I have to renumber the emplid in all the tables. I have written a program to find out the tables which has emplid columns and then update those with new number. Some of the table has lot of rows. I ran the program and found that after updatinf about 13256 rows out of 19000 rows in one table it stops. ANy reason for this? I am not an oracle man to find about whether it is a table space issue like Undo etc. Any help is appreciated.
