Try something like this:
var cte = Table1.Concat( Table2 ); var query = cte.Select( t => new { t.column1, t.column2, t.column3 } ).Append( new { column1 = cte.Sum( t => t.column1 ), column2 = cte.Sum( t => t.column2 ), column3 = cte.Sum( t => t.column3 ) } ); var results = query.ToList( );
In case of Entity Framework, use corresponding stuffs instead of Table1 and Table2.

var query = ( from shf in db.ShitjaFaturims where shf.Data >= dpDate.Value && shf.Data <= dpDate1.Value group shf by new { shf.NRFA, shf.Data, shf.KlientiID } into g select new { g.Key.NRFA, VleraLiruarTVSH = (decimal?)g.Sum(p => p.VleraLiruarTVSH), VleraPaTVSH = (decimal?)g.Sum(p => p.VleraPaTVSH), VleraTVSH = (decimal?)g.Sum(p => p.vleraTVSH), VleraMeTVSH = (decimal?)g.Sum(p => p.VleraMeTVSH), VleraTVSH8 = (decimal?)g.Sum(p => p.VleraTVSH8), VleraMeTVSH8 = (decimal?)g.Sum(p => p.VleraMeTVSH8), Totali = (decimal?)g.Sum(p => p.Totali) } ).Concat ( from f in db.Faturats where f.Data >= dpDate.Value && f.Data <= dpDate1.Value group f by new { f.NRFA } into g select new { NRFA = g.Key.NRFA, VleraLiruarTVSH = (decimal?)g.Sum(p => p.VleraLiruarTVSH), VleraPaTVSH = (decimal?)g.Sum(p => p.VleraPaTVSH), VleraTVSH = (decimal?)g.Sum(p => p.vleraTVSH), VleraMeTVSH = (decimal?)g.Sum(p => p.VleraMeTVSH), VleraTVSH8 = (decimal?)g.Sum(p => p.VleraTVSH8), VleraMeTVSH8 = (decimal?)g.Sum(p => p.VleraMeTVSH8), Totali = (decimal?)g.Sum(p => p.Totali) } ).Concat (from query in (from sh in query where sh.Data >= dpDate.Value && sh.Data <= dpDate1.Value select new { sh.VleraLiruarTVSH, sh.VleraPaTVSH, sh.vleraTVSH, sh.VleraMeTVSH, sh.VleraTVSH8, sh.VleraMeTVSH8, sh.Totali, NRFA = "x" }) group query by new { query.NRFA } into g select new { NRFA = "Totali:", VleraLiruarTVSH = (decimal?)g.Sum(p => p.VleraLiruarTVSH), VleraPaTVSH = (decimal?)g.Sum(p => p.VleraPaTVSH), VleraTVSH = (decimal?)g.Sum(p => p.vleraTVSH), VleraMeTVSH = (decimal?)g.Sum(p => p.VleraMeTVSH), VleraTVSH8 = (decimal?)g.Sum(p => p.VleraTVSH8), VleraMeTVSH8 = (decimal?)g.Sum(p => p.VleraMeTVSH8), Totali = (decimal?)g.Sum(p => p.Totali) } );
Thank you for your Help because doesn't work.
Only grand totals are wrong?

Hi DataRks,
First, concat is the Linq equivalent of union all in SQL.
And Viorel provide a coed example to convert from SQL query to LINQ.
Then about your Linq statement,you should use the existing fields in the table for grouping instead of using the keyword new.
