Five stars for me as I find this type of article almost a "reverse engineering" concept, sometimes this can help with the understanding.

Good stuff.

SQL 2K acts like a spoilt child - you need to coax it round with lollipops.

mY database will be corrupted [font="Arial"][/font].so how to recovery the corrupt database??????( i have little bit confusing.because of iam using below script reocvery the database :

DBCC CHECKDB ('Corrupt2K8') WITH NO_INFOMSGS, ALL_ERRORMSGS
exec sp_resetstatus 'Corrupt2K8'
alter database Corrupt2K8 set emergency
dbcc checkdb('Corrupt2K8')
alter database Corrupt2K8 set single_user with rollback immediate
dbcc checkdb('Corrupt2K8', REPAIR_ALLOW_DATA_LOSS)
alter database Corrupt2K8 set multi_user ))

NOTE: some points for consideration:

Then restore My database from a backup - but make sure to run DBCC CHECKDB on that very backup to ensure it's not corrupt itself.

DBCC CHECKDB with REPAIR_ALLOW_DATA_LOSS is the very last resort . Before that, you should restore a valid backup. Once you do use REPAIR_ALLOW_DATA_LOSS, don't expect your database to magically come back to life again - most likely, irreparable damage has occurred - especially in this case since it complains about system table corruption.

Thank you in advance
