I'm trying to write a SQL script without create a new column to storage footnote. How can I separate data based on letter a, b, c, and d:

columnA  footnote
0.0002a      a
0.3b            b
000c           c
0.333      
0.343d        d
....

I know this script is incorrect, but you get an idea what I'm trying to do:

Select columnA, rtrim(columnA, 1) as footnote from table

Thanks,

If you have more than letter or string of letters:

select regexp_substr(columnA,'[a-z]+$') from tab1;
