sql server中怎樣查詢引起死鎖的sql語(yǔ)句？

當(dāng)死鎖發(fā)生后，通過(guò)服務(wù)端的Trace就可以將死鎖信息傳到日志。在SQL Server 2000時(shí)代，只能通過(guò)Trace flag 1204來(lái)開(kāi)啟，由于Trace flag 1204并不能提供XML死鎖圖，在SQL Server 2005以及之后的版本被Trace flag 1222所取代。 為了在服務(wù)端針對(duì)所有的Session開(kāi)啟Trace flag 1222。可以通過(guò)如代碼所示。DBCC TRACEON(1222，-1)另一種方法是開(kāi)啟Profiler來(lái)捕捉，Profiler捕捉到的圖示死鎖信息內(nèi)容就更直觀了，
