Creating LINQ to SQL for counting a parameter
- by Matt
I'm trying to translate a sql query into LINQ to SQL. I keep getting an error "sequence operators not supported for type 'system.string'" If I take out the distinct count part, it works. Is it not because I'm using the GROUP BY?
SELECT COUNT(EpaValue) AS [Leak Count], Location, EpaValue AS [Leak Desc.]
FROM ChartMes.dbo.RecourceActualEPA_Report
WHERE (EpaName = N'LEAK1') AND (Timestamp) '20100429030000'
GROUP BY EpaValue, Location
ORDER BY Location, [Leak Count] DESC
Dim temp = (From p In db2.RecourceActualEPA_Reports _
Where (p.Timestamp = str1stShiftStart) And (p.Timestamp < str2ndShiftCutoff) _
And (p.EpaName = "Leak1") _
Select p.EpaName.Distinct.Count(), p.Location, p.EpaValue)
