在Sql Server中刪除Stored Proc Deadlock

我在SQL Server 2005中遇到以下死鎖，並且存在特定的刪除存儲過程，我無法弄清楚我需要做些什麼來糾正它。在Sql Server中刪除Stored Proc Deadlock

「tSecuritiesRecords」的聚簇索引鍵是什麼？ – 2010-05-28 17:42:20

你缺少一個指標：

create index idxSecuritiesAccountFiling 
    on tSecuritiesRecords (AccountID, FillingID);

會費缺乏指數的DELETE操作，都必須做的範圍掃描和獲取序列化的鎖，以穩定刪除操作。當他們轉身嘗試將S鎖轉換爲X鎖時，它們會發生死鎖。使用索引後，獲取的範圍鎖不會重疊。

我仍然得到死鎖創建以下索引後： CREATE NONCLUSTERED INDEX [IX_AccountID_FilingID] ON [DBO] [tSecuritiesRecords] （ \t [帳戶ID] ASC， \t [FilingID] ASC ）WITH（PAD_INDEX = OFF。，[STATIME] GO – Chris 2010-06-01 15:48:07

你試圖從不同的連接中刪除重疊範圍嗎？相同的@AccountID和/或相同的@FillingID？ – 2010-06-01 19:01:01

順便說一句，你可以發佈新的死鎖信息？如果使用新的索引，圖表*必須*不同，我想看看如何。 – 2010-06-01 20:30:14
