–the following is my try :)

WITH DATA AS (
SELECT LTRIM(sys_connect_by_path(num,’+'),’+') str_num,REPLACE(sys_connect_by_path(num,’.'),’.') str_out
FROM (SELECT LEVEL-1 num
FROM dual
CONNECT BY LEVEL <= 10)
WHERE LEVEL = 3
CONNECT BY LEVEL <= 3
)
SELECT s.str_out, decode(ROWNUM,1,COUNT(*) OVER(),NULL) cnt FROM DATA s
WHERE dbms_aw.eval_number(s.str_num) = 9;

Comment on How to check free space in tablespaces by chanjaljayaram

Hello Karl,

I think the query needs to be slightly modified as below.

case
when(d.contents = ‘TEMPORARY’) then
to_char(nvl(t.bytes / 1024 / 1024, 0),
’99G999G990D90′, ‘NLS_NUMERIC_CHARACTERS = ”,.” ‘)
else
to_char(nvl(a.bytes / 1024 / 1024, 0),
’99G999G990D90′, ‘NLS_NUMERIC_CHARACTERS = ”,.” ‘)
end as “Size (M)”,

** I believe the columns t.bytes and a.bytes were reversed in your query.
