I have SQL developer of version 21.2 and PL/SQL developer of version 7.1.5
A simple query to replace special characters isn't working for a table.
Ex:
SELECT translate('à with a and è with e', 'àè', 'ae') FROM table;
or regexp_replace r even simple replace.
If i do same replace in dual table it works fine. Could there be issue in that particular table data?
