Update with rowlock in sql

I get the feeling that I may have written the above myself. In a response to a question of yours. I would really recommend that you go back and review your old threads rather than posting the same question again.

Sir ErlandSommarskog please guide me further. For question 4 I also get the question that I have answered you before on this point and more than once. I urge you to go back and review your previous threads. So you need to ensure that you don't get a query plan with page locks instead of row locks. Delete duplicated lines based on 2 primary key.

You can see the full explanation in the Table Hints page in the documentation. Best is to let SQL Server to determine the granularity. SQL Server can take locks on different levels: row, page, partition and table. Best is to let SQL Server decided what is best. But you can use hints to mandate the lock to be taken on row, page or table-level.

Don't think there is a hint for partition level locks. What can happen if you abuse the ROWLOCK hint and use it query will millions of rows will be read is that you can consume a lot of memory for all those rowlocks. Delete duplicated lines based on 2 primary key. Its no longer in the queue but once was - was it processed or not?

LowlyDBA Nothing happened to the row, it is still in the queue with the same status ready for processing. There is no order by in the first query because it does not matter which record is processed next.

The readpast hint exists specifically to make sure that multiple queue processors will not grab the same row and will not be blocked by each other, and we currently have only one queue processor. The same ID should be visible to any code called by the processor because they are within the same transaction. Can you post the create statement for the queue table?

MisterMagoo Serializable defeats the purpose of readpast. On top of that, updlock is not released prematurely, only shared locks do. I think you need only updlock, readpast. Can you explain why use three hints. I think you should check compatibility Level of Where is rollback? If there is error in 2nd proc then can it RollBack. Or if 2nd proc do ot process then should it rollback.
