आप अपनी ईमेल सूची को XML में बदल सकते हैं और फिर .nodes . का उपयोग करके XML को क्वेरी कर सकते हैं और .value ।
declare @T table
(
ID int,
Emails varchar(100)
)
insert into @T values
(1, '[email protected], [email protected]'),
(2, '[email protected], [email protected]')
select T.Email, count(*) as [Count]
from (
select X.N.value('.', 'varchar(30)') as Email
from @T
cross apply (select cast('<x>'+replace(Emails, ', ', '</x><x>')+'</x>' as xml)) as T(X)
cross apply T.X.nodes('/x') as X(N)
) as T
group by T.Email
परिणाम:
Email Count
------------------------------ -----------
[email protected] 1
[email protected] 2
[email protected] 1
