I need to convert a SQL Server timestamp format (stored on Timestamp java data type) into this format yyyy-mm-ddThh:mm:ss.sssZ (it's the date format parsed by Alfresco)
How can I do it?
thanks for your time!

Try this SimpleDateFormat:
SimpleDateFormat sdf = new SimpleDateFormat( "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" );
String yourformattedDate = sdf.format(yourDate);
You could try and get the time (in ms) from your TimeStamp instance, create a Date instance and use the DateFormatter class to format it anyway you want. That is, assuming DateFormatter supports the format you want.

I'm trying to upload the current UTC time to a date "field" in Parse. How can I do this?
DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("utc"));
String utcTime = df.format(new Date());
message.put("lastReplyUpdatedAt", utcTime);
message.saveInBackground();
Unfortunately, I can't seem to get the right imports to work for the classes above so I can't construct my String. What can I do here? Also I'm not sure if Parse would even accept that String. Are there any special formats I need to consider?
Pass a Date
From the Parse platform documentation, pass a Date object rather than a String.
Date myDate = new Date();
message.put("lastReplyUpdatedAt", myDate);
message.saveInBackground();
I have bunch of dates in a format like Jan. 14,2014,Apr. 20,2014,Aug. 14,2014 etc,. which are extracted from a set of PDF documents.
My Problem
I added the above dates to a mysql column with Column Datatype as Date using java (by PreparedStatement).
....
st.SetDate(3,"Jan. 14,2014");
....
I added the datas using ExecuteQuery.
But when program executes an error message returned by MySql stating that the date formats are incompatible with MySql column type) Date..
My Question
How to convert this above mentioned date formats into mysql compatible Date formats ?
By your current posted code:
st.SetDate(3,"Jan. 14,2014");
This does not even compile. You could try getting a new Date object from a String (since this is what you're trying to accomplish), so use a SimpleDateFormat for this:
SimpleDateFormat sdf = new SimpleDateFormat("MMM. dd,yyyy");
Date date = sdf.parse("Jan. 14,2014");
st.setDate(3, new java.sql.Date(date.getTime()));
//rest of your code...
Similar to this, you can parse time or date and time into a java.util.Date using SimpleDateFormat and then convert it to the respective class java.sql.Time and java.sql.Timestamp using date.getTime().
Also note that you can p̶a̶s̶s̶ retrieve a java.util.Date object reference to PreparedStatement#getDate (and getTime and getTimestamp) since java.sql.Date, java.sql.Time and java.sql.Timestamp extend from java.util.Date. For more info, please refer here: Date vs TimeStamp vs calendar?
Assuming the column type supports a Date value, you could use a SimpleDateFormat to parse the String values to a java.util.Date and create a java.sql.Date which can be applied to the setDate method...
SimpleDateFormat sdf = new SimpleDateFormat("MMM. dd,yyyy");
Date date = sdf.parse("Jan. 14,2014");
java.sql.Date sqlDate = new java.sql.Date(date.getTime());
Check it SimpleDateFormat for more details
One possible solution is to use the String datatype instead of date in your table.
Use SimpleDateFormat to get the string representation of the date to a Date Object.
This date object can then be used to feed the set date method of the prepared statement.
SimpleDateFormat sdf = new SimpleDateFormat(....)
java.util.Date date = sdf.parse(....);
preparedStmt.setDate(...., date);
first convert the java.util.Date to java.sql.Date then try to set the Java.sql.Date
you can use this logic to convert
If your date is String then first convert it into Java.util.Date type either by using the SimpleDateFormat or DateFormat
If u want to use a DateFormat you can use it also:
But this changes the expected date format depending on the locale settings of the machine it's running on.
If you have a specific date format, you can use SimpleDateFormat:
Date d = new SimpleDateFormat("MMM. dd,yyyy").parse("Jan. 14,2014");
java.sql.Date sqlDate = new java.sql.Date(d.getTime());
I don't really think this all java stuff is necessary. You can simply use this very easy sql process to insert date: NOW() in mysql query like INSERT INTO table_name(c1,c2,datecolumn) VALUES('value1','value2',NOW()); It is much simplier I think :D
I am developing a spring application and in one of my controller i have following lines to parse from string to date and format the parsed date to required format. But again i need to parse back formatted string into date without using any SimpleDateFormat, so is it possible to do so ?
SimpleDateFormat dateFormat = new SimpleDateFormat("MM-dd-yyyy");
SimpleDateFormat dateFormat2 = new SimpleDateFormat("yyyy-MM-dd");
Date pick=dateFormat.parse(request.getParameter("pickDate"));
String pick_date=dateFormat2.format(pick);
Edit:
I found in the wikipedia that china has the locale yyyy-MM-dd. check this reference date format by country
set locale to China you'll get the required date format
Try this
String d1="12-27-2010";
Stirng[] splitdata=d1.split("-");
int month=Integer.parseInt(splitdata[0]);
int day=Integer.parseInt(splitdata[1]);
int year=Integer.parseInt(splitdata[2]);
Calender cal=Calender.getInstance(Locale.CHINA);
cal.set(year,month,day);
Date d=cal.getTime();
This should work
If you know your data format you can do that. by using simple string operations
Ex:
if your data format is
MM-dd-yyyy
then you can convert to yyyy-MM-dd like this
String d1="12-27-2010";
Stirng[] splitdata=d1.split("-");
String s2= splitdate[2]+"-"+splitdate[0]+"-"+splitdate[1];
You can use Concatenation Operator(+) for that
Yes possible; just write the code to do the parsing. Should not be that difficult ...
I managed in JAVA to store a calendar into a mysql DATETIME field
To fetch this value
entry.date = Calendar.getInstance(TimeZone.getTimeZone("UT"));
entry.date.setTime(rs.getDate(DBBLogEntries.entDate));
Where the entry.date is a java.util.Calendar
In the database the value is this: '2012-07-07 07:18:46'
I store all date values in a unique timezone in the db. ready to make all the extra work required to add or substract hours depending on the country from wich the request is comming.
The problem is that it brings the date but doesn't seem to brinng me the time.
Any sugestion please?
Thanks in advance.
Probably because Java has a different date format than mysql format(YYYY-MM-DD HH:MM:SS)
Visit the link :

