SSRS上字段分组=多值参数

Question

我有一个SSRS报告其中的参数中的一个是多选。我需要一个行组与集聚行有求和仅基于什么用户从下拉菜单中选择某编号的汇总行。例如....如果下拉包含A = 4，B = 7，C = 1，d = 3，让我们说，用户选择A和C只。含A和C（不分离出来成团，刚刚返回行）和总的分组只能说明行应= 5

您需要将绑定参数中是可以用“IN”计算表达式子句的多值参数。现在使用SSRS处理参数的方式不同于SQL，因此我认为您可以少用一些代码。这里是直接用SQL自动提取和运行的例子。

declare @People Table (personID int identity, person varchar(8)); 

insert into @People values ('Brett'),('Sean'),('Chad'),('Michael'),('Ray'),('Erik'),('Queyn'); 

declare @Orders table (OrderID int identity, PersonID int, Description varchar(32), Amount int); 

insert into @Orders values (1, 'Shirt', 20),(1, 'Shoes', 50),(2, 'Shirt', 22),(2, 'Shoes', 52),(3, 'Shirt', 20),(3, 'Shoes', 50),(3, 'Hat', 20),(4, 'Shirt', 20),(5, 'Shirt', 20),(5, 'Pants', 30), 
(6, 'Shirt', 20),(6, 'RunningShoes', 70),(7, 'Shirt', 22),(7, 'Shoes', 40),(7, 'Coat', 80) 


declare @Ords table 
    (
     value varchar(32) 
    ) 

--PLAY with values to see agregation works with different MULTIPLE CHOICES 
-- in reality @Ords would be your parameter and the rest of the stuff if just 
-- faking a dataset. 
insert into @Ords VALUES ('Shirt'); 
--insert into @Ords VALUES ('Shirt'),('Shoes'); 
--insert into @Ords VALUES ('Shirt'),('Shoes'),('Hat'); 

-- simple way when you can expose dataset to join to. 
Select 
    p.personID 
, p.person 
, sum(case when v.value is not null then 1 end) 
, sum(case when v.value is not null then Amount end) 
from @People p 
    left join @Orders o on o.PersonID = p.personID 
    left join @Ords v on o.Description = v.value  
group by p.personID, p.person 
order by p.personID 
; 

-- With SSRS you probably cannot JOIN directly to your parameter(never tried it though, maybe you can) 
-- so you need to do an 'IN' expression in a CTE and then aggregate your CTE. You can shorten this 
-- in SSRS to be in (@parameterName) instead of (Select value from @ParameterName) 
With a as 
    (
    Select 
     p.person 
    , p.personID 
    , case when o.Description in (Select value from @Ords) then 1 end as Cnt 
    , case when o.Description in (Select value from @Ords) then Amount end as Amount 
    from @People p 
     left join @Orders o on o.PersonID = p.personID 
    ) 
Select 
    personID 
, person 
, count(Cnt) 
, sum(Amount) 
from a 
group by personID, person 
order by personID
