I have SQL query as follow
MONTH(ADD_MONTHS(TRAN_DATE,1))
and then in oracle extract function for month I have
EXTRACT(MONTH FROM TRAN_DATE)
So now how do I add month in Extract function in oracle query like SQL query
Assuming that you mean SQL-Server when talking about SQL, is this what you want?
EXTRACT( MONTH FROM ADD_MONTHS( tran_date, 1 ) )
The following might work for you:
select EXTRACT( MONTH FROM ADD_MONTHS( sysdate, 1 ) ) from dual

This is how my Date column looks like
RPT_DT (Data Type is Number)
20180131
20180130
20180129
I wanna extract month out of these dates(either Month or mm), and I tried below
select extract(month from to_date(Rpt_dt))
from
(
select distinct to_char(to_date(RPT_DT,'yyyymmdd'),'mm/dd/yyyy') Rpt_dt
from TABLE_NAME
)
I am getting the error "Not a valid month"
if there is not any particular reason to have a double conversion I would suggest you to handle the problem with this simple query:
select substr(to_char(RPT_DT),5,2)from THE_TABLE
this query should be more performant since it make only one conversion. in your sample you transform:
a number to a date
then a date to a char
the char again in date
finally you extract the month
let me know if it help
r.
try this,
SELECT EXTRACT(MONTH FROM TO_DATE(rpt_dt, 'YYYYMMDD'))
FROM TABLE_NAME;
and I believe you need to modify your query as you did not put the format 'MM/DD/YYYY',
select extract(month from to_date(Rpt_dt, 'MM/DD/YYYY'))
from
(
select distinct to_char(to_date(RPT_DT,'yyyymmdd'),'mm/dd/yyyy') Rpt_dt
from TABLE_NAME
)
This back-and-forth conversion is useless. Try this
select
extract(month from to_date(RPT_DT,'yyyymmdd'))
from TABLE_NAME;
I need to bring the day immediately preceding date in Oracle using a truncate but not how. He was using the following line but bring me some records for the current day of execution and should not be. Neceisto only the previous day; investigation found the truncate with dates in Oracle but not how to use it.
and fnxs.FECHA_INGRESO BETWEEN (TO_CHAR (SYSDATE-1, 'DD-MON-YY')) AND (TO_CHAR (SYSDATE, 'DD-MON-YY'));
I appreciate your help
Using BETWEEN with dates in Oracle is generally a bad idea. I see it all the time, and most of the time people get it wrong (like in the accepted answer above). Even when they fully understand that the two dates are included, they still make logical errors because they forget about timestamps.
The OP is asking for yesterday dates. The following sql shows that today falls within "BETWEEN TRUNC( SYSDATE ) - 1 AND TRUNC( SYSDATE )"
with adate as (
select trunc(sysdate) today from dual
) select today from adate where today between trunc(sysdate) -1
and trunc(sysdate);
16-Apr-15 00:00:00
[returns the record for today]
I find it easier to be correct with dates when you're more explicit about the end points:
SELECT * from your_table
WHERE fnxs.FECHA_INGRESO >= TRUMC(SYSDATE) - 1
AND fnxs.FECHA_INGRESO < TRUNC(SYSDATE);
Upon looking closer, the OP's date-like column might be a VARCHAR2 (could still be a date that was implicitly cast in the comparison he gave). If it is a VARCHAR, then it needs to be converted first (using an appropriate format string):
SELECT * FROM your_table
WHERE TO_DATE(fnxs.FECHA_INGRESO, 'DD-MON-YY') >= TRUMC(SYSDATE) - 1
AND TO_DATE(fnxs.FECHA_INGRESO, 'DD-MON-YY') < TRUNC(SYSDATE);
Assuming your column is of type DATE
SELECT *
FROM TABLE_NAME
WHERE FECHA_INGRESO BETWEEN TRUNC( SYSDATE ) - 1
AND TRUNC( SYSDATE );
If it is a character string then:
SELECT *
FROM TABLE_NAME
WHERE TO_DATE( FECHA_INGRESO, 'DD-MON-YY' )
BETWEEN TRUNC( SYSDATE ) - 1
AND TRUNC( SYSDATE );
I have database, where i have inserted timestamps(6) in this format :
18-AUG-14 02.49.27.000000000 PM .
I want to extract it into this: 2014-08
Its called ISO 8601
You'll need to use the to_char function to extract the year-month from timestamp.
select to_char(timestamp, 'yyyy-mm') from your_table
I've done this in this way -
select extract(year from timestmp) || '-' || extract(month from timestmp) from texmp1;
Hope this helps.
