Sometimes, while working in Microsoft SQL, it issues warning messages. A possible database corruption is the reason behind such alarming messages. Though many users ignore such messages and start experimenting with the database, which results in harsher instance of data loss or inaccessibility. Therefore, when your valuable data is lying in the database, handle it with extreme care and it would be wise to use any reliable SQL repair utility to repair the database and recover the data back.

After encountering the error or warning message, which gets flashed every time you try to open the database, the tables in the MS SQL database becomes completely inaccessible. Moreover, repeated occurrence of the error may result in more complex corruption of the SQL database. The error message that you may have come around can be as read as below:

Warning: Page P_ID, slot S_ID in Object O_ID Index I_ID Column COLUMN_NAME value COLUMN_VALUE is out of range for data type "DATATYPE". Update column to a legal value...

Most of the companies use Microsoft SQL server database for storing their database where database administrator handle all the issue for maintaining the database by the use appropriate SQL server commands. Microsoft SQL server database may be corrupted by Improper system shutdown, hardware failure, SQL Server malfunctioning, virus infection, hardware failure and many more. Once SQL server database gets damaged, the data stored in the SQL Server become inaccessible. In such scenarios, use latest and updated backup, if backup is not updated, then database administrator needs to used a third party SQL recovery software to repair mdf file.

Consider a situation, wherein a database administrator is working on SQL Server database and creating a report. While doing this, the Windows automatically restarts due to power failure. When database administrator restart the system, the SQL server database becomes inaccessible. When the database administrator tries to attach MDF manually, he encounters the given below error message:...

The metadata structure of SQL Server database comprises of numerous Index pages, which further consist of data pages. The data pages at each level of Index page are linked in a doubly-linked list. Inaccessibility of data stored in the data pages primarily occurs due to breaking of linked list (metadata structure corruption). Additionally, it also results in unmountability of the database. Few main reasons for metadata structure damage are improper system shutdown, virus hits, or physical damage. An easy solution to overcome the metadata structure corruption situation, you will need to restore the data from an updated database backup. However, with case studies proving that database users tend to forget to create an updated database backup, it is always handy to take help of third-party sql database repair applications.

Picture a scenario, where you receive the below error message while you attempt to mount your SQL Server database:...

In MS SQL Server, the CHECKTABLE command is used to check the integrity of the database tables. To do this, it uses several parameters to perform different types of checks. However, if the table is corrupt then this command may not work and exit abruptly. Such database corruption may cause because of several issues including virus infections, hardware malfunctioning, etc. These cases can well be solved using appropriate corrective measures failing which you should use a third-party MS SQL repair software to do the needful.

Consider a scenario in which you are running the CHECKTABLE tool on a database in MS SQL Server 2000. However, the tool fails to execute and exits abruptly showing the following error message.

"CHECKTABLE terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors."

Cause:...

Structured query language (SQL) is a database computer language designed for managing data in RDBMs developed by Microsoft corporation. It has two primary query languages, ANSISQL and T-SQL. It offers the facility to access SQL Server database from anywhere, be it from your desktop or data center. It also provides combined services to search, query, report synchronize and analyze the database records. Sometimes it may happen that the SQL Server is unable to run. It may possible that the master database of SQL Server has gone damaged. This can be possible because of several reasons such as human errors, virus infections, power outages while SQL Server was open. In that case, you should replace the damaged database with its clean and backup. However, if the backup is not clean and updated then you should use an advanced sql recovery software to recover SQL database.

Consider a case wherein you have Microsot SQL Server installed on your machine. When you try to log on to the SQL Server, you are unable to do and an error message is appered, that is:...

A page header in a database page is the first 24-bytes of the page that contains the general information about the page such as the details about the free space pointers. It is, thus, a significant part of the database page, which can pose problems if it gets damaged. The page header damage is possible in different circumstances such as virus infections, unplanned system shutdown when the database is open, power outages, etc. In such cases, you should repair SQL database using appropriate corrective measures. However, if these methods do not work for the database then you should use a third-party MS SQL repair software to perform SQL database recovery.

Let us consider a situation wherein you are getting the following error message while working on the MS SQL Server 2000 database:

"Table error: Allocation page P_ID has invalid PAGE_TYPE page header values. Type is TYPE. Check type, object ID and page ID on the page."

Cause:...

An IAM (Index Allocation Map) is a page in the database that stores one bit per extent in all the GAM (Global Index Map). A set bit is used to point out that the extent is allocated to that particular index. At times, this convention is not followed as two IAM pages refer to the same GAM interval. Lot of times, this problem is caused due to database corruption, which in turn, can occur because of virus infections, database header corruption, abrupt or unplanned system shutdown, etc. There are several methods that can be used to achieve MDF file recovery. However, if you fail to do so then you should use a third-party SQL recovery software to do the needful.

Let us assume a situation in which you are getting the following error message while working on the MS SQL Server 2000 database:

“Table error: Multiple IAM pages for object ID O_ID, index ID I_ID contain allocations for the same interval. IAM pages P_ID1 and P_ID2.”...

MS SQL Server database is build up of various metadata structure components like, pages, extent, etc. Pages are the smallest unit of data storage that store actual data. A combination of 8 adjacent pages makes an Extent. Corruption or damage in metadata structure primarily results in inaccessibility of records stored in your database. In most of the database corruption situation, you encounter an error message stating the cause for the error. For successful access of records stored in your database and overcoming hazards created by error message, an easy way is to restore the database records from an updated backup. But if in case, your backup file has been corrupted, damaged, or unreadable, then you will need to use advanced repair software that can comprehensively repair MDF files.

Consider a practical case, where you encounter the below error message when you attempt to access the records stored in your MS SQL Server database:

"Table error: Extent P_ID object ID O_ID, index ID I_ID is beyond the range of this database."...

You must have encountered the table error messages while accessing the MS SQL Server database tables. These errors occur because of some integrity issues in the database tables. Sometimes, the integrity issues can take place because of having a corrupt database. And a database can get corrupted because of various internal and external issues such as virus attacks, human errors like improper system shutdown especially when the database is open, sudden power fluctuations, data integrity issues due to mishandling the database such as changing the structure of the database, multiple users trying to change the database table simultaneously, etc. Because of the table errors you can face various problems such as partially or completely inaccessible database, retrieving corrupt records, regularly displaying error and warning messages, and so on. These problems are bound to pose serious threats especially when you are working on a real-time environment. To counter such situations, you can restore the database by overwriting it with its updated backup. However, if the backup is not the updated one then you will have to use the advanced SQL Database Recovery application to repair the corrupt database...
