I create two index on two tables
Like table A create index on the foreign key of the table B.
But when i make an explain plan i receive a full table scan
Why the index they not use...
I pass a script analyze table before.
my sql is (select a.id.b.id from table_a, table_b
where table_a = table_b;)

Thanks
