允许使用SSRS的多个值

Question

我想在下面的代码中使用dateadd函数时使用IN @Parameter

 declare @interval int
--set @interval
SELECT ROW_NUMBER() OVER (ORDER BY datetime) AS Row, 
       RIGHT(LEFT(E.Name,  11), 8) AS Device, P.[DateTime],
       day(p.DateTime) AS Day,
       month(p.DateTime) AS Month,  
       P.AverageValue, p.StandardDeviation
FROM [dbo].[vManagedEntity] AS E  
INNER JOIN [Perf].[vPerfDaily] AS P ON E.ManagedEntityRowId = P.ManagedEntityRowId    
INNER JOIN [dbo].[vPerformanceRuleInstance] AS I ON 
P.PerformanceRuleInstanceRowId = I.PerformanceRuleInstanceRowId  
INNER JOIN [dbo].[vPerformanceRule] AS R ON R.RuleRowId = I.RuleRowId
WHERE     right(left(e.name,6),3)  IN (@Site) 
      AND R.CounterName = 'MPLS    Utilization % (Average)' 
      AND p.DateTime >= DATEADD(MM, (@interval), GetUTCDate())

我想使用

p.DateTime >= DATEADD(MM, IN (@interval), GetUTCDate())

但它不允许它。
