Extract string items into rows?

Post by debfawn » Tue Mar 07, 2017 7:42 pm

Hi all,

Anyone know how I can convert a comma separated string of items into rows? So if I have a string like A,B,C,D I want to have 4 rows, one with A, one with B, one with C and finally, one with D. Is that possible?

Thank you

Here is one way:

dbadmin=> select split_part('A,B,C,D', ',', rn) split_into_rows from dual
dbadmin-> cross join (select row_number() over () rn from columns) foo
dbadmin-> where rn <= regexp_count('A,B,C,D', ',')+1;
split_into_rows
-----------------
A
B
C
D
(4 rows)
