Additional issues that are fixed in this service pack 

Resolutions to the following issues are also included in SQL Server 2008 R2 SP2. VSTS bug numberDescription820845elated to usage of the BindParameter method and the reference of long type parameters that are used by this method. 852397Updates UpgradeIncompleteFeatureConfigEventHandler.cs to include RebuildDatabase scenario when you reset ConfigurationState.887672For document libraries with the "Opening Documents in the Browser" setting set to "Open in the client application," GetSnapshot.exe ignores the configuration and always displays the workbook by using Excel Services as if the setting was "Open in the browser." 820805FIX: On a Russian localized build of the Reporting Services Configuration Manager, Execution Account information contains clipped strings. 718430The ExpectedCount and ExpectedElapsedMs usage counts are updated to reflect the actual counts. 737914Fixes an issue in which SQL Server 2008 R2 Analysis Services crashes during database synchronization.788389Trace flag 1264 is removed so that the process name is collected by default in non-yielding scenario dumps. The number of thread records in non-yielding scenario dump files is increased from 1K to 16K.820762SQL Server 2008 R2 changes the FireAgain parameter to True if an event should be logged. However, after some codes are removed by mistake, some logs are missing because the FireAgain parameter is determined only by the external event listener. After you apply this hotfix, the issue is resolved.820764Consider the following scenario. You have indexed view projects columns from base and non-base tables in SQL Server 2008 R2. A column from the non-base table has the same order ID and type as a column of the base table. In this scenario, SQL Server 2008 R2 switches the partitions. After you apply the hotfix, SQL Server 2008 R2 experiences an error instead of switching the partitions. 820792Fixes an issue in which an object that is allocated on a SOS_Task PMO could be also used by another TASK that has a different life span. This service pack uses the correct PMO for allocating the object.820796After you apply the hotfix, the optimizer understands that CRYPT_GEN_RANDOM can return different outputs for the same input.820859Fixes an issue in which an incorrect value is returned when you run SCOPE_IDENTITY().820864Fixes an issue in which the SQL Server 2008 R2 setup crashes when you install SxS with Shiloh OLAP SP3a. This issue occurs because Shiloh OLAP SP3a incorrectly writes the version registry key as "Service Pack 3.0." 820873Fixes an issue in which an incorrect CPU time is reported by sys.dm_exec_query_stats when parallel query plans are involved.820880Fixes an issue that occurs when internal asynchronous file-reading buffers are splitting the multi-character column delimiter in two parts. The fix is to correctly reset the current parsing pointer after buffers are switched. 847805Uses the synchronization only if the SQLWixCompilerExtension operation runs in candle.890643Changes the HierarchyGet operation to avoid a certain code path for the explicit cap that applies only to the derived part of the hierarchy. The update is a one-line update that is low risk.731796Fixes an issue in which you receive errors in a statement when you purge from snapshots.notable_query_text.820829Bad GUID values that are parsed from flat files could cause errors. The fix is to fall back into a truncation mode if the source buffer is larger than the maximum size of a GUID string.677173Recalculates latch promotion threshold periodically to avoid variation because of a calculation error at startup.725819The suggested fix is matching calling conventions between caller and the person who is called.769975Fixes a crash during startup when the computer has an empty processor slots or the restart option /setgroupsize is used.788233Reduces the time during which the latch backs off when it experiences spinlock. This helps improve performance840461Fixes a race condition during XE session startup that could cause SQL Server crashes.
