Follow the below code:

SQL

update atten set atten.Att_UpdateBit='0' from Attendence atten
 join EmployeeMaster Emp on (Emp.@ATReprs_Location=atten.fk_Emp_LocCode or Emp.@ATReprs_Location='All')  and
 (atten.fk_Emp_CatCode=Emp.@ATReprs_Catagory  or Emp.@ATReprs_Catagory='All')
 and(atten.fk_Emp_DepCode=Emp.@ATReprs_Department or  Emp.@ATReprs_Department='All')
 where  Att_Date>'some date'
