Igor,
I think it should be:
select SUBSTR(hint, INSTR(hint,' ') + 1, LENGTH(hint) - INSTR(hint,' ')
-
1),
count(*)
from dba_outline_hints
where hint like '%INDEX%'
GROUP BY (SUBSTR(hint, INSTR(hint,' ') + 1, LENGTH(hint) - INSTR(hint,'
')
- 1));
--List of indices not used:
Select index_name
from user_indexes
where index_name not in (
Select distinct SUBSTR(hint, INSTR(hint,' ') + 1, LENGTH(hint) -
INSTR(hint,' ') - 1)
from dba_outline_hints
where hint like '%INDEX%'
)
(INSTR changed)
Rob
