In my data set I have a string value 1:43 PM. I would like to convert this to 13:34. I have set the text box property to this
But it does not make any change the time still shows as 1:43 PM. IS there anyway to make this conversion?
It looks like your time is coming in as a string so you would need to convert the string before you could get the time.
=CDATE("1:43 PM")
=CDATE(Fields!TIME_FIELD.Value)
and then your format property will format it to the desired result.

in my ms access query i have a column named [Hours & Minutes]. the column values are taken as "(((tblA.TotalMins) &':'&(mid (tblA.TotalHours,4,2))) as [Hours & Minutes]". it is a string type i want to sum it so i want to convert it into a HH:MM format for calculation or any format for calculation
Your expression doesn't make sense, as it seems to interchange hours:minutes to minuttes:hours.
If your field holds text like "22:45", this can easily be converted:
DateValue([TextTime]) As TrueTime
If you have a field for hours and another for minutes, use TimeSerial:
TimeSerial([TotalHours],[TotalMinutes],0) As TrueTime
I am trying to get just the AM/PM part from a DateTime column in SSRS. I have tried both =Right(Fields!Start_Time.Value,2) and =Format(Fields!Start_Time.Value,"tt") and both gives me A3s and P3s. I have also tried =IIF(DatePart("hour",Fields!Start_Time.Value) < 12, "AM", "PM") which just displayed the original DateTime, unformatted. What is causing this and how do I just get the AM/PM part?
Are you sure that your field is a DATE/TIME or does it just look like a Date/Time field?
The only thing I can think of is that your field isn't actually a date/time type but just looks like one.
Try using CDATE to convert the Start Time field to a Date/Time that can be Formatted.
=Format(CDATE(Fields!Start_Time.Value),"tt")
UPDATE:
After reviewing your comments, I think you are putting the formula in the FORMAT property and not in the Expression. The way the question was written, I assumed you were populating the text box's Expression with the data formatted using the FORMAT function. If set the text box to the Start Time field and want to format using the FORMAT property, you would just put the in the FORMAT (tt) and not use the FORMAT function.
Try: =IIF( Mid(Fields!Start_Time.Value,12,2) < 12 , "AM", "PM")
I'm trying to iterate on a DataSet, this contain a results of query such as SELECT * FROM tb 1, now the first three field contains a date, the format saved in the database table is this:
yyyy-MM-dd HH:mm:ss
but the code return this:
yyyy/MM/dd HH:mm:ss
in particular this:
For z = 1 To ds.Tables(0).Columns.Count - 1
Console.WriteLine(ds.Tables(0).Rows(x)(z).ToString())
Next
So I need to recognize if the current string have this format: yyyy/MM/dd HH:mm:ss and parse it into: yyyy-MM-dd HH:mm:ss I tough to a regex pattern for recognize it, but I'm not an expert of regex. Anyway, if there is another solution I'll glad to see. Note that only the first three value and the last one of the table is date, the other values aren't date but contain integer or other string value.
Dates do not have a format. From MSDN:
Represents an instant in time, typically expressed as a date and time of day.
...
Time values are measured in 100-nanosecond units called ticks, and a particular date is the number of ticks since 12:00 midnight, January 1, 0001 A.D. (C.E.) in the GregorianCalendar calendar...For example, a ticks value of 31241376000000000L represents the date, Friday, January 01, 0100 12:00:00 midnight.
So, a DateTime is just a Big Number. Representing them as "dd/MM/yyyy" is part of the magic of the DateTime type. Part of the issue is this:
Console.WriteLine(ds.Tables(0).Rows(x)(z).ToString())
Row items are Object. It wont act like a DateTime type unless/until you get it into a DateTime variable. That print as a DateTime simple because the DataTable knows the underlying type; but it will use the default format for your Culture. This makes it look like dates have a built in format (or even that the "format changed" if you tried to set it to something), but you are a human and 635882810022222112L would not make sense to most of us.
