Hello,
While I can't answer my question, I am afraid I did not understand your
intentions either. The update you mentioned may not return consistent
results, isn't it? You are not ordering the data in any particular manner
and there is no unique column either. So the result of the update will
depend on the order in which the data is fetched - which need not be
consistent?
If data is fetched as
I J
---------- ----------
1 2
1 3
1 4
update will result in one set of data.
1 2
1 5
1 7
If the query returns
I J
---------- ----------
1 4
1 2
1 3
the result of the update will be different?
1 4
1 6
1 5
Regards,
Jayadevan
