tar can't interpret patterns for include
Your first command 
        tar czf foobar.tar.gz *.sql
works, because *.sql is expanded by your shell to "foobar.sql", immediately 
_before_ starting tar.

With:
        tar -C ~/foobar -czf foobar.tar.gz *.sql
the shell can't expand "*.sql", because there is no file on current dir (before 
starting tar). So it's not expanded and given to tar.
Then tar starts, changes to "~/foobar" and finds no file '*.sql' (as literal 
name, not as a pattern!!!) - error message is thrown.

Tar can't interprete patterns for include.

There are some solutions to create a file list and give it to tar. 
I would find one, but it will be never perfect, and may be work only to the 
shell, I prefer.

Try to find "tar include" at the web ...
