Re: Problem with query with dates in where clause

Hi,

If the hiredate is inserted as sysdate it inserts upto 1/100th (I believe) of a second the exact time. Than if you querry using sysdate it will use the exact sysdate of querry time which is again 1/100th of a second accurate and will therefore not return anything.
Hiredate could be inserted as trunc(sysdate) which is at the start at midnight of that day and querry using trunc(sysdate).

the second option is not valid you have to use to_date(19-JUN-00,'dd-mon-rr')

Subject: Problem with query with dates in where clause

Hi List,

We have problems in queries which have dates in where clause.

Select * from Emp
where hiredate = sysdate;

Select * from Emp
where hiredate = '19-JUN-00';

The above two queries are not returning any records even though there are some records in the table satisfying the criteria.

Can someone explain why it is so. We don't want to use to_char while comparing.

Thanks in advance,
Shiva.
