String into java.sql.Date

Can anyone tell me how to convert a String
(yyyy-mm-dd) into a java.sql.Date format? Also I need
to test to see if the Date of birth (entered in the
format above) is >= 18.
Can I do this in an SQL query?
Thanks
Marika LudmannTry this:
   String dateStr = "2003-04-29";
   SimpleDateFormat formater = new SimpleDateFormat("yyyy-MM-dd");
   Date result = formater.parse(dateStr);Don't forget to add the
import java.text.SimpleDateFormat;

Convert string into java.sql.Date

Hi,
I want to convert a date in string form into java.sql.Date to persist into the database column with Date as its datatype in Oracle. I'm trying as follows:
import java.sql.Date;
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class DateTest
public static void main(String[] args)
String strDate = "2002-07-16 14:45:01";
     System.out.println("strDate = "+strDate);
Date aDate = null;
try
if(strDate != null && !strDate.trim().equals(""))
     SimpleDateFormat aSDF = new SimpleDateFormat();
     aSDF.applyPattern("yyyy-MM-dd hh:mm:ss");
     java.util.Date utilDate = aSDF.parse(strDate);
System.out.println("utildate = "+utilDate);
     aDate = new Date(utilDate.getTime());
     aDate.setTime(utilDate.getTime());
     System.out.println("aDate = "+aDate);
catch (ParseException e)
System.out.println("Unable to parse the date - "+strDate);
catch (Exception ex)
ex.printStackTrace();
System.out.println("Caught Exception :"+ex.getMessage());
It gives the output as :
strDate = 2002-07-16 14:45:01
utildate = Tue Jul 16 14:45:01 IST 2002
aDate = 2002-07-16
If I put this value into the database table, I can see only the date. Time part is missing. Is this the problem with java.sql.Date or Oracle datatype Date? Please help me asap.
Thanks in advance.

problem with java.sql.Date or Oracle datatype Date?This is not a problem, this is the defined behaviour of the Date type. RTFAPI and have a look at Timestamp, while you're at it.

Convert a string to JAva.sql.date..

I am having a string with the value as follows..
String fval="03-10-2001"..
I am using this value in a rs.updateDate method where I need to convert it to a different format as
2001-10-03...can anybody give me the syntax..

You should hold dates as Date instances. But if you want to convert between Strings and Dates then you should use a DateFormat:
String originalDateString = "31-10-2001";
// Convert the original string to a date
DateFormat originalDateFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = originalDateFormat.parse(originalDateString);
// Get a representation of the date in the new format
DateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd");
String newDateString = newDateFormat.format(date);(Excuse the quirky formatting that the Java code filter applies!)
Hope this helps.

How do I create a Dynamic java.sql.Date ArrayList or Collection?

I Have a MySQL table with a Datetime field with many values inserted.
I want to know which is the Best way to capture all the Inserted DB values inside a Dynamic Array.
I get errors that state that I should use Matching data-types, and plus I don't know how to create or fill a Dynamic Date ArrayList/Collection.
Please Help, I need this urgently...

I have like 25 records in that Database table, but they will grow, so I would really appreciate to know the code to do this. I suspect my problem is in the bolded part of my code.
Thank you very much Sir.

How to change a date value from "java.util.Date" to "java.sql.Date"?

but when i show it to screen, i want to show it as dd-MM-yyyy
I m using the following to change the jave.util.Date to str and vice versa. But it cannot shows the dd-MM-yyyy. I tried to change the format from yyyy-MM-dd to dd-MM-yyyy, it shows the wrong date in my application.
     public String date2str(java.util.Date thisdate)     {

JTextfield input Date convert to java.sql.Date

Hi. I have a textfield for users to input date in 'dd/mm/yyyy' format and I would like to format this input into java.sql.Date to be stored into a database. How should I go about doing that ?
I did the following:
SimpleDateFormat formatDate = new SimpleDateFormat("dd/mm/yyyy");
java.util.Date invoiceDate = formatDate.parse(jTextField3.getText());
java.sql.Date sqlDate = new java.sql.Date(invoiceDate.getTime());and when I input into jTextField3 the value '28/05/2008' , I found in my database '2008-01-28'. January and May is a few months off and is totally not what I wanted.

