Hi all,
on 11.2.0.4 on Oracle Linux:
The following runs but with an error:
SQL> select begindttm,RQSTDTTM, ((begindttm - RQSTDTTM)*86400) st_elap_s FROM psprcsrqst;

ERROR:
ORA-01873
To avoid division by 0:
I tried with :
SQL> select begindttm,RQSTDTTM, ((begindttm - RQSTDTTM)*86400) st_elap_s FROM psprcsrqst where begindttm is not null;
And I have the same error.
Thanks.
