使用包含递归CTE的多个CTE。
WITH CTE AS
(
SELECT
ROW_NUMBER() OVER (ORDER BY (SELECT 0)) AS rn,
t.v.value('.','nvarchar(max)') as value
FROM @htmlXML.nodes('div/table/tr[position()=(5,8,16,24)]/td/div/table/tr/td') as t(v)
),
COMPATS AS (
select CTE.value as ComCode, min(FITMODEL.rn) as rn_fitmodel
from CTE
join (select rn from CTE where value = 'Fit Model') FITMODEL
on (FITMODEL.rn > CTE.rn)
where CTE.rn in (select rn+1 from CTE where value = 'Compatible Code')
GROUP BY CTE.value
),
RECURSIVE_CTE AS (
select ComCode, CTE.rn, CTE.value
from COMPATS
JOIN CTE ON (COMPATS.rn_fitmodel + 1 = CTE.rn)
UNION ALL
select RECURSIVE_CTE.ComCode, CTE.rn, CTE.value
from RECURSIVE_CTE
JOIN CTE ON (RECURSIVE_CTE.rn + 1 = CTE.rn AND CTE.value <> '')
)
SELECT ComCode, value as ComPart
FROM RECURSIVE_CTE
ORDER BY ComCode, rn;
你可以这样做'TR [位置（）=（5,8,16,24）]'，而不是工会的XPath的。你应该添加你期望的结果。因为我猜测一个'max（ROW_Numbers）'为变量获取单个值不是一个好的解决方案。 – LukStorms
