Regexp_replace question/assistance needed

Hello,

I am running into a problem and need some pointers on regexp_replace - I can't seem to find an answer in any of the online resources.

I have a string (like 40,000 with different length and number of components) of them in a field named "externalurl". I need to replace the final "/" of the string with "&file=" while preserving the filename and extension following the "/".

The closest I can get is:

regexp_replace('http://test.com/test/testfile.php','/[^/]*$','&file=') 

however this looses the file name and returns:


What I am looking for is:


as a result.

Would anyone here point me in the right direction?

Thanks!
-Chris

select 
overlay ('http://test.com/test/testfile.php' placing '&file=' from
for 1)

of course you would use a variable instead of a string literal
