SQL Anywhere includes support for six external runtime environments. These include embedded SQL and ODBC applications written in C/C++, as well as applications written in Java, Perl, PHP, or languages such as C# and Visual Basic that are based on Microsoft's Common Language Runtime (CLR).
Each row in the SYSEXTERNENVOBJECT system view describes the installable external environment objects. The underlying system table for this view is ISYSEXTERNENVOBJECT.
