Summary : Executing DBCC DBREINDEX and DBCC SHRINKDATABASE simultaneously in SQL Server can corrupt table structure, leading to data loss. To prevent this, schedule operations separately, disable auto shrink, and use recovery methods like DBCC CHECKDB or specialized tools such as Kernel for SQL Database for efficient, data-integrity-preserving repairs.

The Database Administrator has the authority to execute various commands on the tables within created databases. Typically, these commands are run sequentially to maintain the table’s structure and integrity. However, if two different types of commands are simultaneously executed on a single table, it can significantly impact the table’s structure and potentially lead to data deletion or corruption.

DBCC DBREINDEX is a transactional SQL command designed to reconstruct one or more indexes for a table within the SQL database file. Conversely, DBCC SHRINKDATABASE, another T-SQL command, is employed to reduce the size of data and log files within a specific database. However, if both these commands are executed simultaneously on a particular table, it can lead to corruption. In instances of corruption without backup, users can restore the table using reliable SQL recovery software.

Therefore, if a user attempts to execute DBCC DBREINDEX simultaneously with DBCC SHRINKDATABASE on a table, they will encounter the error message stated below:

Table Corrupt: Object ID 0, index ID 0, page ID (1:623). PageId in the page header = (0:0).

Reason behind the issue – The error message mentioned above halts the entire shrinking operation, leading to table corruption. This corruption occurs when the user tries to execute both the shrink database and re-indexing operations simultaneously.

Solution – To avoid encountering this issue in SQL, users should reschedule their operations, executing them at separate times while disabling the auto shrink option. Furthermore, to address the aforementioned error, users must utilize the DBCC CHECKDB command with the repair_allow_data_loss option. However, even after running the command, there is a possibility that the error might be inaccurately reported as fixed. In such cases, it is advisable for the user to restore the table from the most recent backup. If no backup is available, efficient SQL server recovery procedures should be performed.

SQL Recovery Software this Microsoft SQL Server recovery software is highly efficient and meticulously designed to facilitate seamless SQL database recovery. Its intricate development enables it to repair and restore various SQL components such as tables, queries, views, triggers, and stored procedures, utilizing powerful scanning methods. The software ensures secure and non-destructive SQL database recovery, boasting an interactive user interface that simplifies the entire process, making it easy to comprehend and execute.

The SQL repair software excels in recovering crucial data from MS SQL Server and is compatible with a wide range of versions, including MS SQL Server 2019, 2017, 2016, 2014, 2012, 2008 R2, 2008, 2005, and MS SQL Server 2000. Additionally, it seamlessly operates on various Windows platforms, including Windows 11, 10, 8.1, 8, 7, Vista, XP, 2003, and 2000.

Conclusion

In the event of database corruption, it’s imperative not to delay action, as waiting can allow the corruption to spread and potentially impact other tables within the database that share relationships with the affected one.In the event of database corruption, it’s imperative not to delay action, as waiting can allow the corruption to spread and potentially impact other tables within the database that share relationships with the affected one. Kernel for SQL Database software is capable of repairing the entire database within the MDF file, recovering every item stored in each cell. It ensures the preservation of dependencies and relationships as well.
