Penso che tu abbia bisogno di un modo più sofisticato per verificare che i Models i valori delle colonne sono corretti a causa degli spazi dopo il punto e virgola. Inoltre, se devi elaborare i Models valori di colonna che contengono più di dieci parti, avrai bisogno di una sequenza di numeri più lunga. Uso INFORMATION_SCHEMA COLUMNS
tavolo per questo. Puoi anche creare una tabella ausiliaria per questo.
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, '-', ''));
