Hi,
I have a table of categories (it's pseudo-sql...) :
CATEGORIES
( id_category PRIMARY KEY, id_category_parent (FOREIGN KEY ? CONSTRAINT ??) , cat_text
)
There is recursivity : id_category_parent is -1 (= no parent cat) or the
id_category of a category in this table.
What is the SQL statements to create such a table so that when you delete a
category, all sub-categories
are automatically deleted ?
I've tried many things like CONSTRAINT... but the query fails !
Thanks !
