![]() The best I could come up with via internet research is the notion that I should set nonclustered indexes on the primary table, however the stored proc is not inserting anything into child tables, just doing a very basic update to the primary table. Retry the transaction or change the isolation level for the update/delete statement. ![]() You cannot use snapshot isolation to access table 'dbo.yyyyyy' directly or indirectly in database 'xxxxxx' to update, delete, or insert the row that has been modified or deleted by another transaction. In SQL Server 20R2, the query to retrieve the deadlock graph from the systemhealth session was (excluding the work around that was included in the original article since the xmldeadlockreport was fixed in a later Cumulative Update and the latest Service Pack for SQL Server 20 R2). > : Snapshot isolation transaction aborted due to update conflict. Using (var tscope = new TransactionScope(TransactionScopeOption.Required, new TransactionOptions ))Īn error occurred while updating the entries. Visual studio C# code around the stored proc call reads: I Updated the database to allow committed snapshot and snapshot isolation:ĪLTER DATABASE xxxxx SET READ_COMMITTED_SNAPSHOT ON ĪLTER DATABASE xxxxx SET ALLOW_SNAPSHOT_ISOLATION ON Deadlock prevention mechanism proposes two schemes: Wait-Die Scheme: In this scheme, If a transaction requests a resource that is locked by another transaction, then the DBMS simply checks the timestamp of both transactions and allows the older transaction to wait until the resource is available for execution. Here is the backgroundĭuring processing a stored proc updates a specific record in a table, thus the deadlock occurs between the two processes I'm having a concurrent deadlock issue, two batch jobs running simultaneously. ![]()
