The SYSTABLE view is provided for compatibility with older versions of Sybase IQ that offered a SYSTABLE system table.
The SYSTABLE system table has been replaced by the ISYSTAB system table, and its corresponding SYSTAB system view.
The SYSTABLE view is a SQL Anywhere compatibility view. See SQL Anywhere 11.0.1 > SQL Anywhere Server - SQL Reference > System Objects > Views > Compatibility views > SYSTABLE compatibility view (deprecated).
