Saya seorang "kebetulan" DBA, relatif tidak berpengalaman dan bingung dengan masalah ini.
Menjalankan MS SQL Server 2012. Masalahnya adalah dengan pernyataan UPDATE ini:
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'
Yang harus memperbarui hanya baris dalam tabel tAccts yang dikembalikan oleh tampilan vReclaimable.
Tampilan vReclaimable didasarkan pada tabel tAccts dan mengembalikan sebagian dari baris dalam tAccts.
Ketika saya menjalankannya, gagal dengan kesalahan kunci unik:
(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.
Cukup adil, tabel tAccts memang memiliki batasan kunci yang unik:
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)
Tapi ini yang aneh. Jika saya menjalankan dua pertanyaan ini:
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
Yang pertama mengembalikan dua baris (seperti yang diharapkan):
(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
dan yang kedua mengembalikan 0 baris (seperti yang diharapkan).
Jika “FROM vReclaimable WHERE OHR_EmpStatus <> 'A'” mengembalikan 0 baris, mengapa UPDATE mencoba memperbarui baris di mana DNIS = 68497?
(Saya harap saya telah menggambarkan ini dengan memadai. Saya merasa saya kehilangan sesuatu yang jelas)
