  When use alter table to add a coulmn --> ABC char(2) not null with default, will Teradata insert "blank" to each existing row, or just modify the table header instead?  



I write:

I think it will insert the blank to every row and is obvious from the below query after issuing the ALTER TABLE on t1.

sel char2hexint(abc),a,b,abc from t1;

        Char2HexInt(ABC)        a       b       ABC
        2020                    1       1
        2020                    1       11
        2020                    1       111

Thanks, Vivek.
