यदि आप एक अद्यतन विवरण चाहते हैं तो आप लगभग उसी संरचना का उपयोग कर सकते हैं:
With Dups As
(
Select Id, Name
, Row_Number() Over ( Partition By Name Order By Id ) As Rnk
From Table
)
Update Table
Set Name = T.Name + Case
When D.Rnk > 1 Then ' (' + Cast(D.Rnk As varchar(10)) + ')'
Else ''
End
From Table As T
Join Dups As D
On D.Id = T.Id
