I need to be able to duplicate via a stored procedure a specific row in the table identified by primary key value i. What is the best way to do this I have had some issues with this is there another method? Please not that other users may try and access the orginal record during this insert process. Can you give me example syntax and comments. Thank You! Woa I never see something so ugly!
