Query for an in between date

Question

I need to make a query that checks to see if the start_date is less than sysdate and the end_date is greater than sysdate
SELECT * FROM table WHERE OFFICE_START_DATE < SYSDATE AND OFFICE_END_DATE > SYSDATE
What is the easiest way of doing this?
Thanks

It wasn't working for me initially but I had to format the date to validate.
SELECT * FROM TABLE WHERE OFFICE_START_DATE < TO_CHAR(SYSDATE, 'YYYY-MM-DD HH24:MI:SS')
AND OFFICE_END_DATE > TO_CHAR(SYSDATE, 'YYYY-MM-DD HH24:MI:SS');As skvaish said, it looks as if your columns are character (varchar2, most likely) and not dates. And if so, your solution is still buggy. You should be doing
select *
from mytable
where to_date(office_start_date) < sysdate
  and  to_date(office_end_date) > sysdate;If you insist on thinking that a chracter string that looks like a date is a date, what do you make of this:
First, create a table with a char column used as a date:
SQL> drop table mydemo;
Table dropped.
SQL> create table mydemo (
  2  alfa_date varchar2(11),
  3  rite_date date
  4  );
Table created.Now insert some data
SQL> --
SQL> insert into mydemo values ('01-JAN-2010', to_date('01-JAN-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('01-FEB-2010', to_date('01-FEB-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('01-APR-2010', to_date('01-APR-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('02-JAN-2010', to_date('02-JAN-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('02-FEB-2010', to_date('02-FEB-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('02-APR-2010', to_date('02-APR-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('03-JAN-2010', to_date('03-JAN-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('03-FEB-2010', to_date('03-FEB-2010','DD-MON-YYYY'));
1 row created.
SQL> insert into mydemo values ('03-APR-2010', to_date('03-APR-2010','DD-MON-YYYY'));
1 row created.
SQL> commit;
Commit complete.Now, select, and order on the alfa-date;
SQL> select * from mydemo order by alfa_date;
ALFA_DATE   RITE_DATE
01-APR-2010 01-APR-10
01-FEB-2010 01-FEB-10
01-JAN-2010 01-JAN-10
02-APR-2010 02-APR-10
02-FEB-2010 02-FEB-10
02-JAN-2010 02-JAN-10
03-APR-2010 03-APR-10
03-FEB-2010 03-FEB-10
03-JAN-2010 03-JAN-10
9 rows selected.Are they in date sequence?
No they are not.
Why not?
Now select, and order on the properly defined date column.
SQL> select * from mydemo order by rite_date;
ALFA_DATE   RITE_DATE
01-JAN-2010 01-JAN-10
02-JAN-2010 02-JAN-10
03-JAN-2010 03-JAN-10
01-FEB-2010 01-FEB-10
02-FEB-2010 02-FEB-10
03-FEB-2010 03-FEB-10
01-APR-2010 01-APR-10
02-APR-2010 02-APR-10
03-APR-2010 03-APR-10
9 rows selected.
