How to get the last index of a substring in SQLite?

Question

I have a string in the table: http://www.foo.com/hello/bar/baz and I want to get everything that comes after the last \'/\' (in this case the string \'baz\'). <

Answer 1

There are limits to sqlite core functions' expressive power. For a known maximum number of / characters, this can be accomplished by a series of nested substr() and instr() calls, removing parts of the string to the next / at a time, but that's not too elegant.

You should really do it in your programming language instead.
