मैं एक "आकस्मिक" डीबीए हूं, इस समस्या से अपेक्षाकृत अनुभवहीन और चकित हूं।
MS SQL सर्वर 2012 चला रहा है। समस्या इस अद्यतन कथन के साथ है:
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'
जो tAccts तालिका में केवल उन पंक्तियों को अद्यतन करना चाहिए जो vReclaimable दृश्य द्वारा वापस आ जाती हैं।
VReclaimable दृश्य tAccts तालिका पर आधारित है और tAccts में पंक्तियों का एक सबसेट लौटाता है।
जब मैं इसे चलाता हूं, तो यह एक अद्वितीय कुंजी त्रुटि के साथ विफल हो जाता है:
(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.
उचित रूप से, tAccts तालिका में एक विशिष्ट कुंजी बाधा होती है:
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)
लेकिन यहाँ अजीब बात है। अगर मैं इन दो प्रश्नों को चलाता हूं:
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
पहली दो पंक्तियाँ लौटाती हैं (अपेक्षानुसार):
(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
और दूसरा रिटर्न 0 पंक्तियाँ (जैसा कि अपेक्षित है)।
यदि "VReclaimable WHERE OHR_EmpStatus <> 'A' से 0 पंक्तियाँ मिलती हैं, तो UPDATE उस पंक्ति को अद्यतन करने का प्रयास क्यों कर रहा है जहाँ DNIS = 68497 है?
(मुझे आशा है कि मैंने इसे पर्याप्त रूप से वर्णित किया है। मुझे लग रहा है कि मुझे कुछ स्पष्ट याद आ रहा है)
