Question

UI（在报告显示之前）显示具有

的查找（组合）

（ID = 0）。所有组织单位
（ID = 4）.HR
（ID = 5）.DEV

我需要：

能够显示（4）+（5）的数据选择（0）。
如果选择了HR或DEV，则仅（4）或（5）。

查找组合代码（已选择在以下查询中提供参数。）

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')

报告数据行查询

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));

任何方式我都可以从它的外观中实现它？ 0 = 0将显示来自其他的所有数据部门也是..

任何人：-o？

Answer 1

首先，您的查找组合代码可能会收紧一点：

-- 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')

对于报告查询，最简单的形式是：

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

Answer 2

这样的事情应该起作用

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

Answer 3

怎么样

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

试试这个，应该在查询中使用索引...

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

KM的版本可以使用，但此查询不需要临时表...

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