Just to qualify that, I mean that when I’m messing around queries I quite often comment out bits, comment back in, etc. So, this means I just have to comment out the references in the FROM and WHERE not the actual subquery above.

I would rather see the error message as this would alert you to either dead code or a mistake, and force you to resolve it.

I’ve looked into this before via a 10053 and it’s clear that the unreferenced query is eliminated but not which query transformation is the culprit – they all say bypassed or not valid

From 10053:
..
Final query after transformations:******* UNPARSED QUERY IS *******
SELECT “DUAL”.”DUMMY” “DUMMY” FROM “SYS”.”DUAL” “DUAL”

So bug or feature? Interesting.

From a practical, development perspective, I like that it’s disappeared.

Thanks Alex, don’t have an 11.1 here to check it.

The same is true for 11.1 (http://technology.amis.nl/blog/4252/subquery-factoring-in-oracle-11g) As far as I’m concerned it’s a feature, the part which is not required for the execution of the query is eliminated.
