SQL Database management system is used to store important database files in form relation, tables, views and indexes in an organized manner. It consists of system catalog containing meta data which means set of data. As the system catalogs comprised of names, names of tables, views and indexes. But due to some reasons such as virus infection, hardware issues, power outages,default storage size limit cross over, coming under suspect mode, forcefully shutdown of system, application crash, modification in SQL queries etc, the meta data structure gets corrupted or damaged and you are not able to access your important database files. Due to this, SQL users come across several types of database errors like as SQL Error 7995, SQL error 8946, SQL error 5235 and SQL error 8930 etc and many more. Let us discuss about all these errors in detail.

- The system base table storing the meta data for all the objects in the database.
- The system base table are corrupted.
- The hardware malfunction in the disk system.
- Instant power failure in the middle of the any process.
- Duplication of database leads to the loss of data. It also happens by creating triggers on system tables.
- When you are trying to rename the primary file group, it will not change but yes it can causes errors to be generated.
How to Fix SQL Error 7995 ?
In order to get overcome from the problem, you need to recover the .MDF file and for repairing the file, you have to perform the given below SQL Repair methods:-

2. Restore from backup:- If it is not because of hardware issue, then check for backup of the database and if it is clean and updated, replace it with backup.
3. Run DBCC CHECKDB:- if you do not having the clean backup, then you should run DBSS CHECKDB command without any repair clause to know the level of corruption and after that again run with suggested repair clause.
Aforementioned method is used to recover the database file. But there are very less chances of recovery using this method. Therefore, in such cases you can use third party called SQL Database Repair Software which is fast and sophisticated way to get the recovery of database file.
