The Adaptive Server Reference Manual lists all of the reserved words for version 12. Reserved words cannot be used as object names or column names.
You must change all database names that are new reserved words before you can upgrade from an earlier release of the server. You can change table, view, and column names or use delimited identifiers. Once you upgrade to version 12, you cannot use database objects whose names are new reserved words until you modify your procedures, SQL scripts, and applications.
