: : Is there a way to prevent duplicate records in Delphi while using tables? Thanks for your help :)
: function FindKey(const KeyValues: array of const): Boolean; (success = true)
: Use this to check whether or not the key(s) already exist. Obviously if it does then its gonna be a duplicate record (do this before post).
Out of interest TDataset generates exception EKeyViolation when theres a duplicate key.
