Hi,

I am having a transaction table , which has got 75 columns.
In future,more columns will be added to the table based on the requirements.
It has got more than two million records.

Is there any way to add the new columns to a new table which will be an extension of the
existing table ?

I have tried of creating a new object with one-to-one relation, but the problem is,
for the existing two million records, the value will be null.

Thanks in advance.
