MS SQL Server, the fastest and the most valuable database management system specifically suited the most in an enterprise environment. In fact, this SQL Server has become an indispensable application today that facilitates a lot of work in any organization. This amazingly advanced application helps users to effectively manage the enterprise data in the shape of tables. Whenever a user needs to access any data information stored in these tables, he needs to run queries for fetching the information he desires. But, sometimes trouble strikes when SQL stops working and then comes the role of restoring SQL server database.
Some reasons for this SQL corruption can be:
• Unexpected application shutdown
• Application errors
• Hardware bugs
These and other such flaws can lead to DBCC CHECKDB errors which in turn can cause table data inaccessibility. Every users wants this crucial data back and he also wants to resume SQL Server to work again properly and so the software for repairing MDF have become so much commonly used tools.
Issues with the table results in the display of the following error message:
Server: Msg 8942, Level 16, State 1
Table error: Object ID O_ID, index ID I_ID, page P_ID. Test (TEST) failed. Slot S_ID, offset 0xADDRESS overlaps with the prior row.
The reason for such error is basically the overlapping of slots. The table structure of SQL database happens slot by slot which has a specific id. What happens in normal situation is that the next slot has to be greater than the previous slot because it manages the slot in an ascending order. Whenever there is table test it means it reads SQL table structure so the table slots should be in that order only which is the normal order. But, due to some unavoidable reason, this becomes order less; previous slot id greater than that of the next slot which leads to an error which is generated in the next slot. An error will be generated that the id of a particular slot is greater than its next slot which should not happen because it would break the ascending order of the table structure. In such a scenario it becomes imperative to fix SQL 8942 error and thus fix SQL 2005, 2000 Server and more.
What can be done?
In such a problem situation, the user can,
• Try to restore database from the latest data backup. But if it is unavailable then you can either try the below methods or go for an outside SQL database 8942 error fix tool.
• There is a possibility of some hardware issues causing such error. So, the user has to diagnose the system, the application and the SQL Server error logs in order to know the actual issue. If there is any such issue found, then the user can replace the damaged hardware with a fresh functioning hardware.
• In the case, where no hardware issue shows up, then user can run DBCC CHECKDB command but without using any of the repair clause. This command determines the repair clause that needs to be applied for the solving of this error. When the repair clause is attained, then one can run DBCC CHECKDB with the correct repair clause.
After the user applies any of the above given methods, there is a chance of data loss. But, still one need not panic. Because, lost data can be retrieved and recovered by a software tool for fixing MDF. But, an apt and right software will only be the data savior. SysTools SQL recovery tool will fix SQL 2000, 2005 etc successfully without any undesired extra effort on the part of the user in learning, understanding and using the software. Also, result is 100%. The tool will not let you down; it will ensure successful completion of the SQL repair process.
