In ODBC 3.0, SQLFreeEnv() has
been deprecated and replaced with SQLFreeHandle().
Although this version of CLI continues
to support SQLFreeEnv(), use SQLFreeHandle() in
your CLI programs
so that they conform to the latest standards.
Migrating to the new function
The statement:
SQLFreeEnv(henv);
for example, would be
rewritten using the new function as:
SQLFreeHandle(SQL_HANDLE_ENV, henv);
