Hi,



I have created view which uses UNION on two tables. Table1 has more than 3.4
million rows and Table2 is approx. 10% of Table1 size. When I select
count(*) from Table1, query executes 26 minutes an temporary tablespace
usage does not increase. When I select count(*) from query with UNION,
temporary tablespace usage is increasing till query fails due to
insufficient space.



Oracle version is 7.3.4 on HP-UX



Any ideas?



Primoz
