我正在用SQL Report Services構建一些報告。我有此查詢：查詢中的SSRS參數代碼衰減性能？
select
FromPhone.PhoneUri as FROM_PHONE,
Agente.UserUri as AGENTE,
IVRSession.InviteTime as INVITE,
AgenteSession.ResponseTime as RESPONSE_TIME,
AgenteSession.SessionEndTime AS END_TIME,
DATEDIFF(SECOND,AgenteSession.ResponseTime, AgenteSession.SessionEndTime) as DURATA,
DATEDIFF(SECOND,IVRSession.InviteTime, AgenteSession.ResponseTime) as ATTESA,
AgenteSession.ResponseCode as RESPONSE_CODE
from
SessionDetails as IVRSession
join VoipDetails on IVRSession.SessionIdTime = VoipDetails.SessionIdTime and IVRSession.SessionIdSeq = VoipDetails.SessionIdSeq
left outer join Phones as FromPhone on FromPhone.PhoneId = VoipDetails.FromNumberId
left outer join Phones as ConnectedPhone on ConnectedPhone.PhoneId = VoipDetails.ConnectedNumberId
join SessionDetails as AgenteSession on AgenteSession.ReplacesDialogIdTime = IVRSession.SessionIdTime and IVRSession.SessionIdSeq = AgenteSession.ReplacesDialogIdSeq
left outer join Users as User1 on User1.UserId = IVRSession.User1Id
left outer join Users as User2 on User2.UserId = IVRSession.User2Id
left outer join Users as Agente on Agente.UserId = AgenteSession.User1Id
left outer join ClientVersions as Client1Version on Client1Version.VersionId = IVRSession.User1ClientVerId
left outer join ClientVersions as Client2Version on Client2Version.VersionId = IVRSession.User2ClientVerId
where
(Client1Version.ClientType = 1024 or Client2Version.ClientType = 1024) and
User2.UserUri = '[email protected]' and
IVRSession.InviteTime > '15/01/2014' and IVRSession.InviteTime < '20/02/2014'
在這種形式的所有工作正常，但... 如果我在
IVRSession.InviteTime > '15/01/2014' and IVRSession.InviteTime < '20/02/2014'
使用兩個SSRS參數（@DataDa和@DataA）而不是字符串結果時間更多。類似於> 1分鐘
爲什麼這種行爲？
感謝u爲答案，但我沒有一個存儲過程，只是一個普通的查詢 – Alist3r
好了，解決了，感謝ü – Alist3r
