. NET Transaktionssperre Problem

Question

Ich habe ein seltsames Problem mit Transaktionssperre und ich kann nicht darauf hinweisen, wo das Problem kommt.

Unser Kunde berichtete, dass sie eine Seite des Systems nicht verwenden können, und es gab Zeitüberschreitung. Diese Seite führt eine gespeicherte Prozedur aus, die CTE, aber keine Transaktionen enthält. Siehe meine gespeicherten Prozedur unter:

ALTER PROCEDURE [dbo].[X_WMS_GET_SALESORDERS_CUSTOM] 
@SelectedLocations VARCHAR(100) = null, 
@FromDueDate DateTime= NULL, 
@ToDueDate DateTime = NULL, 
@SearchTerm VARCHAR(200) = NULL, 

-- Dynamic filters 
-- * Display name will be the parameter name without the @FILTER_ and underscores(_) are replaced by white space(). 
-- * BIT datatype is the equivalent of boolean or char(1) 'Y' or 'N'. This will display a Yes/No dropdown selection on UI. 
@FILTER_Order_Date_from DATETIME = NULL, 
@FILTER_Order_Date_to DATETIME = NULL, 
@FILTER_Account VARCHAR(200) = NULL, 
@FILTER_Locked BIT = NULL, 
@FILTER_Stocks_Ready BIT = NULL, 
@FILTER_Zones VARCHAR(MAX) = NULL, 

-- Pagination parameters 
@START INT = 0, 
@LENGTH INT = 0, -- // 0 = ALL 
@SEARCH VARCHAR(250) = '', 
@SORTCOLUMN VARCHAR(250) = 'Order No', 
@SORTDIRECTION INT = 0 -- // ASC = 0, DESC <> 0

Während der Seite noch nach unten ist Ich habe versucht, die gespeicherte Prozedur manuell auf SQL Management ausgeführt und führt innerhalb von 1 oder 2 Sekunden ohne Probleme. Ich verwende ASP.Net MVC, um das Ergebnis dieser gespeicherten Prozedur anzuzeigen.

Ich habe den Server neu gestartet, aber das Problem besteht immer noch. Der einzige Weg, den ich in der Lage war, es zu lösen, bestand darin, jede Zeile der gespeicherten Prozedur zu ändern, sie auszuführen und die Änderungen rückgängig zu machen und erneut auszuführen, dann löst es das Problem auf magische Weise auf.

Hat jemand dies festgestellt? Jede Hilfe wäre sehr dankbar, da ich war fragen morgen zu berichten, was gerade passiert ist, und ich brauche etwas auf unserer Konferenz zu sagen :(

TIA

1. An manchen Orten haben Sie verwendet „select *“, nur die gewünschte Spalte auswählen. 2.Monitor Ihre Abfrage von SQL Profiler oder Aktivitätsmonitor, wenn es von Seite getroffen wird. 3. wenn Sie Deadlock konfrontiert sind, überwachen sie von SQL Profiler genauen Grund zu kennen.
