Subject: Forcing SQL query to use 2 index hints
Hello all,
I am attempting to force a query to use 2 index hints, but am not
having
any luck with finding the correct syntax.
The query works, and if I add 1 index hint, the explain plan output
shows
that it is using the index I specify. However, I need it to use 2 hints:
What is the correct syntax?
SELECT /*+ index(a index_A, b index_B) */ column1,column2,column3,column4
from table_a a,table_b b
where a.something = b.something;
(The above is not using "index_B" .... how do I force it to use
index_B??
Only index_A is being used. What is the correct syntax?)
Thank you!!!!!
