Bingo.

Although in my PHP code I always use explicit (to_date) date conversion in any SQL, it appears that querying a view that has been successfully compiled using implicit date conversion causes the problem.

Odd that PHP and/or AdoDB and/or OCI appears to be attempting to "revalidate" the view when simply selecting from it. Don't know if this is version specific or even at what stage (PHP/AdoDb/OCI/Oracle Client) it's kicking in.

Just recompiled the view with explicit date conversion and moving on, no time to chase further.

Thanks Andy and Erwin for your pointers, owe you one.
