Sometimes, you might not be able to stop and re-start SQL Server. In that case, you can use Query Analyzer to run the following command to enable the deadlock trace flags. Note This way you can gather information about the deadlocks immediately. The "-1" indicates all SPIDs. dbcc trace...
Re: How to resolve deadlock caused during concurrent inserts into one table Posted by:DBA Lead Date: September 23, 2010 10:27AM I don't understand why using advisory locks will slow down the processing significantly. Whereas, you are suggesting retrying on deadlocks. Advisory locks is a ...
In this article, we explained deadlocks in SQL Server and then analyze a true story that was experienced by a development team. The significant point to generate a solution is properly understanding and interpreting the deadlock report and graph. Otherwise, it will be very difficult to find the...

<soapbox>it may be an aside to this deadlock issue, and I cannot see the code, but do you really need to use dynamic SQL here? If you decide to make changes to the system to reduce deadlocks try to remove it. If you want help with that effort post the proc code and we'll help...
but it may transpire that two updates of the same program occur at around the same time (the program updating itself, and the master orchestrator update on behalf of the child program). However the number of deadlocks (up to 10 in a few minutes) compared with the likelyhood that any two...
other tables. In that way, all transactions happen in a serial fashion. Note that theInnoDBinstant deadlock detection algorithm also works in this case, because the serializing lock is a row-level lock. With MySQL table-level locks, the timeout method must be used to resolve deadlocks. ...

One can resolve deadlocks by using TRY CATCH blocks. If the code inside a TRY statement fails, the CATCH automatically catches the control of the flow letting the transaction rollback and resume execution. What is a deadlock and what is a live lock? How will you go about resolving deadlocks...
I am aware of the approach you suggested but wouldn't it be better if we simply avoid the deadlock by using some kind of locking mechanism to completely avoid the problem? Or, else keep trying to insert the record and get deadlocks because the other transaction is still active. ...
