Ben "kazara" bir DBA, nispeten deneyimsiz ve bu sorun şaşkın.
MS SQL Server 2012 çalıştırılıyor. Sorun bu UPDATE deyimi ile:
UPDATE dbo.tAccts SET
Ticket = 'ARP.ExGE'
, Method = 'smtp'
, AcctOwner = 'r00417819'
, DisplayName = '~AppLight HBSFax-Inactive'
, Destination = 'r00417819@mail.ad.ge.com'
, UpdatedBy = SYSTEM_USER
, UpdatedOn = CAST(GetDate() AS DATE)
FROM dbo.vReclaimable
WHERE OHR_EmpStatus <> 'A'
Hangi gerektiğini güncellemek sadece vReclaimable görünümü tarafından döndürülen tAccts tablodaki satırları.
VReclaimable görünümü, tAccts tablosunu temel alır ve tAccts'deki satırların bir alt kümesini döndürür.
Çalıştırdığımda, benzersiz bir anahtar hatasıyla başarısız oluyor:
(0 row(s) affected)
Msg 2627, Level 14, State 1, Line 67
Violation of UNIQUE KEY constraint 'UQ__tAccounts_DNIS.Method.Destination.Phones'. Cannot insert duplicate key in object 'dbo.tAccts'. The duplicate key value is (68497, smtp, r00417819@mail.ad.ge.com, 800-905-8793, none).
The statement has been terminated.
Oldukça adil, tAccts tablosunun benzersiz bir anahtar kısıtlaması var:
CONSTRAINT [UQ__tAccounts_DNIS.Method.Destination.Phones] UNIQUE NONCLUSTERED
(
[DNIS] ASC,[Method] ASC,[Destination] ASC,[Phone_TF] ASC,[Phone_Local] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
Ama işte garip olan şey. Bu iki sorguyu çalıştırırsam:
select 'tAccts table', dnis, method, destination, phone_tf, phone_local from tAccts where dnis=68497
select 'vReclaimable view', dnis, method, destination, phone_tf, phone_local, daysidle from vReclaimable where dnis=68497
Birincisi iki satır döndürür (beklendiği gibi):
(No column name) dnis method destination phone_tf phone_local
tAccts table 68497 ftp ftp://faxuser@ap1plm02cige/appliances 800-905-8793 none
tAccts table 68497 unc \\\\for4as01applge\\cfs_portfolio\\cfs_faxdocs 800-905-8793 none
ve ikincisi 0 satır döndürür (beklendiği gibi).
“FROM vReclaimable WHERE OHR_EmpStatus <> 'A'” 0 satır döndürürse, UPDATE neden DNIS = 68497 olduğu satırı güncellemeye çalışıyor?
(Umarım bunu yeterince açıklamışımdır. Açık bir şeyi özlediğimi hissediyorum)
