| I have a table with several fields. I would like to ensure that that each triple combination from the three first fields is unique.In other words, instead of ensuring unicity based on a single field, I would like to ensure unicity on a triple of fields (equality being defined as a field-wise equality for each one of the three fields).How can I achieve that?Thanks in advance,Joannes |
