Full Column Match and I1 Access on SQL with Correlated Sub-Queries Containing Column Expressions and Supporting IoE

Some queries with column expressions - DATE(A1.EFCTV_TS) <= DATE('04/05/2020') for example, and an Index on Expression to support the expression are achieving I1 access while others are not. It appears this is because of how the query is currently parsed. Since transformation is done prior to costing, sometimes the transformation is not done to make sure that the index is still considered for costing.

    Thank you for submitting this Aha! Idea. Db2 for z/OS development reviewed it and determined there isn't sufficient context to evaluate what situations that you are referring to. Which examples do & do not result in I1 access based upon your experience? Is there a case where this was reported to Db2? Please provide more information so our review of this idea may continue.

    Thank you
