select
to_timestamp(SCHEDULED_TIME,'YYYY-MM-DD HH24:MI:SS.FF') as SCHEDULED_TIME,

The error was:
ORA-01830: date format picture ends before converting entire input string
01830. 00000 - "date format picture ends before converting entire input string"
The goal is to return something like
2017-07-91 23:14:00
(without the content after the dot).
Here's what the SCHEDULED_TIME (timestamp) looked like:
The problem in your attempt is the function TO_DATE() applied to a timestamp. TO_DATE() takes a VARCHAR2 (string) input, not a timestamp. So Oracle converts the timestamp to a string first, implicitly, using your NLS_TIMESTAMP_FORMAT parameter, and then attempts to convert this string to a date. Depending on your NLS_TIMESTAMP_FORMAT, you may get different errors.
The way to convert a timestamp to a date (datetime) - while truncating off the fractions of a second - is with the CAST function. Example:
select systimestamp,
cast (systimestamp as date) as ts_cast_to_date
from dual
;
Alternatively, if all your strings are EXACTLY in that format, you can truncate the strings first and apply TO_DATE directly:
to_date(substr(scheduled_time, 1, 19), 'yyyy-mm-dd hh24:mi:ss')
This should do the trick:
select
to_char(SCHEDULED_TIME,'YYYY-MM-DD HH24:MI:SS.FF') as time_to_csecs,
to_char(SCHEDULED_TIME,'YYYY-MM-DD HH24:MI:SS') as time_to_secs,
TRUNC(to_date(to_char(SCHEDULED_TIME,'YYYY-MM-DD HH24:MI:SS'),'YYYY-MM-DD HH24:MI:SS')) as time_to_day
from S_TIDAL_STATUS
Please review the docs to see the difference between to_timestamp and to_char.

I have that field in my table:
2020-01-16T10:55:16..296518000
How to convert this Varchar into a date in format 'YYYY-MM-DD' ?
I tried:
select TRUNC(to_date(DATE_UPDATED ,'YYYY-MM-DD hh24:mi:ss')) from JOB_SCHEDULE_TBL
but I'm getting an error:
ORA-01830: date format picture ends before converting entire input string
Just use substr():
select to_date(SUBSTR(DATE_UPDATED, 1, 10) ,'YYYY-MM-DD')
The trunc() is unnecessary.
You are confusing the format of DATE with what you are seeing on the screen. A DATE data type has no "format". It's Oracle's internal, binary format. Even when you SELECT TO_DATE ..., the result is going to get displayed by the client, and to do so the client will have to peform (under the covers) a TO_CHAR on the resulting DATE. And that implied to_char will use the current system/session/ settings for TNS_DATE_FORMAT.
I have utc epocha in millisecond and I would like my sql return resulting dates in a specific date format.
This works
SELECT to_timestamp(timestamp / 1000) as date
FROM data
This does not work
SELECT to_timestamp(timestamp / 1000, 'YYYY-MM-DD HH:MI:SS') as date
FROM data
Could you tell me what is wrong in my script and how to fix it please? Thanks
to_timestamp() does not format your output. The version where to_timestamp() accepts a format mask is used to convert a string value to a proper timestamp.
You need to format the result of your conversion (which is a proper timestamp) using to_char().
to_char(to_timestamp(timestamp / 1000), 'yyyy-mm-dd hh24:mi:ss') as date
i have a date in oracle with this format DD-MM-YYY and i want to convert it to datetime with this other format DD-MM-YYY HH24:MI how can i proceed?
I've tried this but nothing is working :
to_date(the_date,'DD-MM-YYY HH24:MI')
and also this:
to_date(to_char(date_debut_p),'DD-MM-YYY HH24:MI')
i have a date in oracle with this format DD-MM-YYY and i want to convert it to datetime with this other format DD-MM-YYY HH24:MI
No, you are confused. Oracle does not store dates in the format you see. It is internally stored in 7 bytes with each byte storing different components of the datetime value.
DATE data type always has both date and time elements up to a precision of seconds.
If you want to display, use TO_CHAR with proper FORMAT MODEL.
