I had a table STUDENT_TB, which had column STUDENT_ID, NAME, AGE. I added a column with a following command :-
alter table STUDENT_TB add DOB TIMESTAMP NOT NULL DEFAULT CURRENT TIMESTAMP
as for the DOB column i didn't wanted it to be null. Now i need to remove that default constraint.
I tried searching but not got any success.
Regards.
