TO_DATE function problem

Question

Hello World,
I was using To_date function to update a record, and the year it is updating is getting messed up.I tried like this:
update MyTable set created_dt =
to_date('99-9-19','yy-mm-dd')
where rec_id = 106
Then the year in the database shows 2099 instead of 1999.This is happening when I was trying to update year upto 50. i.e,if I try to update with ,
to_date('50-9-19','yy-mm-dd') , it updates the year to 2050.
But if I update with year 49, it updates 1949.
When I update using the following statement,it is updating fine
update W2_01_REC set created_dt ='19-sep-99' where rec_id = 106.
With the above statement it updates the year to 1999
Could anybody tell me why it is updating differently with different statements as above.
And where we can set the date break point for such updates ot inserts in database.
Thank you in advance

Dear Gopal,
See if the following solves your problem (note the change in the format model specification):
update MyTable set created_dt =
to_date('99-09-19','RR-MM-DD')
where rec_id = 106 ;
Best of luck!
