  • you might want to post your question to either the SQL Server forum or the SQL Compact forums as this is the Synchronization Framework forum.

    to answer your question very briefly, uniqueidentifier is a data type and am not sure how its going to help speed up your query in your scenario.

    how many rows do you have on your Pack table compared to your barcode table?
