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The SYSIXCOL system table has been replaced by the ISYSIDXCOL system table, and its corresponding SYSIDXCOL system view.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