| | The point...has anybody else experienced similiar problems with queries which fully quailify a table's PI; however, due to the
existence of multiple in-lists, the Optimizer opts for a full-table scan instead of a PI retrieveal? | |
In a word, yes. I've noticed it most recently when providing some columns of a primary index as literals and the rest as values
from a joined table. The optimizer ignores the index.
