Local sequence cannot be used in LINQ to SQL implementations of query operators except the Contains operator

I am getting this error on a webpage, on a Microsoft Report Viewer component:

An error has occurred during report processing. Local sequence cannot be used in LINQ to SQL implementations of query operators except the Contains operator.

My code:

public static IEnumerable GetUrunMiktarliDetayli()

    Baglanti();
    List开发者_StackOverflow社区<StokEnvanteriSatiri> urunListesi = new List<StokEnvanteriSatiri>();
    urunListesi = GetUrunListesiDoldur();

    var urunStok = from urunS in urunListesi
                   select new
                   {
                       urunS.AcilisMiktari,

This method GetUrunListesiDoldur() basically returns a List<StokEnvanteriSatiri> list of StokEnvanterSatiri, I know the problem is that I am trying to join an in-memory list with an SQL table.

Is there any way to handle this?

I basically reversed the join and it worked

var urunMD = from urunStokbilgileri in urunStok
             join urun in db.TBLP1URUNs
                       on urunStokbilgileri.UrunNo equals urun.ID
             join kategori in db.TBLP1URUNKATEGORIs
                       on urun.KATEGORIID equals kategori.ID
             ......

You have to force LINQ to evaluate the second join locally. You can do this:

var urunMD = (from urun in db.TBLP1URUNs
                 join kategori in db.TBLP1URUNKATEGORIs
                               on urun.KATEGORIID equals kategori.ID).AsEnumerable()
             .Join( [...] )

---

Rewrite your urunMD query to run in two parts. Use a Contains operator to filter the initial records in TBLP1URUNs and then return the database data only. Then use a separate LINQ-to-Objects query to combine the database data from TBLP1URUNs with the in-memory data in urunStok.
