.Net交易鎖問題

Question

我有一個奇怪的問題，交易鎖定，我不能指出問題的來臨。

我們的客戶報告說他們不能使用系統的一頁，並且它超時。這個頁面執行一個涉及CTE的存儲過程，但根本沒有任何事務。請參閱下面我的存儲過程：

-- 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_Stocks_Ready BIT = NULL,

雖然網頁仍下跌我試着SQL管理手動運行存儲過程和1或2秒之內沒有問題執行。我正在使用ASP.Net MVC來顯示此存儲過程的結果。

我重新啓動服務器，但問題仍然存在。我能夠解決它的唯一方法是修改存儲過程中的任何行執行它並撤消更改並再次執行，然後它神奇地解決問題。

有沒有人遇到過這個？任何幫助，因爲我是問，明天彙報剛剛發生的事情是極大的讚賞，我需要的東西，在我們的會議:(

TIA

1. 在有些地方說，你曾用「SELECT *」，選擇所需的列只。 2.Monitor從SQL事件探查器或活動監控查詢時，它從頁面。 打3.如果您正面臨僵局，從SQL事件探查器監視它知道確切的原因。
