For example I have in table row finish with values:
20-JAN-06;
21-SEP-06;
12-FEB-10;
15-MAR-09;
03-JUL-09;
23-JAN-09;
How can I compare them against sysdate? I know that this code is not correct:
Select name from project where finish <= sysdate ;
Why not use the ANSI standard CURRENT_TIMESTAMP?
SELECT * FROM SomeTable WHERE Finish <= CURRENT_TIMESTAMP;
Fiddle here
Something like that try cos I don't have oracle to test it
SELECT EMP_NAME, EMPNO
FROM EMP
WHERE TRUNC(START_DATE) = TRUNC(SYSDATE);
or
SELECT emp_name, empno
FROM emp
WHERE start_date >= TRUNC(SYSDATE)
and start_date < TRUNC(SYSDATE)+1
Select name
from project
where to_date(finish, 'DD-MON-YY') <= trunc(sysdate)

I have a few dates in the YYYY-MM-DD format in the table column. how can I find the nearest date, less than or equal to today?
Normally I would use:
<= (SELECT TO_CHAR (TRUNC (SYSDATE), 'YYYY-MM-DD') from DUAL)
but it will return all values less or equal, and I only want one, the nearest.
Thanks for help.
One method is:
select t.*
from (select t.*
from t
where datecol < sysdate -- trunc(sysdate) ???
order by datecol desc
) t
where rownum = 1;
I would like to select 1 if current date falls between 2 dates through Oracle SQL.
I wrote an SQL after reading through other questions.
https://stackoverflow.com/questions/2369222/oracle-date-between-query
https://stackoverflow.com/questions/2399753/select-from-table-by-knowing-only-date-without-time-oracle
But it returned only null. sysdate is the current date that is 01/05/2014 in date format DD/MM/YYYY.
The SQL I wrote is:
select 1 from dual
WHERE to_date(sysdate,'DD/MM/YYYY')
BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY')
AND TO_DATE('20/06/2014', 'DD/MM/YYYY');
and
select 1 from dual
WHERE to_date(sysdate,'DD/MM/YYYY') >= TO_DATE('28/02/2014', 'DD/MM/YYYY')
AND to_date(sysdate,'DD/MM/YYYY') < TO_DATE('20/06/2014', 'DD/MM/YYYY');
You don't need to apply to_date() to sysdate. It is already there:
select 1
from dual
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');
If you are concerned about the time component on the date, then use trunc():
select 1
from dual
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
TO_DATE('20/06/2014', 'DD/MM/YYYY');
SELECT to_char(emp_login_date,'DD-MON-YYYY HH24:MI:SS'),A.*
FROM emp_log A
WHERE emp_login_date BETWEEN to_date(to_char('21-MAY-2015 11:50:14'),'DD-MON-YYYY HH24:MI:SS')
AND
to_date(to_char('22-MAY-2015 17:56:52'),'DD-MON-YYYY HH24:MI:SS')
ORDER BY emp_login_date
TSQL: Dates- need to look for gaps in dates between Two Date
select
distinct
e1.enddate,
e3.startdate,
DATEDIFF(DAY,e1.enddate,e3.startdate)-1 as [Datediff]
from #temp e1
join #temp e3 on e1.enddate < e3.startdate
/* Finds the next start Time */
and e3.startdate = (select min(startdate) from #temp e5
where e5.startdate > e1.enddate)
and not exists (select * /* Eliminates e1 rows if it is overlapped */
from #temp e5
where e5.startdate < e1.enddate and e5.enddate > e1.enddate);
In oracle use below,
select * from table_name where date_column_name between to_date('1-OCT-22') and ('31-OCT-22')
PS: replace table name and date column name and format accordingly
I have an oracle table that store transaction and a date column. If I need to select records for one year say 2013 I do Like this:
select *
from sales_table
where tran_date >= '01-JAN-2013'
and tran_date <= '31-DEC-2013'
But I need a Straight-forward way of selecting records for one year say pass the Parameter '2013' from an Application to get results from records in that one year without giving a range. Is this Possible?
Use the extract function to pull the year from the date:
select * from sales_table
where extract(YEAR from tran_date) = 2013
You can use to_date function
http://psoug.org/reference/date_func.html
select *
from sales_table
where tran_date >= to_date('1.1.' || 2013, 'DD.MM.YYYY') and
tran_date < to_date('1.1.' || (2013 + 1), 'DD.MM.YYYY')
solution with explicit comparisons (tran_date >= ... and tran_date < ...) is able to use index(es) on tran_date field.
Think on borders: e.g. if tran_date = '31.12.2013 18:24:45.155' than your code tran_date <='31-DEC-2013' will miss it
select last_name,hire_date
from employees
where extract(year from hire_date) = 2006;
select FIRST_NAME , to_char(hire_date, 'YYYY') YR FROM employees where to_char(hire_date, 'YYYY')= '2006'
select * from table_name where YEAR(date_column_name) = 2019
I have the query below where the date is hard-coded. My objective is to remove the harcoded date; the query should pull the data for the previous month when it runs.
select count(distinct switch_id)
from xx_new.xx_cti_call_details#appsread.prd.com
where dealer_name = 'XXXX'
and TRUNC(CREATION_DATE) BETWEEN '01-AUG-2012' AND '31-AUG-2012'
Should I use sysdate-15 function for that?
