Recover SQL database when tables become inaccessible

MS SQL is most widely used database application among various organizations all over the world. Due to its useful data management and maintenance facilities, this application comes as a boon to the enterprise users. SQL database consists of various tables which are groups of specified number of rows and columns containing major chunk of records. A DBA can fetch any record from any table as per the requirements and store data into the table by running a query. The database is useful as long as it displays desirable results as per the query generated by the users. When it starts showing various wrong results and error messages then it is predicted that database corruption has occurred. An error message prompts on the screen while posting queries on a corrupted or damaged SQL database.

SQL corruption can happen due to the following reasons:

• Sudden shutdown of system that can happen due to power failure
• Exceeded database file size limit
• Invalid database file header
• Emptied disk space while database working
• Defects in main memory, hard drive, cache, server and raid controllers
• Internal program error
• Media damage
• Copying of some file while the server is running

Due to the above cases, corruption in the SQL database is occurred causing exclusive data loss for the users. Consider a real time scenario where a user wants to count the number of rows of table and he executes count(*) query. But, the result of the query displays the following error message instead of providing total number of rows

“Attempt to fetch logical page (1:42724) in database ‘test’ belongs to object ‘report-table’, not to object ‘RRR’. Connection Broken..”

To get rid of the above situation, you must have to follow up a recovery mechanism which repairs SQL database. Using third party software gives the best result among all other possible solutions. SQL repair is such a tool that provides efficient recovery mechanism to repair corruption issues involved in SQL database files.
