Index Corruption May Damaged Microsoft SQL Server Database

Are you getting index corruption errors in SQL Server 2000 database while running DBCC CHECKDB statement? Index is a data structure in SQL Server database, which improves the performance of database operations. SQL Server uses indexes for accessing data from the MDF (Master Database File) database. In case of corruption, SQL Server may not locate and access the data or even the database itself may get damaged. It leads to critical data loss situations and needs SQL Database Recovery to be fixed.

In a practical scenario, you may come across the below error messages when you run DBCC CHECKDB statement on a MDF database that is upgraded to MS SQL Server 2000 from an earlier version:

Server: Msg 8951, Level 16, State 1, Line 1
Table error: Table '' (ID ). Missing or invalid key in index '' (ID ) for the row:
Server: Msg 8955, Level 16, State 1, Line 1 Data row (1:133:42) identified by (RID = (1:133:42) ) has index values ( = 0).
Server: Msg 8952, Level 16, State 1,
Line 1 Table error: Database '', index '.' (ID ) (index ID ). Extra or invalid key for the keys:
Server: Msg 8956, Level 16, State 1, Line 1
Index row (1:137:0) with values ( = 0) points to the data row identified by (RID = (1:133:42)).

After the above errors, you cannot check the integrity and consistency of the database and it remains in inconsistent state. In order to gain access of your database in such cases, you need to find out the cause of this behavior and perform SQL Server Recovery by fixing it.

Root of the issue

In earlier versions of SQL Server, like SQL Server 7.0, if sysindexes.status value is set to 0 for nonclustered index in table, nonclustered index also enables insertion of the NULL values. When you run DBCC CHECKDB statement on database of SQL Server 7.0, you do not encounter such problem. After upgrading to SQL Server 2000, DBCC CHECKDB statement displays the above error messages because the NULL values isn't allowed when sysindexes.status value isn't 2097152.

This problem may also occur if the MDF file is damaged due to virus infection, improper system shutdown, or other similar reasons.

To sort out such issues, MS SQL Recovery is essential. It is possible through powerful and advanced third party SQL Recovery software. They enable safe, easy, and quick recovery of your valuable data.

SQL Recovery restores all MDF file objects such as tables, reports, forms, triggers, stored procedures, and constraints. The software works well with MS SQL Server 2008, 2005, and 2000.

The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood. However, there are a new set of challenges for IoT devices that generate megabytes or gigabytes of data per second. Certainly, the infrastructure will have to change, as those volumes of data will likely overwhelm the available bandwidth for aggregating the data into a central repository. Ochandarena discusses a whole new way to think about your next...
Cell networks have the advantage of long-range communications, reaching an estimated 90% of the world. But cell networks such as 2G, 3G and LTE consume lots of power and were designed for connecting people. They are not optimized for low- or battery-powered devices or for IoT applications with infrequently transmitted data. Cell IoT modules that support narrow-band IoT and 4G cell networks will enable cell connectivity, device management, and app enablement for low-power wide-area network IoT. B...

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
