Hi All!
I need to make function which emulates table and returns setof columns
of this "table"
for example, i'm making query: "SELECT * FROM my_table(user_id)"
and function
CREATE OR REPLACE FUNCTION my_table (integer)
RETURNS setof text
AS '
DECLARE
check_date date;
max_date date;

Is there a third table, perhaps Authors?

It's a bit complex.
I have two tables. "Books" and "Book_Authors" (which links between
book_id and author_id).
Book_authors has a foreign key on book_id to the Books table. On key
violation it is set to delete the rows (if a book is deleted, it
should't be linked to any authors).
In Book_Authors

What problem are you trying to solve?

I noticed that when you do a constraint and tell it "cascade on
delete", it will do so only AFTER that the source is deleted. Can I
tell it somehow to cascade BEFORE the source is gone?
