SQL Server :: Compare Row From Previous Row In A Single Table?
Jan 5, 2011
My table is :
ID Dated
-------------------------
1 2010-01-01 00:00:00.000
2 2010-02-20 00:00:00.000
3 2010-09-15 00:00:00.000
4 2010-04-03 00:00:00.000
5 2010-11-09 00:00:00.000
6 2010-12-11 00:00:00.000
7 2011-01-18 00:00:00.000
Now I want to find(select) Id and dated columns which have a difference of 4 months(less or greater than) from previous ID (row).
Expected Result
ID Dated
1 2010-01-01 00:00:00.000
2 2010-02-20 00:00:00.000
6 2010-12-11 00:00:00.000
7 2011-01-18 00:00:00.000

I would like to use ASP.net, C# and SQL to display a list of games with radio buttons like below (the x is the radio). One team can be selected for each game.
game 1: x team 4 x team 2
game 2: x team 6 x team 1
game 3: x team 5 x team 3
The game list is stored in a table in an SQL database. So far, I can pull all teams into one big RadioButtonList. I cannot figure out how to create multiple RadioButtonList controls from this single table of games. Does anyone know how this can be accomplished - or reference to an example / tutorial that accomplishes something like this?

When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?
<asp:Content ID="Content4" ContentPlaceHolderID="leftForm" Runat="Server">
<asp:Label ID="lblStartTimeEnter" runat="server" Text="Start Time:" Width="100px"/>
<asp:TextBox ID="txtStartTime"runat="server" MaxLength="50" Width="250"/>
</asp:content>
<asp:Content ID="Content4" ContentPlaceHolderID="rightForm" Runat="Server">
<asp:label ID="lblEndDateEnter" CssClass="formMargin labelInput" runat="server" Text="End Date:" Width="100px"/>
<asp:TextBox ID="txtEndDate" CssClass="formMargin" runat="server" MaxLength="20" Width="250" ClientIDMode="Static"/>
<asp:CompareValidator ID="cvlDate" runat="server" ControlToValidate="txtEndDate" ControlToCompare="txtStartDate" Operator="GreaterThan" Type="Date" ErrorMessage="Start Date must be before End Date" > *</asp:CompareValidator>
</asp:content>

I'm trying to write code for a function that checks dates in a db table and finds the ones that has passed. Example:
tbl Occasion
ID dateStart (smalldatetime) dateStop (smalldatetime)
1 2011-03-29 13:00:00 2011-03-29 14:00:00 //this one won't pass until midnight
2 2011-03-27 17:00:00 2011-03-29 18:00:00 //this one has passed
[Code]....
The formats of 'datevalue' and 'dateStart'/'dateStop' in db are the same, do I need to convert them anyway?
