First, even though it may or may not apply in this instance, it is ALWAYS a good idea (and good manners) to provide the PostgreSQL version and your O/S when posting to this board.
I have also previously replied that the following should work:
UPDATE pcilms_assign SET intro = REPLACE (intro, 'HVACR1114_LAB_13A.pdf', '&file=HVACR1114_LAB_13A.pdf') WHERE intro like 'https://owncloud.porterchester.edu%' AND course=18 and id=55413;
NOTE: DO NOT use % in front of 'https: It is not needed and will slow query performance.
Your mileage may vary because you have not stated your VERSION of PostgreSQL or your O/S.

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.
Need the final string to separate the "LAB_13A.pdf" from the rest of the URL by inserting a "&file=" in front of it. The final string should look like:
update pcilms_assign set intro=regexp_replace(intro, '/([^/]*)\" title=$', '&files=\1') where intro like '%https://owncloud.porterchester.edu%' and course=18 and id=55413;
and the result puts the &file= in the wrong place (at the end of the whole string).
Any suggestions?
Thanks!
-Chris
