Data Corruption in SQL Server and MDF Recovery

[Davidpoul]

In MS SQL Server, you use SSMS (SQL Server Management Studio) to query character data from the database which uses a non-Unicode data type. For example, the SQL Server uses the char, varchar or the text data type.

The code page of client computer differs from code page of database. In such position, the character data may be represented inaccurately. For instance, you may face any of the following issues:

The characters are represented as question mark. You may come across this matter if you have inserted or updated character data as non-Unicode data type earlier to querying character data.

The characters are represented as corrupted. The characters of one code page are stored in another code page in non-Unicode column. Furthermore, the characters are not translated.

In such situation, the MDF files get corrupted and are not accessible and might lead to the data loss.

This malfunction occurs as the characters of code page are stored in non-Unicode column of other page. In addition, the characters are not translated properly.

When using the string literal of non-Unicode data type in SQL Server, the string literal is changed by using the default code page of the database. Storing the character data of code page in a column of other code page might result into database corruption and data loss.

To stop the database corruption and work around this issue, you may try the following:

* Use binary data type
* Use appropriate collation for SQL database
* Use a Unicode data type in place of non-Unicode data type
* Use a diverse tool for storing and accessing data and disable data Translate parameter

These things will help to stop the database corruption but won’t be able to repair the corrupted database. To repair the corrupted database, you need to use SQL recovery software. With SQL recovery Software, you can repair & recover your most precious SQL database in just 2 clicks. SQL database recovery tools include advanced scanning algorithms to widely recover and restore all database components.
