SQL Server開啟READ_COMMITTED_SNAPSHOT

設置數據庫為SINGLE_USER模式,減少鎖定時間

ALTER DATABASE dbname SET SINGLE_USER WITH ROLLBACK IMMEDIATE

ALTER DATABASE dbname SET ALLOW_SNAPSHOT_ISOLATION ON

ALTER DATABASE dbname SET READ_COMMITTED_SNAPSHOT ON

ALTER DATABASE dbname SET MULTI_USER

開啟之后一天了沒有看到死鎖的記錄，還是有點作用的！
