MS SQL Server is an RDBMS which has provided users with all the essential yet critical elements of a database management system. It is widely used all over the world because of the numerous advantages it offers over various other database systems. Some of them include increased scalability and performance, advanced security controls, deploying and managing enterprise data, monitoring and tuning databases in an effective way etc. Despite these significant achievements, this database is prone to corruption. Corruption in SQL Server database is encountered primarily due to virus infections, operating system errors, multiple user access of the database, read or write errors etc. As a consequence, all the important SQL tables and other components present in the database become inaccessible. To overcome the problem, you need to go for
SQL recovery through a reliable third-party tool...

Database indexes are very similar to the page numbers of an encyclopedia or the keyword index used at the back of an encyclopedia. They sort the records present in a database table and help to increase the performance of the database by enabling faster 'SELECT' queries. But, these indexes may get corrupt due to several reasons, such as improper shutdown, human errors, system crashes, abrupt closing of the application etc. This could make your database corrupt and may require you to go for database recovery. Corrupt database indexes may lead to an improper functioning of your database system. You may also see a few incorrect results in the output window for some queries. It may also prevent you from accessing the valuable data stored in your database file. To overcome this situation, you need to perform SQL repair of your corrupt database through a third party utility.
Sometimes, you might have seen the following error message in the MS SQL Server 2000 error log after trying to modify a database table:...

The B-trees in the database systems are the data structure that help in storing data in sorted order. As the data is stored in the sorted order, you can easily perform certain database tasks such as adding new records, deleting existing records, searching and retrieving data with lesser turnaround time. These b-trees have certain rules laid out using which all the operations are performed. At times, some nodes in the tree fail to comply with them because of database corruption, thereby damaging the database. In such cases, you should use the in-house methods to repair MDF file, failing which you should resort to using third-party
sql repair software to do the needful.
Let us consider a situation in which you are getting the following error message while working on the MS SQL Server 2000 database:
“Table error: Object ID O_ID, index ID I_ID B-tree level mismatch, page P_ID1. Level LEVEL1 does not match level LEVEL2 from parent P_ID2.”...

Database corruption in SQL databases can amount to huge losses depending upon the size of your organization. Because of database corruption, you would not be able to access the databases, work on them, and most importantly all the stored records would become vulnerable. But there are certain in-house workarounds that would enable you to perform mdf recovery. However, if these methods do not work then you should use a third-party
sql database recovery software to repair the damaged database.
Consider a situation in which you are facing the following error message while working on an MS SQL Server 2000 database:
“Table error: Object ID O_ID, index ID I_ID, page P_ID, row S_ID. Test (TEST) failed. Values are VAL1 and VAL2.”
Cause:
The most prominent reason for this table error is that the a record has failed while auditing as corruption is detected in its record header.

DBCC CHECKALLOC is a common command that is used by database users to check the consistency of disk space allocation. The command comprehensively examines the use and allocation of all pages in your specified database. However, if examining the pages, the command displays an error message, then it means that your database pages have been corrupted or damaged. Furthermore, the data stored in the database becomes inaccessible after the error message appears. An ideal way to access your data in such situations is by restoring the data from an updated backup. But if in case, your database backup has been corrupted or damaged, then you will need to use advance SQL Repair application to repair your database.
As a practical instance, you encounter the below error message when you run DBCC CHECKALLOC command:
"Table error: Page %S_PGID is allocated to object ID %d, index ID %d, not to object ID %d, index ID %d found in page header."
After the above error message appears, the data stored in the database becomes inaccessible...

In MS SQL Server database, a page is used as the most primitive unit of storage as the space allocated to every database file. And a collection of eight pages is called an extent, which is used to manage the pages. However, sometimes SQL Server is unable to read through the properties of these pages. Such problems can invariably occur due to various issues such as virus infections, power outages, hardware problems, abrupt system shutdown when the database is open, etc. In such cases, you should find out the exact cause of corruption and try to isolate it. If any of the methods do not succeed, then you should use a third-party SQL repair software to
repair SQL database.
Consider a scenario wherein you encounter the following error message while working on an MS SQL Server 2008 database:
"
Process ID %d attempted to unlock a resource it does not own: %.*ls. Retry the transaction, because this error may be caused by a timing condition. If the problem persists, contact the database administrator."...

