I'd like to point out that while most databases are mostly SQL-92 compliant, INFORMATION_SCHEMA.TABLES is not implemented in Oracle 126.96.36.199 (the latest patch release, that I'm aware of).
I don't know if any other database implements this or not.

Please remember that I'm crufty and crochety. All opinions are purely mine and all code is untested, unless otherwise specified.
