i just have a question, i have a program that inserts data on my
oracle 8i, database....
however let us say that i want to insert data on a table and it
means that i have to insert a data to a field that is a foreign key....
from my understanding since it is a foreign key, data in it must
already exist in another table, how can i somehow check if the
data that i will insert in the Foreign key field already exist in another
this is for referential integrity issue
