Dialect
For example, for Oracle, generates
SELECT 1 AS FOO, 'a' AS BAR FROM dual UNION ALL SELECT 2 AS FOO, 'b' AS BAR FROM dual
For ANSI SQL, generates:
VALUES (1, 'a'), (2, 'b')

public boolean requiresOrderByAlias()
Dialect
For example, in such a dialect,
SELECT x FROM t ORDER BY x + y
would be illegal, but
SELECT x, x + y AS z FROM t ORDER BY z
would be legal.
MySQL, DB2 and Ingres are examples of such dialects.
