Warning message after MS SQL database corruption

A warning error message while accessing the records stored in your MS SQL database occurs when the database is corrupted or there is a possibility of database being corrupted. While it is advisable not to access your data after any warning message, most of the database users tend to ignore such error messages.

But if in case, the database backup is not available or backup falls short to restore the database, then you should opt for advance third-party SQL Recovery tools that can repair your corrupted database.

Warning: Page P_ID, slot S_ID in Object O_ID Index I_ID Column COLUMN_NAME value COLUMN_VALUE is out of range for data type "DATATYPE". Update column to a legal value.

Note: Frequent occurrence of the above error message might corrupt your database to a large extent, making it totally unrepairable.
