Hi,

I want to find difference between two datetime fields in mins:secs.

When I am trying the following query, the output is of format "+000000000 00:02:39.245744".

select JOB_END_TS - JOB_START_TS TIME 
from job_list

Is the output an Interval type or a Float type.

Please also help me how to display only in mins:secs, i.e. removing all unnecessary zeroes.

Thanks

Hi,

I have tried the follwoing query.

select job_nm,
mod( (job_end_ts - job_start_ts)*24, 24 ) )  "Hr", 
mod( (job_end_ts - job_start_ts)*24*60, 60 ) )  "Mi"

Try the following.

select to_char(JOB_END_TS - JOB_START_TS TIME,'HH:MI:SS.FFFFFF')
from job_list

MOD() takes numeric parameters.

You can get most of the way there with CAST:

SQL> WITH ts AS
  2  ( SELECT TIMESTAMP '2000-01-01 00:00:00' AS job_start_ts
  3         , TIMESTAMP '2000-01-01 00:02:39.245744' AS job_end_ts
  4    FROM   dual )
  5  SELECT CAST(job_end_ts - job_start_ts AS INTERVAL DAY(0) TO SECOND(0)) AS elapsed
  6  FROM ts;

ELAPSED

+0 00:02:39