You may use SimpleDateFormat as follows.
java.util.Date dt = new java.util.Date();
java.text.SimpleDateFormat sdf =
new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String dateTime = sdf.format(dt);
You should read a timestamp from the ResultSet object.
java.sql.Timestamp ts = rs.getTimestamp( DBBLogEntries.entDate );
Which returns a Timestamp instance that includes date and time.
don't use Java.util.Date ,use the Java.sql.Date.
Are you using the MySql DATE type? This does not preserve the time component.

Alternatively how are you retrieving the date from the db?
I am trying to use setDate() in a PreparedStatement, however the date that I have is in the format of 2008-07-31. The code is:
pstmt.setDate(f++, (Date) DateFormat.getDateInstance(DateFormat.DEFAULT).parse(value.substring(0, 10)));
However, it gives me the error:
Exception in thread "main" java.text.ParseException: Unparseable date: "2008-07-31"
Why is this?
If you have a very specific date, don't ask Java to use a default date format - set it yourself.
For example:
DateFormat parser = new SimpleDateFormat("yyyy-MM-dd");
Date date = parser.parse(value.substring(0, 10));
You should also potentially set the time zone of the parser... my guess is that UTC is the most appropriate time zone here.
Note that this has nothing to do with prepared statements as such - it's just date parsing.
(As an alternative to using DateFormat and SimpleDateFormat, you could use Joda Time which has a nicer API and thread-safe formatters/parsers. You can ask Joda Time to convert from its own types to Date values. Possibly overkill if you only need it for parsing here, but if you're doing anything else with dates, it's well worth looking into.)
You need make sure the default DateFormat is in yyyy-MM-dd format (usually it's a config in OS), or you can use SimpleDateFormat or java.sql.Date to parse date string.
java.util.Date d;
SimpleDateFormat sdf = new SimpleDateFormat ("yyyy-MM-dd");
d = sdf.parse ("2008-07-31");
// or
d = java.sql.Date.valueOf ("2008-07-31");
or, you could just set parameter as String, if the underlying database driver support the VARCHAR/CHAR to DATE conversion.
DateFormat.DEFAULT points to MEDIUM format and MEDIUM format looks like Jan 12, 1952. So, you may have create a SimpleDateFormat object with the format you are using.
I think there is mismatch in the format of the date that you are providing as input and the format in which you have specified while formatting which is default in your case.
SimpleDateFormat parser = new SimpleDateFormay("yyyy-MM-dd");
Try using the same format for both the dates.
First convert String to Date and then set that to PreparedStatement. Check with below code.
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-mm-dd");
Date convertedDate = dateFormat.parse(dateString);
I'd use
pstmt.setDate(f++,
new java.sql.Date(
new SimpleDateFormat("yyyy-MM-dd")
.parse(value.substring(0, 10))
.getTime()
)
);
