Chris, 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: <https://owncloud.porterchester.edu> 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.

Whether or not you wish to share my fantasy is entirely up to you.
