Bug #: 50002349 (SQL Hotfix)

SYMPTOMS

Consider the following scenario. You create a merge publication in Microsoft SQL Server 2005. You set the @use_partition_groups parameter for the merge publication to false. You create subset filters and join filters for the tables in the publication. You make some updates on the tables from a subscriber, and then you synchronize the replication. In this scenario, some data on the publication may be lost.

For example, you have four tables in the publication that are named A, B, C, and D. You follow these steps to create subset filters and join filters for the tables:
  1. You create a subset filter on table A.
  2. You create a join filter on table B with table A. Table A is the parent table, and table B is the child table.
  3. You create a join filter on table C with table B. Table B is the parent table, and table C is the child table.
  4. You create a join filter on table D with table B. Table B is the parent table, and table D is the child table.
On a subscriber, you make some updates to table B so that some rows no longer match the join filters. These rows are also known as out-of-partition rows. Then, you make some updates on these out-of-partition rows on table C or on table D from the subscriber. In this example, when you synchronize the updates from the subscriber to the publisher two times, you may find these rows are incorrectly deleted from table C and table D on the publication.

CAUSE

This issue occurs because of a code change in the sp_Msdelsubrowsbatch stored procedure in SQL Server 2005. When you synchronize the data, the out-of-partition rows for child tables are deleted by using the sp_Msdelsubrowsbatch stored procedure at the subscriber. However, the out-of-partition rows in table B are deleted as a system delete operation. The out-of-partition rows in table C and table D are deleted as a user delete operation. When you synchronize the data again, the rows that were deleted as a user delete operation are deleted on the publisher.

RESOLUTION

The fix for this issue was first released in Cumulative Update 6. For more information about how to obtain this cumulative update package for SQL Server 2005 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:
