I am merge replicating between two SQL 2008 R2 servers.   These are hardly touched, yet when I did a synchronisation, I had loads of updates.

How can I find out which rows were changed?

Thanks,

  Colin

Merge replication tracks the dml changes by using Insert, update and delete triggers, these changes are tracked in tables MSMerge_tombstone (For Deletes) MSMerge_Contents (For Update and Inserte) and MSMerge_GenHistory  (Group of changes). Replicated tables has rowguid column, so when a row changes its rowguid is tracked in corresponding MSMerge_tombstone , MSMerge_Contents (depending on Delete\Insert\Update) and MSMerge_GenHistory tables.

Following query determine the changed rows and in which container they exists (In MSMerge_Contents)

select <YourTable>.*
from <YourTable>
inner join MSmerge_contents on tCustomers.rowguid = MSmerge_contents.rowguid
inner join MSmerge_genhistory on MSmerge_contents.generation = MSmerge_genhistory.generation


Below code finds the pending changes in merge replication.

select <YourTable>.*
from <YourTable>
inner join MSmerge_contents on tCustomers.rowguid = MSmerge_contents.rowguid
inner join MSmerge_genhistory on MSmerge_contents.generation = MSmerge_genhistory.generation
where MSmerge_genhistory.genstatus = 0

That's very helpful, thanks.  How can I find which tables Tablenick refers to in MSmerge_contents?

Also, to find which database updated which (publisher or subscriber) I should run the queries on both databases?