Here is the table structure:
create table texmp1
(
timestmp timestamp
);
select TO_CHAR(to_date(sysdate, 'DD-MON-YYYY'), 'DAY') FROM DUAL;
When I run this query the output was : SUNDAY. But we know today is Tuesday(1-1-2013).
And
then changed the query as
select TO_CHAR(to_date('01-JAN-2013', 'DD-MON-YYYY'), 'DAY') FROM DUAL;
answer was :TUESDAY.
then Changed query as
select TO_CHAR(to_date(sysdate+1, 'DD-MON-YYYY'), 'DAY') FROM DUAL;
answer is :MONDAY.
When I using the sysdate why it is show SUNDAY as output?
I am new in oracle db. Please help me.
use this:
select TO_CHAR(sysdate, 'DAY') FROM DUAL;
you are using this :
to_date(sysdate, 'DD-MON-YYYY')
which is giving you date=1/1/0013 which is sunday
Please refer the documentation for sysdate here. Sysdate is already a date data type.
Your example query is inappropriate as to_date function takes first parameter as String not date.
Try the simple query below:
select TO_CHAR(sysdate, 'DAY') FROM DUAL;
This should return TUESDAY as output.
To_date is used to convert a strin to date. As sysdate is already a date, one must not add add to_date.
I've got a question about date function on oracle.
I have the following table
statistic_table(
pages AS varchar(10),
date_created AS date
);
I have the following sql
SELECT COUNT(*) FROM statistic_table WHERE date_created BETWEEN sysdate-5 AND sysdate-1
and
SELECT COUNT(*) FROM statistic_table WHERE date_created BETWEEN to_date('12-AUG-2011') AND to_date('16-AUG-2011');
the question is, why is it return different numbers. assuming sysdate-5 returns 12-aug-2011 and sysdate-1 returns 16-aug-2011
Any help would be much appreciated!
Cheers,
sysdate - 5 will give you a date with the current time. So if I ran it at 1pm precisely, the query would be equivalent to:
select (*)
FROM statistic_table
WHERE date_created BETWEEN to_date('12-Aug-2011 13:00:00')
AND to_date('16-Aug-2011 13:00:00')
whereas the second query is:
select (*)
FROM statistic_table
WHERE date_created BETWEEN to_date('12-Aug-2011 00:00:00')
AND to_date('16-Aug-2011 00:00:00')
you should probably try this instead:
select (*)
FROM statistic_table
WHERE date_created BETWEEN trunc(sysdate) -5
AND trunc(sysdate) -1
A date in Oracle is a point in time with a precision of a second.
SYSDATE returns the current date and time and is therefore not the same as to_date('17-AUG-2011'):
SQL> SELECT to_char(sysdate, 'dd-mon-yyyy hh24:mi:ss') FROM DUAL;
TO_CHAR(SYSDATE,'DD-MON-YYYYHH
------------------------------
17-aug-2011 15:52:13
Use the TRUNC function if you only want the date component:
SQL> SELECT to_char(trunc(sysdate), 'dd-mon-yyyy hh24:mi:ss') FROM DUAL;
TO_CHAR(TRUNC(SYSDATE),'DD-MON
------------------------------
17-aou-2011 00:00:00
Because SYSDATE includes a time component, so if the current time is 11:22:33, then
SELECT COUNT(*) FROM statistic_table
WHERE date_created BETWEEN sysdate-5 AND sysdate-1
is actually equivalent to
SELECT COUNT(*) FROM statistic_table
WHERE date_created BETWEEN to_date('12-AUG-2011 11:22:33','DD-MON-YYYY HH24:MI:SS')
AND to_date('16-AUG-2011 11:22:33','DD-MON-YYYY HH24:MI:SS')
To avoid the time component do this:
SELECT COUNT(*) FROM statistic_table
WHERE date_created BETWEEN TRUNC(sysdate)-5 AND TRUNC(sysdate)-1
An Oracle DATE always has a day and a time component.
sysdate-5 returns a date exactly 5 days ago. If today is August 17 at 10 AM, for example, sysdate-5 returns August 12 at 10 AM.
to_date('12-AUG-2011', 'DD-MON-YYYY'), on the other hand, returns August 12 at midnight. So it returns a date that is 10 hours earlier than sysdate-5.
sysdate auto returns with a time component as mentioned by the previous answers.
When using to_date it is converting a string to a date. With this being said you can pass in parameters to make it return the same thing.
Have a look at this link that explains it.
