Question

I have a C# application which is inserting data into SQL Server (2008) table using stored procedure. I am using multi-threading to do this. The stored procedure is being cal

You can encapsulate your query in a TRY CATCH block, and catching error numbers (related to locks)

1. 1204
2. 1205
3. 1222

Then you can automate retries, up to a certain number.. So you would do something like the following;

         DECLARE @RetryNo Int = 1
     ,@RetryMaxNo Int = 5;
   WHILE @RetryNo < @RetryMaxNo
      BEGIN
         BEGIN TRY 

         -- put your query that generates locks here....

            SELECT   @RetryNo = @RetryMaxNo;
         END TRY
         BEGIN CATCH
            IF ERROR_NUMBER() IN (1204, 1205, 1222)
               BEGIN
                  SET @RetryNo += 1;
                  -- it will wait for 10 seconds to do another attempt
                  WAITFOR DELAY '00:00:10';
               END 
            ELSE
               THROW;
         END CATCH
      END 

You can also use table hints such as UPDLOCK.
