“Read this blog engagingly to know how to repair corrupted SQL Server transaction log files by executing some workable SQL commands and get back access to your SQL database files once again.”
MS SQL Server, the most commonly used database server, is vulnerable to corruption due to various logical and physical reasons. Let us suppose a situation when you are informed that one of the transaction log files has been corrupt due to some unknown reasons. Because of the transaction log file damage, SQL Server finds it difficult to access the required .mdf file.
It means .mdf file requires recovery, which can be easily done with the backup of MDF file you have. However, in case you do not have a backup of the MDF file, SP_ATTACH_DB_SINGLE_FILE_DB command can be a help for you. The command helps you rebuild the database but only in the following two ways:
Use the SP_ATTACH_DB_SINGLE_FILE_DB command on the MDF file that was previously detached from the server through SP_DETACH_DB command.
Use the SP_ATTACH_DB_SINGLE_FILE_DB command on the MDF file having only one log file.
In case, you do not have any backup of the MDF file and also the SP_ATTACH_DB_SINGLE_FILE_DB command does not help you rebuild the database then execute the following steps (on your own risk) to restore the database:
Note: The above-mentioned steps are very tricky and could result in data loss. It is recommended that users should perform them in a test environment at their own risk.
The executed steps will repair the damaged MDF file and you will be able to work with it. However, in case these steps do not work, you need to take the help of MDF recovery and repair software. SQL Recovery is well designed and easy-to-use SQL Server data recovery tool. The software recovers database objects like: tables, triggers, rules, functions, deleted records etc. from damaged MDF files created in any SQL Server version. One can recovered data to a live SQL Server or bath file after previewing it.
Let us know the working of the software through these steps:
Thus, recovering data from the corrupt SQL database is an easy affair for Kernel for SQL Database Recovery software. It recovers all database objects quite smoothly.
We have discussed a situation where a transaction log file of the SQL Database gets corrupted. For recovery, manual solutions like the use of backup (if available) and rebuilding of the database to restore the database (if backup not available) are explained. Also, recovery through a third-party tool is explained through screenshots.
