Converting a character string to into a date raise ORA-01843

I always confused in using to_date() function,such as the following example.How could I convert the string "'8-十月-2006 " into a date correctly.Thank you in advance.
SQL> select TO_DATE('18-十月-2006 16:49:57','dd-mon-yyyy hh24:mi:ss','nls_DATE_language=''SIMPLIFIED CHINESE''') from dual;
select TO_DATE('18-十月-2006 16:49:57','dd-mon-yyyy hh24:mi:ss','nls_DATE_language=''SIMPLIFIED CHINESE''') from dual
ORA-01843: not a valid month

Hello:
I suppose you have a bad Oracle-client enviroment. If you note, you can't see a valid month, in place you are seeeing tho characters: '??'. This often indicates that you Oracle client settings (like NLS_LANG, NLS_DATE, etc.) are bad and you are not cappable to do some translation to see it.
Try if you can see another data from your database in Chinesse format, because also is possible that enviroment of your Oracle server is badly configured (like lang variables).

Date error ORA-01843: not a valid month

Hi,
I am in a 4.01 Apex environment with NLS_DATE_FORMAT mm/dd/yyyy. I created a view with a CASE statements using 'when eventstartdate between '08/15/2010' and '06/1/2011' then...' clauses and the view is created fine. I also can query the view with no problem with SQL workshop and the CASE statements work as expected. When I create an interactive report on that view I keep getting ORA-01843: not a valid month. I even tried matching the format in the Interactive Report column format mask to the NLS format for the date and still get error.
What seems especially strange to me is that even if I have the view column defined with a 'to_char' I still get the same error when I use the CASE statement to build the view. Doesn't the Interactive Report just 'see' the View column definitions-- why should it 'care' how the view was built?
The only way I can get the View to work with an Interactive report in any manner is to remove all the CASE statements and define the 'eventstartdate' as text using to_char but that then eliminates my ability to do any filters that require date comparisons with between or '>', '<'.
Help would be appreciated!
Thanks,
Pat

Quick late night response - always convert your dates for comparison. Apples to apples
Instead of between '01/31/2012', use either
TO_DATE('01/31/2012', 'MM/DD/YYYY')or
DATE '2012-01-31'More related info

You can search the forums for that error message and find previous discussions - they all boil down to the same problem. Somewhere in your query that calls this function, the code invoked implicitly converts from string to date/datetime. In general,
this works in any version of sql server if the runtime settings are correct for the format of the string data. The fact that it works in one server and not in another server suggests that the query executes with different settings - and I'll assume for
the moment that the format of the data involved in this conversion is consistent within the database/resultset and consistent between the 2 servers.
I suggest you read Tibor's guide to the datetime datatype (via the link to his site below) first - then go find the actual code that performs this conversion. It may not be in the function you posted, since that function also executes other functions.
You also did not post the query that calls this function, so this function may not, in fact, be the source of the problem at all.

[Oracle 8i] How to convert a string (time stamp) into a date?

I'm having difficulty figuring out how to convert a time stamp string into a date (or possibly a number).
The time stamp is 20 positions, character (NOT NULL, CHAR(20))
in the format: YYYYMMDDHHMMSSUUUUUU
where Y = Year, M = Month, D = Day, M = Minutes, S = Seconds, and U = Microseconds
The reason I want to convert this is so that I can compare one time stamp to another (i.e. I want to be able to find the MIN(timestamp), MAX(timestamp), and do inequality comparisons).
Is this at all possible?
Thanks in advance for help on this!

Hi,
As Damorgan said, if all you want to do is find which is the earliest or latest, then you can just compare the strings: they happen to be in a format where that works.
If you need to do other things, such as compare them to today's date, or see the difference between two of your rows in days, then you have to convert them to DATEs. (There's no point in converting them to NUMBERs).
A new data type, TIMESTAMP, which handles fractions of a second, was introduced in Oracle 9.
Since you're using Oracle 8 (according to your subject line), you either have to
(1) ignore the microseconds, or
(2) use a separate NUMBER column for the microseconds.
Either way, use TO_DATE to convert the first 14 characters to a DATE:
TO_DATE ( SUBSTR (txt, 1, 14)
, 'YYYYMMDDHH24MISS'
)where txt is your CHAR column.
To convert the microseconds to a number (between 0 and 999999):
TO_NUMBER (SUBSTR (txt, 15))

Hi,
The above error appears due to date format is differnt from SAP query generator and SQL server.
So you need convert all date in above query to SQL server required format.
Try to convert..let me know if not possible.

Converting a string into mySQL date format

I have a bit of code that collects data values from a bean and I want it to then insert this into a mySQL database. My string is in the format "23/12/1983", how can i put this into a date field in my database? The bit of code I have got so far looks like this...
String month = formHandler.month + "/";
String day = formHandler.day + "/";
String year = formHandler.year ;
StringBuffer sb = new StringBuffer();
sb.append(day);
sb.append(month);
sb.append(year);
String myDate = sb.toString();myDate is the value that I want to go into the database

Limo2kz,
The key to inserting a date into a database is to convert the date string into an SQL friendly format. i.e. yyyy-MM-dd.
One way of doing this is as follows:
SimpleDateFormat NICE_DATE_FORMAT =
new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat SQL_DATE_FORMAT =
new SimpleDateFormat("yyyy-MM-dd");
Date date = new Date();
try {
date = NICE_DATE_FORMAT.parse(dateString);
} catch (ParseException pe) {
pe.printStackTrace();
String sqlDate = SQL_DATE_FORMAT.format(date);
Now it is just a matter of creating the insert statement like normal, and making sure that the date string is in quotes.
I hope that helps.