Hi you did you code perfect, but you need to change the pattern for formatting the Date
dd - date
mm - minute
yyyy - year
here you are parsing month as minute, so the output may wrong..!
If you need to format properly
please use the below pattern
{color:#0000ff}SimpleDateFormat formatDate = new SimpleDateFormat("dd/MM/yyyy");{color}

How to convert JAVA.SQL.DATE date in YYYY/MM/DD format into DD/MM/YYYY

i am using informix database which accepts date value in the form of DATE format......
the other part of my application takes date from the field in DD/MM/YYYY format...so i have to convert my java.sql.date in YYYY/MM/DD fromat into DD/MM/YYYY fromat of same type before inserting into db......
but using parse method in SimpleDateFormat class can get the result only in java.util.date format...
and also using format method can result only in string conversion........

Maybe you mean Informix (fronted by JDBC) expects date values as java.sql.Date objects?
the other part of my application takes date from the field in DD/MM/YYYY format...
so i have to convert my java.sql.date in YYYY/MM/DD format into DD/MM/YYYY format of same type before inserting into db......I am not sure why you are talking about formats here.
There is no formatting inherent in a java.util.Date object
nor in a java.sql.Date object.
but using parse method in SimpleDateFormat class can get the result only in java.util.date format...
and also using format method can result only in string conversion........You can easily create a java.sql.Date object from a java.util.Date object.
String s = "31/12/2010";
java.util.Date ud = new java.text.SimpleDateFormat("dd/MM/yyyy").parse(s);
java.sql.Date sd = new java.sql.Date(ud.getTime());
ud = sd; // java.sql.Date extends java.util.Date so no conversion is needed

Converting String foramt(yyyy-mm-dd) to java.sql.Date format(mm/dd/yyyy)

Hi,
I am new to this Technology.
in my Project DataBase I have the date field as String in format yyyy-mm-dd. when I am trying to fetch this date through the front-end I need to see the date in dd/mm/yyyy format of type java.sql.Date Variable.
if you know, Pl help me.
Thanks in Advance,
Kamala.

Then use a SimpleDateFormat object to parse it into a Date object, and also to format the Date the way you want to see it, rather than simply relying on the toString() implementation.

How to convert String date to java sql date

Convert String to java UTC date then to sql date

Hi,
I am trying to convert string (MM/dd/yyyy format) to UTC date time and store in the database.
This is what I did:
String dateAsString = "10/01/2007";
SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
formatter.setTimeZone(TimeZone.getTimeZone("GMT"));
formatter.setLenient(false);
java.util.date dateValue = formatter.parse(dateAsString, new ParsePosition(0));
dateValue will be Sun Sep 30 20:00:00 EDT 2007 in UTC.
Now I need to store this date and time to MS SQL database.
I used the following code:
java.sql.Date sqlDateValue = new java.sql.Date(parsedToDate.getTime());
But this code give only the date, not time 2007-09-30
Can anybody tell me how I can change this java date to sql date (or datetime?) so that I can get both date and time.
Thanks,
semaj

Problem Writing java.sql.Date to MS Access

I have a relatively simple application that is for my own use (not distributed on an enterprise-wide basis). As I don't have an IT staff, I'm using a rudimentary Java front-end (v1.3.1) and a Microsoft Access backend.
I seem to have trouble using INSERT/UPDATE statements with the MS Access Date/Time data type. Below is an example of code being used (id is defined as Text, amount is a Number and timestamp is Date/Time):
conn = DriverManager.getConnection("jdbc:odbc:markets", "", "");
conn.setAutoCommit(true);
String sql = "INSERT INTO temp (id, amount, timestamp) VALUES (?, ?, ?)";
PreparedStatement stmt = conn.prepareStatement(sql);
String id = args[0];
int len = id.length();
java.sql.Date dt = new java.sql.Date(new java.util.Date().getTime());
stmt.setString(1, id);
stmt.setDouble(2, id.length());
// I think the problem is here - the JDBC driver doesn't properly map dates to Access???
stmt.setDate(3, dt);
stmt.execute();
stmt.close();
conn.close();And I get the following error:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access
Driver] Syntax error in INSERT INTO statement.
        at sun.jdbc.odbc.JdbcOdbc.createSQLException (JdbcOdbc.java:6879)
        at sun.jdbc.odbc.JdbcOdbc.standardError (JdbcOdbc.java:7036)

        at sun.jdbc.odbc.JdbcOdbcStatement.execute (JdbcOdbcStatement.java:338)
        at TestWritingDate.main(TestWritingDate.java:31) I'm virtually certain this is a translation problem with
the java.sql.Date and the JDBC driver. But I can't seem
to overcome this. Any help is DESPERATELY needed.
Thanks.
Matt

That was it....thanks...didn't even consider that....perhaps I should start using class names that are already in use too :-). Thanks again...