For example,
SQL> select to_char(sysdate, 'mm/dd/yyyy hh24:mi:ss') from dual;
TO_CHAR(SYSDATE,'MM
-------------------
11/25/2015 22:25:42
Oracle DATE datatype ALWAYS contains (stores) time.
If you want to see it, you can use function TO_CHAR.
If you want to add, for example, 1 hour, you can just use date_debut_p+1/24.
If you want to covert to timestamp, you can do the following:
Select to_timestamp(date_column, 'DD-MM-YYY') from table;
However, if you want in the required format, you can do the following:
Select to_char(to_timestamp(date_column, 'DD-MON-YY'), 'DD-MM-YYY HH24:MI')
from table;
Hope it helps..
I have a varchar2 field in my db with the format of for example -
2015-08-19 00:00:01.0
2014-01-11 00:00:01.0
etc.
I am trying to convert this to a date of format DD-MON-YYYY. For instance, 2015-08-19 00:00:01.0 should become 19-AUG-2015. I've tried
select to_date(upgrade_date, 'YYYY-MM-DD HH24:MI:SS') from connection_report_update
but even at this point I'am getting ORA-01830 date format ends before converting the entire input string. Any ideas?
You have details upto milli seconds, for which, you have to use TO_TIMESTAMP() with format model 'FF'
select to_timestamp('2015-08-19 00:00:01.0' ,'YYYY-MM-DD HH24:MI:SS.FF') as result from dual;
RESULT
---------------------------------------------------------------------------
19-AUG-15 12.00.01.000000000 AM
And Date doesn't have a format itself, only the date output can be in a format. So, when you want it to be printed in a different format, you would need to again use a TO_CHAR() of the converted timestamp;
select to_char(to_timestamp('2015-08-19 00:00:01.0' ,'YYYY-MM-DD HH24:MI:SS.FF'),'DD-MON-YYYY') as result from dual;
RESULT
-----------
19-AUG-2015
Why do you store datetimes in a string???
Anyhow. To get from '2015-08-19 00:00:01.0' to a datetime with milliseconds (which is a TIMESTAMP in Oracle) use to_timestamp:
to_timestamp('2015-08-19 00:00:01.0', 'yyyy-mm-dd hh24:mi:ss.ff')
Then to get the desired output format, use to_char:
to_char(thedate, 'DD-MON-YYYY')
Together:
to_char(to_timestamp('2015-08-19 00:00:01.0', 'yyyy-mm-dd hh24:mi:ss.ff'), 'DD-MON-YYYY')
You should be specifying the format that you want in the call of to_date not the current format:
select to_date(upgrade_date, 'DD-MM-YYYY') from connection_report_update
I need to create a oracle plsql script which have input param v_date as Timestamp with time zone type.
Also I need to verify whether the format of the v_date is as per mentioned format 'YYYY-MM-DD HH24:MI:SS TZH:TZM' or not .
How should I achieve this?
I was thinking of achieveing this by changing input param v_date as String and then convert this string into Timestamp with time zone and if any error occured while converting then conclude that the format is wrong. But it seems TO_TIMESTAMP_TZ functions doesn't throw error when the date string is in different format w.r.t the specified format instead it converts it.
For e.g.
SELECT TO_TIMESTAMP_TZ('15-APR-15',
'YYYY-MM-DD HH:MI:SS TZH:TZM') FROM DUAL;
Actual result : 14-APR-15 11.50.00.000000000 PM AMERICA/CHICAGO
Expected result : Some error as format is not as per 'YYYY-MM-DD HH:MI:SS TZH:TZM'
In short I want to know how to verify the format of Timestamp with time zone type.
You could try adding the "fx" modifier to the format, which says to Oracle "expect this exact format":
SELECT TO_TIMESTAMP_TZ('15-APR-15 ', 'fxYYYY-MM-DD HH:MI:SS TZH:TZM') FROM DUAL;
SELECT TO_TIMESTAMP_TZ('15-APR-15 ', 'fxYYYY-MM-DD HH:MI:SS TZH:TZM') FROM DUAL
