SQL QUERY TO GET TABLESPACE USAGE IN HTML FORMAT ORACLE

SQL QUERY TO GET TABLESPACE USAGE IN HTML FORMAT ORACLE

Everyone like colourful output which looks beautiful.If you ask tablespace usage report in html format to me and i have one for you. Note: You might get “ORA-01476: divisor is equal to zero” error due to size conversion from bytes to GB. If you get the above error, then you can convert bytes to MB using 1048576 in place of 1073741824

SQL Query:

col TOTAL_SPACE format 999999
col TABLESPACE_NAME format a20
col TOTAL_FREE_SPACE format 999999
col UTIL_PCT format 999999
select x.TABLESPACE_NAME,round((x.bytes/1073741824),2) as TOTAL_SPACE_GB,
round(x.bytes/1073741824,2) - round(sum(y.bytes/1073741824),2) as TOTAL_FREE_SPACE_GB,
to_number(round((round(sum(y.bytes/1073741824),2)/round(x.bytes/1073741824,2))*100,2)) as UTIL_PCT
from dba_data_files x
inner join dba_free_space y on x.TABLESPACE_NAME = y.TABLESPACE_NAME
group by x.TABLESPACE_NAME,x.bytes/1073741824;

Normal output:
