SQL-Date before 1970?

Hi,
How can i store Date-Objects past 1970?
The Date or Timestamp-constructor don't support this.
Is there any solution instead of storing the date as a string?
Regards

I think you can do this passing negative values to the constructor of Date, Timestamp classes that accept a long argument.
You can use SimpleDateFormat to parse string dates with predefined formats to get date (java.util.Date) objects. And then you can use those date objects to obtain java.sql.Date / timestamp objects.

Java.sql.Date vs java.util.Date vs. java.util.Calendar

All I want to do is create a java.sql.Date subclass which has the Date(String) constructor, some checks for values and a few other additional methods and that avoids deprecation warnings/errors.
I am trying to write a wrapper for the java.sql.Date class that would allow a user to create a Date object using the methods:
Date date1 = new Date(2003, 10, 7);ORDate date2 = new Date("2003-10-07");I am creating classes that mimic MySQL (and eventually other databases) column types in order to allow for data checking since MySQL does not force checks or throw errors as, say, Oracle can be set up to do. All the types EXCEPT the Date, Datetime, Timestamp and Time types for MySQL map nicely to and from java.sql.* objects through wrappers of one sort or another.
Unfortunately, java.sql.Date, java.sql.Timestamp, java.sql.Time are not so friendly and very confusing.
One of my problems is that new java.sql.Date(int,int,int); and new java.util.Date(int,int,int); are both deprecated, so if I use them, I get deprecation warnings (errors) on compile.
Example:
public class Date extends java.sql.Date implements RangedColumn {
public static final String RANGE = "FROM '1000-01-01' to '8099-12-31'";
public static final String TYPE = "DATE";
   * Minimum date allowed by <strong>MySQL</strong>. NOTE: This is a MySQL
   * limitation. Java allows dates from '0000-01-01' while MySQL only supports
   * dates from '1000-01-01'.
public static final Date MIN_DATE = new Date(1000 + 1900,1,1);
   * Maximum date allowed by <strong>Java</strong>. NOTE: This is a Java limitation, not a MySQL
   * limitation. MySQL allows dates up to '9999-12-31' while Java only supports
   * dates to '8099-12-31'.
public static final Date MAX_DATE = new Date(8099 + 1900,12,31);
protected int _precision = 0;
private java.sql.Date _date = null;
public Date(int year, int month, int date) {
    // Deprecated, so I get deprecation warnings from the next line:
    super(year,month,date);
    if(! isWithinRange(this))
      throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public Date(String s) {
    super(0l);
    // Start Cut-and-paste from java.sql.Date.valueOf(String s)
    int year;
    int month;
    int day;
    int firstDash;
    int secondDash;
    if (s == null) throw new java.lang.IllegalArgumentException();
    firstDash = s.indexOf('-');
    secondDash = s.indexOf('-', firstDash+1);
    if ((firstDash > 0) & (secondDash > 0) & (secondDash < s.length()-1)) {
      year = Integer.parseInt(s.substring(0, firstDash)) - 1900;
      month = Integer.parseInt(s.substring(firstDash+1, secondDash)) - 1;
      day = Integer.parseInt(s.substring(secondDash+1));
    } else {
      throw new java.lang.IllegalArgumentException();
    // End Cut-and-paste from java.sql.Date.valueOf(String s)
    // Next three lines are deprecated, causing warnings.
    this.setYear(year);
    this.setMonth(month);
    this.setDate(day);
    if(! isWithinRange(this))
      throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public static boolean isWithinRange(Date date) {
    if(date.before(MIN_DATE))
      return false;
    if(date.after(MAX_DATE))
      return false;
    return true;
public String getRange() { return RANGE; }
public int getPrecision() { return _precision; }
public String getType() { return TYPE; }
}This works well, but it's deprecated. I don't see how I can use a java.util.Calendar object in stead without either essentially re-writing java.sql.Date almost entirely or losing the ability to be able to use java.sql.PreparedStatement.get[set]Date(int pos, java.sql.Date date);
So at this point, I am at a loss.
The deprecation documentation for constructor new Date(int,int,int)says "instead use the constructor Date(long date)", which I can't do unless I do a bunch of expensive String -> [Calendar/Date] -> Milliseconds conversions, and then I can't use "super()", so I'm back to re-writing the class again.
I can't use setters like java.sql.Date.setYear(int) or java.util.setMonth(int) because they are deprecated too: "replaced by Calendar.set(Calendar.DAY_OF_MONTH, int date)". Well GREAT, I can't go from a Date object to a Calendar object, so how am I supposed to use the "Calendar.set(...)" method!?!? From where I'm sitting, this whole Date deprecation thing seems like a step backward not forward, especially in the java.sql.* realm.
To prove my point, the non-deprecated method java.sql.Date.valueOf(String) USES the DEPRECATED constructor java.util.Date(int,int,int).
So, how do I create a java.sql.Date subclass which has the Date(String) constructor that avoids deprecation warnings/errors?
That's all I really want.
HELP!

I appreciate your help, but what I was hoping to accomplish was to have two constructors for my java.sql.Date subclass, one that took (int,int,int) and one that took ("yyyy-MM-dd"). From what I gather from your answers, you don't think it's possible. I would have to have a static instantiator method like:public static java.sql.Date createDate (int year, int month, int date) { ... } OR public static java.sql.Date createDate (String dateString) { ... }Is that correct?
If it is, I have to go back to the drawing board since it breaks my constructor paradigm for all of my 20 or so other MySQL column objects and, well, that's not acceptable, so I might just keep my deprecations for now.

Date - before and after precision?

Hi all,
I have two date objects and I am using the before and after methods for a decision process. I would like to know the precision of the above methods. Is the prevision at the seconds, milliseconds, or nanoseconds level?
Any help is appreciated.
Thanks
Saravanan

What does this have to do with JDBC?
java.util.Date uses milliseconds.
java.sql.Data uses nanoseconds (which isn't going to matter unless something actually sets those.)

TS3579 I found this useful because I did not know about the effect of typing in data and that you could only drag to rearrange the data. I had typed in data before and this had caused problems but restoring defaults did not cause correct dates to show up

I found this (TS3579: If the wrong date or time is displayed in some apps on your Mac Learn about If the wrong date or time is displayed in some apps on your Mac) useful because I did not know about the effect of typing in data and that you could only drag to rearrange the data. I had typed in data before and this had caused problems but restoring defaults did not cause correct dates to show up in Finder.

It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

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

SQL Data Sync - column type invalid for use as a key column

Hello,
our sync group is failing to do the sync. Here's a tracingID:
For more information, provide tracing ID ‘e3e568b5-140a-4ae5-a4c8-c178c6bf805d’ to customer support.
I must say, that the column in DB is not a PK or INDEX-ed, it was initially VARCHAR(MAX), after some reading I changed it to VARCHAR(200) and later to TEXT, but the result of syncing is still the same.
Thank you,
Bojan

Hi Bojan,
The error “column type invalid for use as a key column” could be due to the existence of unsupported data types or column properties when implementing the synchronization. I recommend you check your database according to this article:
SQL Database Data Types supported by SQL Data Sync.
Besides, before you design and implement a data synchronization plan, please check the following articles about system requirements for SQL Data Sync and so on.

Java.sql.Date and java.util.Date - class loaded first in the classpath

I had two jar files which has java.util.Date and java.sql.Date class file. i want to know whether which class is loaded first in the classpath...
I like to change the order of loading the class at runtime...
Is there is any way to change the order of loading of class...
I may have different version of jar files for example xerces,xercesImpl. some of the code uses xerces ,some of the code uses xercesImpl..i had common classes.
I like to load the class with the same name according to the order i need..
Can we do all these in Run time ?????

The classes you are referring to are part of the Java API. Third party jars have no impact on that. And you can't change to the order because java.sql.Data is derived from java.util.Date. So the second must load before the first.
And if you have two jar files with those classes in them (and not classes that use them) then you either should already know how to use them or you should stop trying to do whatever you are doing because it isn't going to work.

Sql.Date problem

Hi,
I am using java.sql.Date and preparedStatement for SQL select query, something like
: select app_id, entry_date, message from testTable where entryDate >= ? and entryDate <= ?
for example i'am supplying date as yesturday's date and i want data where
say: 24-Oct-2005 12:00:00AM to 24-Oct-2005 11:59:59PM, basically whole days data.
<code>
SimpleDateFormat formatter =
new SimpleDateFormat("dd-MMM-yyyy", Locale.US);
SimpleDateFormat formatter1 =
new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss aaa", Locale.US);
String new1 = formatter1.format(formatter.parse(dateStr));
System.out.println("new1 : "+ new1);
Date date = new Date(formatter1.parse(new1).getTime());
long nextDate = date.getTime()+(23*60*60*1000);
System.out.println("d: " + date);
System.out.println("next: " + new Date(nextDate));
</code>
problem is this code giving me same outputs, whereas, i need to supply, different timings to the same date.
Thanks to anyone who can help me.

I think the easier way is to use Calendar.getInstance() to return a Calendar instance and then use the various set() methods to set the time to midnight or the second before midnight of the next day.
See the API docs for java.util.Calendar.

My database not listed at SQL data source in Web Expression 4

Can anyone help me out?
Am not sure whether this is the correct place for my problem.
I set up SQL Server 2005. Created a database named "employee" and a table under it "emp_info"
I tried to connect it from Microsoft Web Expression 4 through SQL Data Source control. Well, the connection test is successful but the database i created is not shown in the drop down. However, it shows the system databases.
Again i create the table under one of the system databases, and tried to connect it. Those system tables which are there from before are only available to connect but not the table i newly created.
I have checked the properties, permission of the table as well as the database. Nothing is wrong there.
Will attach screenshot after the forum admin verify me.

