Analiza danych pól MySQL

Myślę, że potrzebujesz bardziej wyrafinowanego sposobu sprawdzenia, czy Models wartości kolumn są poprawne ze względu na spacje po średnikach. Dodatkowo, jeśli potrzebujesz przetworzyć Models wartości kolumn, które zawierają więcej niż dziesięć części, będziesz potrzebować dłuższej sekwencji liczb. Używam INFORMATION_SCHEMA COLUMNS tabela do tego. Możesz również utworzyć do tego tabelę pomocniczą.

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, '-', ''));
