Common Errors in MS SQL

Error message in MS SQL Server database can occur at any time, such as, while mounting the database, closing the database, and while accessing the records saved in the database. While the reasons for the error message differs from situation to situation, the most common cause remains is corruption of MS SQL Server database. To overcome this error message, an effective way is to run an inbuilt repair command known as DBCC CHKDB with an appropriate repair clause. This command checks and repairs corrupted SQL Server databases in most situations. But, there are many cases where the user still encounters corruption errors even after running this command. Such cases occur when the database is severely corrupted.

Some of the such error messages are discussed below:
