SSRS 中的兩個多值參數

Question

我的 SQL 中有兩個多值參數：其中 (PayToTIN IN (@PayToTIN) 或 PCP_ProvId IN (@PCP_ProvId)。我試圖在其中一個或參數中放入多個值但是當我在任一參數中放入一個值時， SSRS 將另一個參數視為 ''。我也無法從其中一個參數中刪除 null，因為它們是多值的。是否有解決方法可以在一個參數或另一個參數中運行多個值？

    Declare @PayToTIN as varchar(max) = '562660402' --'562660402'   
Declare @PCP_ProvId as varchar(max) --= 'LASRL12550' --'LASRL12550'
declare @detailfields as varchar(max) = NULL

declare @PayToTIN_switch varchar(max) =  
    (   select max(PayToTIN)
        from LA_Temp.dbo.vMemberPCP
        where cast(PayToTIN as varchar) in (@PayToTIN)
    )

declare @PCPAssignmentID_switch varchar(max) =  
    (   select max(PCP_ProvId)
        from LA_Temp.dbo.vMemberPCP
        where cast(PCP_ProvId as varchar) in (@PCP_ProvId)
    )

declare @include_PayToTIN bit = case when 'Pay To Tin' in (@detailfields) then 1 else 0 end 
declare @include_PCP_ProvId bit = case when 'PCP ProvID' in (@detailfields) then 1 else 0 end

        or (    PCP_ProvId IN (@PCP_ProvId)
                or '' = @PCPAssignmentID_switch
                    )

Answer 1

where (case when PayToTIN = '' then null else PayToTIN end in (@PayToTIN)) 
OR (case when PCP_ProvId = '' then null else PCP_ProvId end in (@PCP_ProvId))
