bagaimana cara menulis kueri ini di linq (vb.net)?
select B.Name
from Company B
group by B.Name
having COUNT(1) > 1
Jawaban:
Seperti ini:
from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key
Atau, menggunakan sintaks metode:
Company
.GroupBy(c => c.Name)
.Where(grp => grp.Count() > 1)
.Select(grp => grp.Key);
Untuk siapa pun yang ingin melakukan ini di vb (seperti saya dan tidak dapat menemukan apa pun)
From c In db.Company
Select c.Name Group By Name Into Group
Where Group.Count > 1
Group By
is after the Select
clause di VB.

var unmanagedDownloadcountwithfilter = from count in unmanagedDownloadCount.Where(d =>d.downloaddate >= startDate && d.downloaddate <= endDate)
group count by count.unmanagedassetregistryid into grouped

select new
{
UnmanagedAssetRegistryID = grouped.Key,
Count = grouped.Count()
};
