In maintenance plan wizard, if you choose check database integrity and repair minor errors, the wizard will create a job for it, the command will be :
dbcc checkdb(<db>, REPAIR_FAST) WITH NO_INFOMSGS
Run this command need to be in single user mode. So this job will always fail.
It seems incredible that the maintenence plan wizard can generate a job like this, I think I must be wrong somewhere, can somebody point me to the right direction?
