我想通過查看t-sql跟蹤來理清死鎖,但我正在努力理解這些信息。我這裏有信息的彙總,然後在帖子的末尾全死鎖跟蹤:如何解釋一個t-sql死鎖跟蹤
第一把鎖是一種叫做dbo.RetailVoucher
第二鎖是一種叫做ooc.PlannedUniversalVoucher
第一個存儲過程讀取下表:
dbo.RetailVoucher,ooc.PlannedOrderItem和ooc.PlannedOrder。
第2存儲過程讀取以下表格:
ooc.PlannedBatch & ooc.PlannedUniversalVoucher
現在,在等待對方的程序,我以爲他們會都必須讀取相同的表在某一點。我顯然不明白如何解釋蹤跡。我是否需要在其他程序中追蹤dbo.RetailerVoucher和ooc.PlannedUniversalVoucher上的鎖的來源?
謝謝。
下面是完整的跟蹤:
