Hi again, and thanks for sticking with this.

Ok.
CREATE TABLE test(x TEXT);
INSERT INTO test VALUES ('abc');
SELECT REGEXP_REPLACE(x, '<something>', '<something_else>', 'g') FROM test;
Expected result: ABC

David Johnston suggested something along these lines:

But it's a bit above my pay grade to do this - I've tried, but no go! :-( It
*_appears_* to me that the string's length would have to be hard coded under
this strategy - but if that's the only way, then so be it.
I'd just be interested to see a solution based on DJ's suggestion or any other
code that would use REGEXP_REPLACE() to do what I want - preferably without
hard coding, but if it's absolutely necessary.
Thanks for any input.
