How To - Fix Stored Procedures Corruption in MS SQL Server?

Are you encountering errors while executing stored procedures in Microsoft SQL Server database? Is stored procedure not producing correct outputs? The problem may occur due to corruption of the stored procedures. After corruption, the database may not function correctly and you will need to repair it. In some cases, corrupt stored procedures may even damage the database if they perform improper database functions. In both these cases, you need SQL Database Recovery applications to get your database repaired.

• Stored Procedure is in fact a set of Transaction- SQL (T-SQL) statements, which are compiled in a single query execution plan. It works like a construct in programming languages. The stored procedure has a number of advantages, such as pre-compiled execution, enhanced security controls, reduced client/server traffic, effective reuse of programming abstraction and code, and many more.

You can use the stored procedure to run a sequence of the SQL statements on conditional logic. If the conditional logic and the SQL statements are written in stored procedures, they become a part of a single execution plan. However, in this case if any of the stored procedure gets damaged, you may come across a number of critical database corruption situations.

Corruption of the stored procedures may degrade the efficiency of MS SQL Server database and produce bad output. The function that needs to be executed using stored procedures might come down. This behavior usually makes the SQL Server database fragile. Stored procedure corruption may be indicated through a number of error message, similar to the following ones:

“Error 0:[SQL-DMO]Object 'dbo.SP_ProcName' was not scripted. It is possible that the information in system table 'syscomments' about the object was corrupt or missing?”

Or

“Incorrect key file ... try to repair it”

SQL Server database stored procedures may occur due to virus infection, improper system shutdown, application malfunction, improper command execution, and many alike. Irrespective of the cause of this problem, data loss occurs and SQL Recovery is required.

You can easily Recover SQL database with the help of third-party SQL Server Recovery applications. They come equipped with highly-advanced and efficient scanning techniques to ensure absolute recovery of damaged SQL database. The software are built-with simple and self-descriptive graphical user interface to provide ease of use.

Rectifying Error 5228 in SQL Server 2008

When you use the DML (Data Manipulation Language) commands to update the database, the rows sometimes get in an intermediate state. It is called the antimatter state that enables concurrent DELETE statements to leave a pointer for the index builder transaction so that deleted rows are not inserted again. Ideally, these rows should be deleted at the end of the operation. However, sometimes it does not happen that invariably results in database corruption. To resolve this situation, you should use appropriate corrective methods. However, if you are unable to do so then you should use a third-party SQL Server recovery software to address the issue.

Consider a scenario wherein you are working on a table in SQL Server 2008. You get the following error message while performing some modifications on the database table:

“Table error: Object ID O_ID, index ID I_ID, partition ID PN_ID, alloc unit ID A_ID (type TYPE), page PG_ID, row R_ID. DBCC detected incomplete cleanup from an online index build operation. (Antimatter column value is VALUE.)”


Cause:

The root cause of this error message is that for the O_ID object , I_ID index, and PN_ID partition, there is an unfinished online index build was detected. This is testified by the presence and the displayed value of an antimatter column on the R_ID row.

Resolution:

To resolve this error message, you should perform the following methods, preferably in the given order:

Check for hardware issues: You should run the hardware diagnostics and check if the error appeared because of any hardware issue. You can also try to swap the hardware components to zero in and resolve the issue. In addition, you can try to reformat the disk and reinstall the operating system.

Restore from backup: Check if you have a clean and updated backup of the database. If yes, then you should restore the database with its backup.

Run DBCC CHECKDB: As a last resort, you should run the DBCC CHECKDB command without the repair clause to ascertain the level of the corruption. You should run the command again after knowing the repair clause. It will rebuild the corrupted indexes.

However, if you still are not able to resolve this error by any which method then you should use a third-party SQL recovery software. Such read-only tools are able to recover SQL database using sophisticated scanning algorithms without overwriting the original data.

Resolving Error 5171 in SQL Database

SQL database corruption can occur due to SQL Server malfunctioning, virus infection, improper system shutdown, hardware failure and many more. Once the MS SQL database gets corrupted, the SQL database become inaccessible. In such situations, use you backup, if there is no backup, the user needs to repair mdf file by using advanced SQL MDF Repair application. Consider a practical scenario, where a user is working on SQL Server 2005 and creating a report. While doing so, the Windows restarts due to power failure. When user restart the system, the SQL database becomes inaccessible. When the user tries to attach the MDF manually, he encounters the below error message:

“An exception occurred while executing a Transact-SQL statement or batch. _db.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171).” Or

“C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\MYDATABASE.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171)” In such circumstances, the database administrators recommend to attach a single file. However, when the user uses sp_attach_single_db Stored Procedures, the user encounters the following error message:

“Server: Msg 5172, Level 16, State 15, Line 1 The header for file path……\.mdf is not a valid database file header. The PageAudit property is incorrect.”

The above error message encounters due to MDF file corruption. The above issue occurs when the MDF file header gets corrupted or some invalid information is inserted in the header file. All these situations result, inaccessibility of the SQL database. To ensure accessibility of the SQL database, the user needs to recover it by using the latest backup. But sometime user has not created any backup of its database or mdf file, then he needs to perform MDF repair. To do so, user needs to use efficient and effective MDF repair application. Such mdf file repair applications incorporate advanced and powerful scanning algorithms to repair the corrupted MDF file. The mdf recovery software perform systematic scan of corrupted MDF files, repair and restore them in their original format without altering any information.

