Hi gurus,



I have a employee table, when an employee firstly input into the
system, he/she does not have Emp_Number yet, after some approval
process only then Emp_Number is generated.



Question is : since Emp_Number can be null at first, should I have PK
on this table ? or just Unique Index ?



Thank you,


xtanto
