Question

How can I join views using sql? I’m using Oracle at the moment?

Sql view 1

CREATE VIEW florence_staff AS
SELECT *
FROM staff
WHERE libname ='florence'

Sql view 2

CREATE VIEW alexandria_staff AS
SELECT *
FROM staff
WHERE libname ='alexandria'

I’m doing this to check if the fragmentation is correct, if you get what i mean. Thanks :))

Answer 1

These will be distinct result sets as the libname is different so use UNION ALL rather than UNION

SELECT * FROM florence_staff
UNION ALL
SELECT * FROM alexandria_staff
