MySQL-fältdataanalys

Jag tror att du behöver ett mer sofistikerat sätt att verifiera att Models kolumnvärdena är korrekta på grund av mellanslag efter semikolon. Dessutom, om du behöver bearbeta Models kolumnvärden som innehåller mer än tio delar, behöver du en längre talföljd. Jag använder INFORMATION_SCHEMA COLUMNS bord för detta. Du kan också skapa en extra tabell för detta.

SELECT
  CONCAT(
    IF(N.n = 0, '', LEFT(t.part, 2)),
    SUBSTRING_INDEX(
      SUBSTRING_INDEX(t.part, '-', N.n + 1), '-', -1
    )
  ) AS part, t.isHD, t.ID, t.GroupNumber, t.PartNo, t.Models
FROM Numbers AS N CROSS JOIN (
  SELECT
    SUBSTRING_INDEX(
      SUBSTRING_INDEX(t.part, ' ', N.n + 1), ' ', -1
    ) AS part, t.isHD, t.ID, t.GroupNumber, t.PartNo, t.Models
  FROM Numbers AS N CROSS JOIN (
    SELECT
      SUBSTRING_INDEX(
        SUBSTRING_INDEX(t.part, ';', N.n + 1), ';', -1
      ) AS part, t.isHD, t.ID, t.GroupNumber, t.PartNo, t.Models
    FROM Numbers AS N CROSS JOIN (
      SELECT
        REPLACE(
          SUBSTRING_INDEX(
            SUBSTRING_INDEX(t.part, 'LHD', N.n + 1), 'LHD', -1
          ), ',', ''
        ) AS part, IF(N.n > 0, 1, t.isHD) AS isHD,
        t.ID, t.GroupNumber, t.PartNo, t.Models
      FROM Numbers AS N CROSS JOIN (
        SELECT
          SUBSTRING_INDEX(
            SUBSTRING_INDEX(p.Models, 'RHD', N.n + 1), 'RHD', -1
          ) AS part, IF(N.n > 0, 2, 0) AS isHD,
          p.ID, p.GroupNumber, p.PartNo, p.Models
        FROM Numbers AS N CROSS JOIN parts_listing AS p
        WHERE p.Models REGEXP '[[:<:]]([LR]HD,? +)?[0-9]+(-[0-9]+)*[[:>:]]' AND
              N.n <= (LENGTH(p.Models) - LENGTH(REPLACE(p.Models, 'RHD', ''))) / 3
      ) AS t WHERE N.n <= (LENGTH(t.part) - LENGTH(REPLACE(t.part, 'LHD', ''))) / 3
    ) AS t WHERE N.n <= LENGTH(t.part) - LENGTH(REPLACE(t.part, ';', ''))
  ) AS t WHERE N.n <= LENGTH(t.part) - LENGTH(REPLACE(t.part, ' ', ''))
) AS t WHERE t.part REGEXP '^[0-9]+(-[0-9]+)*$' AND
             N.n <= LENGTH(t.part) - LENGTH(REPLACE(t.part, '-', ''));
