To_date(to_char(sysdate,'dd/mm/yyyy hh24:mm'),'dd/mm/yyyy hh24:mm')

Hi
I am using this conversion to_date(to_char(sysdate,'dd/mm/yyyy hh24:mm'),'dd/mm/yyyy hh24:mm')
but it says format string appears twice
Could some one please help me with this?

PLease can you suggest anything better than this comparison or let me know if this works correct nowYou are using a TO_CHAR to format a date field in a string. Then use a TO_DATE to change it back to a date. This "double" formatting is a deep misunderstanding about what is a date field.
If you want to compare dates and get rid of the seconds, use truncate, for instance :
SQL> select trunc(sysdate,'mi'),sysdate from dual;
TRUNC(SYSDATE,'MI') SYSDATE
02/02/2010 09:18:00 02/02/2010 09:18:55Your WHERE clause will become :
...trunc(LOAD_DATE,'mi')<(SELECT trunc(CURRLOADTIME,'mi')...Nicolas.

TO_DATE(TO_CHAR(sysdate, 'MM/DD/YYYY'), 'MM/DD/YYYY')

Hi all,
I am working with a Oracle 9i R2 database

SQL>select TO_DATE(TO_CHAR(sysdate, 'MM/DD/YYYY'), 'MM/DD/YYYY') mydate from dual;

I want to retain the 4 digit year. Please suggest what I am doing incorrect.
Thanks

Your select statement,SQL>select TO_DATE(TO_CHAR(sysdate,...is equivalent toselect sysdate...And whenever you select a date, SQL Plus has to convert it to a character format before it can display it on the SQL Plus output screen.
The four-digit year IS being retained internally ...until you display it on the screen. If you just set the default date format for displaying dates to include the four-digit year, you will see the full year:
SQL> select SYSDATE mydate from dual;
MYDATE
14-NOV-05
SQL> alter session set nls_date_format = 'MM/DD/YYYY';
SQL> select SYSDATE mydate from dual;

Difference between storing sysdate and to_date(to_char(sysdate, 'DD Mon YYY

What is the difference between storing sysdate or to_date(to_char(sysdate, 'DD Mon YYYY HH:MI AM'),'DD Mon YYYY HH:MI AM') in a date data type column?
When I column value is set with sysdate the following query gives no records
select *
from Test
WHERE Updatedon = to_date('22 Sep 2012 07:55 PM','DD Mon YYYY HH:MI AM');
when I run the same query with out where clause I am getting the records with that time or storing with to_date(to_char(sysdate, 'DD Mon YYYY HH:MI AM'),'DD Mon YYYY HH:MI AM') gives records.
Can someone explain the difference please?

to_date(to_char(sysdate, 'DD Mon YYYY HH:MI AM'),'DD Mon YYYY HH:MI AM')is equivalent to
TRUNC (SYSDATE, 'MI')To see why, consider what
to_char(sysdate, 'DD Mon YYYY HH:MI AM'),does. It creates a string out of the year, month, day, hours and minutes of SYSDATE, but it ignores the seconds. If you convert that string into a DATE, the seconds will default to 00.
When I column value is set with sysdate the following query gives no records
select *
from Test
WHERE Updatedon = to_date('22 Sep 2012 07:55 PM','DD Mon YYYY HH:MI AM');
when I run the same query with out where clause I am getting the records with that time or storing with to_date(to_char(sysdate, 'DD Mon YYYY HH:MI AM'),'DD Mon YYYY HH:MI AM') gives records.Whenever you get confusing results with DATEs, display the full DATE, including hours, minutes and seconds.
To change the default DATE format in your session, so that the hours, minutes and seconds appear automatically, use ALTER SESSION. For example:
ALTER SESSION SET NLS_DATE_FORMAT = 'DD-Mon-YYYY HH:MI:SS AM';

How can I remove blank space after month value while selecting to_char(sysdate)

select to_char(sysdate,'dd-month-yyyy') from dual;
when I give this query, I'm getting a blank space after the month value. How can I trim that?

Or else try this one
select to_char(sysdate,'dd-fmmonth-yyyy') from dual;
Best of luck.

To_char(adate,'dd.mm.yyyy') returns different results from two oracle clients !!! Is it possible?

Dear all;
We have only one Database server with some IIS's as web servers on front . Each web server has own oracle client software in order connect to central database..
The same following query used in C# code returns different results on each IIS server.(3 row, or not data found )
why?
select * from aTable where to_char( adate , 'dd.mm.yyyy' ) = :search_date

If adate is of DATE datatype, it will most likely has the time component. Therefore your SQL below is unlikely to return any data.

Perhaps.....
select * from aTable where TRUNC(adate) = to_date(:search_date, 'dd.mm.yyyy')
Hi,
not having any sample data from you I could not understand that you wanted to select the range 00:00:00 - 23:59:59 on search_date.
Your method might not be efficient if you have an index on adate.
Maybe something like this will be more efficient
select * from aTable
where adate >= to_date(:search_date, 'dd.mm.yyyy')
and adate < to_date(:search_date, 'dd.mm.yyyy') + 1;
If you search_date is 30-Aug-2013 it will get records where adate >= 30-Aug-2013 00:00:00 and adate < 31-Aug-2013 00:00:00, so any time of date 30-Aug-2013.
Try like this and let us know if you still have 2 different results.