Modifying Ben's query little bit,
select count(distinct switch_id)
from xx_new.xx_cti_call_details#appsread.prd.com
where dealer_name = 'XXXX'
and creation_date between add_months(trunc(sysdate,'mm'),-1) and last_day(add_months(trunc(sysdate,'mm'),-1))
The trunc() function truncates a date to the specified time period; so trunc(sysdate,'mm') would return the beginning of the current month. You can then use the add_months() function to get the beginning of the previous month, something like this:
select count(distinct switch_id)
from xx_new.xx_cti_call_details#appsread.prd.com
where dealer_name = 'XXXX'
and creation_date >= add_months(trunc(sysdate,'mm'),-1)
and creation_date < trunc(sysdate, 'mm')
As a little side not you're not explicitly converting to a date in your original query. Always do this, either using a date literal, e.g. DATE 2012-08-31, or the to_date() function, for example to_date('2012-08-31','YYYY-MM-DD'). If you don't then you are bound to get this wrong at some point.
You would not use sysdate - 15 as this would provide the date 15 days before the current date, which does not seem to be what you are after. It would also include a time component as you are not using trunc().
Just as a little demonstration of what trunc(<date>,'mm') does:
select sysdate
, case when trunc(sysdate,'mm') > to_date('20120901 00:00:00','yyyymmdd hh24:mi:ss')
then 1 end as gt
, case when trunc(sysdate,'mm') < to_date('20120901 00:00:00','yyyymmdd hh24:mi:ss')
then 1 end as lt
, case when trunc(sysdate,'mm') = to_date('20120901 00:00:00','yyyymmdd hh24:mi:ss')
then 1 end as eq
from dual
;
SYSDATE GT LT EQ

Data for last month-
select count(distinct switch_id)
from xx_new.xx_cti_call_details#appsread.prd.com
where dealer_name = 'XXXX'
and to_char(CREATION_DATE,'MMYYYY') = to_char(add_months(trunc(sysdate),-1),'MMYYYY');
I believe this would also work:
select count(distinct switch_id)
from xx_new.xx_cti_call_details#appsread.prd.com
where
dealer_name = 'XXXX'
and (creation_date BETWEEN add_months(trunc(sysdate,'mm'),-1) and trunc(sysdate, 'mm'))
It has the advantage of using BETWEEN which is the way the OP used his date selection criteria.
It is working with me in Oracle sql developer
SELECT add_months(trunc(sysdate,'mm'), -1),
last_day(add_months(trunc(sysdate,'mm'), -1))
FROM dual
Getting last nth months data retrieve
SELECT * FROM TABLE_NAME
WHERE DATE_COLUMN BETWEEN '&STARTDATE' AND '&ENDDATE';
If I have table with a Date column (Date field) called created_date, with values like "9/2/2010 5:25:42 PM".
I want to select all rows from a start_date to a end_date. However, the end_date may be null. In this case, I want to select all rows where created_date is greater than end_date.
Since toDate (which can be null) is a host variable, it's easier than the solutions already given (which are all wrong in that regard, btw)
select * from mytable
where created_date between v_fromdate
and nvl(v_todate, to_date('31.12.9999','dd.mm.yyyy'));
select *
from TABLE
where created_date >= '2010-09-02' and (created_date is NULL or created_date <= '2010-09-03')
Why just use a simple SQL query for that, like this one:
select xxx from table_names where created_date is null or (created_date >= to_date("02/09/2010", "dd/mm/yyyy") and created_date <= to_date("03/09/2010", "dd/mm/yyyy"));
Edit
You can define a query like the one defined by ammoQ, i.e. something like that:
select xxx from table_names where created_date is null or created_date >= start_date and created_date <= nvl(end_date, to_date("31/12/9999", "dd/mm/yyyy"));
However, as you are using PL/SQL, you can check the nullability of end_date parameter:
IF end_date IS NULL THEN
select xxx from table_names where created_date is null or created_date >= start_date;
ELSIF
select xxx from table_names where created_date is null or created_date >= start_date and created_date <= end_date;
END IF;
Note that you can remove the created_date is null condition if created_date is not a nullable column...
select * from yourtable
where created_date >= #StartDate AND created_date <=ISNULL(#EndDate,created_date)
SELECT *
FROM A_TABLE
WHERE CREATED_DATE >= &START_DATE AND
(CREATED_DATE <= &END_DATE OR
&END_DATE IS NULL)
If i took it right from your question
this should work:
SELECT *
FROM yourTable
WHERE created_date >= to_date('01.09.2010', 'dd.mm.yyyy')
AND (end_date <= to_date('02.09.2010', 'dd.mm.yyyy')
OR end_date IS NULL);
