FIX: Access violation or incorrect result when you insert data into or update a new partition of a partitioned table in SQL Server 2008 R2, SQL Server 2012 or SQL Server 2008

Consider the following scenarios:

Scenario 1

• You drop a column of a partitioned table in Microsoft SQL Server 2008 R2, Microsoft SQL Server 2012, or Microsoft SQL Server 2008.
• You create a new partition for the table.
• You try to insert data into the new partition of the table.
• You switch partitions for the table.
• You try to insert data into the new partition of the table.

In this scenario, an access violation may occur. Additionally, you receive the following error message:

Scenario 2

• You have a partitioned table in SQL Server 2008 R2, SQL Server 2012, or SQL Server 2008.
• You change the compression type of a partition.
• You try to update the partition or insert data into the partition.

In this scenario, an access violation may occur. Additionally, you receive the following error message:

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 fewer than the number of the maximum nullable columns in the old partition.
