Sebenarnya Anda hampir mencapai tujuan Anda, Anda hanya perlu menggunakan metode node() untuk membagi baris Anda dan kemudian mendapatkan nilai:
select
s.SqmId,
m.c.value('@id', 'varchar(max)') as id,
m.c.value('@type', 'varchar(max)') as type,
m.c.value('@unit', 'varchar(max)') as unit,
m.c.value('@sum', 'varchar(max)') as [sum],
m.c.value('@count', 'varchar(max)') as [count],
m.c.value('@minValue', 'varchar(max)') as minValue,
m.c.value('@maxValue', 'varchar(max)') as maxValue,
m.c.value('.', 'nvarchar(max)') as Value,
m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)
