The sqlite3_create_function() call create a function that is available to the database connection used in the create call only. Your function is available in your inf program after it is created, but is no longer available after it exits. The sqlite3 command shell does not know anything about your custom function, so it can't be used there. You need to create a loadable extension module and load that into the shell for the function to be available in the shell. See http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions and the shell's .load commnad for additional info.
