In python, it is easy.
>>> def foobar(): print 'hello world'
...
>>> exec('foobar'+'()')
hello world
>>>
However, the exec() might be considered dangerous if you are not sure
what function name string would be inside DB. So if I were you, I
would still use a translation system, but a more elegant one (I
think):
def foo(): print 'foo'
def bar(): print 'bar'
dispatcher={
'foo': foo,
'bar': bar,
}
def oops(): print "oops, I don't know that name"
dispatcher.get(func_name_str, oops) ()
