SQL Server :: Compare Retrieved With "updated" Fields
Oct 4, 2010
I have a web app that allows users to update their public facing information (bio, profile pics, etc). Once a user updates a piece of information, it needs to be held "pending" until an authorized admin user "approves" the change. I was thinking that I'd keep a table (called something like PendingHistory) which would hold the "pending" changes, then once approved (which requires TWO admin user to approve), I'll dump this data into the "real" tables that's responsible for displaying information to the public. Is there a way (I'm sure there has to be) to only store those fields that were changed? Some sort of comparison of the original field vs "new" so I don't have to save everything. I was hoping to make it as easy as possible for the admin crew, so that they could just get a view of "pending changes" vs the entire row of data. So basically I need something like this:

i want to compare my database value with my new updated value. what should i do ? e.g : on page load i am excuting one procedure which bring 10 columns and fill it against the 10 fields using for loop on the page. then i am changing value of two columns. ok. when i press update button then there is one more procedure which updates all the new and old columns into database. Its working fine. just i want to know that, should i update only two columns(which are modified) insted of updating all 10 columns ? Is there any csharp code that brings my page load columns into array and then compare it with new ones and updates only those columns which are mismatch with array. i am not sure but there is some way to do this.
I have 2 image columns in SQL server table.How can I compare the image columns to see if they are equal? I am using VB in asp.net or I could do it in SQL too.
If imagefield1 = imagefield2 then 'Code here end if
I'm new to JQuery and recently started using the validation plug-in. I have a scenario where user have one of those type in your password and confirm your password textboxes. This is easilly accomplished with the "equalTo" rule how every my requirement is that once this failed the error message should be displayed and the textbox cleared. I assume there is no short and easy way todo this without writing javascript functions. point me in the right direction with a url or example.
Then a question to all you JQuery experts I've noticed "digits" and "number" to me they do the same thing? If not then explain the differance to me. Also how do I do a validation group in jQuery, similar to the asp.net validation controls assigned to a group and activated by a certain valodation enabled button?
But, name may not have changed, it may only be a change to the content textbox.
The problem is that entity framework treats Name as changed just because I've set it's value, regardless of whether I've set exactly the same value or not.
Ideally, I would like EF to only mark things as changed if they genuinely have changed.
Dim reader As SqlDataReader reader = cmd.ExecuteReader Dim XML As String = reader("records").ToString
I've executed the command in SQL server and I get a result string with length of 54781But when I execute it via .NET and assign it to the XML variable, the length of XML is always 2033...so now Im thinking that the result column "records" cannot exceed this length for some reason...
i have a web application which which proccesses some request on some data that client selects, when the client selects more than 20 objects and clicks on proceed the client recieves this error, because the server takes a long time to process, however if the records are less and hence a timely response is recieved, no such error comes?

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?
I want to compare smalldatetime values in my db to a calendar date. I'm not getting any value from dr[0] when I debug and put breakpoint in code below. Same thing if I select 'dateStart' instead of 'count(*)'. Any ideas?

I have login control, when user completes the registration process, thn i want him to login into his profile but when he login i want to check the plan for which he registered, i have three plans basic, professional, and enterprise, according to that only he will be redirected to different plan, how can i do that, i used below code but its not working:
public void login() { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["constring"].ToString()); con.Open(); SqlCommand cmd = new SqlCommand("select Email, Password, Edition from SN005ClientTable where Email='" + txtEmail.Text + "' and Password='" + txtPwd.Text + "' ", con);
I have UpdatePanel1 inside of which I have a Server Side Call Button - BT_ServerCall.
Then I have a second UpdatePanel2 which has a listbox (populated in pageload with some items) , a label, a hidden field, and a Button which calls a javascript function BT_JSCall.
Finally there is a second listbox which does not reside in an updatepanel.
i am populating the second listbox with values selected in the first listbox. then I click the BT_JSCall button which calls the javascript function copy_to_hidden_field() , inside which I take the values from the second listbox and store them as a concatenated string in the hidden field. Lastly, in the javascript function I simulate a button click event on BT_ServerCall. At this point I hit the server side method for the click event and I extract the value from the hidden field. lastly I change the value of the hidden field and also copy the new value to the label. I call the updatepanel2 update method (both updatepanels are set to updatemode conditional).
here is the problem: neither the hidden field nor the label get updated with the new text.
here is code

public partial class WebForm3 : System.Web.UI.Page
I have unexpectedly found that I cannot access my data tables from VS 2008. A window comes up saying "The server version is not supported. Only servers up to Microsoft SQL server 2005 are supported". Also, as a consequence I imagine, two web sites which refer to datatable have stopped working.
Has my ISP updated to an SQL version that VS 2008 can't handle ?
In one of my stored procedure I have to compare two nvarchar datatype values.The values containing both numerical and characters.Which function should I write? And one more problem i.e if a number containing zeros in starting ,I should also match including zeros.But not omit zeros.
<asp:CompareValidator ID="cpvBirthDate" Type="Date" ControlToValidate="txtBirthDate" Operator="DataTypeCheck" runat="server" ErrorMessage="Please enter a valid date in this format mm-dd-yy"> <img src="Images/ExclamationMark.gif" alt="Please enter a valid date in this format mm-dd-yy" /> </asp:CompareValidator>
It works on the clientside fine, but if a user has javascript disabled then it accepts 071873 which is not a date. Do I need to write a specific serverside function for this validator to work?
