please try datediff

Liju Sankar · Answer 2 · 2012-03-28T04:20:00

Please use the

SQL

datepart paramter in DATEDIFF ( datepart , startdate , enddate )

SQL

datepart

Is the part of startdate and enddate that specifies the type of boundary crossed. The following table lists all valid datepart arguments. User-defined variable equivalents are not valid.

Solution 3

Try this

SQL

SELECT DATEDIFF(dd, '3/26/2012', '3/28/2012') [Day Difference]

Result

SQL

Day Difference
--------------
2

Other datepart types

SQL

SELECT DATEDIFF(HH, '3/26/2012 3:30 PM', '3/26/2012 5:30 PM') [Hour Difference]
SELECT DATEDIFF(MINUTE, '3/26/2012 3:30 PM', '3/26/2012 5:30 PM') [minute difference]

Similary you can add keywords like Month, SS (Second), MS (millisecond), MCS (microsecond) for differences

I am doing like that where tasksDurationDays column has no. of days calculated by datediff of startdate and enddate.Is there some other way in c# or sql,I am using view to fill datatable.
dataSet.Tables["Tasks"].Columns.Add("TaskDuration", typeof(TimeSpan));
foreach (DataRow dr in dataSet.Tables["Tasks"].Rows)
{
dr["TaskDuration"] = TimeSpan.FromDays(dr["TaskDurationDays"].ToString().ToInt32());
}

Solution 2

TimeSpan diff = DateTime.Now.AddHours(2) - DateTime.Now;

TimeSpan has properties for time, hours, minutes, seconds, etc. What more do you need?

Thanks,
I am using view in database,there is two datetime columns and on their datediff I have to calculate time.

You tagged this as C# not database. Provide accurate information up front and you will get better answers. DATEDIFF has time. What is it that you want?

Solution 1

C#

DateTime startdts = new DateTime(29, 3, 2012, 14, 0, 0);
TimeSpan span = DateTime.Now - startdts;

Then you can use span.Total...... to get the total time difference of the two DateTime objects.

Hope this helps.
