The 'best' consulting jobs: follow the guys who think "SQL is SQL. If I
wrote it for SQLServer, it'll run on Oracle." Which might be true for
individual SQL statements but is a horrible assumption when dealing with
multi-statement flows and multi-user concurrent apps.
Since 'they' don't understand how it works 'under the covers', the code
will often use lots of techniques which kill performance in Oracle.
