Jeg tror, du har brug for en mere sofistikeret måde at bekræfte, at Models
kolonneværdier er korrekte på grund af mellemrum efter semikolon. Desuden, hvis du har brug for at behandle Models
kolonneværdier, der indeholder mere end ti dele, skal du bruge en længere talrække. Jeg bruger INFORMATION_SCHEMA COLUMNS
bord til dette. Du kan også oprette en hjælpetabel til dette.
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 t.part REGEXP '^[0-9]+(-[0-9]+)*$' AND
N.n <= LENGTH(t.part) - LENGTH(REPLACE(t.part, '-', ''));
