A few days ago, the database file has a problem, and the phenomenon is that some query operations will report the following errors:
Microsoft OLE DB Provider for SQL Server Error '80004005' Warning: Fatal Error 644 Occurred At Aug 5 2004 8:45 AM
or:
Microsoft OLE DB Provider for SQL Server Error '80004005' Warning: Fatal Error 823 Occurred At Aug 4 2004 10:39 PM
823 Error means that SQL Server encounters I / O errors when reading or writing a request for a device. This error usually shows disk
problem.
644 Error refers to: This error occurs when the index ID represents the non-aggregated index. This corruption is detected when the process attempts to delete the unsausty.
The hard disk of that database server is to do RAID 5, query the specific hard drive, and did not see the hard drive. Back up the data and return to another machine. There is still this problem. Obviously the database file has a bad block.
Try to fix the database by the following statement, but only some data can be repaired, but it cannot be completely fixed.
DBCC Checktable ('Data Table') DBCC CheckTable ('Data Table') with all_errormsgsdbcc checktable (data table, repair_allow_data_loss)
DBCC DBREINDEX ('Data Table ")
Sp_dboption 'Database Name', 'Single User', Truedbcc Checkdb ('Database Name, Repair_Allow_Data_loss) sp_dboption' Database Name ',' Single User ', False
The import function with SQL Server cannot export data. The 823 error will be reported. The select of all data will also report 823 errors.
Below is some representative error messages returned after returning by these fixing statements:
