DBCC TRACEON (9134, -1)
When trace flag 9134 is turned on and a row is deleted or modified between the time SQL Server reads the location of the row and the time it fetches the row through a bookmark lookup, the query will not abort or return Error 601. Instead, SQL Server ignores the row that cannot be located and it continues to scan for additional rows that meet the query criteria. Therefore, the query execution continues; however, the results that SQL Server returns may not include rows that were deleted or moved during the query execution.
Note The information in this article and the trace flag only apply to a query that is being run with the Transaction Isolation Level set to READ UNCOMMITTED. The information does not apply to a query that is run with the NOLOCK optimizer hint. In that case, the behavior remains unchanged from what is described in the "Symptoms" section.
Also, the trace flag does not affect the fact that other errors and data inconsistencies can occur when reading uncommitted data. For more information about the isolation levels supported by SQL Server and the effect of using each isolation level, see the "Locking" topic in SQL Server Books Online.
Microsoft does not recommend the use of this trace flag unless all the following apply:
- The application in use requires a READ UNCOMMITTED isolation level.
- The application in use is experiencing a large number of 601 errors.
- You understand that when you use the trace flag, the rows that were deleted or moved during the query execution are ignored.
