Symptoms
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.
Resolution
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.
Symptoms
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.
Resolution
Consider the following scenario:You start a SQL Server Extended Event session in Microsoft SQL Server 2008 R2.You perform actions that are bound to events in the Xevent session on a case-sensitive database.In this scenario, SQL Server may crash, and then a mini-dump file is generated. Additionally, the following exception is logged in the SQL Server error log file:?
Exception 0xc0000005 EXCEPTION_ACCESS_VIOLATION
Symptoms
Executing a SELECT * FROM SYSINDEXES query against a database that has been upgraded from Microsoft SQL Server 7.0 may cause an Access Violation. If an Access Violation occurs, an error message similar to the following displays in the query window:
ODBC: Msg 0, Level 19, State 1
SqlDumpExceptionHandler: Process 51 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
Server: Msg 1203, Level 20, State 1, Line 1
Process ID 51 attempting to unlock unowned resource KEY: 7:2:1 (790023da5d09).
Resolution
The maximum length defined for the keys column in the sysindexes system table in SQL Server 2000 is 1088, while in SQL Server 7.0, it is only 816. When a database is upgraded from SQL Server 7.0, the maximum length defined for the keys column is not updated. As a result, when an index whose keys column exceeds 816 bytes is created and the index is subsequently fetched, as in a SELECT * FROM SYSINDEXES query, the prefetch buffer is written past the 816 bytes that have been allocated, which causes the Access Violation.
Symptoms
When you execute an INSERT, DELETE or UPDATE query that operates on objects with underlying triggers, the query may terminate with the following error message and an Access Violation occurs:
ODBC: Msg 0, Level 19, State 1
SqlDumpExceptionHandler: Process 52 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.The Access Violation may occur when the following conditions are true:The table has underlying triggers for the INSERT, UPDATE or DELETE.The trigger queries the inserted or deleted trigger tables.The NO_BROWSETABLE option is set ON.The following stack dump appears in the SQL Server 7.0 error log:
