>>Hi,

>>Say I have a table that has column MY_INT_FLD I(4). There could be some records in this table that have the same value in this field. And some records that have 0 in this field. I want to create one or two (or maybe even three) UPDATE command(s) that will set each record of this table to a unique value and it has to be greater than 0. Is it possible? TIA.

Thank you. The goal was not just to have a unique value (what Sergey suggested would have done it). But the goal was to preserve all the existing values and only change the value in records where duplicate exists.
