可以像這樣寫成的LINQ to SQL：

SET CustomerName = t2.Name 
FROM Table1 t1 JOIN Table2 t2 
ON t1.TableID = t2.TableID

var result = from t1 in context.Table1 
       join t2 in context.Table2 on t1.TableID = t2.TableID 
       select new {t1, t2}; 

result.ToList().ForEach(i => i.t1.CustomerName = i.t2.Name); 
context.SubmitChanges();
