Back in 2006, Mich Talebzadeh created
the sp__monusedtables stored procedure for reporting on table usage in Sybase ASE 12.5x using the MDA tables as part of the excellent Extended Stored Procedures by Ed Barlow (AKA the Ed Barlow Stored Procedures). In v15, Sybase deprecated the rowcnt() function that was used to report on the estimated number of rows in favor of the row_count() function. I’ve updated the stored procedure to use the row_count() function.
