• Table error: Object ID 0, index ID 0, page ID (1:105). The PageId in the page header = (0:0).
• File: , line=466 Failed Assertion = '0'.
• Table Corrupt.
• Conflict occurred in database‘db_name’, table 'table_name', column 'column_name'
• Memory or buffer error, space provided to read column is too small.
• Internal errors

SQL Server Database Consistency Check Errors are Reported by DBCC CHECKDB

Microsoft SQL Server includes an inbuilt utility, called DBCC CHECKDB, to check the consistency and integrity of MDF (Master Database File). However, sometimes the DBCC CHECKDB process does not complete successfully and can not fix the associated issues. Database inconsistency can make the SQL Server database inaccessible and lead to severe data loss situations. In such cases, you need to recover SQL database, in order to extract data from it. When you execute DBCC CHECKDB on an SQL database, an error message similar to the following one, appears in ERRORLOG of Microsoft SQL Server- “2010-03-31 22:07:06.34 spid53 DBCC CHECKDB (mydb) executed by MYDOMAIN\theuser found 15 errors and repaired 0 errors. Elapsed time: 0 hours 0 minutes 0 seconds. Internal database snapshot has split point LSN = 00000026:0000089d:0001 and first LSN = 00000026:0000089c:0001. This is an informational message only. No user action is required.” The above message shows the total number of database consistency errors in SQL database and how many of them are repaired. The message information, start from 'internal database snapshot...', appears only if you run the DBCC CHECKDB online. The database consistency check process is halted with this error message and your database remains inaccessible. To gain access of your valuable data, SQL database recovery is required. Root of the problem: DBCC CHECKDB utility checks the logical and physical consistency of SQL Server database pages, allocation pages, rows, system table referential integrity, index relationships, and other database structure checks. In case any one of these checks does not complete successfully (depending upon the options that you have selected), errors are reported as part of this command. This behavior may occur due to numerous reasons of database corruption, such as hardware system problems, file system corruption, damaged pages in memory, or issues with MS SQL Server Engine. Resolution: The most excellent solution to fix DBCC CHECKDB consistency errors is to restore the database from the most recent backup. However, if backup is not available or updated, CHECKDB offers an option to repair the errors. When all else fails, SQL recovery software are required to repair and restore the damaged SQL Server database. They employs high-end scanning techniques to thoroughly scan entire database and extract all of its inaccessible objects. The MS SQL recovery tools are pretty safe and easy to use. Stellar Phoenix SQL Recovery software repairs damaged or corrupt SQL Server database and restores it to default or user-specified location. It is usable with Microsoft SQL Server 2008, 2005, and 2000. The software extracts all items from SQL Server database, such as tables, reports, macros, forms, stored procedures, triggers, and constraints.

Fixing 2537 Corruption Errors in SQL Server Reported by DBCC CHECKDB

Microsoft SQL Server is one of the most widely accepted RDBMS (Relational Database Management System), developed and marketed by Microsoft Corporation. It stores your mission-critical data in a database, which has two major data files - MDF (Master Database File) and NDF (Next Database File). In some situations, the SQL Server database may encounter inconsistency issues and become inaccessible. This behavior renders your precious data inaccessible and causes serious data loss. In order to overcome such issues, you need to go for SQL database recovery alternatives.

Microsoft SQL Server provides DBCC CHECKDB tool for checking the consistency and integrity of the database. It may report the inconsistency of the database if all the below mentioned conditions are true:

• MS SQL Server loads the data to any column with sql_variant data type.

• There are some character values in sql_variant column.

• The information is sent either to another SQL Server directory or through intermediate file.

• The information develops in some other column with sql_variant data type, and simultaneously it is sent by SQL Server on-the-wire.

The DBCC CHECKDB statement may report you the following corruption error:

“Msg 2537, Level 16, State 43, Server MYSERVER, Line 1 Table error: Object ID 1977058079, index ID 0, page (1:75), row 0. Record check (Valid SqlVariant) failed. Values are 4 and 0. DBCC results for 'MyTable'. There are 0 rows in 1 pages for object 'MyTable'. CHECKDB found 0 allocation errors and 1 consistency errors in table 'MyTable' (object ID 1977058079). CHECKDB found 0 allocation errors and 1 consistency errors in database 'MyReproDest'. repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (MyReproDest ).”

Cause:

This problem occurs due to corruption of the Microsoft SQL Server database table or entire database. You should not run the REPAIR_ALLOW_DATALOSS statement on such databases as it may remove the affected data.

Resolution:

In order to recover SQL Server database in such cases, you should try restoring the database from updated backup. Backup is the easiest and the most effective way to prevent data loss.

However, in case backup is not updated or available, commercial SQL Serverrecovery software becomes need of hour. The advanced third-party tools enable you to scan entire database using powerful MS SQL recovery scanning algorithms and restore entire database.

DBCC CHECKDB Displays 8929 Error Message

MS SQL Server database users use DBCC CHECKDB command to repair their logically damaged SQL databases. This command can be used with different 'repair' parameters, such as, repair_allow_data_loss, repair_fast, and repair_rebuild. While the command used with the above parameters performs maximum repair in most database corruption cases, there might be few instances, wherein the command fails to resolve the corruption issues. In such cases, the output of the command is an error message, which states the exact cause for failure of DBCC CHECKDB command. After the occurrence of DBCC CHECKDB command failure error message, the database remains unrepairable, further resulting in inaccessibility of saved records. To overcome such SQL database corruption scenarios and successfully access the records saved in the database (in case no backup is available), the user needs to opt for a commercial SQL Database Repair application. Below is one such error message that appears when the user DBCC CHECKDB command fails to repair a corrupted MS SQL database: “Server: Msg 8929, Level 16, State 1, Line 1 Object ID 2: Errors found in text ID 852426752 owned by data record identified by RID = (1:110:19) id = 1925581898 and indid = 2. Server: Msg 8965, Level 16, State 1, Line 1 Table error: Object ID 2. The text, ntext, or image node at page (1:438), slot 3, text ID 852426752 is referenced by page (1:71), slot 4, but was not seen in the scan. DBCC results for 'PDP'. DBCC results for 'sysobjects'. There are 652 rows in 11 pages for object 'sysobjects'. DBCC results for 'sysindexes'. There are 480 rows in 18 pages for object 'sysindexes'. CHECKDB found 0 allocation errors and 2 consistency errors in table 'sysindexes' (object ID 2). DBCC results for 'syscolumns'...” After the above severity level 16 error message appears, the database records become inaccessible. Cause: The primary reason for the occurrence of above error message is severe corruption in MS SQL database. Resolution: To resolve the above error and mount your database, you will need to repair the database using a commercial SQL Database Repair software. A MS SQL Repair utility assures maximum repair of SQL database, irrespective of its level of corruption. SQL Recovery Software is a complete solution for repairing logically damaged MS SQL Server 2008, 2005, and 2000 database. It is competent enough to recover almost all database components after repairing. The read-only tool SQL Repair does not make any change in the original database. It can be installed on Windows 7, Vista, 2008, XP, 2003, and 2000 operating systems.
