SQL Database Recovery

SQL Database Recovery Software: A Perfect Solution to Fix SQL Errors

SQL Server, one of the powerful Relational Database Management System help users to brilliantly organize, manipulates and retrieves data. However, built up with foolproof algorithms, inconsistencies and troubles are faced by administrators that are indicated via error messages. Below given are some of the warning messages that are encountered by SQL Server users and how database corruption leads to SQL Recovery software need.

Import & Export Fail Due to SQL Corruption

Cause: In Microsoft SQL Server table, primary key defines the identity of a specific record that helps users to create a relation between databases. In a table, there can only be one primary key. If the row in table defining the primary key is orphan, that is it does not exist anymore for the table, two databases cannot be related and thus relational database management cannot be made possible. The reason behind the above error message is the same, i.e. orphan row having primary key.

Error 8931 While Trying To Export Results

What is the B-Tree Structure of Database? In SQL Server application, B-tree system helps to define database in a systematic order. When the database is stored in a sorted manner, users can easily perform some general activities like records deletion, new records addition, extracting specific data etc. with minimum effort. There is a set of rules that should be utilized for executing all operations. Sometimes compilation of these B-tree nodes fail as a consequence of which the database gets corrupted. Under such situations, MDF file gets inaccessible and need of SQL recovery software to restore database arises.

A Practical Scenario: MS SQL 2000 users come across error code 8931 that states:

“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.”

Cause: This error message is encountered due to b-tree corruption. The child page P_ID1 is not compatible with the rules of b-tree.

Unknown Database Corruption: Data Error In Cyclic Redundancy Check

SQL Server database holds importance for its administrator. What if while taking backup of your crucial database, you encounter the following mentioned error message:

10 percent processed. 20 percent processed. Msg 3271, Level 16, State 1, Line 1 A nonrecoverable I/O error occurred on file "R:\data\MyDB.mdf:"          23(Data error (cyclic redundancy check).). Msg 3013, Level 16, State 1, Line 1 BACKUP DATABASE is terminating abnormally.

When this error pop up on screen, users generally run DBCC CHECKDB command to check out the reason associated with the problem but unfortunately for this error, no reason for the issue can be discovered in error log.

Another alternative to resolve the problem that users opt is they set the database to single user mode and run the command repair_allow_data_loss via DBCC CHECKDB. But as the option itself suggests, data loss situation can arise. Therefore, it is better to rely upon SQL recovery software to fix the issue.

Data Source Name Not Found and No Default Driver Specified

Say your SQL Server and Web Server are installed on same machines. When you connect with your database from Test Server you can do it successfully but when you try to do it to the Server, you receive an error message that states:

Cause: The aforementioned error message occurs when DSN based connection is used with connectivity drivers (that works like a translation layer between the application and database management system)-ADO and ODBC in order to open database connection in ASP.

Error With SQL Server 2000 MDF File After Restart

Say while working with Microsoft SQL Server 2000 edition, your system hanged and when you restarted it, ran the application, you were unable to do so. In addition, an error message stating invalid database file pops up on screen. When you try to attach the error, again an error message like the one mentioned below is encountered:

Attach database failed for Server 'ALBORZ-PC'. (Microsoft.SqlServer.Smo) An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) The log scan number (18909:389:3) passed to log scan in database 'Holoo1_89' is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error occurred during replication, re-create the publication. Otherwise, restore from backup if the problem results in a failure during startup. Could not open new database 'Holoo1_89'. CREATE DATABASE is aborted. (Microsoft SQL Server, Error: 9003)

Cause: The reason behind this error is accidental system shutdown that leaves the database corrupted and completely inaccessible. To work around the problem, switch to proficient SQL recovery software.
