with TMP_T as
(
select 1 as no,'T' as nm from dual
union all
select 1 as no,'A' as nm from dual
union all
select 3 as no,'B' as nm from dual
union all
select 4 as no,'C' as nm from dual
union all
select 5 as no,'D' as nm from dual
union all
select 6 as no,'E' as nm from dual
)
select (SELECT MAX(NO) +1 from TMP_T),NM
from TMP_T
where no = 1

제가 원하는 결과는

7 T

8 A 라는 결과를 원하는데

위의 쿼리에서 조회된느값은

7 T

7 A로 나오네요 어덯게 해야될까요?

이런 식일까요?

with TMP_T as
(
select 1 as no,'T' as nm from dual
union all
select 1 as no,'A' as nm from dual
union all
select 3 as no,'B' as nm from dual
union all
select 4 as no,'C' as nm from dual
union all
select 5 as no,'D' as nm from dual
union all
select 6 as no,'E' as nm from dual
)
select (SELECT MAX(no) from TMP_T) + ROWNUM, NM
from TMP_T
where no = 1
order by no;
