SQL Server Q&A

Symptoms
Running a complex query that results in a parallel plan may cause an Access Violation (AV) to occur.

Symptoms
If you run a SQL Server Data Manipulation Language (DML) statement from a DB-Library based application against a Microsoft SQL Server 7.0 server, the error handler for the application may incorrectly fire and only report the following error message:

DB-LIBRARY Error 10007, Severity 5:
General SQL Server error: Check messages from the SQL Server.Note that this error message accompanies a wide range of SQL Server errors that are reported back to the client from the server. However, in this scenario the preceding error message is the only error reported and it is not accompanied by any other specific error messages.
Resolution
If a parallel hash join produces an empty result set, internal exception 3602 is used to coordinate the shutdown of worker threads that were created to process the parallel hash plan. The internal 3602 exception is an internal control exception that is used to direct processing flow inside SQL Server and is expected behavior in this case.
However, the fact that it is causing an error to be sent back on the client connection, which in turn causes the DB-Library error handler to fire is not expected behavior.

Symptoms
When restoring the backup of a database, which is enabled for Transactional and Merge Replication (Sysdatabases.Category = 5), to a non-published database on a different server, the merge replication system tables are not dropped and the user tables on the destination server’s database cannot be dropped. If the backup is restored on the same server (different database), then the restore works fine and the replication information is removed.
Also, the restore works fine across servers when the source database is enabled either for Transactional or Merge Replication only (Sysdatabases.Category = 1 OR 4).
Resolution
To work around this problem, you can either:Enable the source database for Transactional or Merge Replication alone (Sysdatabases.Category = 1 OR 4).
-or-Drop the merge system tables using the DROP TABLE syntax.NOTE: Contact Microsoft Product Support Services if you need to drop the user tables and are unable to do so.

Symptoms
The merge agent fails with the following error message:

The remote procedure call failed and did not executeThe task reports the preceding remote procedure call (RPC) failure in its history, which can be misleading because there are not any other connectivity problems. The merge agent runs into a handled exception with the following stack, as seen in the replication exception log file:

The Exception Stack Dump follows:
ntdll77f67546RtlpWaitForCriticalSection
ntdll41d70871RtlEnterCriticalSection

replmerg004038e2CReconcilerTask::Reconcile
replmerg00407af8AgentRun
replmerg08ec83ecAgentMain

Resolution
The RPC failed message is the result of a exception with the merge agent. Replmerg.exe fails while inserting generation history, generating an exception when completely filling the allocated memory buffer. This causes an out of space situation and the required null termination character cannot be added, subsequently causing the access violation.

Symptoms
An invalid use of the Getdate function within a function may cause an access violation and the following error message appears in Query Analyzer:

Server: Msg 443, Level 16, State 1, Procedure fnTestDate, Line 4
Invalid use of ‘getdate’ within a function.
ODBC: Msg 0, Level 19, State 1
SqlDumpExceptionHandler: Process 51 generated fatal exception c0000005
EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
Connection BrokenYou may find the following error messages in the SQL Server error log when the access violation occurs:

Symptoms
Inserting certain Unicode strings into a SQL Server 2000 Windows CE (SSCE) table might cause an SQL INSERT command to fail with an application error, or the application might stop responding (hang) while other programs remain responsive. The symptoms of the problem can vary, but may include messages similar to:

Application <Executable file name> has performed an illegal operation and will be shut down. Fatal Exception 0xC0000005
