My table has two DATE format attributes, however, when i try to insert value it throws an error: date format picture ends before converting entire input string.
Here is my attempted code:
insert into visit
values(123456, '19-JUN-13', '13-AUG-13 12:56 A.M.');
I think the problem is with 12:56 but Oracle documentation says date implies both date and time.
Perhaps you should check NLS_DATE_FORMAT and use the date string conforming the format.
Or you can use to_date function within the INSERT statement, like the following:
insert into visit
values(123456,
to_date('19-JUN-13', 'dd-mon-yy'),
to_date('13-AUG-13 12:56 A.M.', 'dd-mon-yyyy hh:mi A.M.'));
Additionally, Oracle DATE stores date and time information together.
you need to alter session
you can try before insert
sql : alter session set nls_date_format = 'YYYY-MM-DD HH24:MI:SS'
What you're trying to insert is not a date, I think, but a string. You need to use to_date() function, like this:
insert into table t1 (id, date_field) values (1, to_date('20.06.2013', 'dd.mm.yyyy'));
I had this error today and discovered it was an incorrectly-formatted year...
select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')
Notice the year has only three 'y's. It should have 4.
Double-check your format.

I am using SAP BODS and I am trying to fetch data from an ORACLE server using SQL query transormation. Now The table has a column named latest_changed_date which is a datetime column. I only want yesterday and current day data from that table. Now since the column is datetime, I need to convert it to date, but when I am using to_date function I get the following error.
SELECT *
FROM ABC.TEST
WHERE TO_DATE(LATEST_CHANGED_DATE) = TO_DATE(SYSDATE-1)
The database error message is
ORA-01843: not a valid month
I tried giving date format in TO_DATE condition as below:
SELECT *
FROM ABC.TEST
WHERE TO_DATE(LATEST_CHANGED_DATE,'YYYY-MM-DD') >= TO_DATE(SYSDATE-1,'YYYY-MM-DD')
Here I got the error:
date format picture ends before converting entire input string
I used trunc function also and again got either:
not a valid month
or
inconsistent datatypes: expected NUMBER got DATE
Below is a sample data for the column. I just need data for current and day before data from the column.
Update: I think the main issue is that I am not able to determine the proper datatype for the column in the source table and currently I don't have an option to determine that.
Rather than trying to implicitly cast your dates to strings and convert them back using TO_DATE( string_value, format_model ) you can use TRUNC() to truncate SYSDATE to the start of the day:
SELECT *
FROM ABC.TEST
WHERE LATEST_CHANGED_DATE >= TRUNC( SYSDATE-1 )
this will work:
SELECT *
FROM ABC.TEST
where sysdate-LATEST_CHANGED_DATE<=sysdate-(sysdate-2);
for example take this:
ALTER SESSION SET NLS_DATE_FORMAT = ' DD-MON-YYYY HH24:MI:SS';
SELECT * FROM d061_dates ;
03-DEC-2018 17:44:38
25-AUG-2018 17:44:42
30-AUG-2018 17:44:46
01-DEC-2018 17:44:49
02-DEC-2018 17:46:31
SELECT * FROM d061_dates
where sysdate-a<=sysdate-(sysdate-2);
03-DEC-2018 17:44:38
02-DEC-2018 17:46:31
you have to take sysdate minus on both sides to get comparision by a number which is less than equal to 2 to get day and day before yesterday and its giving the correct output.
thank you!!!!!!!!!!!!!
In Oracle 12, if I create a very simple table, TEST_TABLE, with a single varchar2(128) column 'name' and populate that column with lots of strings of '20170831', and my sysdate shows:
SELECT sysdate FROM dual;
29-SEP-17
then why does this SQL query return 0 rows:
SELECT TO_DATE(name,'YYYYMMDD'),
TO_DATE(TRUNC(SYSDATE),'DD-MM-YYYY')
FROM TEST_TABLE
WHERE TO_DATE(name,'YYYYMMDD') < TO_DATE(TRUNC(SYSDATE),'DD-MM-YYYY');
(This is a very simplified example of a problem I'm facing in my partition maintenance script and have not been able to solve for the last week).
Thank you in advance for any assistance related to the above query.
