MS SQL Server, being a relational database management system (RDBMS) is a storehouse of huge amount of data and to manage it efficiently, paging technique is used. With the help of this technique, the large chunks of data are splitted into logical as well as manageable pages. The pages are arranged sequentially and can be retrieved easily by moving forward and backward.
However, these pages within the database table sometimes turn inaccessible due to the common reasons of corruption such as human errors, abrupt system shutdown, virus attack, power failure, etc. Let us go through a real life scenario where you want to retrieve the database table in MS SQL server 2000. When you run DBCC command, instead of the result the following error message pops up:
"Table error: Object ID O_ID, index ID I_ID, page ID P_ID1. The PageId in the page header = P_ID2."
Most obvious reason for occurrence of such an error is that upon receiving the command when the server searches for the header of the requested page, it is found in another page. Other possible reason is corruption of database table. However, once the error message is encountered an appropriate solution for it should be looked for.
First of all, run a DBCC CHECKDB command in order to know that the table has been corrupted to what extent. After that, run the command again along with repair clause. Secondly, you can ensure that the hardware components are working fine. By running the hardware diagnostics, go through the error log file and check if error has occurred due to any hardware component failure. Yet another solution is to restore the entire database with an updated backup if you have maintained one. In case, the aforementioned solutions do not work out for you then the simplest one is using a commercial SQL recovery software.
