Hi all,

I am trying to create a unique identifier for each row, combining numbers from three columns.

Do you know if there is a general formula to do this (or some manual where I can read about this)?

I figure I can use the numeric entries of the columns as "coordinates" and multiply them with different coefficients (different magnitudes) to get the unique ID - but it would be nice to read about such algorithms in general.

Any links/input would be great -

Ralph