Midnight(time part is 00:00:00.000):
SELECT TO_DATE(name,'YYYYMMDD'), TRUNC(SYSDATE)
FROM TEST_TABLE
WHERE TO_DATE(name,'YYYYMMDD') <= TRUNC(SYSDATE);
You could also try:
ALTER SESSION SET NLS_DATE_FORMAT = 'YYYY-MM-DD HH24:MI:SS';
Just don't apply a to_date() to an already date field, this because, it will implicitly convert that date into varchar and then apply the to_date() function to it, for example your query part TO_DATE(TRUNC(SYSDATE),'DD-MM-YYYY') is interpreted like this:
TO_DATE(TO_CHAR(TRUNC(SYSDATE)),'DD-MM-YYYY')
TO_CHAR(TRUNC(SYSDATE)) is getting a char something like: '31-AUG-17', and that is not in 'DD-MM-YYYY' format.
And because of that, TO_DATE(TRUNC(SYSDATE),'DD-MM-YYYY') gets something like this: 29/09/0017 and your filter goes FALSE and gets no results.
Why does below query work successfully?
select to_char(sysdate,'MM-YYYY') from dual;
But the following queries give an invalid number error:
select to_char('28-JUL-17','MM-YYYY') from dual;
select to_char('7/28/2017','MM-YYYY') from dual;
Though, below query gives you the same date format.
select sysdate from dual; -- 7/28/2017 11:29:01 AM
TO_CHAR function accepts only date or number. Maybe you can try this
select to_char(to_date('28-JUL-17', 'DD-MON-YY'),'MM-YYYY') from dual;
As a side note, if you're planning to convert a bunch of dates to strings so you can look for all records in a certain month of a certain year, be aware that the TRUNC function can be used to reduce the precision of a date (e.g. to "month and year"). The following query pulls all records created this month, from the table. It should be faster than converting dates to char and doing string comparison..
SELECT * FROM table WHERE trunc(create_date, 'MON') = trunc(sysdate, 'MON')
Because function TO_CHAR() accepts date or timestamp values. However, neither '28-JUL-17' nor '7/28/2017' are dates or timestamps - they are STRINGS.
Oracle gently tries to convert these stings into DATE values. This implicit conversion may work or may fail, it depends on your current session NLS_DATE_FORMAT, resp. NLS_TIMESTAMP_FORMAT settings.
As given already in other answers you have to convert the string explicitly:
TO_DATE('28-JUL-17', 'DD-MON-RR')
TO_DATE('7/28/2017', 'MM/DD/YYYY')
to_char() isn't expecting you to start with a char value. If you really want that to work, you'll need to wrap it around a to_date() function.
to_char(
to_date(
'28-JUL-17'
, 'DD-Mon-YY'
)
,'MM-YYYY'
)
You are using an incorrect mask, for more information read here.
The correct one should be:
select to_char(to_date('28-JUL-17','DD-MON-YY'), 'MON-YY') from dual;
You can also extract the month using EXTRACT:
select EXTRACT (MONTH FROM to_date('28-JUL-17','DD-MON-YY')) from dual;

I did the following:
CREATE TABLE BOOK(
BOOK_ID VARCHAR(4) PRIMARY KEY,
ISBN_10 VARCHAR(10),
TITLE VARCHAR(50),
CATEGORY VARCHAR(25),
PRICE DECIMAL(6,2),
BINDING VARCHAR(2),
PUB_DATE DATE,
AUTHOR_ID SMALLINT,
PUBLISHER_ID SMALLINT
);
2.
ALTER SESSION SET nls_date_format = 'DD-MM-YYYY HH24:MI:SS';
3.
INSERT INTO BOOK
VALUES('4','123459','INTRODUCTION TO SmallTalk','IT',157.00,'S',**'26-01-1991'**,13,103);
It gave an error:
ORA-01843: not a valid month
However if do the following there is no problem:
Query:
INSERT INTO
BOOK
VALUES('4','123459','INTRODUCTION TO Small Talk','IT',157.00,'S','**26-JAN-1991**',13,103);
Can anyone explain why?
You want to read the Datetime Literals section of the manual. Alternatives are:
Use a date literal: DATE '1991-01-26'
Convert from string: TO_DATE('26-01-1991', 'DD-MM-YYYY')
If you set NLS_DATE_FORMAT you can omit TO_DATE()'s second argument but not skip the function entirely.
