This setting controls the rules dealing with how column names are generated
in select statements.
Administrator rights are required to execute this command, as it affects all
connections. This setting is not persistent.
Emulation settings can be appended to the database URL:
""jdbc:h2:test;COLUMN_NAME_RULES=EMULATE=ORACLE30""
It is not recommended to use overly restrictive settings as system
columns can accidentally get their identifiers truncated leading to
undefined behavior.
