sql 在MYSQL中，我们希望有一个名为“virtual”的独立数组。我们想知道那些不在另一个表的结果中的行。

SELECT
  `virtual`.`psc`
FROM
  ( SELECT
      11005 AS `psc`
    UNION SELECT
      15400 AS `psc`
    UNION SELECT
      19009 AS `psc`
# ...
    UNION SELECT
      79813 AS `psc` )
    AS `virtual`
WHERE
  `virtual`.`psc` NOT IN (
    SELECT
      `ceska_posta_zip`.`psc`
    FROM
      `ceska_posta_zip`
  )
