特定のフィールドが複数の行にしか現れない行を選択

Question

私はいくつかのテーブルから情報を取り出そうとしていますが、人が複数のエントリ、すなわち複数の情報行を持っている場合にのみ行を表示したいと考えています

これはそのままのコードです。私は様々な方法を使ってHAVING count（person）> 1を使用していますが、それを正しく得ることはできません。

すべてのご協力をよろしくお願いいたします。

SELECT DISTINCT 
      table1.person 
     , table1.id 
     , table1.type 
     , table1.active 
     , table2.stage 
     , table3.start 
     , table3.end 

FROM 
      people table1 
     , storyType table2 
     , storyContract table3 

WHERE 
     table1.type = table2.type_id 
    AND table2.stage = 1 
    AND table1.id = table3.contract_id 
    AND table3.start > '2015-01-01 00:00:00' 

現在の結果は

person   id  start    end     type active stage

Answer 1

;With cte 
as 
(
--this can be your join logic.Replace everything except rownum from join 
select 
*,row_number() over (partition by person order by (select null)) as rownum 
from 
table 
) 
select * from cte where rownum>1 

Answer 2

を望んでいます。

例：

DECLARE @Orders TABLE (Person VARCHAR(32), Ord VARCHAR(128)); 

INSERT INTO @Orders (Person, Ord) VALUES ('Brett', 'Shirt'), ('Brett', 'Pants'), ('Mary', 'Dress') 

--Everything as is 
Select * 
From @Orders 


-- getting ordersOver2 
; With ordersOver2 as 
    (
    Select 
     Person 
    , COUNT(Ord) AS cnt 
    FROM @Orders 
    GROUP BY Person 
    HAVING COUNT(Ord) > 1 
    ) 
-- relating this to main set 
Select a.* 
From @Orders a 
    JOIN ordersOver2 b ON b.Person = a.Person 

Answer 3

あなたはTheGameiswarのソリューションを適応させることができます。 はperson行が繰り返されたテーブルを検索し、おそらく、それらをフィルタリング

;With cte 
as 
(
--this can be your join logic.Replace everything except count(*) from join 
select 
*,count(*) over (partition by person) as PersonCount 
from 
table 
) 
select * from cte where PersonCount>1 

Answer 4

ROW_NUMBERの代わりに解析関数の数を使用しますstoryContractテーブルはpersonを繰り返し、

SELECT /* DISTINCT <- no need for distinct probably */ 
      table1.person 
     , table1.id 
     , table1.type 
     , table1.active 
     , table2.stage 
     , table3.start 
     , table3.end 

FROM 
      people table1 
     , storyType table2 
     , storyContract table3 

WHERE 
     table1.type = table2.type_id 
    AND table2.stage = 1 
    AND table1.id = table3.contract_id 
    AND table3.start > '2015-01-01 00:00:00' 
    -- ----- additional filter ---------------------- 
    AND Exists(
      SELECT 1 
      FROM storyContract as c 
      WHERE c.contract_id = table1.id 
      HAVING COUNT(1) > 1 
    ) 
    -- ----------------------------------------------
