,[PolicyEndDate]

,[policyDate]

,[PolicyNo]

,[source]

,[policttype]

into #Candidates

from Policy WITH (nolock)

select

[ContactID]

from #Candidates e

inner join #Candidates s

ON

1. e.contactid = s.contactid

AND e.policytype = s.policytype

AND e.source = s.source

WHERE

ABS(DATEDIFF(DAY,s.PolicyDate , e.PolicyEndDate)) < 30

AND

(e.Policy <> s.Policy)

GROUP BY
