regex - pig: how can I extract a tuple with all characters in a chararray?

Question

I have a tuple with my_string = '12345', I want to turn it into this tuple: ('1','2','3','4','5').

Tried: REGEX_EXTRACT_ALL(my_string, '(.)') and got only (1).

Answer 1

Replace を使用して (1,2,3,4,5,6) に変換します。

REPLACE(my_string,'(?<!^)(.)',',$1');