To_date,to_char function behavior

I have a table that contains starting dates of employment for employees. Since the table could have several starting dates (This is normal in our institution), I wrote a pl/sql loop to count the number of employees whose ONLY starting date (meaning they have only one starting date) lies in the year 2008. Now I faced the following problems when running the code in a when-button-pressed trigger in forms:
1. the counter in the statement
if to_char(docexecdt,'dd-mm-yyyy) between '1-1-2008' and '31-12-2008' then x:=x+1
returned an abnormal number (too large for the size of the table)
(where docexecdt is the field containing the starting date)
is using to_char here incorrect?
2. the statement
if to_date(docexecdt) between '1-1-2008' and '31-12-2008' then x:=x+1
returned an error "invalid month"
although I tried several date formats.
given that I tried running the same to_date function on the table in sql*plus with no error returned.
What is the correct format mask for the to_date function?

-> Why does the to_char(docexecdt,'dd-mm-yyyy') return an incorrect result?
Because putting dd (the day of the month) first puts EVERY day between your dates:
01-01-2008 is LESS than ALL the following dates:
01-02-1982
12-01-2000
15-08-1998
30-01-2009
30-12-2020
31-12-2008 is GREATER than ALL the above dates.
NEVER compare dates by placing DAY or MONTH before the year!!!!
When you compare using DDMMYYYY format, the only dates less than 01-01-2008 are January 1 of any prior year. The only dates greater than 31-12-2008 are 31-December of any year greater than 2008.
The correct way to find your count is given by Paul M, where you ONLY look at the year.

Dates are stored and manipulated as coded (binary) values that always contain "century, year, month, date, hour, minute second"
We don't want to see the date as stored. We want to see the characters (digits) that make up the date. So we use to_char(the-date-value)
We want to tell the system a date, but have a heck of a time entering the binary. So we input the characters (digits) that make up the date and tell the system to convert that to a binary 'date' using to_date(our-string-that-respresents-dates)
The magic Oracle has added is the format codes (see chapter 2 of the SQL Reference manual for the complete list). We can get the system to print out dates and times, including day of week (and so on) using format codes.
The default format is to show us the date but not the time. Which leads a lot of people to believe that the time is not stored.

Max(to_char(date,'DD-MM-YYYY')) ?

Hi All,
SQL> desc hday;
Name Null? Type
H_DATE NOT NULL DATE
SQL> select max(h_date) from hday;
MAX(H_DATE

SQL> select max(to_char(h_date,'DD-MM-YY')) from hday;
MAX(TO_C

SQL> select max(to_char(h_date,'DD-MON-YY')) from hday;
MAX(TO_CH
31-MAY-99
My question is why am i getting different dates when i use different date formats in MAX function ?
any ideas ?
greddy

Always compare dates in date format. don't use to_char and then a function on top of it. Use the function on the date type. Also, check this out:
SQL> create table hday(h_date date);
Table created.
SQL> insert into hday values('03-JAN-11');
1 row created.
SQL> insert into hday values('31-MAY-99');
1 row created.
SQL> insert into hday values('31-DEC-99');
1 row created.
SQL> SELECT * FROM HDAY;
H_DATE
03-JAN-11
31-MAY-99
31-DEC-99
SQL> SELECT TO_CHAR(H_DATE, 'DD-MON-YYYY')
2 FROM HDAY;
TO_CHAR(H_D
03-JAN-2011
31-MAY-1999
31-DEC-1999
SQL> SELECT TO_CHAR(H_DATE, 'DD-MON-RRRR')
2 FROM HDAY;
TO_CHAR(H_D
03-JAN-2011
31-MAY-1999
31-DEC-1999
SQL> select max(h_date)
2 from hday;
MAX(H_DAT
03-JAN-11Now this makes a little more sense! In sumary, after y2k oracle recognizes any year before 1950 to be of the 2000's and any year after 1950 to be of the 1900's. For example, 00 is 2000 and not 1900. Also, 51 is 1951 and not 2051. To give you the exact terminology and logic behind I would have to look in the documentation. To avoid this problem, user four digit year when working with dates.
SQL> insert into hday values('03-JAN-1911');
1 row created.
SQL> SELECT TO_CHAR(H_DATE, 'DD-MON-YYYY')
2 FROM HDAY;
TO_CHAR(H_D
03-JAN-2011
31-MAY-1999
31-DEC-1999
03-JAN-1911
SQL> select to_char(min(h_date), 'dd-mon-yyyy') dt
2 from hday
3 union
4 select to_char(max(h_date), 'dd-mon-yyyy') dt
5 from hday;
DT

