The B-trees in the database systems are the data structure that help in storing data in sorted order. As the data is stored in the sorted order, you can easily perform certain database tasks such as adding new records, deleting existing records, searching and retrieving data with lesser turnaround time. These b-trees have certain rules laid out using which all the operations are performed. At times, some nodes in the tree fail to comply with them because of database corruption, thereby damaging the database. In such cases, you should use the in-house methods to repair MDF file, failing which you should resort to using third-party sql repair
software to do the needful.
Let us consider a situation in which you are getting the following error message while working on the MS SQL Server 2000 database:
“Table error: Object ID O_ID, index ID I_ID B-tree level mismatch, page P_ID1. Level LEVEL1 does not match level LEVEL2 from parent P_ID2.”...

Database corruption in SQL databases can amount to huge losses depending upon the size of your organization. Because of database corruption, you would not be able to access the databases, work on them, and most importantly all the stored records would become vulnerable. But there are certain in-house workarounds that would enable you to perform mdf recovery. However, if these methods do not work then you should use a third-party sql database recovery
software to repair the damaged database.
Consider a situation in which you are facing the following error message while working on an MS SQL Server 2000 database:
“Table error: Object ID O_ID, index ID I_ID, page P_ID, row S_ID. Test (TEST) failed. Values are VAL1 and VAL2.”
The most prominent reason for this table error is that the a record has failed while auditing as corruption is detected in its record header.