Troubleshooting Error 8999 in SQL Server

All the users connected to the SQL Server instance have access to a global resource called tempdb system database. This database holds temporary user objects, internal database objects, and row versions that result from data modification. At times, when some allocation checks are performed on this TEMPDB database, they may result in allocation errors and unexpected results. Since TEMPDB cannot be put in offline mode, no fixes are possible for allocation errors in this database. However, for rest of the SQL databases, you can perform MS SQL Repair using suitable tools and utilities.

For exemplifying the given problem, consider, you might start receiving unexpected database access problems in MS SQL Server database. To determine the exact cause of the problem, you run CHECKDB command and the below error message pops up:

“Database tempdb allocation errors prevent further CHECKNAME processing.”

This error message is recorded with error number 8999 and severity level 10.

Cause

The above error results specifically when the entire check operation terminates because of allocation error in TEMPDB.

If database is still corrupt, the root cause of corruption is hardware problems.

Solution

To resolve the issue, you should:

Diagnose the SQL Server™ error and Microsoft® Windows NT® system log for determining if the problem has actually resulted due to hardware problems. You can also run hardware diagnostics and fix related concerns by, swapping the hardware components or installing a new hardware system etc.

restore the database from the last available backup, if hardware issues have not been the problem.

Run DBCC CHECKDB and determine the extent of database damage, in case no suitable backup is present. Later, you can run the same command but with a suitable SQL Repair clause to fix database corruption. However, you should backup the database before executing database repair as data loss is likely.

Run MS SQL Repair software for repairing corrupted SQL database. These utilities generally repair the database after any type and extent of damage.

Repairing SQL Server master database – Error 3417

SQL Server is a relational database management system (RDBMS) by Microsoft that is designed for the enterprise environment. It has got two primary query languages, T-SQL and ANSISQL. It provides you the flexibility to access your database from anywhere, be it from a data center, desktop, or from a mobile device. It also provides combined services to query, search, synchronize, report, and analyze the database records. However, at times it may happen that the SQL Server is unable to run. It may be possible that the master database has gone corrupt. This can be possible because of various reasons such as virus infections, human errors, power outages or abrupt system shutdown while SQL Server was open. In such cases, you should replace the corrupted database with its updated backup. However, if the backup is not updated then you should use a third-party SQL Database Recovery software to recover SQL database.

Consider a scenario wherein you have MS SQL Server 2008 installed on your system. When you log onto the SQL Server, you are unable to do so. An error message is displayed, that is:

“Cannot recover the master database. SQL Server is unable to run. Restore master from a full backup, repair it, or rebuild it. For more information about how to rebuild the master database, see SQL Server Books Online.”

Cause:
The cause of the mentioned error message is that the SQL Server is unable to start the master database. If the master or tempdb database cannot be mounted, SQL Server cannot run. It is quite possible that the master database has gone corrupt because of various aforementioned reasons.

Resolution:
To resolve this issue, you should, first of all, check whether there is an updated backup of the master database. If yes, then you should replace it with the corrupted database. However, if the database is not updated then you should use a third-party SQL database recovery software to perform SQL Recovery of the corrupted database. Such read-only tools are able to recover SQL databases using fast yet sophisticated scanning algorithms.

SQL Database Recovery is an SQL Server recovery tool that enables you to perform SQL database recovery of the corrupted databases. It is able to repair various database components such as tables, defaults, stored procedures, triggers, views, and rules. It can also repair user-defined data types and functions and also database constraints such as primary key, foreign key, unique key, and check. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Incorrect Updating of System Tables Cause Database Corruption in SQL Server

When you create an MS SQL Server object, the properties of objects are known as metadata. SQL Server stores metadata in a special tables, known as System Tables. You can update these tables as per your requirement. It is quite easy to update system tables by defining the triggers. However, MS SQL Server automatically updates most of the system tables internally using inbuilt API. You should always create a complete backup of all the system tables, before you try to update them. If the update fails or you improperly update the table, your SQL Server database may get severely damaged and you need SQL Database Recovery to be fixed.

The system tables are automatically created by Microsoft SQL Server, when you create an object. For instance, Microsoft SQL Server 2000 stores all your data types and column names in the internal system table, known as 'syscolumns'. The metadata, stored in system tables, can be used to gather performance statistics, discover column and table differences and similarities while upgrading the database, and obtain lock information.

In Microsoft SQL Server 2005 and later versions, the System tables are hidden and cannot be queried like general database tables. These tables are restricted even for the user who have full Database Administrator privileges. Though, system tables are not accessible directly, but there are various inbuilt procedures and views to extract metadata from them.

After accessing the system tables and metadata, you can update them, if required. The update process can be used to add new options or to remove some existing options.

You should work safely while updating the system table. Incorrect or improper updating of SQL Server system tables may lead to severe problems, which might need to reinstall Microsoft SQL Server application. It may also damage the SQL Server database. There is no guarantee of successful updating. Before you prompt for updating system tables, you are highly recommended to create a good backup of SQL Server database.

In case SQL Server database gets damaged due to incorrect updating of system tables, perform SQL Server Recovery by restoring the database from backup.

If backup is unavailable, use MS SQL Recovery software to sort out the problem. The applications are specifically designed to thoroughly scan entire database and extract all inaccessible data from it. They perform simple and secure SQL Recovery with interactive design and read-only behavior.

SQL Recovery software repairs and restores damaged Microsoft SQL Server database in all cases of corruption. The software works well with MS SQL Server 2008, 2005, and 2000. It recovers all damaged SQL Server database objects, such as tables, views, reports, triggers, stored procedures, data types, and more.