As you store more and more data to your Microsoft SQL Server database, the size of database increases and the performance of Microsoft SQL Server decreases day by day. Large size of database may also cause system crash and sometimes database corruption. To prevent such situations, MS SQL Server provides SHRINKFILE and SHRINDB tools for reducing size of the database. However, in some cases, these tools fail to shrink the database and problem remains intact. At this point, if database corruption occurs, SQL database repair becomes need of hour.
As a practical example of this behavior, you may come across the following error message when you try to reduce size of the SQL Server 2000 database using SHRINKFILE, SHRINKDB, or SQL Server Enterprise Manager:
"2002-11-25 22:41:30.18 spid55 Time out occurred while waiting for buffer latch type 4,bp 0x3d03340, page 1:37939357), stat 0xb, object ID 8:8:0, EC 0xB39B55E0 : 0, waittime 300. Not continuing to wait...

An IAM (Index Allocation Map) page consists of eight page Ids, collectively called mixed page array, and holds the pages that are allocated to the index. The IAM pages are used to optimize the tables by allocating and deallocating storage space. Sometimes the IAM page is not able to perform as expected. Such corruption instances can occur because of various reasons such as hardware malfunctions, virus infections, power outages, abruptly exiting SQL Server, etc. To resolve such situations, you should use appropriate corrective measures. In case, you are not able to recover SQL database then you should use a third-party
SQL database repair software to do so.
Consider a scenario wherein you encounter the following error message while working on an SQL Server 2000 database:

In Microsoft SQL Server, if any transaction violates the integrity constraints during execution, database inconsistency occurs. The transaction leaves your MS SQL Server database in illegal state and it gets aborted with an error. Database inconsistency leaves your MDF (Master Database File) in an unusable and inaccessible state, which can lead to serious data loss. In such cases, a valid and updated backup come for your rescue. You can easily restore all your valuable data from current backup and prevent needs of
SQL recovery using third-party applications.
However, in case you are unable to restore data from the backup or backup is incomplete, you can check the database errors and fix them using inbuilt utility of Microsoft SQL Server, called CHECKDB. It offers you an option to repair the database errors. Database inconsistency may also occur due to system level errors, like file system and hardware. You are highly recommended to fix these errors before repairing the database, else you may face the same problem again after some time...

The tempdb database is one of the system databases in SQL Server. It is used to store the temporary tables, table variables, etc. The tempdb is recreated every time SQL Server is started. This way, the system always starts with a fresh copy of the tempdb database. However, sometimes the tempdb gets corrupt because of various issues such as power outages, virus infections, human errors, abrupt system shutdown, etc. In such cases, you should take appropriate corrective measures to resolve the issue. However, if you are not able to do so then you should use a third-party
MS SQL repair tool to repair SQL database.
Consider a scenario wherein you are performing allocation checks on the tempdb database. But the process terminates abruptly and an error message is displayed, that is:
“Database tempdb allocation errors prevent further CHECKNAME processing.”

MS SQL Server database user might encounter database corruption issues due to improper system shutdown, metadata structure damage, human mistake, and virus infection. In most situations of database corruption, the database user encounters an error message while trying to mount his/her database. The records saved in the database become inaccessible after any such mount error flashes on the screen. To surpass such error messages and to access the database records, the user can run an inbuilt repair command – DBCC CHECKDB. The command checks the logical and physical integrity of the database and resolves logical corruption to the maximum level. However, there are certain situations where the command fails to resolve logical damage. For such cases, the user needs to opt for an effective third-party
SQL Database Repair application.
To explain the above scenario, consider the underneath error message that appears when you try to repair the database using DBCC CHECKDB command:...

In MS SQL Server database, a PFS (Page Free Space) page has one byte for each of the pages existing in the file interval it maps. This byte contains a bit that indicates that the associated page is a mixed page. An IAM page includes a mixed page array, which is an array of eight page IDs, to keep the mixed pages that have been allocated to the index. In some cases, when the database goes corrupted, the page containing 'mixed page' bit is not recognized correctly. Thus, you can detect such specific cases of database corruption and, take corrective measures for
MS SQL Repair.
Most of the SQL database corruption problems can be analyzed and detected by running DBCC CHECKDB command. Let's consider the below error message, which typically appears when the discussed problem occurs. When you run DBCC CHECKDB command to check the integrity of database, following error might pop up:

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.”...
