Dag H. Wanvik commented on DERBY-6527:
--------------------------------------
One little item: This line
> When a value in a column of the dependent table is deleted, and that value is
> part of a foreign key, NO ACTION is the implicit delete rule.
reads a bit odd. We don't delete individual columns in a row, but we can modify
one or more columns that are part of the FK in a dependent table row, in which
case, the NO ACTION semantics apply. If the entire row is deleted, there is no
FK to check any more.
