ssrsグラフのsqlクエリ式に存在しない値を処理する

Question

ssrs折れ線グラフで次のクエリを使用しています。各注文日に基づいて毎月記録される注文の数をカウントします。

私の問題は、月に何も注文がない場合、ゼロまたはヌルというよりも、その月の行をまとめて削除することです。私はゼロとしてそれを数えることを好むだろうが、nullも大丈夫だろう。

基本的には、情報が含まれているかどうかにかかわらず、常に12行が必要です。

どうすればこの問題を解決できますか？私は何か使える表現がありますか？あるいは、私は完全に明白な何かを逃しています

SELECT 
MONTH(Ord.OrdDate) AS 'MONTH', 
COUNT(CASE WHEN @Worker_ID1 IS NULL OR @Worker_ID1 = Worker.ID THEN 1 END) AS 'Worker1', 
COUNT(CASE WHEN @Worker_ID2 IS NULL OR @Worker_ID2 = Worker.ID THEN 1 END) AS 'Worker2', 
COUNT(CASE WHEN @Worker_ID3 IS NULL OR @Worker_ID3 = Worker.ID THEN 1 END) AS 'Worker3', 
COUNT(CASE WHEN @Worker_ID4 IS NULL OR @Worker_ID4 = Worker.ID THEN 1 END) AS 'Worker4', 
COUNT(CASE WHEN @Worker_ID5 IS NULL OR @Worker_ID5 = Worker.ID THEN 1 END) AS 'Worker5' 

FROM Ord 
JOIN Prod ON Ord.Prod_ID = Prod.ID 
JOIN ProdType ON Prod.ProdType_ID = ProdType.ID 
JOIN Grouping ON Ord.Grouping_ID = Grouping.ID 
JOIN Worker ON Grouping.Worker_ID = Worker.ID 

WHERE @Year = YEAR(Ord.OrdDate) 
AND (@ProdType_ID IS NULL OR @ProdType_ID = ProdType.ID) 

GROUP BY MONTH(Ord.OrdDate) 

Answer 1

それはカウント集計にWHERE句やフィルタリングを除去することにより、作業手に入れました。

SELECT 
MONTH(Ord.OrdDate) AS 'MONTH', 
COUNT(CASE WHEN @Year = YEAR(Ord.OrdDate) AND Worker.ID = @Worker_ID1 AND @ProdType_ID = ProdType.ID THEN 1 END) AS 'Worker1', 
COUNT(CASE WHEN @Year = YEAR(Ord.OrdDate) AND Worker.ID = @Worker_ID2 AND @ProdType_ID = ProdType.ID THEN 1 END) AS 'Worker2', 
COUNT(CASE WHEN @Year = YEAR(Ord.OrdDate) AND Worker.ID = @Worker_ID3 AND @ProdType_ID = ProdType.ID THEN 1 END) AS 'Worker3', 
COUNT(CASE WHEN @Year = YEAR(Ord.OrdDate) AND Worker.ID = @Worker_ID4 AND @ProdType_ID = ProdType.ID THEN 1 END) AS 'Worker4', 
COUNT(CASE WHEN @Year = YEAR(Ord.OrdDate) AND Worker.ID = @Worker_ID5 AND @ProdType_ID = ProdType.ID THEN 1 END) AS 'Worker5' 

FROM Ord 
JOIN Grouping ON Ord.Grouping_ID = Grouping.ID 
JOIN Worker ON Grouping.Worker_ID = Worker.ID 
JOIN Prod ON Ord.Prod_ID = Prod.ID 
JOIN ProdType ON Prod.ProdType_ID = ProdType.ID 

GROUP BY MONTH(Ord.OrdDate) 

Answer 2

この動作は、SQL構文 "内部結合"によって明確に定義されています。 使用は、結合条件は、以下のように満たさない場合

SELECT 
MONTH(Ord.OrdDate) AS 'MONTH', 
COUNT(CASE WHEN @Worker_ID1 IS NULL OR @Worker_ID1 = Worker.ID THEN 1 END) AS 'Worker1', 
COUNT(CASE WHEN @Worker_ID2 IS NULL OR @Worker_ID2 = Worker.ID THEN 1 END) AS 'Worker2', 
COUNT(CASE WHEN @Worker_ID3 IS NULL OR @Worker_ID3 = Worker.ID THEN 1 END) AS 'Worker3', 
COUNT(CASE WHEN @Worker_ID4 IS NULL OR @Worker_ID4 = Worker.ID THEN 1 END) AS 'Worker4', 
COUNT(CASE WHEN @Worker_ID5 IS NULL OR @Worker_ID5 = Worker.ID THEN 1 END) AS 'Worker5' 

