Error in timestamp datatype - sql

When I run the below query,
select timestamp '01-01-2017 00:00' log_time from dual
I get this error
ORA-01847: day of month must be between 1 and last day of month.
If it is not valid, How to declare timestamp datatype in oracle?

If you are using ANSI timestamp literals, the value must be formatted in the ISO style yyyy-mm-dd hh24:mi:ss:
select timestamp '2017-01-01 00:00:00' log_time
from dual;
Alternatively use Oracle's to_timestamp() function if you want to keep that format:
select to_timestamp('01-01-2017 00:00', 'dd-mm-yyyy hh24:mi') log_time
from dual

Oracle query time on date fields

I have a column of type DATE stored data are contains date and time . I can see value when i do
select CAST(MSG_DT AS TIMESTAMP) from table;
this is the output
17-MAR-08 15:38:59,000000000
I have to select the row using
Only date
select CAST(MSG_DT AS TIMESTAMP) from
MWRB_RECEIVE where
MSG_DT >= TO_DATE( '2000-02-03' ,'YYYY-MM-DD')
and
MSG_DT <= TO_DATE( '2010-02-03' ,'YYYY-MM-DD')
Only time (eg: every message between 12:00:11 and 23:02:55)
In DB2 i can do
SELECT *
FROM TABLE
WHERE DATE(INS_TMS) = '2014-02-18'
SELECT *
FROM TABLE
WHERE TIME(INS_TMS) > '09.55.00'
In ORACLE I can't see the equivalent.
Try this:
SELECT *
FROM your_table
WHERE TO_CHAR (start_date, 'yyyy-mm-dd') = '2014-10-06'
AND TO_CHAR (start_date, 'hh24:mi:ss') > '10:00:00'
Why are you casting the column value to a TIMESTAMP when the column in the database is a DATE type? The fractional part of the seconds will always be 0, as DATE only has resolution to the seconds value. You need to add the hours,minutes, and seconds format specifier to the query:
select MSG_DT from
MWRB_RECEIVE
where MSG_DT between TO_DATE( '2000-02-03 12:00:11' ,'YYYY-MM-DD HH24:MI:SS') AND
TO_DATE( '2010-02-03 23:02:55' ,'YYYY-MM-DD HH24:MI:SS')
There is no need to split date and hour, you can have it in a single where clause
where field > to_date('20121212 12:12:12, 'YYYYMMDD HH24:MI:SS')
Check for your reference oracle to_date() as it seems the only thing you need

Oracle Convert TIMESTAMP with Timezone to DATE

I have DB with timezone +04:00 (Europe/Moscow) and need to convert a string in format YYYY-MM-DD"T"HH24:MI:SSTZH:TZM to DATE data type in Oracle 11g.
In other words, I have a string 2013-11-08T10:11:31+02:00 and I want to convert it to DATE data type (in local DB timezone +04:00 (Europe/Moscow)).
For string 2013-11-08T10:11:31+02:00 my desired transformation should return DATE data type with date 2013-11-08 12:11:31 (i.e. with local timezone transformation of time to +04:00 (Europe/Moscow)). Timezone of string may be different and +02:00 in string above is just example.
I tried to do this with TIMESTAMP data type, but no success with time zone transformation.
to_timestamp_tz() function with at time zone clause can be used to convert your string literal to a value of timestamp with time zone data type:
SQL> with t1(tm) as(
2 select '2013-11-08T10:11:31+02:00' from dual
3 )
4 select to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM')
5 at time zone '+4:00' as this_way
6 , to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM')
7 at time zone 'Europe/Moscow' as or_this_way
8 from t1
9 /
Result:
THIS_WAY OR_THIS_WAY
----------------------------------------------------------------------------
2013-11-08 12.11.31 PM +04:00 2013-11-08 12.11.31 PM EUROPE/MOSCOW
And then, we use cast() function to produce a value of date data type:
with t1(tm) as(
select '2013-11-08T10:11:31+02:00' from dual
)
select cast(to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM')
at time zone '+4:00' as date) as this_way
, cast(to_timestamp_tz(tm, 'yyyy-mm-dd"T"hh24:mi:ss TZH:TZM')
at time zone 'Europe/Moscow' as date) as or_this_way
from t1
This_Way Or_This_Way
------------------------------------------
2013-11-08 12:11:31 2013-11-08 12:11:31
Find out more about at time zone clause and to_timestamp_tz() function.
SELECT
CAST((FROM_TZ(CAST(timezonefield AS TIMESTAMP),'GMT') AT TIME ZONE 'CET') AS DATE)
FROM table;
Converts a timestamp in GMT to date in Central European time
if you want your timestamp with timezone to convert to a date in sync with "sysdate" then use the following:
select cast(to_timestamp_tz('2013-11-08T10:11:31-02:00'
,'yyyy-mm-dd"T"hh24:mi:sstzh:tzm'
)
at time zone to_char(systimestamp
,'tzh:tzm'
)
as date
)
from dual
to cast time stamp to date :
cast(registrationmaster.Stamp5DateTime as date) >= '05-05-2018' AND
cast(registrationmaster.Stamp5DateTime as date) <= '05-05-2018'
you can manage timezones with CAST(x AT TIME ZONE 'YYYY' AS DATE), this helps me:
WITH t1 (tm) AS (SELECT TIMESTAMP '2021-12-14 15:33:00 EET' FROM DUAL)
SELECT 'EET' tz, CAST (tm AT TIME ZONE 'Europe/Kaliningrad' AS DATE) AS datetime FROM t1
union SELECT 'MSK' tz, CAST (tm AT TIME ZONE 'Europe/Moscow' AS DATE) AS datetime FROM t1
union SELECT 'CET' tz, CAST (tm AT TIME ZONE 'Europe/Prague' AS DATE) AS datetime FROM t1
union SELECT 'UTC' tz, CAST (tm AT TIME ZONE 'UTC' AS DATE) AS datetime FROM t1

