Thread: regexp_replace question/suggestions needed
Could you not use a simple capture and a greedy * ...
Should deal with your example
select regexp_replace('http://test.com/test/testfile.php','(.*)/(.*)','\1&file=\2');
and as requested <with different length and number of components>
select regexp_replace('http://test.com/otherstuff/in/path/test/testfile.php','(.*)/(.*)','\1&file=\2');

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','/[^/]*$','&file=')however this looses the file name and returns:What I am looking for is:as a result.Would anyone here point me in the right direction?Thanks!-Chris
Not the most elegant, but this seems to do the trick
# select regexp_replace('http://test.com/test/testfile.php','/[^/]*$','') || '&file=' || regexp_replace('http://test.com/test/testfile.php','.*/','') ;
?column?
