SYMPTOMS

Consider the following scenario:
  • You have a merge replication that is configured to use Web synchronization in Microsoft SQL Server 2008.
  • You replicate several columns, and at least one of the columns contains a NULL value. This column that contains the NULL value is not the last column that is replicated.
In this scenario, the columns are not replicated correctly. 

For example, you try to replicate four columns that contain values of the XML data type, and the first column contains a NULL value. In this scenario, the last column is not replicated.

CAUSE

This issue occurs because Web synchronization counts only the columns that have no NULL values.