See also: Datetime Format Models
It worked for me. That implies that your alter statement did not work for some reason. However, it is not good practice to assume a specific date format on a system when using literals. Instead, cast the literal with a format mask on the insert, such as:
INSERT INTO BOOK
VALUES('4','123459','INTRODUCTION TO Small Talk','IT',157.00,'S',
to_date('26-JAN-1991','DD-MON-YYYY'), 13,103);
(or whatever format you require as a literal input value)
This because in your database, nls_date_time is set to 'DD-MON-RRRR' format, you can check this using
select * from V$NLS_PARAMETERS
In this query
INSERT INTO BOOK VALUES('4','123459','INTRODUCTION TO SmallTalk','IT',157.00,'S','26-01-1991',13,103);
date format is 'dd-mm-rrrr', change the statement as
INSERT INTO BOOK VALUES('4','123459','INTRODUCTION TO SmallTalk','IT',157.00,'S',to_date('26-01-1991', 'dd-mm-rrrr'),13,103);
and it will also run since you have now provided the date format.
When you set
ALTER SESSION SET nls_date_format = 'DD-MM-YYYY HH24:MI:SS';
then your insert must match this format, i.e.
INSERT INTO BOOK VALUES('4','123459','INTRODUCTION TO SmallTalk','IT',157.00,'S',
'26-01-1991 00:00:00'
,13,103);
However, the more secure way is to use date literals or TO_DATE function.
You just need to use
INSERT INTO TABLE_NAME VALUES('07-JAN-96');
Oracle always takes "DD-MMM-YY" format. You should write your month as the first 3 characters of month name.
I have a field in my table with datatype as DATE in Oracle.
I want to insert the current date into that field, in format DD/MM/YYYY format.
I tried the below query:
select to_date(to_char(sysdate,'dd/mm/yyyy'),'dd/mm/yyyy') from dual
But it gives
1/8/2011 12:00:00 AM.
I want it to insert and show as
08/01/2011 12:00:00 AM.
Can anyone help me in this please ?
DATE is a built-in type in Oracle, which is represented in a fixed way and you have no control over it.
So:
I want it to insert [...] as 08/01/2011 12:00:00 AM
The above is nonsensical. You don't insert a string, you insert a date.
Format is useful only when you want:
to convert a string to an internal representation of date with TO_DATE (format mask: how to parse the string);
to convert an internal representation of date to a string with TO_CHAR (format mask: how to render the date).
So basically, in your example you take a DATE, you convert it to a STRING with some format, and convert it back to DATE with the same format. This is a no-op.
Now, what your client displays: this is because your Oracle Client won't display DATE fields directly and the NLS layer will convert any DATE field that is selected. So it depends on your locale by default.
What you want is SELECT TO_CHAR(SYSDATE,'DD/MM/YYYY') FROM dual; which will explicitly perform the conversion and return a string.
And when you want to insert a date in a database, you can use TO_DATE or date literals.
Alternatively, if you want to retrieve the date part of the DATE field, you may use truncate, i.e.
select to_char(trunc(sysdate),'dd/mm/yyyy') from dual;
When the column is of type DATE, you can use something like:
Insert into your_table(your_date_column) Select TRUNC(SYSDATE) from DUAL;
This removes the time part from SYSDATE.
Maybe this can help
insert into pasok values ('&kode_pasok','&kode_barang','&kode_suplier',
to_date('&tanggal_pasok','dd-mm-yyyy'),&jumlah_pasok);
note: '&' help we to insert data again, insert / end than enter to
insert again example: Enter value for kode_pembelian: BEL-E005 Enter
value for kode_barang: ELK-02 Enter value for kode_customer: B-0001
old 2: '&kode_pembelian','&kode_barang','&kode_customer', new 2:
'BEL-E005','ELK-02','B-0001', Enter value for tanggal_pembelian:
24-06-2002 Enter value for jumlah_pembelian: 2 old 3:
to_date('&tanggal_pembelian','dd-mm-yyyy'),&jumlah_pembelian) new 3:
to_date('24-06-2002','dd-mm-yyyy'),2)
