Answer Posted / manivasan.s
You cannot TRUNCATE a table that has any foreign key
constraints. You will have to remove the contraints,
TRUNCATE the table, and reapply the contraints.
You can DELETE any row that will not violate a constraint,
while leaving the foreign key or any other contraint in place.
