you'd need 2 triggers: one AFTER INSERT FOR EACH ROW to store the ROWIDs in a package collection, and another AFTER INSERT (without FOR EACH ROW) to loop through the rows in the collection and issue this very silly and pointless update:

UPDATE table1 SET table1_rowid = ROWID
WHERE ROWID = rowid_collection(index);

Really, just don't do it!

As andrew says, what is the point?

Once you have found the record with whichever query you have, then tha actual rowid is current. Rowids can change as well, when you do partition switches, and other physical file maintenance.

Not sure what happenes when you rebuild the indexes, the rowid might also change then, as they are not physically held ont eh database.
