Sybase IQ includes support for six external runtime environments. These include embedded SQL and ODBC applications written in C/C++, and applications written in Java, Perl, PHP, or languages such as C# and Visual Basic that are based on the Microsoft .NET Framework Common Language Runtime (CLR).
Each row in the SYSEXTERNENV system view describes the information needed to identify and launch each of the external environments. The underlying system table for this view is ISYSEXTERNENV.
The SYSEXTERNENV view is a SQL Anywhere system view. See "SYSEXTERNENV system view" in SQL Anywhere Server – SQL Reference.
