其中參數集中的ID和沒有其他地方（1行數據）

Question

使用Sql服務器： 我想知道這個ID（MrHCClaim_id）在這個標準集中的位置，但不屬於任何其他標準。基本上找到只有一行數據的ID。

我曾嘗試：

select MrHcClaim_id, HospCd, PyrNm, payor, PatNo, SvDate, 
    sum(case when HcPcS in ('99211', '99212', '99213', '99214', '99215') 
       and SvMod like '%25%' 
      then cast(units as decimal) else 0 end) as "E&M25s", 
    sum(cast (units as decimal)) as "units" 

from MrHcClaim as a 
    left join MrHcClaimDtl as c 
    on a.MrHcClaim_id = c.MrHcClaimDtl_id 

where SvDate between '11/01/2016' 
       and '11/30/2016' 
    and payor = '1' 
    and (billstatus = 't' or billstatus = 'p') 
    and hospcd <> 'saltzer' 

group by MrHcClaim_id, HospCd, PyrNm, payor, PatNo, SvDate 
having sum(case when HcPcS in ('99211', '99212', '99213', '99214', '99215') 
        and svmod like '%25%' 
       then cast(units as decimal) else 0 end) > 0 
     and sum(cast(units as decimal)) = sum(case when hcpcs in 
        ('99211', '99212', '99213', '99214', '99215') 
     and svmod like '%25%' then units else 0 end)

我相信你想另一個條件添加到您的HAVING子句：

select MrHcClaim_id, HospCd, PyrNm, payor, PatNo, SvDate, 
    sum(case when HcPcS in ('99211', '99212', '99213', '99214', '99215') 
       and SvMod like '%25%' 
      then cast(units as decimal) else 0 end) as "E&M25s", 
    sum(cast (units as decimal)) as "units" 

from MrHcClaim as a 
    left join MrHcClaimDtl as c 
    on a.MrHcClaim_id = c.MrHcClaimDtl_id 

where SvDate between '11/01/2016' 
       and '11/30/2016' 
    and payor = '1' 
    and (billstatus = 't' or billstatus = 'p') 
    and hospcd <> 'saltzer' 

group by MrHcClaim_id, HospCd, PyrNm, payor, PatNo, SvDate 
having sum(case when HcPcS in ('99211', '99212', '99213', '99214', '99215') 
        and svmod like '%25%' 
       then cast(units as decimal) else 0 end) > 0 
     and sum(cast(units as decimal)) = sum(case when hcpcs in 
        ('99211', '99212', '99213', '99214', '99215') 
     and svmod like '%25%' then units else 0 end) 
     and COUNT(DISTINCT MrHcClaim_id) = 1 

這會給你只是結果，其中只有與一個記錄MrHcClaim_id值。
