Dear
We have made the payroll system in which attendance is made by scanning the card. I want to trace out those employees who enter there code by keyboard with out scaning employee card.
I am using Oracle 8.1.7 and Forms 6i.
Please Tell me How i can trace out the employees that enter employee_id by keyboard.

Thanks and Regards

This might be one way to do it: along with employee's ID, include additional identifier ("barcode scanner", id_type varchar2(2) = 'BS') to the barcode. Insert emp_id into emp_id column and 'BS' into id_type column.

So, if employee types ID using the keyboard, id_type column will be NULL.

Ok i now that this can be done by adding additional identifier in database column like "BS" for Barcode Scanner. But problem is that How i verify that Card is enter by Barcode Scanner or Keyboard. Which Trigger could distinguish between enter code by barcode scanner or enter code by keyboard. Please tell me in detail.
Thanks for reply

No trigger. Barcode should have that information in it (and insert 'BS' into an item which is not accessible by keyboard).

My dear you are looking in the wrong place. Your attendance machine should be having a software/interface of its own. Check there. Normally the data has a readtype which lets you know how the record has been authenticated. Use that. For oracle, unless you have this field, the data is going to be alike.
