Ed Barlow created
the sp__monunusedindex stored procedure for displaying the indexes that have not been used since server start in Sybase ASE as part of the excellent Extended Stored Procedures by Ed Barlow (AKA the Ed Barlow Stored Procedures).
I’ve updated the stored procedure to include the table owner and all the indexes & index keys. I’ve also fixed the formatting of the data.
