Sql不在Linq問題

Question

我有這個SQL查詢。我可以將大部分查詢轉換爲linq，但我不明白如何在此特定查詢中實現「不在」部分。這裏是我的查詢：

SELECT d.processid,d.name,t.test_name 
FROM dc_tp_tprocess d 
left outer join dc_tp_tprocedured pd on pd.processid=d.processid 
left outer join dc_tp_test t on t.procedureid=pd.procedureid 
where d.active='Y' and t.testid=1 
        and d.processid not in (1,2,6,8,9,10) 
order by t.testid,d.processid 

Answer 1

就像這樣的：

int[] tmp=new int[]{1,2,6,8,9,10}; 

var query=from d in dc_tp_tprocess 
      join pd in dc_tp_tprocedured on d.processid equals pd.processid into leftGroup1 
      from pd in leftGroup1.DefaultIfEmpty() 
      join t in dc_tp_test on pd.procedureid equals t.procedureid into leftGroup2 
      from t in leftGroup2.DefaultIfEmpty() 
      orderby t.testid,d.processid 
      where d.active=="Y" && t.testid==1 && !tmp.Contains(d.processid) 
      select new {d.processid,d.name,test_name=t==null?"":t.test_name};
