Discussing text node corruption in SQL Server 2000 and the possible resolution measures

-->

MS SQL Server is embedded with a number of enhanced, powerful features to make it easy to hold and manage the data of the largest websites and IT projects. It has integrated XML support and a highly efficient programming model for developing web applications. Its database engine can be used on a variety of platforms. It embraces various advanced tools to extract and analyze data, design databases, and other useful tasks. However, an SQL database is prone to corruption due to many reasons. A few critical causes leading to database corruption include virus infection, hardware issues, abnormal system shutdown, etc. As a consequence, all your valuable database components become inaccessible. To overcome this problem, you need to go for MS SQL recovery software through a reliable third-party utility.

For instance, while working with one of your important databases created in MS SQL Server 2000, you may come across the following error message:

“Table error: Object ID O_ID. The text, ntext, or image node at page P_ID1, slot S_ID1, text ID TEXT_ID does not match its reference from page P_ID2, slot S_ID2.”

Cause: The above error occurred because there is corruption in a particular text object. The text object contains a child node that does not match its parent node. The text data nodes in an object are the one that are present at the leaves and store actual data. The text index nodes occupy the next higher levels in the B-tree structure.

Anyone of the following reasons might have resulted in the above error message:

• The timestamp in the node is not the same as found in its parent.
• If the node is a text data node, its size is greater than or equal to the one as assumed by its parent.
• If the node is text index, its size does not matches what its parent thinks it should be.

Resolution: You may try any of the following methods to resolve the issue-

• Use a recent/updated backup to restore the complete SQL database.
• To fix logical corruption, use DBCC CHECKDB with appropriate repair options.

If the problem still persists, take help of an efficient SQL database recovery utility. These third-party software provide a smart and effective means to safely repair corrupt SQL databases and recover valuable database objects with all their original properties and relationships intact.