FROM Prod 
LEFT JOIN ORD ON Ord.Prod_ID = Prod.ID 
JOIN ProdType ON Prod.ProdType_ID = ProdType.ID 
JOIN Grouping ON Ord.Grouping_ID = Groupord.ID 
JOIN Worker ON Grouping.Worker_ID = Worker.ID 

WHERE ((Ord.OrdDate is not null and @Year = YEAR(Ord.OrdDate)) or ORD.prod_id is null) 
AND (@ProdType_ID IS NULL OR @ProdType_ID = ProdType.ID) 

GROUP BY MONTH(Ord.OrdDate) 

（試験せず）NULL値を取得する（これによっては正しい側であり、右結合）に参加注左 - 私は、where句の条件をチェックするために、追加の添加しましたSQLを結合し、この

あなたが含むテーブルを必要とすることができます（またはストアドプロシージャまたはおそらく共通のテーブル式を使用することができます）。

SELECT Months.Month, COUNT(Orders.OrderID) 
FROM 
Months 
LEFT OUTER JOIN 
Orders 
ON 
MONTH(Orders.OrderDate) = Months.Month 

は、あなたが得たことを確認します：上述の答えとして

Month, Count 
1, 1 
2, 1 
3, 2 
4, NULL 
etc 

Answer 4

を、あなたは、外部結合とカレンダーのテーブルのいくつかの種類が必要になります。これはテストされていないですが、私はあなたのために働くだろうと思う：

with dateCTE as 
(
    select cast('2012-01-01' as datetime) dateValue -- start date 
    union all 
    select DateAdd(mm, 1, dateValue) 
    from dateCTE 
    where dateValue < '2012-12-30' -- end date 
) 
SELECT 
MONTH(dateCTE.dateValue) AS 'MONTH', 
COUNT(CASE WHEN @Worker_ID1 IS NULL OR @Worker_ID1 = Worker.ID THEN 1 END) AS 'Worker1', 
COUNT(CASE WHEN @Worker_ID2 IS NULL OR @Worker_ID2 = Worker.ID THEN 1 END) AS 'Worker2', 
COUNT(CASE WHEN @Worker_ID3 IS NULL OR @Worker_ID3 = Worker.ID THEN 1 END) AS 'Worker3', 
COUNT(CASE WHEN @Worker_ID4 IS NULL OR @Worker_ID4 = Worker.ID THEN 1 END) AS 'Worker4', 
COUNT(CASE WHEN @Worker_ID5 IS NULL OR @Worker_ID5 = Worker.ID THEN 1 END) AS 'Worker5' 

FROM dateCTE 
LEFT JOIN Ord on MONTH(dateCTE.datevalue) = MONTH(Ord.OrdDate) 
JOIN Prod ON Ord.Prod_ID = Prod.ID 
JOIN ProdType ON Prod.ProdType_ID = ProdType.ID 
JOIN Groupord ON Ord.Groupord_ID = Groupord.ID 
JOIN Worker ON Groupord.Worker_ID = Worker.ID 

WHERE (@Year = YEAR(Ord.OrdDate) or ORD.prod_id is null) 
AND (@DrugType_ID IS NULL OR @ProdType_ID = ProdType.ID) 

GROUP BY MONTH(dateCTE.dateValue) 
OPTION (MAXRECURSION 0)

;WITH m(m) AS (SELECT TOP 12 ROW_NUMBER() OVER (ORDER BY [object_id]) FROM sys.objects) 
SELECT [MONTH] = m.m, 
    Worker1 = COUNT(CASE WHEN COALESCE(@Worker_ID1, w.ID) = w.ID THEN 1 END), 
    Worker2 = COUNT(CASE WHEN COALESCE(@Worker_ID2, w.ID) = w.ID THEN 1 END), 
    Worker3 = COUNT(CASE WHEN COALESCE(@Worker_ID3, w.ID) = w.ID THEN 1 END), 
    Worker4 = COUNT(CASE WHEN COALESCE(@Worker_ID4, w.ID) = w.ID THEN 1 END), 
    Worker5 = COUNT(CASE WHEN COALESCE(@Worker_ID5, w.ID) = w.ID THEN 1 END) 
FROM m 
LEFT OUTER JOIN dbo.Ord AS o 
ON o.OrdDate >= DATEADD(MONTH, m.m-1, RTRIM(@Year)+'0101') 
AND o.OrdDate < DATEADD(MONTH, m.m, RTRIM(@Year+'0101') 
INNER JOIN dbo.Prod  AS p ON o.Prod_ID  = p.ID 
INNER JOIN dbo.ProdType AS pt ON p.ProdType_ID = pt.ID 
INNER JOIN dbo.Grouping AS g ON o.Grouping_ID = g.ID 
INNER JOIN dbo.Worker AS w ON g.Worker_ID = w.ID 
WHERE (@DrugType_ID IS NULL OR pt.ID = @ProdType_ID) 
GROUP BY m.m 
ORDER BY m.m;
