how to convert flex date objec to sql date and time,
i am using AMFPHP to connect with mysql
need help
cheers
actually the date to string of flex will give you the format like
Day Mon Date HH:MM:SS TZD YYYY
but sql is like
2010-12-14 00:00:00
so what you do is make a string of the sql format and just pass as object to AMFPHP that will save it to sql
and sql will accept it as date time
private function dateToString(date:Date):String
{
var dateString:String = date.fullYear+"-"+(date.month+1)+"-"+date.date+" "+date.hours+":"+date.minutes+":"+date.seconds;
return dateString;
}//end function
cheers....
I suppose, the date is sent as string. In that case, use mysql function STR_TO_DATE()

currently, i have a datetime object
DateTime theDateTime = DateTime.ParseExact(dateAndTime, "d MMMM yyyy hh:mm tt", provider);
which successfully converts it into a datetime (from a string) to become for example :
7/6/2012 9:30:00 AM
How do i convert this to become 2012/07/06 09:30:00 (24hr format)? So that i can insert it into the database using C#??
PS: I'm using Sybase SQL Anywhere 12, and from what I've read, they neeed the format to be in year/months/day and the time to be in 24hr format right? Please correct me if I'm wrong.
The DateTime itself does not have a format. The date and time are stored internally as a number. Usually the classes of the database provider take care of converting a DateTime to the correct format.
If Sybase will only accept the date formatted as a string you will need to use the DateTime.ToString method and format it with the correct format string.
How are you building your insert command? Are you using database parameters or just building a string containing the insert statement?
SQL Anywhere 12 has a default date format of YYYY-MM-DD HH:NN:SS.SSS
This can be configured/changed with the timestamp_format database option however:
timestamp_format option
The setting can be permanently changed through SQL like:
SET OPTION PUBLIC.timestamp_format = '<format here>';
Or temporarily changed (per connection basis) like:
SET TEMPORARY OPTION timestamp_format = '<format here>';
Of course, if you already have a datetime object in your code, you should be able to pass the value into a parameterized query. It doesn't have to be passed as a string.
I have an ASP.NET program that is writing date to an SQLExpress Database date field in DD/MM/YYYY.
When I look at the data in SQL Express it is stored as mm/dd/yyyy.
How can I configure it to store in DD/MM/YYYY format?
This is not possible, as the date is internally stored as a number, the DD/MM/YYYY or MM/DD/YYYY format is only the display format of the data. You can, however, change the way the data are converted to a string by SQL functions...
You are seeing the a rendered, localised version of an internal date representation (numbers of days since 01 Jan 1900 basically).
Don't worry about it. You'll get date back to your client (in an internal date representation) and this can be formatted how you like there.
Store the data normally. When you retrieve the data, do something like this on the code:
dateField.ToString("dd/MM/yyyy")
And your result will be: 11/04/2011
Maybe you can select that like this:
select CONVERT(varchar(12) , getdate(), 103 )
I have a textbox which displays the date as 01-May-2011 but the database coumis in format of datetime ... how to enter date in date time column of database. ..
how to wite the sqlquery for this ?
You can convert that format to a DateTime like this
string dateString = "01-May-2011";
string format = "dd-MMM-yyyy";
var result = DateTime.ParseExact(dateString, format, CultureInfo.InvariantCulture);
if you're using LINQ to SQL or even ADO with a parameter of type DateTime, the conversion to a format that SQL understands will be done automatically for you.
If you're building the SQL by concatenating a string manually (not recommended!) you should try to reconvert to a string in the format 'yyyyMMdddd' (corrected as per AdaTheDev's comment, notice the single quotes). Other formats may or may not be recognized by sql depending on the language settings on both your client and your SQL Server
SQL Server is pretty good about taking in datetime values. If you pass the date as a parameter you can put quotes around it ('01-May-2011') and ignore the time. The database will automatically fill in a default time so that you don't have to worry about it.
Pass field value as nvarchar to database and use following to cast it to datetime.
Declare #dt nvarchar(20)
SET #dt = '01-May-2011'
select cast(#dt as datetime)
One thing to be aware of is that dates w/o time will be interpreted as May 1 2011 12AM. IE, without a time specified, SQL Server will always set the time to midnight. So if you have just the date as a field and you want records from May 1, you can't do
WHERE datefield = '5/1/2011'
This will find records where the datefield is May 1st Midnight. You have to do
WHERE datefield >= '5/1/2011' and datefield < '5/2/2011'
This doesn't really pertain to your question, but I've seen it trip up a LOT of people. Myself included.
Just convert it to dateTime
DateTime _ConvertedDate = Convert.ToDateTime(txtDate.Text);
this converts into datetime
I'm using MS SQL 2000, VS2008, MVC and C#.
I'm trying to insert and update some data using stored procedures.
Some columns are of type datetime.
Regional settings on both server and client are set to Dutch (Belgium)
This means the default date format is dd/mm/yyyy.
When i try to insert or update with a date of eg. 28/03/2009, I get following errors:
Insert:
Error converting data type nvarchar to datetime
Update:
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value
When I try with a date like 01/03/2009, I get no errors but the date is saved as 03/01/2009, which is the US date format.
This is typical behaviour for problems with regional settings. But both are set to Dutch (Belgium).
Why does it save dates in the US format?
What am i missing here?
Thanks!

You should be inserting data into the database using a DateTime object, not a string. Your client-side code should convert the client's date entry to a DateTime object using the client's regional settings, then the DateTime struct should be added to the parameter that is ultimately sent into the database.
The SQL Instance has it's own locale setting, by default "us_english"
Now, this usually happens if you pushing using varchar rather than native datetime to store data values. If your code/tables use datetime columns and you define parameters as datetime then you won't get errors.
i had this problem too, its something to do with the date format for you SQL server,
i solved it by formatting the date string to be inserted like so
DateTime.Now.ToString("MM/dd/yyyy HH:mm")
hope that helps
All above suggestions are correct but I find if you are adding a datetime as a string/varchar the safest way is in the format 'YYYY-MM-DD'
So eg.
Update MyTable
Set MyDate = '2010-03-01'
I am setting the locale of my .net application via:
string userLocale = Web.Helpers.LocaleHelpers.GetBestRFC3066Locale(this.Context.Request.UserLanguages);
if (userLocale != String.Empty)
{
System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.CreateSpecificCulture(userLocale);
System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(userLocale);
}
This works well, so my dates will be displayed in the format based upon the locale i.e.
12/10/2009 for en-gb
and
10/12/2009 for us
However when I persist my dates via LinqToSql I need to store these dates in a common format.
Currently when a U.S. user is running the app the date stored in the DB is in U.S. format and when an U.K. user uses the app, its in a U.K. format.
Any suggestions on how best to achieve this?
Store the date as a datetime value in SQL Server. Then you don't run into a conversion problem.
Brannon has the right solution there. Once you have a variable in a datetime format in SQL you can convert it to other datetime formats using the CONVERT T-SQL keyword
