Oracle Solution for Error ora-01451
ORA-01451: column to be modified to NULL cannot be modified to NULL
What triggered the Error:
the column may already allow NULL values, the NOT NULL constraint is part of a primary key or check constraint.What should we do to fix it:
if a primary key or check constraint is enforcing the NOT NULL constraint, then drop that constraint.
