FIX: Access violation when you insert data into a new partition of a partitioned table after you drop a column of the table in SQL Server 2008 R2

Microsoft distributes Microsoft SQL Server 2008 R2 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 R2 fix release.

Consider the following scenario:

• You drop a column of a partitioned table in SQL Server 2008 R2.
• You create a new partition for the table.
• You try to insert data into the new partition of the table.

In this scenario, an access violation may occur.

This issue occurs because the accessor that SQL Server uses to insert data into different partitions recognizes the metadata changes incorrectly. When data is inserted into the new partition that is created after a column is dropped, the number of the maximum nullable columns in the new partition may be one less than the number of the maximum nullable columns in the old partition.
