select values from t
values
a,b,c,d
但是我想要的结果是,请高人指点，tks！
values
a
b
c
d
------解决方案--------------------
- SQL code
with test as( select 'aaa' a,'1,2,3' c from dual union all select 'bbb' a,'1,2' c from dual) select a,substr(t.ca,instr(t.ca, ',', 1, c.lv) + 1,instr(t.ca, ',', 1, c.lv + 1) -(instr(t.ca, ',', 1, c.lv) + 1)) AS cfrom (select a,',' || c || ',' AS ca,length(c || ',') - nvl(length(REPLACE(c, ',')), 0) AS cnt FROM test)t, (select LEVEL lv from dual CONNECT BY LEVEL <= 100) c where c.lv <= t.cntorder by a a c---------------------1 aaa 12 aaa 23 aaa 34 bbb 25 bbb 1

- SQL code
with t as(select 'a,b,c,d' str from dual)SELECT regexp_substr(str, '[^,]+', 1, level) from tconnect by level <= length(str) - length(replace(str, ',', '')) + 1;REGEXP_SUBSTR(STR,'[^,]+',1,LE------------------------------abcd

select regexp_substr(values, '[^,]+',1,levle)
from t
connect by level <= length(values) - length(replace(values,',','')) + 1
