Linq to SQL Left Outer Join Help

I have  

Dim query = From pl In dc.Places
                        Join rp In dc.RoundProps
                        On pl.Id Equals rp.PropId

Open in new window


I need all records in Places with no matching records in RoundProps.

Any ideas ?

so try this if this works?

Dim query = From pl In dc.Places
                        Join rp In dc.RoundProps
                        On pl.Id Equals rp.PropId into t
                       from rp in t.DefaultIfEmpty()
                       where rp Is Nothing

It doesn't like 'into T'  end of statement expected

This line of code

On pl.Id Equals rp.PropId into t

Open in new window

should be
On pl.Id Equals rp.PropId into t = Group

Open in new window

I'm still getting the same error with t= Group

Hi Watersider;

Try running this query. It should work as long as pl.Id and r.PropId are not Null / Nothing.

Dim query = From pl In dc.Places            
            From rp In dc.RoundProps.Where(Function(r)  r.PropId  = pl.Id).DefaultIfEmpty()
            Where rp Is Nothing
            Select pl
