In a database there are existing a foreign key. The fieldtype is Varchar2.
Now one entry of the foereign key shall be changed, because of a misspelling
in the reference table and therefore also in the detail tables.



I thought I have to disable the foreign key, change the value and enable the
foreign key again.



Now someone told me that there is also another way via a trigger on the
reference table. Is that true?



Regards


Nicolas