Get hour data from date column in oracle

How can I select data between two date with hours. My oracle column date's format is:10.04.2006 19:10:37 I can select between twou days with:
select date from table where date between '1/1/2011' and '2/1/2011
but I will select between hours which hours are in date column i.e:
select date from table where date between '1/1/2011 22:00'and '2/1/2011 21:00' what can I do
You can use to_date to specify a custom date format:
where date between to_date('1/1/2011 22:00', 'DD/MM/yyyy HH24:MI')
and to_date('2/1/2011 21:00', 'DD/MM/yyyy HH24:MI')
This is the way I usually do.
where date between date'2011-1-1'+22/24 and date'2011-1-2'+21/24
On the column
TRUNC(date_col)+hours/24

Insert TIME into Oracle SQL, DATE field

Is there anyway to insert only time (no date) into a SQL field of type 'Date'
I have tried inserting:
13:00
and
01:00
and
13:00pm
and
01:00pm
But keep getting the error:
Not A Valid Month
The problem is the literal. For date/time values, Oracle expects values in the form ddMMMyyyy. (Or, you can use the expression DATE '2001-01-01. Literal values are explained here.) There doesn't appear to be a default format for time without a date.
In other words, you can get the same error with cast('1/1/2001' as date).
Instead, use the to_date() function:
select to_date('10:00', 'hh:mi')
from dual
This gives you much more flexibility with formats.
Also, as Ben notes in the comments, this gives you the current date with the time specified.
Example of using EXTRACT and time only portion of a SYSDATE and some date...:
SELECT hh||':'||mi||':'||ss time_only_portion
FROM
(
Select
EXTRACT(hour From Cast(SYSDATE as timestamp)) hh,
EXTRACT(minute From Cast(SYSDATE as timestamp)) mi,
EXTRACT(second From Cast(SYSDATE as timestamp)) ss
From dual
)
/
SELECT EXTRACT(HOUR From t_stamp) hh
FROM
(
SELECT CAST(to_date('21/02/2012 06:10:00 am', 'dd/mm/yyyy hh:mi:ss am') AS TIMESTAMP) t_stamp
FROM dual
)
/

Oracle Timestamp Conversion with Dates

Assuming this has a simple solution, but I can't find it.
I'm trying to do some logic on a DATE field in Oracle. My desire is to take a DATE field and subtract X hours from it.
For instance: SELECT A.MyDATE - 100 Hours from dual;
however, I need a result in a timestamp format 'YYYY-MM-DD hh:mm'.
I've tried CAST(A.MyDATE as TIMESTAMP) - NUMTODSINTERVAL(100/24,'day') however it didn't work.
I found out that the issue is that the MyDATE field when cast to a timestamp still contained some residual time elements. How can I reset these??
Thanks!
You can just do this with subtraction:
select a.MyDate - 100.0/24
To convert to varchar:
select to_char(a.MyDate - 100.0/24, 'YYYY-MM-DD')
And, if you want to get rid of that pesky time on the date:
select trunc(a.MyDate - 100.0/24) as JustTheDate
The formats and dates in my example can be changed to any other formats and dates:
SELECT To_Timestamp(To_Char(Sysdate - INTERVAL '100' HOUR, 'MM/DD/YYYY HH24:MI'), 'MM/DD/YYYY HH24:MI')
FROM dual
/
Output:
2/4/2013 10:18:00.000000000 AM
To remove time element add Trunc() to any of your dates...:
SELECT Trunc(To_Timestamp(To_Char(Sysdate - INTERVAL '100' HOUR, 'MM/DD/YYYY HH24:MI'), 'MM/DD/YYYY HH24:MI'))
FROM dual
/
Output: 2/4/2013
Conversion/Casting - when using other dates in place of sysdate then add formats as in my other examples:
SELECT CAST(SYSDATE AS TIMESTAMP) - INTERVAL '100' HOUR FROM dual
/
Output: 2/4/2013 10:26:35.000000000 AM
SELECT start_date tstamp_to_date, CAST(start_date AS timestamp) date_to_tstamp FROM
(
SELECT to_date(to_char(to_timestamp ('2013-02-07 10:07:47.000' , 'YYYY-MM-DD HH24:MI:SS.FF'),'DD-MON-YYYY HH24:MI:SS'), 'DD-MON-YYYY HH24:MI:SS') start_date
FROM dual
)
/
Output:
tstamp_to_date date_to_tstamp

In Oracle, a DATE always has a day and a time component. Depending on the tool you are using and your session's NLS_DATE_FORMAT, it is entirely possible that the tool may not display the time component when you look at the data. But that is simply a display question, it has no impact on the actual data.
If you want to subtract 100 hours from midnight on the day that MyDate represents
SELECT TRUNC(MyDate) - interval '100' hour
FROM dual
This will return a DATE. If you want to return a string in a particular format
SELECT TO_CHAR( TRUNC(MyDate) - interval '100' hour, 'YYYY-MM-DD hh:mi am' )
FROM dual
Note that I'm assuming that there was a typo in your question. I assume that you want to display the minutes after the hour (mi) rather than the month (mm).
I am trying to fetch the records which is older than 30 days (from Mod_date) and I am using the below query and it is returning all the data and I want only 30 days old data.
Sample :- Mod_date 03-NOV-12 12.00.00.000000000 AM
Query :-
select Mod_date from fil_cnfact where Mod_date <= sysdate -30 order by Mod_date asc ;
