Answer / yuvaevergreen
RI is created using creat or alter statement. RI can be
created for a populated table also. In that case the error
is moved to a error table. After clearing out the errors,
the rows can be inserted in to child or parent table.
In teradata, Soft RI is one feature, where the checking is
not done for every update or insert. It is created by using
no check option while using create statement.
