I'm trying to search in my name field for the records with no alphanumeric values.
I want to find the records with only null value or only special characters such as . , ? ! * % #.
1 James Brown??..
5 1/James Brown***
Then, I want my code to return only ID 2,3,4 and not 1,5.
Also, I need to put this check in a case statement, rather than in a where clause.
Can you please help me how I can write this check using regexp_like or regexp_replace?
