I have a table with one column containing file paths, such as /path/to/file and

make the changes in PHP and rewrite the rows, but I wondered if there was a 
clever way to do it all in SQLite in, essentially, one statement. A quick look 
persuades me there are not enough functions built into SQLite for that, but 
confirmation would be handy.

update mytable set path='/path/from/' || substr(path, length('/path/to/') + 1)
where substr(path, 1, length('/path/to/')) = '/path/to/';
