Are you facing Access Violation error in MS SQL Server? Are you unable to access the database and its objects? Access Violation is a situation where application can not access the data because the data is either damaged or the application does not own the data. In both the cases, your database remains inaccessible and unusable. This behavior may lead to significant data loss and needs to be fixed.
In a practical scenario, consider:
In MS SQL Server 2008, a query contains the following clauses:
The database query uses parallel execution plan.
You execute the query.
In this case, you may come across an Access Violation. Additionally, you may encounter the below error message:
Expression: 0 != pxteBitmap
Msg 3624, Level 20, State 1, Line 2
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
After the above error, database can not be accessed. In order to gain access of your SQL Server database, you need to carry out SQL Server Recovery by fixing this behavior.
As stated in the error message, you may have encountered such situations due to application malfunction or database corruption. Database corruption may occur after virus infection, unexpected system shutdown, operating system malfunction, and other similar situations.
Consider running DBCC CHECKDB command to get your database repaired. It is an inbuilt utility in SQL Server that checks integrity and consistency issues of MDF (Master Database File).
However, if this tool can not fix the problem, third-party software are always there for your help. These are advanced tools, which methodically scan entire database and ensure absolute SQL Recovery in most of the database corruption situations.
SQL Recovery is the most efficient tool to ensure absolute recovery of your damaged database. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all database objects such as tables, reports, forms, queries, stored procedures, triggers, and constraints.
