This function automatically drops the SQL Type wrappers based on the CLR Reflection API. If there is compiled Virtuoso/PL code that references the type it will fail to execute (with a compilation error) when executed or compiled.
Now this library must be introduced to the Virtuoso Server. In ISQL use the following commands to test the CLR:
SQL> DB..unimport_clr (vector ('sanity'), vector ('sanity')); Done. -- 300 msec. SQL> select sanity::test('Rob'); *** Error 37000: [Virtuoso Driver][Virtuoso Server]UD041: No user defined type DB.DBA.sanity at line 2 of Top-Level: select sanity::test('Rob')
