UPDATE your_table SET your_column = REPLACE (your_column, 'HVACR1114_LAB_13A.pdf', '&file=HVACR1114_LAB_13A.pdf') WHERE <whatever_expression is needed>;
Your mileage may vary because you have not stated your VERSION of PostgreSQL or your O/S.
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
