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

Je dois:

4. Pouvoir afficher les données de (4) + (5) si (0) est sélectionné.
5. Seulement (4) OU (5) si HR 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 afficherait également toutes les données des autres départements ..

Personne: -o?

Answer 1

Tout d'abord, votre recherche code combo pourrait être resserré 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

quelque 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

Que diriez-vous

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)); 

Answer 4

Essayez ce 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 5

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

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