As a pathologist, I have a database that keeps records of cases back to 1993. The pathology accession numbers before January 1, 2000 were "S followed by the two digit year number followed by a dash then the case number for that year (example S99-3579). With the new year we switched to a four digit year format (i.e. S2000-0001), but as the key field in this table, sorting in ascending order puts the 2000 cases first and will continue to insert all new cases before the first 1993 cases. There may be more obvious ways around this but I thought if I inserted "19" into all S9X-XXXX entries then the order would again be correct. Thanks for your help in advance.
