SQL Server :: List All Dates In Date Range When Selecting Count
Oct 11, 2010
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 am trying to do this form that counts the number of records that are completed in a certain date range. I just want the user to place his date range and have it return the count as a Label. Here's what I have so far, I'm not 100% sure how to correctly place the user inputed variables into the Query.
It keeps returning "System.Data.SqlClient.SqlCommand"

When a user selects an item from dropdownlist ,, certain dates (from DB) gets selected on Calendar automatically with the color pink >> This is working FINE The problem happens after that, when i want to select any other date >> the dates which were selected automatically before (that came from DB) get deselected !! I want them to stay selected, so i know which are the dates that already saved in DB ! So, the calendar is removing the programmed selected dates upon selecting a new date on the calendar object.

[Code]....
I want to select dates that also fallin the range. Heres the scenario: I have an event from 01/20/2010 TO 01/25/2010. So right now it would only return a date of 01/20/2010. How could I return 01/20/2010, 01/21/2010 , 01/22/2010, 01/23/2010, 01/24/2010, 01/25/2010? Mind you only a start and end date are in the database.

I am generating multi-series graphs with the date along the X-Axis. The problem is that not all of the series in the graph have the same dates in the date range. Meaning that if I choose 1 Feb through 30 Apr that one series may have data that starts at 1 Feb but only goes through the end of March but another series may have data for the entire date range. This skews the charts I need to create. Go, given the date range taken at the begining of the query I'd like to generate a list of dates and populate the data to be graphed, padding those series with 0's for those dates that have no data.

I wanted to select 2 dates from a Calendar and display the selected dates and their difference between the two selected dates in labels. I put a calender in .aspx file and in coding:
public static int counter;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Calendar1_SelectionChanged(object sender, EventArgs e)
{
myLabel.Text = "";
//Label1.Text = "You selected: <br />";
//Now, we assign the variable value in the text box
foreach (DateTime dt in Calendar1.SelectedDates)
{
counter++;
Calendar1.SelectedDates.Add(dt);
Label1.Text += dt.ToShortDateString() + "<br />";
myLabel.Text = counter.ToString() + "days";
}
}
The problem is i cant not stop selecting dates after selecting 2 randomly dates.

This must be easier than this: I want to highlight a range of dates, in this case: All dates after today. The only control I can see which allows me to wire-in to a date based X-Axis is the Stripline So, I get today's date minus my earliest date in the dataset in days... No problems. So to set up the Stripline I try something like:
[Code]....
and ends up looking like: Today is where the second shade begins. This is fine, but it is looping over 12 months. The number of days since it began is 399 days. I was hoping that would have actually meant the offset was 399 days. Am I trying too hard with the wrong class? Is there something else I should be using?

I am using AjaxCalendar Toolkit :
<asp:TextBox CssClass="form-control" ReadOnly="true" runat="server" id="StartTime"></asp:TextBox> <asp:CalendarExtender ID="Start_CalendarExtender" runat="server" Enabled="True" TargetControlID="StartTime">
</asp:CalendarExtender>
<asp:TextBox CssClass="form-control" ReadOnly="true" runat="server" id="EndTime"></asp:TextBox> <asp:CalendarExtender ID="Start_CalendarExtender" runat="server" Enabled="True" TargetControlID="EndTime">
</asp:CalendarExtender>
And On Page Load i have done this to avoid selecting previoud dates in start date :
protected void Page_Load(object sender, EventArgs e)
{
Start_CalendarExtender.StartDate = DateTime.Now;
}
Now i want to do that user cannot select end date less than start date , e.g if he choose 2-July-2014 ( as a start date) then he could not choose (1-July-2014) as End date , dates prior to Start Date must get disabled in End Date Calendar Extender.

I want to calculate the number of HOLIDAYS between two given dates. For example, to count the number of 'Fridays' and 'Saturdays' and any other holiday (can get from another table) in between two given dates.
For example,
Start Date: 16/07/2010
End Date: 22/07/2010
Holiday: 19/07/2010
OUTPUT: 3 Holidays (Since there are only two Fridays and Saturdays and one Holiday)
do also note that it must include count if the starting day or ending day is a holiday.
