How to resolve Error 2501 in SQL Server?

A lot of users prefer using MS SQL Server as the Relational Database Management System (RDBMS) both at their home as well as their workplace. This is so because it is a robust RDBMS, which is designed to conform to the enterprises environment, organizations, and high-end users with their advanced needs. However, sometimes the SQL database file (.MDF) may get corrupted due to various reasons such as virus infections, software failure, improper shut down while database is open, etc. In such cases, you should replace corrupted database with its updated backup. However, if it is not available then you should consider taking appropriate measures to SQL Recovery Server database.

Consider a scenario wherein you are working on a SQL Server database that is the master database of your organization. You try to open one of the tables but it fails to open and gives an error message, that is:

“Could not find a table or object named '%.*ls'. Check sysobjects.”

The aforementioned error message signifies that the table has become corrupt and, therefore, you cannot access the database records.

The root cause of this error message is that the table specified in the DBCC CHECKTABLE was not found. It may have happened that the table did not exist or the metadata of the database was corrupt.

There are following measures that you can take in such situations:
First of all, make it a point to check if the table exists or not.
Replace the corrupted table with its updated backup.
Run DBCC CHECKDB without a repair clause to find out the effect of the data corruption. DBCC CHECKDB will recommend a repair clause to use. Then, use the recommended repair clause with DBCC CHECKDB.

If all the aforementioned measures are unable provide the SQL Database Recovery, then you should use a third-party MS SQL recovery tool. These read-only tools are highly interactive, and enable you to repair and recover the database components using sophisticated scanning algorithms.

SQL Recovery software enables you to repair and recover all the SQL components such as tables, rules, views, stored procedures, indexes, Defaults, Triggers, etc. In addition, it can successfully repair user defined functions and data types. It can repair the databases created in MS SQL Server 2008, 2005, 2000. It is compatible with Windows 7, Vista, 2003 Server, XP, 2000, and NT.
