SQL:HAPUS data dari tabel referensi diri dalam urutan tertentu

Coba

ALTER TABLE [group] NOCHECK CONSTRAINT ALL
go
DELETE FROM [group] WHERE [groupId] <> '00000000-0000-0000-0000-000000000000'
go
ALTER TABLE [group] CHECK CONSTRAINT ALL
go

Jika tabelnya besar, ini mungkin pilihan yang bagus.

select * into #temptable from [group] WHERE [groupId] = '00000000-0000-0000-0000-000000000000'
go
truncate table [group]
go
select * into [group] from #temptable
go
drop table #temptable
go
