Subsonic3 LINQ Left Outer Join
题
I am using Subsonic3 and would like to get a Left Outer Join between two tables. Here is the tested SQL
SELECT a.*
FROM vwVendor a
LEFT OUTER JOIN dbo.pubvenmap b
on a.vend_no = b.vend_no
where b.vend_no is null
I am stuck at
Dim vendors = From v In vwVendor.All()
Join m in pubvenmap.All() On v.vend_no Equals m.vend_no
UPDATED I also tried the following
Dim vendors = New SubSonic.Query.Select(SubSonic.Query.Aggregate.GroupBy("vend_no")).From(Of vwVendor).LeftOuterJoin(Of mac_pubvenmap)().ExecuteTypedList(Of vwVendor)()
but get the error
A first chance exception of type 'System.InvalidOperationException' occurred in SubSonic.Core.dll
I am using Visual Studio 2010 and .NET 4.0...could this be the problem?