EJB/SQL data type mapping

Is there a way to define the mapping between SQL data types and the generated Entity bean data types.
(SQL server tiny int is getting mapped to a boolean!!! so I want to change it to a small, is there anything in the EJB 2.0 specification that defines the mapping between DB and EJB types).
thx,
sanjay.

I haven't done any bottom up beans but I would imagine there is an equivalent way you can change the mapping to change the data type when the bean is created. You may just have to change the datatype on the imported db schema before you generate the beans. You will also need to check that your jdbc driver supports transformation between tinyint and small.

(Again) java.util.Date vs java.sql.Date

Hi there,
(Again) Im trying to understand the EXACT difference between
java.util.Date vs java.sql.Date.
Googling, I can see that this is a very "popular" subject, but I still
cannot figure out it exactly.
Many writers claim that java.sql.Date only stores the DATE part (yyyy-
mm-dd) but not the TIME part (hh:MM:ss) of a Date/Time value, but that
I can easily disprove:
java.util.Date ud = new java.util.Date(); java.sql.Date sd = new java.sql.Date(ud.getTime()); System.out.println(DateFormatUtils. format(ud, "yyyy-MM-dd HH:mm:ss.SSS")); System.out.println(DateFormatUtils. format(sd, "yyyy-MM-dd HH:mm:ss.SSS"));
Output:
2009-09-18 15:17:36.635 2009-09-18 15:17:36.635
So, apparently, java.sql.Date and java.util.Date have THE SAME
precision (at least down to the millisecs...).
And the official API documentation, really looks more confusing than
helpful to me::
*"java.sql.Date:*
*A thin wrapper around a millisecond value that allows JDBC to identify*
*this as an SQL DATE value. A milliseconds value represents the*
*number of milliseconds that have passed since January 1, 1970*
*00:00:00.000 GMT.*
*To conform with the definition of SQL DATE, the millisecond values*
*wrapped by a java.sql.Date instance must be 'normalized' by setting*
*the hours, minutes, seconds, and milliseconds to zero in the*
*particular time zone with which the instance is associated. "*
Exactly what means "an SQL DATE value" ? How EXACTLY does it differ
from a java.util.Date value?
Most importantly: WHY does JDBC need to distinguish between them?
And, here again: *"a java.sql.Date instance must be 'normalized' by*
*setting the hours, minutes, seconds, and milliseconds to zero in the*
*particular time zone..."*
What does that mean exactly? Apparently, the constructor doesnt
enforce this restriction, per the example above. So what's the REAL
point with this type, java.sql.Date?
Very greatful, if you can help me clarify this, once and for all.
TIA,

And the official API documentation, really looks more confusing than helpful to me:The problem is that you need to understand SQL as well as Java for this to make sense. It's not the Java API's job to tell you how your SQL database works - there's a myriad of subtle differences even when the DB is compliant with the SQL spec.
Most compliant databases support DATE, TIME, and TIMESTAMP values. DATE represents only a date. TIME represents only a time. TIMESTAMP represents both. There are further complicating factors, but that's roughly how it stands.
In Java the normal type for representing time is (or was when the API was created) the java.util.Date but this is a close approximation only to the TIMESTAMP value. In order to bring the two together the java.sql.Date, java.sql.Time and java.sql.Timestamp classes were created. Making them derive from java.util.Date was probably not a good idea.
java.util.Date suffers from a number of deficiencies. java.util.Calendar was supposed to address them but didn't really succeed. The JodaTime library is rather better, but it's all a lot more complicated than you might expect - partly because time management really is a much harder problem than it appears at first glance - there are timezones, leap years, leap seconds, the difference between astronomical and atomic time, and so on and so forth.

Desktop accidentally flooded with jpegs with dates in 1970,1980 I can't open them and if I trash them there are warnings. What can I do?

I was moving some photos to desktop and accidentally started the computer flooding the desktop with jpegs. I turned the computer off to stop it continuing. These jpegs cannot be opened and if I try to trash them it says they are being used or that it may damage something. They cannot be opened and info on them says dates like 1970, many years before I had a comptuer.
Can anyone help? How can I safely get rid of theses 100s of jpegs cluttering my desktop? Why did it happene? How to stop it recurring?

        int day = c.get(Calendar.DAY_OF_WEEK);
        Date d = new Date(year, month, day);
        System.out.println(d);
}i get 3906-09-06 as an output...please help

Date d = new Date(year, month, day);
The year is a number from 1900. So u need to substract 1900 from the value u got before.

Needed help regarding converting string to java.sql.Date format
