Say I have a table called "Visits", and I want to create a query that counts the visits per day. The way I would accomplish this would be to create a query as such:
SELECT Count(VisitId) as VisitCount, Convert(varchar(32), VisitDateTime, 101) as VisitDate
FROM Visits
WHERE VisitDateTime BETWEEN '10/1/2010' AND '10/5/2010'
GROUP BY VisitDate
The problem I am trying to overcome is that if there were no visits in a given day, that day does not show in my list. For example, if there were 3 visits on the 1st, 2 on the 2nd, none on the 3rd, and 5 on the 4th, my result set would look like:
3, 10/1/2010
2, 10/2/2010
4, 10/4/2010
How can I create my query so that I get all days in the date range listed in the result set regardless of whether the VisitCount is zero?
I have a datatable and I want to have a view on it with unique dates. The thing is that I want the date to be unique if the year,month and day are the same, I dont care for the exact time.
I now have:
Dim dtUniqueDates As System.Data.DataTable
dtUniqueDates = dt.DefaultView.ToTable(True, "updatedate")
So in this case 12 february 2011 13:54 is different from 12 february 2011 15:54. But since year,month and day are the same I want them to be unique.
I am geting a json value with multiple stateid amd more statid are multiple,but I want stateid only unique(distinct) in jquery array.
View 2 RepliesI'm not really much of a programmer but I've been working on something in visual web developer and VB...'ve got an asp.net page with a fileupload control and two buttons. One button is used to upload the file and then the other button does something else which involves accessing the file name of the uploaded file.
This is straight forward enough if you just use static text but I wanted to create a unique file name for the upload so thought about using a date/time value for this and delcaring it as a variable?This works great but how does the second button then access this file name? If I use the same variable name declared earlier it just generates a new one especially if mins and secs were used?
I'm not sure if that makes sense? But I'm basically wanting to create a unique file name for the uploaded file and then store that in a variable so it can be accessed by the other button? Without the variable constantly updating to a new ID?
I'm having arraylist to add student info but i have to create unique id per record below is my class.Student

In given code finally I want to populate unique values at runtime in 2 drop downlist.
