[GENERAL] Regex help again (sorry, I am bad at these)
Hello all! Sorry to have to ask the experts here for some regex assistance again. I am admittadly awful with these and could use some help. Have the following string (this is an example) that needs to be changed. Need to use a search and replace because the links across over 200K records are similar but not the same. 'Complete the attached lab and submit via dropbox\rhttps://owncloud.porterchester.edu/HVACR/PCI_GasHeat/GasElectrical/HVACR1114_LAB_13A.pdf; title="Lab 13A">Lab 13A<\a>' Need the final string to separate the "LAB_13A.pdf" from the rest of the URL by inserting a "=" in front of it. The final string should look like: 'Complete the attached lab and submit via dropbox\rhttps://owncloud.porterchester.edu/HVACR/PCI_GasHeat/GasElectrical/=HVACR1114_LAB_13A.pdf; title="Lab 13A">Lab 13A<\a>' I have tried something like: update pcilms_assign set intro=regexp_replace(intro, '/([^/]*)\" title=$', '=\1') where intro like '%https://owncloud.porterchester.edu%' and course=18 and id=55413; and the result puts the = in the wrong place (at the end of the whole string). Any suggestions? Thanks! -Chris

[GENERAL] regexp_replace question / help 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 "=" while preserving the filename and
extension following the "/".
The closest I can get is:
regexp_replace('http://test.com/test/testfile.php','/[^/]*$','=')
however this looses the file name and returns:
http://test.com/test=
What I am looking for is:
http://test.com/test=testfile.php
as a result.
Would anyone here point me in the right direction?
Thanks!
-Chris