Convert a string in dd/mm/yy form into a date in mm/dd/yy form

hi everyone
am having a problem.
i have a jsp page which receives a "request.getParameter("date")"
My user has input this date in the format dd/mm/yy
but i need to output this date to my db which accepts mm/dd/yy format.
Am thinking of implementing this in the follwing way
1:Since i have a string in dd/mm/yy form,i parse it to a date in this very format.
2:then i format it again to the mm/dd/yy form
3: i output it to the db
is this the correct way of doing it?
is there an easier way to convert a string in dd/mm/yy form directly into a date in mm/dd/yy form without getting a distorted value?
help me please

Hi,
Parsing the date manually is a tedious task. If performance is not a issue, it is better to use SimpleDataFormat. Here is a sample code for converting the format:
String str = "01/02/1999";
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date dt = sdf.parse(str);
sdf.applyPattern("MM/dd/yyyy");
System.out.println(sdf.format(dt));

.net program also using same algorithm to encrypt this password.....finally both the character strings are not equel.(This happens if the character string's ascii value greater than 127. otherwise both are equel).
pls give me a solution for this
thanks and regards

Date time characteristic converted in a string in Universe OLAP

Hi there,
We are facing to the following issue. Maybe one of you has been already facing to.
We have created a BO universe on top of BI queries (based on MDX) and we make WEBI reports.
We note when we update/refresh the OLAP structure, all characteristics (Number and date) are converted/considered as a character and string and we loose in that way the time information.
This is very ennoying when sorting on time dimensions as WEBI can only sort on Alphabetic order.
Indeed, we would like to display the last 13 month of a key figure as from the last month.
As the time characteristic is automatically converted by the Olap refresh structure in a string, we can't display the last 13 months in logical/natural/calendar order.
Ex: NOV 2007 | DEC 2007 | JAN 2008 | FEB 2008 ....DEC 2008
Any idea :
- why the 'Refresh structure' command automatically convert into a string?
- how to force him not to convert to string and keep the date information?
- order date as the logical/natural/calendar one?
Beforehand, thanks a lot

Hi Ingo,
I'm using 0CMonth or 0CALMONTH which are SAP characteristics.
Do you know how to sort data by date and not by string?
When we recuperate infoobejcts from BI queriies, all objects are string and all LOV are sorted by string which don't help us.
imagine we have JAN 1996, JAN 1997,... FEB 1996 etc etc.

Convert a date in String format to a Date

Hi,
How can I convert a date in String format to a Date object?
I have tried:
import java.text.*;
import java.io.*;
import java.util.Date;
import java.util.Locale;
import java.sql.*;
public class casa {
public static Connection con = null;
public static Statement s = null;
public static String sql = null;
public static String mydate = "01.01.2001";
/** Creates a new instance of casa */
public casa() {
public static void main(String[] args) throws SQLException{
try {
DateFormat shortFormat = DateFormat.getDateInstance(DateFormat.SHORT);
Date date = shortFormat.parse(mydate);
//Open Database
con = getConnection();
s = con.createStatement();
sql = "select date1 from table1 where date1 <= '"+date+"'";
ResultSet rs = s.executeQuery(sql);
while(rs.next()){
String aba = rs.getString("datum");
System.out.println("New Datum = "+aba);
} catch (Exception ex ) {
ex.printStackTrace();
closeConnection(s, con);
//Connection
private static Connection getConnection() {
Connection con = null;
String user ="aouzi";
String passe ="aouzi";
String url = "jdbc:db2:EjbTest";
try {
//Datenbanktreiber laden
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
//Verbindung herstellen
con = DriverManager.getConnection(url,user,passe);
}catch(ClassNotFoundException e){
} catch(SQLException e){}
return con;
//close Connection
private static void closeConnection(Statement s, Connection con) {
try {
s.close();
} catch (SQLException e) {}
try {
con.close();
} catch (SQLException e) {}
I'm getting the following errors:
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0180N
The syntax of the representation of a date/time of day value as character sequence is false. .SQLSTATE=22007

I'm pretty sure it won't understand what date.toString() returns. If you know what format the database understands, you do it like this:
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yy"); // e.g. 18-Apr-02
String datestring = sdf.parse(date);
and use that instead of date in your sql string. Some databases understands it if you do
"to_date('18-Apr-02')"
so you could include that in your sql string as well..
You could also try to make it a java.sql.Date and hope your jdbc driver knows how to convert it to a string that the database understands if you don't know the format:
con = getConnection();
PreparedStatement ps = con.prepareStatement("select date1 from table1 where date1 <= ?");
ps.setDate(new java.sql.Date(date.getTime()));
ResultSet rs = s.executeQuery(sql);

Converting a character string to into a date raise ORA-01843
