Re: [SQL] delete with cascade

I was reading the manuals on DELETE and I saw this:

By default DELETE will delete tuples in the table specified and all its
sub-tables. If you wish to only update the specific table mentioned, you
should use the ONLY clause.

I just don't understand what sub-tables means. Does it mean that it will
delete rows on other tables which are referenced with a FOREIGN KEY to the
row which will be deleted?

Saludos... :-)
