Logical page error while attempting to insert data I am getting the following error while trying to insert a row in a table:


  Attempt to fetch logical page (1:12032) in database 19 failed. It
  belongs to allocation unit 72057594069450752 not to 72057594051166208.


What could be the reason?
I think you have a database corruption so try the command 

DBCC CHECKDB


And The command 

 dbcc checktable ( 'dbo.TableName', REPAIR_REBUILD )


Before that Refer to BOL to see about the commands .