To change the output style, you first need to get it into a DateTime variable. Apparently, a preliminary step is to determine if an arbitrary column is a Date. Rather than testing the "format" of the output, test the underlying data type. This does assume a proper DateTime column in the DataTable:
If ds.Tables(0).Columns(n).DataType = GetType(DateTime) Then
'...
End If
' Or:
If ds.Tables(0).Rows(x)(z).GetType Is GetType(DateTime) Then
'...
End If
Then to change the display, first get it into a DateTime variable:
Dim dt As DateTime
If ds.Tables(0).Rows(x)(z).GetType Is GetType(DateTime) Then
dt = Convert.ToDateTime(ds.Tables(0).Rows(x)(z))
' cant change "format" but you can change how it displays:
Console.WriteLine(dt.ToLongDateString)
Console.WriteLine(dt.ToString("yyyy-MM-dd HH:mm tt"))
Console.WriteLine(dt.ToString("dd MMM, yyyy"))
End If
An easier way to get and convert to DateTime is to use the Field(Of T) extension:
Dim dt = ds.Tables(0).Rows(x).Field(Of DateTime)(y)
when I peform the insert usually do this: Date.Now.ToString("yyyy-MM-dd HH:mm:ss") so I apply a format to date to insert... if I don't format correctly the date as I shown I get this value 0000-00-00 00:00:00
That doesn't apply a format to a date. It converts the DateTime to a string. While "yyyy-MM-dd HH:mm:ss" is the correct format to use when passing date data as a string to MySql, it is not needed. The MySQL Data provider knows how to convert a Net DateTime var to the data MySql needs/wants and back again -- that's its job.
' this will work fine
cmd.Parameters.Add("#SomeDate", MySqlDbType.DateTime).Value = myDateTimeVar
The format requirement you read about is the what you need to use in the MySql shell or WorkBench UI because you are entering text/string there...from the keyboard. It does not mean code must convert DateTime variables to string in a specific format for storing.
I ended up using this
Try
Dim theDate As DateTime = dr.Item(colName)
Return theDate
Catch
' do something
End Try
I would be happy to see a better method.
Based off of what you seem to be asking a simple replace would do
For z = 1 To ds.Tables(0).Columns.Count - 1
Console.WriteLine(ds.Tables(0).Rows(x)(z).ToString().Replace("/","-"))
Next
if it comes in with / they are changed to - if it comes in with - they remain intact.
Depending on the flexibility you want in this, it may be necessary to TryParse to ensure that the value you're working with is actually a valid 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'm trying to specify dd/mm/yyyy dateformat for date/time parameter in SSRS 2008 R2.
My computers datetime format is mm-dd-yyyy.
My requirement is, i want to show date format at dd/mm/yyyy irrespective of the system/server date format.
I've already tried CDate(Format(Today,"dd/mm/yyyy")) which didn't work. one very strange thing i observed is, it shows dd/mm/yyyy format only for dates on or before 12-MM-yyyy, and 13 onwards it gives error: Conversion from string '25-04-2014' to type Date is not valid. (Possibly it is trying to map 25(daypart) with MM-dd-yyyy (month part)) which is out of range of total months i.e. 12)
my research on internet says it is a bug in BIDS 2008.
What do i do to display date as dd/mm/yyyy ??
I don't have enough reputation to comment, but I did notice that you failed to put "()" after "Today". If I'm not mistaken you must put Today() for that function to work. Also, you might want to try putting CDate Around the Today() function. You shouldn't need it, but it's worth a shot. Also, for some odd reason, in my experience, you must capitalize MM for format to work correctly.
Like #Aditaya said, it should be =format(Today(),"dd/MM/yyyy")
The expression I usually use is:
=FormatDateTime(Fields!Date.Value, DateFormat.ShortDate)
However, this may be region specific.
Rather than writing an expression to do the formatting, you can also use the Textbox Format Property. But first you need to make sure that the data is in a date format. So use the CDate function on your column like this:
=CDate(Fields!Date.Value)
Then in the textbox properties go to the Number tab. Select Date for the category. Then you can select whichever format you want or use a Custom format. This will change how the column displays when you run the report.
