I have one problem in my tool. I am using one MySQL table called calendar. From this table I am fetching some date values. The format of date in calendar table is yyyy-mm-dd. But in my system having dd-mmm-yy. In my c# application I fetched the date from the Calendar and If I displayed the date in c# application means date format(2012-10-05) changed to system format(05-oct-12). But I need to display in yyyy-mm-dd format. I don't know how to solve this problem.
To display DateTime in specific format, you can specify the format in .ToString() method like:
DateTime dt = DateTime.Now; //your DateTime variable
Console.WriteLine(dt.ToString("yyyy-mm-ddd"));

I have a column in my database that is of type DATE.
I inserted the date via Java using the method: Date.valueOF(LocalDate.now()).
r.setRkd(Date.valueOf(LocalDate.now()));
The entry is correct because the exact date appears in the table.
rkd

2022-03-02
The problem is that when I call the service I don't get the correct date back in the JSON, but a series of numbersenter code here.
"rkd": 1646175600000
Do you know how I can print the correct date in my JSON?
Thank you in advance.
That number you are getting is the milliseconds equivalent to the date you have stored. As far as I know, dates, in general, are stored as milliseconds and displayed in different formats, e.g. YYYY-MM-DD
If you need to display it in date format there should be a method to do it depending on the specific language that you're using.
I want to transform the value of fields name and Date using pentaho(kattle) and store it in standard format in any table.
For example
id,name,f_n,Date
1,j_vick,03-05-2015
2,jo_vick,04,08,2016
3,Arn_jonnn_vick,05,07,2017
Now I want to transform it using pentaho(kattle) IDE and store it in data base like below:
id,name,Date
1,john_vick,03/05/2015
2,john_vick,04/08/2016
3,Arn_john_vick,05/07/2017
I don't want the transformation steps concern with extraction database storage.
The date format is just some clothing of a value. Just read it with Kettle and store it as is. The database will store it in its proper internal binary format anyway.
Unless, you have to store them explicitly as varchar. In that case, use the Metadata tab of the Select Value step. Define your column as Date and specify the format as dd/MM/yyyy or MM/dd/yyyy. It will be kept internally as a Date, and converted into a String with the selected format at the last moment.
You also seam to have an other problem: the day, month and year are in three columns. The easiest way is to use a Modified Java Script Value step, in which you define a new column date = new Date(year, month, year), with type Date, and let Kettle handle with the format.
Maybe you have mixed input, in which case you can use a Filter or a Swtich step, based on weather you have something in the day and month column.
When that is done, you can make a job that runs the transformation on all the tables. You have an example in the sample/jobs/process all tables furnished with the Pentaho Data Integrator (aka Kettle).
I am using the StimulsoftJS designer and adding a Group header. The grouping condition is based on a date which comes from my json object as a string. How can format it into a date so I can use WeekOFYear? Since the date is in a string format in the json and I dont see a tryParseToDate function, what is the best way to do this?
So, the answer to this is to edit the data source in the designer and select the datatype as DATETIME.
I have one datetimepicker which custom format MM/dd/yyyy h:mm tt
I have database and has a column "Date_Time" the value of the DateTimePicker is saved to the column Date_Time formatted like this MM/dd/yyyy h:mm tt
now i want to get the Time only not the entire value of datetimepicker just the hh:mm tt from the column Date_Time
SORRY FOR MY GRAMMAR
How about DateTime.TimeOfDay?
It returns the time that has elapsed since midnight (which is what h:mm tt stands for in your code).
Dim Time As TimeSpan = DateTimePicker1.Value.TimeOfDay 'Would return for example 3:14 PM
The answer above is right.
If you need to get time string, you can use also another way, which includes a formating:
Dim myTimeString = DateTimePicker1.value.ToString("hh:mm")
You can do that for any part of the DateTime value.
You are heading for a new problem. If you zero out the Date portion and store the result to a DateTime column, you will end up storing something like: 0001-01-01 16:43:12. A column defined as DateTime will always have a Date, as will a DateTime variable.
The first problem may be getting MySQL to accept a non-Date in a DateTime column. Using a column defined as DateTime(3), mine throws a generic fatal error exception trying to store just a TimeSpan to it:
cmd.Parameters.Add("#p3", MySqlDbType.DateTime).Value = DateTime.Now.TimeOfDay
cmd.ExecuteNonQuery()
If MySqlDbType.Time is used as the type, I get an exception that the time is an invalid value for the column...and it is.
If you manage to store it somehow, the next problem will be when/if you want to put that value back in a DateTimePicker: the minimum date you can enter is 1/1/1753 (first full year of the current calendar). So your DateTime var with the Date zeroed out wont work. You'll first have to restore the date portion, but the Date, Year etc are all readonly.
Solution 1
Define the column as Time(0) which will store hours, minutes and seconds. Use the value in the parens to specify fractional seconds, for instance Time(3) will also store milliseconds. When you read the data, store it to a TimeSpan.
Then in your UI use a different control, otherwise you have the same problem - adding some Date data to it to make it usable in a DateTimePicker
Solution 2
Use a DateTimePicker and a DateTime column, but just ignore the Date portion in your code. This will allow you to use what is in the Database as is with the control.
You can get the time selected with DateTime.TimeOfDay but storing and reusing it may be problematic.
I have a date column in my table, which will display a date as '17-MAR-15' format. Now I need to pass the date as 'DD-MM-YYYY(17-03-2015)' format to the Java API call. How can I pass this date parameter in that format?
You should take a look at: DATE_FORMAT
But basically what you do is this:
SELECT DATE_FORMAT(dateColumn, '%d-%m-%Y') FROM xyz;
Edit: Well, should have waited until I was really awake to answer, but if you happen to convert your date column to the date type this is how you would get the date in the specified format.
