你可以试试这个

        and (tbc.Mobileno=IFNULL(CallerID,tbc.MobileNo) or (CallerID = null tbc.Mobileno =null))

    and ( tbc.Booking_reference=IFNULL(book_ref, tbc.Booking_reference) or (book_ref=null  tbc.Booking_reference = null))

    and ( td.VehicleRegistrationNo=IFNULL(vehicle_number, td.VehicleRegistrationNo) or ( vehicle_number =null  td.VehicleRegistrationNo = null))

and ( td.FirstName=IFNULL(vehicle_Driver, td.FirstName) or ( vehicle_Driver = null  td.FirstName = null))

and ( (PartnerType='Android Booking' and tbc.DeviceType='ANDROID')  

or ( PartnerType='Web Booking' and tbc.DeviceType='WEB')

or ( PartnerType='Call Center Booking' and tbc.DeviceType='0')

or ( PartnerType='All Booking' and 1=1 )
