Hello,
I use PostgreSQL 8.1 and I would like create and index on a table's
field with a sort condition on this field.
For example, I have a table named books and I want create an index on
the fields title and id_book with an order by id_book descendant.
I know how to create the index without this condition :
create index book_index on books(id_book, title);
But, I don't know to create this index with the sort condition.
Someone has an idea ?
Thanks to help me.
Sylvain.