Sysdate from oracle db in mm/dd/yyyy hh24:mi:ss format

I am trying to get sysdate from oracle db in mm/dd/yyyy hh24:mi:ss format but the result it gives back is 00:00:00 for hh24:mi:ss.
code:
try
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection( connStr, userName, passWord );
PreparedStatement pstmtQuery = con.prepareStatement(" SELECT to_date(to_char(sysdate,'mm/dd/yyyy hh24:mi:ss'), 'mm/dd/yyyy hh24:mi:ss') SYS_DATE FROM DUAL" );
ResultSet rsQuery = pstmtQuery.executeQuery();
DateFormat localFormat1 = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
java.sql.Date date3 = null;
if(rsQuery.next())
date3 = rsQuery.getDate("SYS_DATE");
System.out.println("\ndatabase sysdate: " + localFormat1.format( date3 ));
catch (SQLException sqle)
sqle.printStackTrace();
catch (java.lang.Exception e)
e.printStackTrace();
}

When you use the to_date function, the result you get back will be in the default date format as specified by the nls_date_format property. The data is stored properly (i.e., it includes the time values), but when it's displayed it's displayed in the standard format. So even if the datetime is 10/11/2001 10:12:35, the value that will be displayed when you select sysdate will be 11-OCT-01 if you're using the default date format of DD-MON-YY.
Are you sure that your statement is returning the desired string when you type it directly into SQL? If so, then I have to guess that your default date format is set up the way you want it when you go into SQL directly, but that a different default date format is used when you're executing the statement via jdbc.
I've never tried setting the default date format through jdbc, so I don't know if it will work, but the way to set the format is to alter the session:
alter session set nls_date_format = 'mm/dd/yyyy hh24:mi:ss';

ORA-20001 When trying to default page element to sysdate

Hello,
I have a master detail with last updated in the detail that I want to autopopulate based on sysdate.
To do that I have Tabular Form Attributes set to sysdate and default type PL/SQL Expression or function.
The display as is set to "Display as Text(saves state).
I would like to format the date which I do with Column Attributes and then specify the Number Data Format.
When I click add row in the detai part of the pagethe date is displayed as desired however then I try and
apply the changes (save the page) I get ORA-20001: Found invalid date value, please verify date format. (Row 2)
I have tried formatting the date in the PL/SQL expression with TO_DATE(SYSDATE,'DD-MON-YYYY HH24:MI')
with the same result.
If I change the element to Text Field the date is saved correctly however I don't want the user to edit the
feild.
Any suggestions? Using APEX 4.1

I have the same issue.
1. DEFAULT=SYSDATE when using format mask='DD-MON-YYYY HH24:MI:SS' causes the time portion to appear but ORA-20001 when submitting the row.
2. Since the base column datatype is DATE, a simple to_char(SYSDATE,'DD-MON-YYYY HH24:MI:SS') obviously causes ORA-01790: expression must have same datatype as corresponding expression.
3. A to_date(to_char(SYSDATE,'DD-MON-YYYY HH24:MI:SS'),'DD-MON-YYYY HH24:MI:SS') leads to the same error: ORA-20001: Found invalid date value, please verify date format.
Does anyone know the trick?

Defaulting sysdate on save - no time component

I have a date column (date_modified) in my table and i am displaying on form as date picker DD-MON-YYYY HH:MI. Users can not enter this but they can see it. When I save the record I have am setting the item like P1_DATE_MODIFIED := sysdate; and then the automatic update process puts it in. trouble is, it is going in without the time component. I have tried P1_DATE_MODIFIED := to_date(to_char(sysdate,'dd-mon-yyyy hh24:mi'),'dd-mon-yyyy hh24:mi'); but no luck there either. if i update the column in sqlplus using the sysdate or to_char to_date method then it does get the time component and it displays it in my form. I cant figure out why it loses it when inserting when the last thing i do before insert is convert it to the time format (i shouldn't even need to do that, sysdate should work fine)

Hi Victorp or any others,
I am also having a major problem of not able to store time component. I have a field called ":P61_WHEN_CREATED" in my form DISPLAY aS (Date Picker DD-MON-YYYY HH24:MI) and I have a process after submit - Before computations and validations) to set the field value to sysdate as :
:P61_WHEN_CREATED := to_char(sysdate,'DD-MON-YYYY HH24:MI');
and after submit after computations and validations I have another process to post the values into table as:
Insert into c_addendums (MECnum,WHEN_CREATED) values :P61_MECNUM, :P61_WHEN_CREATED;
But i am getting the error :
ORA-01830 date format picture ends before converting entire input string.
Can you please help me.

How to convert character value to_date?

I want to change the time (hours) in sysdate to '10' and then save this new date into a date column for that i've written the following command
(TO_CHAR(SYSDATE,'DD-MON-RRRR')||' 10:'||TO_CHAR(SYSDATE,'MI:SS AM'))this command will remove the actual hours in sysdate and change it with the value '10'. but the result of this command is a character value. and i want a date value to insert into a date column. for that i've converted this command to_date as follows
TO_DATE(TO_CHAR(SYSDATE,'DD-MON-RRRR')||' 10:'||TO_CHAR(SYSDATE,'MI:SS AM'))but it gives the following error
ORA-01830: date format picture ends before converting entire input string
