TSQL Hack nécessaire pour obtenir un filtre pour les données

Question

Une interface utilisateur (avant que le rapport montre) montre un coup d'oeil vers le haut (Combo) qui a

• (ID = 0) Unités .Toutes Organisation
• (ID = 4) .HR
• (ID = 5) .DEV

Je dois:

4. Pouvoir afficher les données de (4) + (5) (0) est sélectionné.
5. Seulement (4) ou (5) si l'une des ressources humaines ou DEV est sélectionné.

Recherche code combo (le paramètre sélectionné Flux dans la requête ci-dessous.)

Select 0 AS ID,'All Org' AS Name from  DP_ORG_OrganizationUnit
where DP_ORG_OrganizationUnit.Code IN {AccessData}
Union
SELECT 
DP_ORG_OrganizationUnit.ID,
DP_ORG_OrganizationUnit.Name
FROM DP_ORG_OrganizationUnit  where DP_ORG_OrganizationUnit.Code IN ('HR','DEV')

SET CONCAT_NULL_YIELDS_NULL OFF

DECLARE @EmpID as int; 
DECLARE @OrganizationUnit as int; 
DECLARE @StartDate as datetime;
DECLARE @EndDate as datetime;

SET @EmpID = ?;
SET @StartDate = ?;
SET @EndDate = ?;
SET @OrganizationUnit = ?;

SELECT
Employee.Code,
Employee.Name1+' '+Employee.Name2+' '+Employee.Name3+' '+Employee.Name4+' '+Employee.Name5 AS FullName,
Employee.OrganizationUnit,  
ContractType.Name,
EmployeeContract.StartDate,
EmployeeContract.EndDate
FROM Employee INNER JOIN (ContractType INNER JOIN EmployeeContract 
ON ContractType.ID = EmployeeContract.ContractType) 
ON Employee.ID = EmployeeContract.Employee
WHERE (Employee.ID = @EmpID  OR  @EmpID=0)
AND
(Employee.OrganizationUnit = @OrganizationUnit  OR  @OrganizationUnit=0)
AND  NOT((EndDate <  @StartDate or StartDate > @EndDate));

De toute façon je peux réaliser des regards de celui-ci? 0 = 0 montreraient toutes les données d'autres départements trop ..

Tout le monde: -o

Answer 1

Tout d'abord, votre code combo de recherche pourrait être serré un peu:

-- the FROM clause was superfluous
SELECT 0 AS ID,'All Org' AS Name 
UNION ALL
-- the two-part identifiers were superfluous (only one table)
SELECT ID, Name
FROM DP_ORG_OrganizationUnit
WHERE Code IN ('HR','DEV')

Pour la requête de rapport, la forme la plus simple serait:

WHERE 
  ((@OrganizationUnit > 0 AND Employee.OrganizationUnit = @OrganizationUnit) OR 
   (@OrganizationUnit = 0 AND Employee.OrganizationUnit IN (4,5)))

Answer 2

chose comme cela devrait fonctionner

Where (Employee.OrganizationUnit = case when @OrganizationUnit=0 then 4 else @OrganizationUnit end OR case when @OrganizationUnit=0 then 5 else @OrganizationUnit end)

Answer 3

Essayez ceci, qui devrait utiliser les index sur votre requête ...

DECALRE @FilterValues (FilterValue   int not null primary key)

IF @Param=0
BEGIN
    INSERT INTO @FilterValues VALUES (4)
    INSERT INTO @FilterValues VALUES (5)
END
ELSE ID @PAram IS NOT NULL
BEGIN
    INSERT INTO @FilterValues VALUES (@Param)
END

SELECT
    ....
    FROM YourTable                y
        INNER JOIN @FilterValues  f ON y.Value=f.Value
    WHERE .....

Answer 4

La version de KM fonctionnera, mais cette requête n'a pas besoin d'une table temp ...

SELECT *
FROM Employee
WHERE (
         @OrganizationUnit = 0
         OR 
         (
             @OrganizationUnit <> 0
             AND
             Employee.OrganizationUnit = @OrganizationUnit
         )
      )

Answer 5

Qu'en est-

WHERE (Employee.ID = @EmpID  OR  @EmpID=0)
AND
(Employee.OrganizationUnit BETWEEN ISNULL(NULLIF(@OrganizationUnit,0),0) AND ISNULL(NULLIF(@OrganizationUnit,0),99))
AND  NOT((EndDate <  @StartDate or StartDate > @EndDate));
